ILLUSTRIOUS SIR, AND MOST WORTHY FRIEND, -- So painful to me was the separation from you the other day after our meeting in your retreat at Rhijnsburg, that it is my first endeavour, now that I am returned to England, to renew, as far as is possible by correspondence, my intercourse with you. Solid learning, conjoined with courtesy and refinement of manners (wherewith both nature and art have most amply endowed you), carries with it such charms as to command the love of every honourable and liberally-educated man. Let us then, most excellent sir, join hands in sincere friendship, and let us foster the feeling with every zealous endeavour and kind office in our power. Whatever my poor means can furnish I beg you to look on as your own. Allow me in return to claim a share in the riches of your talents, as I may do without inflicting any loss on yourself.

We conversed at Rhijnsburg of God, of extension, of infinite thought, of the differences and agreements between these, of the nature of the connection between the human soul and body, and further, of the principles of the Cartesian and Baconian philosophies.

But, as we then spoke of these great questions merely cursorily and by the way, and as my mind has been not a little tormented with them since, I will appeal to the rights of our newly cemented friendship, and most affectionately beg you to give me at somewhat greater length your opinion on the subjects I have mentioned. On two points especially I ask for enlightenment, if I may presume so far; first: In what do you place the true distinction between thought and matter? secondly: What do you consider to be the chief defects in the Cartesian and Baconian philosophies, and how do you think they might best, be removed, and something more sound substituted? The more freely you write to me on these and similar subjects, the more closely will you tie the bonds of our friendship, and the stricter will be the obligation laid on me to repay you, as far as possible, with similar services.

There is at present in the press a collection of physiological discourses written by an Englishman (Robert Boyle) of noble family and distinguished learning) They treat of the nature and elasticity of the air, as proved by forty-three experiments; also of its fluidity, solidity, and other analogous matters. As soon as the work is published, I shall make a point of sending it to you by any friend who may be crossing the sea. Meanwhile, farewell, and remember your friend, who is

Yours, in all affection and zeal,
HENRY 0LDENBURG

Illustrious Sir,

How pleasant your friendship is to me, you may yourself judge, if your modesty will allow you to reflect on the abundance of your own excellences. Indeed the thought of these makes me seem not a little bold in entering into such a compact, the more so when I consider that between friends all things, and especially things spiritual, ought to be in common. However, this must lie at the charge of your modesty and kindness rather than of myself. You have been willing to lower yourself through the former and to fill me with the abundance of the latter, till I am no longer afraid to accept the close friendship, which you hold out to me, and which you deign to ask of me in return; no effort on my part shall be spared to render it lasting.

As for my mental endowments, such as they are, I would willingly allow you to share them, even though I knew it would be to my own great hindrance. But this is not meant as an excuse for denying to you what you ask by the rights of friendship. I will therefore endeavour to explain my opinions on the topics you touched on; though I scarcely hope, unless your kindness intervene, that I shall thus draw the bonds of our friendship closer.

I will then begin by speaking briefly of God, Whom I define as a Being consisting in infinite attributes, whereof each is infinite or supremely perfect after its kind. You must observe that by attribute I mean everything, which is conceived through itself and in itself, so that the conception of it does not involve the conception of anything else. For instance, extension is conceived through itself and in itself, but motion is not. The latter is conceived through something else, for the conception of it implies extension.

That the definition above given of God is true appears from the fact, that by God we mean a Being supremely perfect and absolutely infinite. That such a Being exists may easily be proved from the definition; but as this is not the place for such proof, I will pass it over. What I am bound here to prove, in order to satisfy the first inquiry of my distinguished questioner, are the following consequences; first that in the universe there cannot exist two substances without their differing utterly in essence; secondly that substance cannot be produced or created - existence pertains to its actual essence; thirdly, that all substance must be infinite or supremely perfect after its kind.

When these points have been demonstrated, my distinguished questioner will readily perceive my drift, if he reflects at the same time on the definition of God. In order to prove them clearly and briefly, I can think of nothing better than to submit them to the bar of your judgment proved in the geometrical method. I therefore enclose them separately and await your verdict upon them

Again, you ask me what errors I detect in the Cartesian and Baconian philosophies. It is not my custom to expose the errors of others, nevertheless I will yield to your request. The first and the greatest error is, that these philosophers have strayed so far from the knowledge of the first cause and origin of all things; the second is, that they did not know the true nature of the human mind; the third, that they never grasped the true cause of error. The necessity for correct knowledge on these three points can only be ignored by persons completely devoid of learningand training.

That they have wandered astray from the knowledge of the first cause, and of the human mind, may easily be gathered from the truth of the three propositions given above; I therefore devote myself entirely to the demonstration of the third error. Of Bacon I shall say very little, for he speaks very confusedly on the point, and works out scarcely any proofs: he simply narrates. In the first place he assumes, that the human intellect is liable to err, not only through the fallibility of the senses, but also solely through its own nature, and that it frames its conceptions in accordance with the analogy of its own nature, not with the analogy of the universe, so that it is like a mirror receiving rays from external objects unequally, and mingling its own nature with the nature of things, etc.

Secondly, that the human intellect is, by reason of its own nature, prone to abstractions; such things as are in flux it feigns to be constant, etc.

Thirdly, that the human intellect continually augments, and is unable to come to a stand or to rest content. The other causes which he assigns may all be reduced to the one Cartesian principle, that the human will is free and more extensive than the intellect, or, as Verulam himself more confusedly puts it, that the understanding is not a dry light, but receives infusion from the will. (We may here observe that Verulam often employs intellect as synonymous with mind, differing in this respect from Descartes). This cause, then, leaving aside the others as unimportant, I shall show to be false; indeed its falsity would be evident to its supporters, if they would consider, that will in general differs from this or that particular volition in the same wayas whiteness differs from this or that white object, or humanity from this or that man. It is, therefore, as impossible to conceive, that will is the cause of a given volition, as to conceive that humanity is the cause of Peter and Paul.

Hence, as will is merely an entity of the reason, and cannot be called the cause of particular volitions, and as some cause is needed for the existence of such volitions, these latter cannot be called free, but are necessarily such as they are determined by their causes; lastly, according to Descartes, errors are themselves particular volitions; hence it necessarily follows that errors, or, in other words, particular volitions, are not free, but are determined by external causes, and in nowise by the will. This is what I undertook to prove.

3 (3). Oldenburg to Spinoza, September 27, 1661

MOST EXCELLENT FRIEND, -- Your learned letter has been delivered to me, and read with great pleasure. I highly approve of your geometrical method of proof, but I must set it down to my dulness, that I cannot follow with readiness what you set forth with such accuracy. Suffer me, then, I beg, to expose the slowness of my understanding, while I put the following questions, and beg of you to answer them.

First. Do you clearly and indisputably understand solely from the definition you have given of God, that such a Being exists? For my part, when I reflect that definitions contain only the conceptions formed by our minds, and that our mind forms many conceptions of things which do not exist, and is very fertile in multiplying and amplifying what it has conceived, I do not yet see, that from the conception I have of God I can infer God's existence. I am able by a mental combination of all the perfections I perceive in men, in animals, in vegetables, in minerals, &c., to conceive and to form an idea of some single substance uniting in itself all such excellences; indeed my mind is able to multiply and augment such excellences indefinitely; it may thus figure forth for itself a most perfect and excellent Being, but there would be no reason thence to conclude that such a Being actually exists.

Secondly. I wish to ask, whether you think it unquestionable, that body cannot be limited by thought, or thought by body; seeing that it still remains undecided, what thought is, whether it be a physical motion or a spiritual act quite distinct from body?

Thirdly. Do you reckon the axioms, which you have to me, as indemonstrable principles known by the light of nature and needing no proof? Perhaps the first is of this nature, but I do not see how the other three can be placed in a like category. The second assumes that nothing exists in the universe save substances and accidents, but many persons would say that time and place cannot be classed either as one or the other. Your third axiom, that things having different attributes have no quality in common, is so far from being clear to me, that its contrary seems to be shown in the whole universe. All things known to us agree in certain respects and differ in others. Lastly, your fourth axiom, that when things have no quality in common, one cannot be produced by another, is not so plain to my groping intelligence as to stand in need of no further illumination. God has nothing actually in common with created things, yet nearly all of us believe Him to be their cause.

As you see that in my opinion your axioms are not established beyond all the assaults of doubt, you will readily gather that the propositions you have based upon them do not appear to me absolutely firm. The more I reflect upon them, the more are doubts suggested to my mind concerning them.

As to the first, I submit that two men are two substances with the same attribute, inasmuch as both are rational; whence I infer that there can be two substances with the same attribute.

As to the second, I opine that, as nothing can be its own cause, it is hardly within the scope of our intellect to pronounce on the truth of the proposition, that substance cannot be produced even by any other substance. Such a proposition asserts all substances to be self-caused, and all and each to be independent of one another, thus making so many gods, and therefore denying the first cause of all things. This, I willingly confess, I cannot understand, unless you will be kind enough to explain your theory on this sublime subject somewhat more fully and simply, informing me what may be the origin and mode of production of substances, and the mutual interdependence and subordination of things. I most strenuously beg and conjure you by that friendship which we have entered into, to answer me freely and faithfully on these points; you may rest assured, that everything which you think fit to communicate to me will remain untampered with and safe, for I will never allow anything to become public through me to your hurt or disadvantage. In our Philosophical society we proceed diligently as far as opportunity offers with our experiments and observations, lingering over the compilation of the history of mechanic arts, with the idea that the forms and qualities of things can best be explained from mechanical principles, and that all natural effects can be produced through motion, shape, and consistency, without reference to inexplicable forms or occult qualities, which are but the refuge of ignorance.

I will send the book I promised, whenever the Dutch Ambassadors send (as they frequently do) a messenger to the Hague, or whenever some other friend whom I can trust goes your way. I beg you to excuse my prolixity and freedom, and simply ask you to take in good part, as one friend from another, the straightforward and unpolished reply I have sent to your letter, believing me to be without deceit or affectation,

Yours most faithfully,
HENRY OLDENBURG
London, 27 Sept., 1661.

4 (4). Spinoza to Oldenburg, October, 1661

Illustrious Sir,

As I was starting for Amsterdam, where I intend staying for a week or two, I received your most welcome letter, and noted the objections you raise to the three propositions I sent you. Not having time to reply fully, I will confine myself to these three.

To the first I answer, that not from every definition does the existence of the thing defined follow, but only (as I showed in a note appended to the three propositions) from the definition or idea of an attribute, that is (as I explained fully in the definition given of God) of a thing conceived through and in itself. The reason for this distinction was pointed out, if I mistake not, in the above-mentioned note sufficiently clearly at any rate for a philosopher, who is assumed to be aware of the difference between a fiction and a clear and distinct idea, and also of the truth of the axiom that every definition or clear and distinct idea is true. When this has been duly noted, I do not see what more is required for the solution of your first question.

I therefore proceed to the solution of the second, wherein you seem to admit that, if thought does not belong to the nature of extension, then extension will not be limited by thought; your doubt only involves the example given. But observe, I beg, if we say that extension is not limited by extension but by thought, is not this the same as saying that extension is not infinite absolutely, but only as far as extension is concerned, in other words, infinite after its kind? But you say: perhaps thought is a corporeal action: be it so, though I by no means grant it: you, at any rate, will not deny that extension, in so far as it is extension, is not thought, and this is all that is required for explaining my definition and proving the third proposition.

Thirdly. You proceed to object, that my axioms ought not to be ranked as universal notions. I will not dispute this point with you; but you further hesitate as to their truth, seeming to desire to show that their contrary is more probable. Consider, I beg, the definition which I gave of substance and attribute, for on that they all depend. When I say that I mean by substance that which is conceived through and in itself; and that I mean by modification or accident that, which is in something else, and is; conceived through that wherein it is, evidently it follows. that substance is by nature prior to its accidents. For without the former the latter can neither be nor be conceived. Secondly, it follows that, besides substances and accidents, nothing exists really or externally to the intellect. For everything is conceived either through itself or through something else, and the conception of it either involves or does not involve the conception of something else. Thirdly, it follows that things which possess different attributes have nothing in common. For by attribute I have explained that I mean something, of which the conception does not involve the conception of anything else. Fourthly and lastly, it follows that, if two things have nothing in common, one cannot be the cause of the other. For, as there would be nothing in common between the effect and the cause, the whole effect would spring from nothing. As for your contention that God has nothing actually in common with created things, I have maintained the exact opposite in my definition. I said that God is a Being consisting of infinite attributes, whereof each one is infinite or supremely perfect after its kind. With regard to what you say concerning my first proposition, I beg you, my friend, to bear in mind, that men are not created but born, and that their bodies already exist before birth, though under different forms. You draw the conclusion, wherein I fully concur, that, if one particle of matter be annihilated, the whole of extension would forthwith vanish. My second proposition does not make many gods but only one, to wit, a Being consisting of infinite attributes, etc.

9 (27). Spinoza to de Vries, February, 1663

Respected Friend,

I have received your long wished for letter, for which, and for your affection towards me, I heartily thank you. Your long absence has been no less grievous to me than to you; yet in the meantime I rejoice that my trifling studies are of profit to you and our friends. For thus while you are away, I in my absence speak to you. You need not envy my fellow-lodger. There is no one who is more displeasing to me, nor against whom I have been more anxiously on my guard; and therefore I would have you and all my acquaintance warned not to communicate my opinions to him, except when he has come to maturer years. So far he is too childish and inconstant, and is fonder of novelty than of truth. But I hope, that in a few years he will amend these childish faults. Indeed I am almost sure of it, as far as I can judge from his nature. And so his temperament bids me like him.

As for the questions propounded in your club, which is wisely enough ordered, I see that your difficulties arise from not distinguishing between kinds of definition: that is, between a definition serving to explain a thing, of which the essence only is sought and in question, and a definition which is put forward only for purposes of inquiry. The former having a definite object ought to be true, the latter need not. For instance, if someone asks me for a description of Solomon's temple, I am bound to give him a true description, unless I want to talk nonsense with him. But if I have constructed, in my mind, a temple which I desire to build, and infer from the description of it that I must buy such and such a site and so many thousand stones and other materials, will any sane person tell me that I have drawn a wrong conclusion because my definition is possibly untrue? or will anyone ask me to prove my definition? Such a person would simply be telling me, that I had not conceived that which I had conceived, or be requiring me to prove, that I had conceived that which I had conceived; in fact, evidently trifling. Hence a definition either explains a thing, in so far as it is external to the intellect, in which case it ought to be true and only to differ from a proposition or an axiom in being concerned merely with the essences of things, or the modifications of things, whereas the latter has a wider scope and extends also to eternal truths. Or else it explains a thing, as it is conceived or can be conceived by us; and then it differs from an axiom or proposition, inasmuch as it only requires to be conceived absolutely, and not like an axiom as true. Hence a bad definition is one which is not conceived. To explain my meaning, I will take Borel's example - a man saying that two straight lines enclosing a space shall be called figurals. If the man means by a straight line the same as the rest of the world means by a curved line, his definition is good (for by the definition would be meant some such figure as (), or the like); so long as he does not afterwards mean a square or other kind of figure. But, if he attaches the ordinary meaning to the words straight line, the thing is evidently inconceivable, and therefore there is no definition. These considerations are plainly confused by Borel, to whose opinion you incline. I give another example, the one you cite at the end of your letter. If I say that each substance has only one attribute, this is an unsupported statement and needs proof. But, if I say that I mean by substance that which consists in only one attribute, the definition will be good, so long as entities consisting of several attributes are afterwards styled by some name other than substance. When you say that I do not prove, that substance (or being) may have several attributes, you do not perhaps pay attention to the proofs given. I adduced two: - First, that nothing is plainer to us, than that every being may be conceived by us under some attribute, and that the more reality or essence a given being has, the more attributes may be attributed to it. Hence a being absolutely infinite must be defined, etc. Secondly, and I think this is the stronger proof of the two, the more attributes I assign to any being, the more am I compelled to assign to it existence; in other words, the more I conceive it as true. The contrary would evidently result, if I were feigning a chimera or some such being.

Your remark, that you cannot conceive thought except as consisting in ideas, because, when ideas are removed, thought is annihilated, springs, I think, from the fact that while you, a thinking thing, do as you say, you abstract all your thoughts and conceptions. It is no marvel that, when you have abstracted all your thoughts and conceptions, you have nothing left for thinking with. On the general subject I think I have shown sufficiently clearly and plainly, that the intellect, although infinite, belongs to nature regarded as passive rather than nature regarded as active (ad naturam naturatam, non vero ad naturam naturantem).

However, I do not see how this helps towards understanding the third definition, nor what difficulty the latter presents. It runs, if I mistake not, as follows: By substance I mean that, which is in itself and is conceived through itself; that is, of which the conception does not involve the conception of anything else. By attribute I mean the same thing, except it is called attribute with respect to the understanding, which attributes to substance the particular nature aforesaid. This definition, I repeat, explains with sufficient clearness what I wish to signify by substance or attribute. You desire, though there is no need, that I should illustrate by an example, how one and the same thing can be stamped with two names. In order not to seem miserly, I will give you two. First, I say that by Israel is meant the third patriarch; I mean the same by Jacob, the name Jacob being given, because the patriarch in question had caught hold of the heel of his brother. Secondly, by a colourless surface I mean a surface, which reflects all rays of light without altering them. I mean the same by a white surface, with this difference, that a surface is called white in reference to a man looking at it, etc.

10 (28). Spinoza to de Vries, March, 1663

Respected Friend,

You ask me if we have need of experience, in order to know whether the definition of a given attribute is true. To this I answer, that we never need experience, except in cases when the existence of the thing cannot be inferred from its definition, as, for instance, the existence of modes (which cannot be inferred from their definition); experience is not needed, when the existence of the things in question is not distinguished from their essence, and is therefore inferred from their definition. This can never be taught us by any experience, for experience does not teach us any essences of things; the utmost it can do is to set our mind thinking about definite essences only. Wherefore, when the existence of attributes does not differ from their essence, no experience is capable of attaining it for us.

To your further question, whether things and their modifications are eternal truths, I answer: Certainly. If you ask me, why I do not call them eternal truths, I answer, in order to distinguish them, in accordance with general usage, from those propositions, which do not make manifest any particular thing or modification of a thing; for example, nothing comes from nothing. These and such like propositions are, I repeat, called eternal truths simply, the meaning merely being, that they have no standpoint external to the mind, etc.

12 (29). Spinoza to Meyer, April 20, 1663

Dearest Friend,

I have received two letters from you, one dated Jan. 11, delivered to me by our friend, N. N., the other dated March 26, sent by some unknown friend to Leyden. They were both most welcome to me, especially as I gathered from them, that all goes well with you, and that you are often mindful of me. I also owe and repay you the warmest thanks for the courtesy and consideration, with which you have always been kind enough to treat me: I hope you will believe, that I am in no less degree devoted to you, as, when occasion offers, I will always endeavour to prove, as far as my poor powers will admit. As a first proof, I will do my best to answer the questions you ask in your letters. You request me to tell you, what I think about the infinite; I will most readily do so.

Everyone regards the question of the infinite as most difficult, if not insoluble, through not making a distinction between that which must be infinite from its very nature, or in virtue of its definition, and that which has no limits, not in virtue of its essence, but in virtue of its cause; and also through not distinguishing between that which is called infinite, because it has no limits, and that, of which the parts cannot be equalled or expressed by any number, though the greatest and least magnitude of the whole may be known; and, lastly, through not distinguishing between that, which can be understood but not imagined, and that which can also be imagined. If these distinctions, I repeat, had been attended to, inquirers would not have been overwhelmed with such a vast crowd of difficulties. They would then clearly have understood, what kind of infinite is indivisible and possesses no parts; and what kind, on the other hand, may be divided without involving a contradiction in terms. They would further have understood, what kind of infinite may, without solecism, be conceived greater than another infinite, and what kind cannot be so conceived. All this will plainly appear from what I am about to say.

However, I will first briefly explain the terms substance, mode, eternity, and duration.

The points to be noted concerning substance are these: First, that existence appertains to its essence; in other words, that solely from its essence and definition its existence follows. This, if I remember rightly, I have already proved to you by word of mouth, without the aid of any other propositions. Secondly, as a consequence of the above, that substance is not manifold, but single: there cannot be two of the same nature. Thirdly, every substance must be conceived as infinite.

The modifications of substance I call modes. Their definition, in so far as it is not identical with that of substance, cannot involve any existence. Hence, though they exist, we can conceive them as non-existent. From this it follows, that, when we are regarding only the essence of modes, and not the order of the whole of nature, we cannot conclude from their present existence, that they will exist or not exist in the future, or that they have existed or not existed in the past; whence it is abundantly clear, that we conceive the existence of substance as entirely different from the existence of modes. From this difference arises the distinction between eternity and duration. Duration is only applicable to the existence of modes; eternity is applicable to the existence of substance, that is, the infinite faculty of existence or being (infinitum existendi sive (invita Latinitate) essendi fruitionem).

From what has been said it is quite clear that, when, as is most often the case, we are regarding only the essence of modes and not the order of nature, we may freely limit the existence and duration of modes without destroying the conception we have formed of them; we may conceive them as greater or less, or may divide them into parts. Eternity and substance, being only conceivable as infinite, cannot be thus treated without our conception of them being destroyed. Wherefore it is mere foolishness, or even insanity, to say that extended substance is made up of parts or bodies really distinct from one another. It is as though one should attempt by the aggregation and addition of many circles to make up a square, or a triangle, or something of totally different essence. Wherefore the whole heap of arguments, by which philosophers commonly endeavour to show that extended substance is finite, falls to the ground by its own weight. For all such persons suppose, that corporeal substance is made up of parts. In the same way, others, who have persuaded themselves that a line is made up of points, have been able to discover many arguments to show that a line is not infinitely divisible. If you ask, why we are by nature so prone to attempt to divide extended substance, I answer, that quantity is conceived by us in two ways, namely, by abstraction or superficially, as we imagine it by the aid of the senses, or as substance, which can only be accomplished through the understanding. So that, if we regard quantity as it exists in the imagination (and this is the more frequent and easy method), it will be found to be divisible, finite, composed of parts, and manifold. But, if we regard it as it is in the understanding, and the thing be conceived as it is in itself (which is very difficult), it will then, as I have sufficiently shown you before, be found to be infinite, indivisible, and single.

Again, from the fact that we can limit duration and quantity at our pleasure, when we conceive the latter abstractedly as apart from substance, and separate the former from the manner whereby it flows from things eternal, there arise time and measure; time for the purpose of limiting duration, measure for the purpose of limiting quantity, so that we may, as far as is possible, the more readily imagine them. Further, inasmuch as we separate the modifications of substance from substance itself, and reduce them to classes, so that we may, as far as is possible, the more readily imagine them, there arises number, whereby we limit them. Whence it is clearly to be seen, that measure, time, and number, are merely modes of thinking, or, rather, of imagining. It is not to be wondered at, therefore, that all, who have endeavoured to understand the course of nature by means of such notions, and without fully understanding even them, have entangled themselves so wondrously, that they have at last only been able to extricate themselves by breaking through every rule and admitting absurdities even of the grossest kind. For there are many things which cannot be conceived through the imagination but only through the understanding, for instance, substance, eternity, and the like; thus, if anyone tries to explain such things by means of conceptions which are mere aids to the imagination, he is simply assisting his imagination to run away with him. Nor can even the modes of substance ever be rightly understood, if we confuse them with entities of the kind mentioned, mere aids of the reason or imagination. In so doing we separate them from substance, and the mode of their derivation from eternity, without which they can never be rightly understood. To make the matter yet more clear, take the following example: when a man conceives of duration abstractedly, and, confusing it with time, begins to divide it into parts, he will never be able to understand how an hour, for instance, can elapse. For in order that an hour should elapse, it is necessary that its half should elapse first, and afterwards half of the remainder, and again half of the half of the remainder, and if you go on thus to infinity, subtracting the half of the residue, you will never be able to arrive at the end of the hour. Wherefore many, who are not accustomed to distinguish abstractions from realities, have ventured to assert that duration is made up of instants, and so in wishing to avoid Charybdis have fallen into Scylla. It is the same thing to make up duration out of instants, as it is to make number simply by adding up noughts.

Further, as it is evident from what has been said, that neither number, nor measure, nor time, being mere aids to the imagination, can be infinite (for, otherwise, number would not be number, nor measure measure, nor time time); it is hence abundantly evident, why many who confuse these three abstractions with realities, through being ignorant of the true nature of things, have actually denied the infinite.

CirclesThe wretchedness of their reasoning may be judged by mathematicians, who have never allowed themselves to be delayed a moment by arguments of this sort, in the case of things which they clearly and distinctly perceive. For not only have they come across many things, which cannot be expressed by number (thus showing the inadequacy of number for determining all things); but also they have found many things, which cannot be equalled by any number, but surpass every possible number. But they infer hence, that such things surpass enumeration, not because of the multitude of their component parts, but because their nature cannot, without manifest contradiction, be expressed in terms of number. As, for instance, in the case of two circles, non-concentric, whereof one encloses the other, no number can express the inequalities of distance which exist between the two circles, nor all the variations which matter in motion in the intervening space may undergo. This conclusion is not based on the excessive size of the intervening space. However small a portion of it we take, the inequalities of this small portion will surpass all numerical expression. Nor, again, is the conclusion based on the fact, as in other cases, that we do not know the maximum and the minimum of the said space. It springs simply from the fact, that the nature of the space between two non-concentric circles cannot be expressed in number. Therefore, he who would assign a numerical equivalent for the inequalities in question, would be bound, at the same time, to bring about that a circle should not be a circle.

The same result would take place - to return to my subject - if one were to wish to determine all the motions undergone by matter up to the present, by reducing them and their duration to a certain number and time. This would be the same as an attempt to deprive corporeal substance, which we cannot conceive except as existent, of its modifications, and to bring about that it should not possess the nature which it does possess. All this I could clearly demonstrate here, together with many other points touched on in this letter, but I deem it superfluous.

From all that has been said, it is abundantly evident that certain things are in their nature infinite, and can by no means be conceived as finite; whereas there are other things, infinite in virtue of the cause from which they are derived, which can, when conceived abstractedly, be divided into parts, and regarded as finite. Lastly, there are some which are called infinite or, if you prefer, indefinite, because they cannot be expressed in number, which may yet be conceived as greater or less. It does not follow that such are equal, because they are alike incapable of numerical expression. This is plain enough, from the example given, and many others.

Lastly, I have put briefly before you the causes of error and confusion, which have arisen concerning the question of the infinite. I have, if I mistake not, so explained them that no question concerning the infinite remains untreated, or cannot readily be solved from what I have said; wherefore, I do not think it worth while to detain you longer on the matter.

But I should like it first to be observed here, that the later Peripatetics have, I think, misunderstood the proof given by the ancients who sought to demonstrate the existence of God. This, as I find it in a certain Jew named Rabbi Ghasdai, runs as follows: If there be an infinite series of causes, all things which are, are caused. But nothing which is caused can exist necessarily in virtue of its own nature. Therefore there is nothing in nature, to whose essence existence necessarily belongs. But this is absurd. Therefore the premise is absurd also. Hence the force of the argument lies not in the impossibility of an actual infinite or an infinite series of causes; but only in the absurdity of the assumption that things, which do not necessarily exist by nature, are not conditioned for existence by a thing, which does by its own nature necessarily exist.

I would now pass on, for time presses, to your second letter: but I shall be able more conveniently to reply to its contents, when you are kind enough to pay me a visit. I therefore beg that you will come as soon as possible; the time for travelling is at hand. Enough. Farewell, and keep in remembrance Yours, &a.

13 (9). Spinoza to Oldenburg, July 17/27, 1663

Distinguished Sir,

I have at length received your long wished for letter, and am at liberty to answer it. But, before I do so, I will briefly tell you, what has prevented my replying before.

When I removed my household goods here in April, I set out for Amsterdam. While there certain friends asked me to impart to them a treatise containing, in brief, the second part of the principles of Descartes treated geometrically, together with some of the chief points treated of in metaphysics, which I had formerly dictated to a youth, to whom I did not wish to teach my own opinions openly. They further requested me, at the first opportunity, to compose a similar treatise on the first part. Wishing to oblige my friends, I at once set myself to the task, which I finished in a fortnight, and handed over to them. They then asked for leave to print it, which I readily granted on the condition that one of them should, under my supervision, clothe it in more elegant phraseology, and add a little preface warning readers that I do not acknowledge all the opinions there set forth as my own, inasmuch as I hold the exact contrary to much that is there written, illustrating the fact by one or two examples. All this the friend who took charge of the treatise promised to do, and this is the cause for my prolonged stay in Amsterdam.

Since I returned to this village, I have hardly been able to call my time my own, because of the friends who have been kind enough to visit me. At last, my dear friend, a moment has come, when I can relate these occurrences to you, and inform you why I allow this treatise to see the light. It may be that on this occasion some of those, who hold the foremost positions in my country, will be found desirous of seeing the rest of my writings, which I acknowledge as my own; they will thus take care that I am enabled to publish them without any danger of infringing the laws of the land. If this be as I think, I shall doubtless publish at once; if things fall out otherwise, I would rather be silent than obtrude my opinions on men, in defiance of my country, and thus render them hostile to me. I therefore hope, my friend, that you will not chafe at having to wait a short time longer; you shall then receive from me either the treatise printed, or the summary of it which you ask for. If meanwhile you would like to have one or two copies of the work now in the press, I will satisfy your wish, as soon as I know of it and of means to send the book conveniently.

15 (-). Spinoza to Meyer, August 3, 1663

Dear Friend,

The preface you sent me by our friend De Vries, I now send back to you by the same hand. Some few things, as you will see, I have marked in the margin; but yet a few remain, which I have judged it better to mention to you by letter.

First, where on page 4 you give the reader to know on what occasion I composed the first part; I would have you likewise explain there, or where you please, that I composed it within a fortnight. For when this is explained none will suppose the exposition to be so clear as that it cannot be bettered, and so they will not stick at obscurities in this and that phrase on which they may chance to stumble.

Secondly, I would have you explain, that when I prove many points otherwise than they be proved by Descartes, 'tis not to amend Descartes, but the better to preserve my order, and not to multiply axioms overmuch: and that for this same reason I prove many things which by Descartes are barely alleged without any proof, and must needs add other matters which Descartes let alone.

Lastly, will earnestly beseech you, as my especial friend, to let be everything you have written, towards the end against that creature, and wholly strike it out. And though many reasons determine me to this request, I will give but one. I would fain have all men readily believe that these matters are published for the common profit of the world, and that your sole motive in bringing out the book is the love of spreading the truth; and that it is accordingly all your study to make the work acceptable to all, to bid men, with all courtesy to the pursuit of genuine philosophy, and to consult their common advantage. Which every man will be ready to think when he sees that no one is attacked, nor anything advanced where any man can find the least offence. Notwithstanding, if afterwards the person you know of, or any other, be minded to display his ill will, then you may portray his life and character, and gain applause by it. So I ask that you will not refuse to be patient thus far, and suffer yourself to be entreated, and believe me wholly bounden to you, and

Yours with all affection,
B. de Spinoza.

Voorburg, 3 August, 1663.

Our friend De Vries had promised to take this with him; but seeing he knows not when he will return to you, I send it by another hand.

Along with this I send you part of the scholium to Prop. 27. Part 2. where page 75 begins, that you may hand it to the printer to be reprinted.

The matter I send you must of necessity be reprinted, and fourteen or fifteen lines added, which may easily be inserted.

17 (30).Spinoza to Balling, July 20, 1664

Beloved Friend,

Your last letter, written, if I mistake not, on the 26th of last month, has duly reached me. It caused me no small sorrow and solicitude, though the feeling sensibly diminished when I reflected on the good sense and fortitude, with which you have known how to despise the evils of fortune, or rather of opinion, at a time when they most bitterly assailed you. Yet my anxiety increases daily; I therefore beg and implore you by the claims of our friendship, that you will rouse yourself to write me a long letter. With regard to Omens, of which you make mention in telling me that, while your child was still healthy and strong, you heard groans like those he uttered when he was ill and shortly afterwards died, I should judge that these were not real groans, but only the effect of your imagination; for you say that, when you got up and composed yourself to listen, you did not hear them so clearly either as before or as afterwards, when you had fallen asleep again. This, I think, shows that the groans were purely due to the imagination, which, when it was unfettered and free, could imagine groans more forcibly and vividly than when you sat up in order to listen in a particular direction. I think I can both illustrate and confirm what I say by another occurrence, which befell me at Rhijnsburg last winter. When one morning, after the day had dawned, I woke up from a very unpleasant dream, the images, which had presented themselves to me in sleep, remained before my eyes just as vividly as though the things had been real, especially the image of a certain black and leprous Brazilian whom I had never seen before. This image disappeared for the most part when, in order to divert my thoughts, I cast my eyes on a book, or something else. But, as soon as I lifted my eyes again without fixing my attention on any particular object, the same image of this same negro appeared with the same vividness again and again, until the head of it gradually vanished. I say that the same thing, which occurred with regard to my inward sense of eight, occurred with your hearing; but as the causes were very different, your case was an omen and mine was not. The matter may be clearly grasped by means of what I am about to say. The effects of the imagination arise either from bodily or mental causes. I will proceed to prove this, in order not to be too long, solely from experience. We know that fevers and other bodily ailments are the causes of delirium, and that persons of stubborn disposition imagine nothing but quarrels, brawls, slaughterings, and the like. We also see that the imagination is to a certain extent determined by the character of the disposition, for, as we know by experience, it follows in the tracks of the understanding in every respect, and arranges its images and words, just as the understanding arranges its demonstrations and connects one with another; so that we are hardly at all able to say, what will not serve the imagination as a basis for some image or other. This being so, I say that no effects of imagination springing from physical causes can ever be omens of future events; inasmuch as their causes do not involve any future events. But the effects of imagination, or images originating in the mental disposition, may be omens of some future event; inasmuch as the mind may have a confused presentiment of the future. It may, therefore, imagine a future event as forcibly and vividly, as though it were present; for instance a father (to take an example resembling your own) loves his child so much, that he and the beloved child are, as it were, one and the same. And since (like that which I demonstrated on another occasion) there must necessarily exist in thought the idea of the essence of the child's states and their results, and since the father, through his union with his child, is a part of the said child, the soul of the father must necessarily participate in the ideal essence of the child and his states, and in their results, as I have shown at greater length elsewhere.

Again, as the soul of the father participates ideally in the consequences of his child's essence, he may (as I have said) sometimes imagine some of the said consequences as vividly as if they were present with him, provided that the following conditions are fulfilled: - I. If the occurrence in his son's career be remarkable. II. If it be capable of being readily imagined. III. If the time of its happening be not too remote. IV. If his body be sound, in respect not only of health but of freedom from every care or business which could outwardly trouble the senses. It may also assist the result, if we think of something which generally stimulates similar ideas. For instance, if while we are talking with this or that man we hear groans, it will generally happen that, when we think of the man again, the groans heard when we spoke with him will recur to our mind. This, dear friend, is my Opinion on the question you ask me. I have, I confess, been very brief, but I have furnished you with material for writing to me on the first opportunity, etc.

Voorburg, 20 July, 1664.

18 (31).Blyenbergh to Spinoza, December 12, 1664

Unknown Friend and Sir,

I have already read several times with attention your treatise and its appendix recently published. I should narrate to others more becomingly than to yourself the extreme solidity I found in it, and the pleasure with which I perused it. But I am unable to conceal my feelings from you, because the more frequently i study the work with attention, the more it pleases me, and I am constantly observing something which I had not before remarked. However, I will not too loudly extol its author, lest I should seem in this letter to be a flatterer. I am aware that the Gods grant all things to labor. Not to detain you too long with wondering who I may be, and how it comes to pass that one unknown to you takes the great liberty of writing to you, I will tell you that he is a man who is impelled by his longing for pure and unadulterated truth, and desires during this brief and frail life to fix his feet in the ways of science, so far as our human faculties will allow; one who in the persuit of truth has no goal before his eyes save truth herself; one who by his science seeks to obtain as a result of truth neither honor nor riches, but simple truth and tranquillity; one who, out of the whole circle of truths and sciences, takes delight in none other than in metaphysics, if not in all branches at any rate in some; one who places the whole delight of his life in the fact, that he can pass in the study of them his hours of ease and leisure. But no one, I rest assured, is so blessed as yourself, no one has carried his studies so far, and therefore no one has arrived at the pitch of perfection which, as I see from your work, you have attained. To add a last word, the present writer is one with whom you may gain a closer acquaintance,
if you choose to attach him to you by enlightening and interpenetrating, as it were, his halting meditations.

But I return to your treatise. While I found in it many things which tickled my palate vastly, some of them proved difficult to digest. Perhaps a stranger ought not to report to you his objections, the more so as I know not whether they will meet with your approval. This is the reason for my making these prefatory remarks, and asking you, if you can find leisure in the winter evenings, and, at the same time, will be willing to answer the difficulties which I find in your book, and to forward me the result, always under the condition that it does not interrupt any occupation of greater importance or pleasure; for I desire nothing more earnestly that to see the promise made in your book fulfilled by a more detailed exposition of your opinions. I should have communicated to you by word of mouth what I now commit to paper; but my ignorance of your address, the infectious disease, and my duties here, prevent me. I must defer the pleasure for the present.

However, in order that this letter may not be quite empty, and in the hope that it will not be displeasing to you, I will ask one question. You say in various passages in the " Principa," and in the "metaphysical Reflections," either as your own opinion, or as explained in the philosophy of Descartes, that creation and preservation are identical ( which is, indeed, so evident to those who have considered the question as to be a primary notion ); secondly, that God has not only created substance, but also motions in substance ---- in other words, that God, by a continuous act of creation preserves, not only substance in their normal state, but also the motion and the endeavors of substance. God, for instance, not only brings about by his immediate will and working ( whatever be the term employed ), that the soul should last and continue in its normal state; but he is also the cause of his will determining, in some way, the movement of the soul --- in other words, as God, by a continuous act of creation, brings about that things should remain in existence, so is he also the cause of the movements and endeavors existing in things. In fact, save God, there is no cause of motion. It therefore follows that God is not only the cause of the substance of mind, but also of every endeavor or motion of mind, which we call volition, as you frequently say. From this statement it seems to follow necessarily, either that there is no evil in motion or volition of the mind, or else that God directly brings about that evil. For that which we call evil comes to pass through the soul, and, consequently, through the immediate influence and concurrence of God. For instance, the soul of Adam wishes to eat of the forbidden fruit. It follows from what has been said above, not only that Adam forms this wish through the influence of God, but also, as will be presently be shown, that through that influence he formed it in that particular manner. Hence, either the act forbidden to Adam is not evil, inasmuch as God himself not only caused the wish, but also the manner of it, or else God directly brought about that which we call evil. Neither you nor Descartes seem to have solved this difficulty by saying that evil is a negative conception, and that, as such, God cannot bring it about. Whence, we may ask, came the wish to eat the forbidden fruit,or the wish of devils to be equal with God?

For since ( as you justly observe ) the will is not something different from the mind, but is only an endeavor or movement of the mind, the concurrence of God is as necessary to it as to the mind itself. Now the concurrence of God, as I gather from your writings, is merely the determining of a thing in a particular manner through the will of God. It follows that God concurs no less in an evil wish, in so far as it is evil, than in a good wish in so far as it is good, in other words he determines it. For the will of God being the absolute cause of all that exists, either in substance or in effort, seems to be also the primary cause of an evil wish, in so far as it is evil. Again, no exercise of volition takes place in us, that God has not known from all eternity. If we say that God does not know of a particular exercise of volition, we attribute to God imperfection. But how could God gain knowledge of it except from his decrees? Therefore his decrees are the cause of our volitions, and hence it seems also to follow that either an evil wish is not evil, or else that God is the direct cause of the evil and brings it about. There is no room here for the theological distinction between an act and the evil inherent in the act. For God decrees the mode of the act no less than the act,that is, God not only decreed that Adam should eat, but also that he should necessarily eat contrary to the command given. Thus it seems on all sides to follow, either that Adam's eating contrary to the command was not an evil, or else that God himself brought it to pass.

These, illustrious sir, are the questions in your treatise, which I am unable at present, to elucidate. Either alternative seems to me difficult of acceptance. However, I await a satisfactory answer from your keen judgment and learning, hoping to show you hereafter how deeply indebted I shall be to you. Be assured, illustrious sir, that I put these questions from no other motives than the desire for truth. I am a man of leisure, not tied to any profession, gaining my living by honest trade, and devoting my spare time to questions of this sort. I humbly hope that my difficulties will not be displeasing to you. If you are minded to send an answer, as I most ardently hope, write to, etc,

William De Blyenbergh.

19 (32). Spinoza to Blyenbergh, January 5, 1665

Unknown Friend,

I received, at Schiedam, on the 26th of December, your letter dated the 12th of December, enclosed in another written on the 24th of the same month. I gather from it your fervent love of truth, and your making it the aim of all your studies. This compelled me, though by no means otherwise unwilling, not only to grant your petition by answering all the questions you have sent, or may in future send, to the best of my ability, but also to impart to you everything in my power, which can conduce to further knowledge and sincere friendship. So far as in me lies, I value, above all other things out of my own control, the joining hands of friendship with men who are sincere lovers of truth. I believe that nothing in the world, of things outside our own control, brings more peace than the possibility of affectionate intercourse with such men; it is just as impossible that the love we bear them can be disturbed (inasmuch as it is founded on the desire each feels for the knowledge of truth), as that truth once perceived should not be assented to. It is, moreover, the highest and most pleasing source of happiness derivable from things not under our own control. Nothing save truth has power closely to unite different feelings and dispositions. I say nothing of the very great advantages which it brings, lest I should detain you too long on a subject which, doubtless, you know already. I have said thus much, in order to show you better how gladly I shall embrace this and any future opportunity of serving you.

In order to make the best of the present opportunity, I will at once proceed to answer your question. This seems to turn on the point that it seems to be clear, not only from God's providence, which is identical with His will, but also from God's co-operation and continuous creation of things, either that there are no such things as sin or evil, or that God directly brings sin and evil to pass. You do not, however, explain what you mean by evil. As far as one may judge from the example you give in the predetermined act of volition of Adam, you seem to mean by evil the actual exercise of volition, in so far as it is conceived as predetermined in a particular way, or in so far as it is repugnant to the command of God. Hence you conclude (and I agree with you if this be what you mean) that it is absurd to adopt either alternative, either that God brings to pass anything contrary to His own will, or that what is contrary to God's will can be good.

For my own part, I cannot admit that sin and evil have any positive existence, far less that anything can exist, or come to pass, contrary to the will of God. On the contrary, not only do I assert that sin has no positive existence, I also maintain that only in speaking improperly, or humanly, can we say that we sin against God, as in the expression that men offend God.

As to the first point, we know that whatsoever is, when considered in itself without regard to anything else, possesses perfection, extending in each thing as far as the limits of that thing's essence: for essence is nothing else. I take for an illustration the design or determined will of Adam to eat the forbidden fruit. This design or determined will, considered in itself alone, includes perfection in so far as it expresses reality; hence it may be inferred that we can only concede imperfection in things, when they are viewed in relation to other things possessing more reality: thus in Adam's decision, so long as we view it by itself and do not compare it with other things more perfect or exhibiting a more perfect state, we can find no imperfection: nay it may be compared with an infinity of other things far less perfect in this respect than itself, such as stones, stocks, etc. This, as a matter of fact, everyone grants. For we all admire in animals qualities which we regard with dislike and aversion in men, such as the pugnacity of bees, the jealousy of doves, etc.; these in human beings are despised, but are nevertheless considered to enhance the value of animals. This being so, it follows that sin, which indicates nothing save imperfection, cannot consist in anything that expresses reality, as we see in the case of Adam's decision and its execution.

Again, we cannot say that Adam's will is at variance with the law of God, and that it is evil because it is displeasing to God; for besides the fact that grave imperfection would be imputed to God, if we say that anything happens contrary to His will, or that He desires anything which He does not obtain, or that His nature resembled that of His creatures in having sympathy with some things more than others; such an occurrence would be at complete variance with the nature of the divine will.

The will of God is identical with His intellect, hence the former can no more be contravened than the latter; in other words, anything which should come to pass against His will must be of a nature to be contrary to His intellect, such, for instance, as a round square. Hence the will or decision of Adam regarded in itself was neither evil nor, properly speaking, against the will of God: it follows that God may-or rather, for the reason you call attention to, must-be its cause; not in so far as it was evil, for the evil in it consisted in the loss of the previous state of being which it entailed on Adam, and it is certain that loss has no positive existence, and is only so spoken of in respect to our and not God's understanding. The difficulty arises from the fact, that we give one and the same definition to all the individuals of a genus, as for instance all who have the outward appearance of men: we accordingly assume all things which are expressed by the same definition to be equally capable of attaining the highest perfection possible for the genus; when we find an individual whose actions are at variance with such perfection, we suppose him to be deprived of it, and to fall short of his nature. We should hardly act in this way, if we did not hark back to the definition and ascribe to the individual a nature in accordance with it. But as God does not know things through abstraction, or form general definitions of the kind above mentioned, and as things have no more reality than the divine understanding and power have put into them and actually endowed them with, it clearly follows that a state of privation can only be spoken of in relation to our intellect, not in relation to God.

Thus, as it seems to me, the difficulty is completely solved. However, in order to make the way still plainer, and remove every doubt, I deem it necessary to answer the two following difficulties: First, why Holy Scripture says that God wishes for the conversion of the wicked, and also why God forbade Adam to eat of the fruit when He had ordained the contrary? Secondly, that it seems to follow from what I have said, that the wicked by their pride, avarice, and deeds of desperation, worship God in no less degree than the good do by their nobleness, patience, love, etc., inasmuch as both execute God's will.

In answer to the first question, I observe that Scripture, being chiefly fitted for and beneficial to the multitude, speaks popularly after the fashion of men. For the multitude are incapable of grasping sublime conceptions. Hence I am persuaded that all matters, which God revealed to the prophets as necessary to salvation, are set down in the form of laws. With this understanding, the prophets invented whole parables, and represented God as a king and a law-giver, because He had revealed the means of salvation and perdition, and was their cause; the means which were simply causes they styled laws and wrote them down as such; salvation and perdition, which are simply effects necessarily resulting from the aforesaid means, they described as reward and punishment; framing their doctrines more in accordance with such parables than with actual truth. They constantly speak of God as resembling a man, as sometimes angry, sometimes merciful, now desiring what is future, now jealous and suspicious, even as deceived by the devil; so that philosophers and all who are above the law, that is, who follow after virtue, not in obedience to law, but through love, because it is the most excellent of all things, must not be hindered by such expressions.

Thus the command given to Adam consisted solely in this, that God revealed to Adam, that eating of the fruit brought about death; as He reveals to us, through our natural faculties, that poison is deadly. If you ask, for what object did He make this revelation, I answer, in order to render Adam to that extent more perfect in knowledge. Hence, to ask God why He had not bestowed on Adam a more perfect will, is just as absurd as to ask, why the circle has not been endowed with all the properties of a sphere. This follows clearly from what has been said, and I have also proved it in my Principles of Cartesian Philosophy, I.15.

As to the second difficulty, it is true that the wicked execute after their manner the will of God: but they cannot, therefore, be in any respect compared with the good. The more perfection a thing has, the more does it participate in the deity, and the more does it express perfection. Thus, as the good have incomparably more perfection than the bad, their virtue cannot be likened to the virtue of the wicked, inasmuch as the wicked lack the love of God, which proceeds from the knowledge of God, and by which alone we are, according to our human understanding, called the servants of God. The wicked, knowing not God, are but as instruments in the hand of the workman, serving unconsciously, and perishing in the using; the good, on the other hand, serve consciously, and in serving become more perfect.

This, Sir, is all I can now contribute to answering your question, and I have no higher wish than that it may satisfy you. But in case you still find any difficulty, I beg you to let me know of that also, to see if I may be able to remove it. You have nothing to fear on your side, but so long as you are not satisfied, I like nothing better than to be informed of your reasons, so that finally the truth may appear. I could have wished to write in the tongue in which I have been brought up. I should, perhaps, have been able to express my thoughts better. But be pleased to take it as it is, amend the mistakes yourself, and believe me,

Your sincere friend and servant.

Long Orchard, near Amsterdam, Jan. 5, 1665

20 (33). Blyenbergh to Spinoza, January 16, 1665 (summary only)

[ I have two rules in my philosophic inquiries; 1. Conformity to reason; 2. conformity to Scripture. I consider the second the most important. Examining your letter by the first, I observe that your identification of God's creative power with his preservative power seems to involve, either that evil does not exist, or else that God brings about evil. If evil be only a term relative to our imperfect knowledge, how do you explain the state of a man who falls from a state of grace into sin? If evil be a negation, how can we have the power to sin ? If God causes an evil act, he must cause the evil as well as the act. You say that every man can only act, as he, in fact does act. This removes all distinction between the good and the wicked. Both, according to you, are perfect. You remove all the sanctions of virtue and reduce us to automata. Your doctrine, that strictly speaking, we cannot sin against God, is a hard saying.

The rest of the letter is taken up with an examination of Spinoza's arguments in respect to their conformity to Scripture.

Dordrecht, 16 Jan., 1665. ]

21 (34). Spinoza to Blyenbergh, January 28, 1665

Friend and Sir,

When I read your first letter, I thought that our opinions almost coincided. But from the second, which was delivered to me on the 21st of this month, I see that the matter stands far otherwise, for I perceive that we disagree, not only in remote inferences from first principles, but also in first principles themselves; so that I can hardly think that we can derive any mutual instruction from further correspondence. I see that no proof, though it be by the laws of proof most sound, has any weight with you, unless it agrees with the explanation, which either you yourself, or other theologians known to you, attribute to Holy Scripture. However, if you are convinced that God speaks more clearly and effectually through Holy Scripture than through the natural understanding, which He also has bestowed upon us, and with His divine wisdom keeps continually stable and uncorrupted, you have valid reasons for making your understanding bow before the opinions which you attribute to Holy Scripture; I myself could adopt no different course. For my own part, as I confess plainly, and without circuml;ocution, that I do not understand the Scriptures, though I have spent some years upon them, and also as I feel that when I have obtained a firm proof, I cannot fall into a state of doubt concerning it, I acquiesce entirely in what is commended to me by my understanding, without any suspicion that I am being deceived in the matter, or that Holy Scripture, though I do not search, could gainsay it: for truth is not at variance with truth, as I have already clearly shown in my appendix to The Principles of Cartesian Philosophy (I cannot give the precise reference, for I have not the book with me here in the country). But if in any instance I found that a result obtained through my natural understanding was false, I should reckon myself fortunate, for I enjoy life, and try to spend it not in sorrow and sighing, but in peace, joy, and cheerfulness, ascending from time to time a step higher. Meanwhile I know (and this knowledge gives me the highest contentment and peace of mind), that all things come to pass by the power and unchangeable decree of a Being supremely perfect.

To return to your letter, I owe you many and sincere thanks for having confided to me your philosophical opinions; but for the doctrines, which you attribute to me, and seek to infer from my letter, I return you no thanks at at all. What ground, I should like to know, has my letter afforded you for ascribing to me the opinions; that men are like beasts, that they die and perish after the manner of beasts, that our actions are displeasing to God, etc.? Perhaps we are most of all at variance on this third point. You think, as far as I can judge, that God takes pleasure in our actions, as though He were a man, who has attained his object, when things fall out as he desired. For my part, have I not said plainly enough, that the good worship God, that in continually serving Him they become more perfect, and that they love God? Is this, I ask, likening them to beasts, or saying that they perish like beasts, or that their actions are displeasing to God? If you had read my letter with more attention, you would have clearly perceived, that our whole dissension lies in the following alternative:-Either the perfections which the good receive are imparted to them by God in His capacity of God, that is absolutely without any human qualities being ascribed to Him-this is what I believe; or else such perfections are imparted by God as a judge, which is what you maintain. For this reason you defend the wicked, saying that they carry out God's decrees as far as in them lies, and therefore serve God no less than the good. But if my doctrine be accepted, this consequence by no means follows; I do not bring in the idea of God as a judge, and, therefore, I estimate an action by its intrinsic merits, not be the powers of its performer; the recompense which follows the action follows from it as necessarily as from the nature of a triangle it follows, that the three angles are equal to two right angles. This may be understood by everyone, who reflects on the fact, that our highest blessedness consists in love towards God, and that such love flows naturally from the knowledge of God, which is so strenuously enjoined on us. The question may very easily be proved in general terms, if we take notice of the nature of God's decrees, as explained in my appendix. However, I confess that all those, who confuse the divine nature with human nature, are gravely hindered from understanding it.

I had intended to end my letter at this point, lest I should prove troublesome to you in these questions, the discussion of which (as I discover from the extremely pious postscript added to your letter) serves you as a pastime and a jest, but for no serious use. However, that I may not summarily deny your request, I will proceed to explain further the words privation and negation, and briefly point out what is necessary for the elucidation of my former letter.

I say then, first, that privation is not the act of depriving, but simply and merely a state of want, which is in itself nothing: it is a mere entity of the reason, a mode of thought framed in comparing one thing with another. We say, for example, that a blind man is deprived of sight, because we readily imagine him as seeing, or else because we compare him with others who can see, or compare his present condition with his past condition when he could see; when we regard the man in this way, comparing his nature either with the nature of others or with his own past nature, we affirm that sight belongs to his nature, and therefore assert that he has been deprived of it. But when we are considering the nature and decree of God, we cannot affirm privation of sight in the case of the aforesaid man any more than in the case of a stone; for at the actual time sight lies no more within the scope of the man than of the stone; since there belongs to man and forms part of his nature only that which is granted to him by the understanding and will of God. Hence it follows that God is no more the cause of a blind man not seeing, than he is of a stone not seeing. Not seeing is a pure negation. So also, when we consider the case of a man who is led by lustful desires, we compare his present desires with those which exist in the good, or which existed in himself at some other time; we then assert that he is deprived of the better desires, because we conceive that virtuous desires lie within the scope of his nature. This we cannot do, if we consider the nature and decree of God. For, from this point of view, virtuous desires lie at that time no more within the scope of the nature of the lustful man, than within the scope of the nature of the devil or a stone. Hence, from the latter standpoint the virtuous desire is not a privation but a negation.

Thus privation is nothing else than denying of a thing something, which we think belongs to its nature; negation is denying of a thing something, which we do not think belongs to its nature.

We may now see, how Adam's desire for earthly things was evil from our standpoint, but not from God's. Although God knew both the present and the past state of Adam, He did not, therefore, regard Adam as deprived of his past state, that is, He did not regard Adam's past state as within the scope of Adam's present nature. Otherwise God would have apprehended something contrary to His own will, that is, contrary to His own understanding. If you quite grasp my meaning here and at the same time remember, that I do not grant to the mind the same freedom as Descartes does -L[ewis] M[eyer] bears witness to this in his preface to my book - you will perceive, that there is not the smallest contradiction in what I have said. But I see that I should have done far better to have answered you in my first letter with the words of Descartes, to the effect that we cannot know how our freedom and its consequences agree with the foreknowledge and freedom of God (see several passages in my appendix), that, therefore, we can discover no contradiction between creation by God and our freedom, because we cannot understand how God created the universe, nor (what is the same thing) how He preserves it. I thought that you had read the preface, and that by not giving you my real opinions in reply, I should sin against those duties of friendship which I cordially offered you. But this is of no consequence.

Still, as I see that you have not hitherto thoroughly grasped Descartes' meaning, I will call your attention to the two following points. First, that neither Descartes nor I have ever said, that it appertains to our nature to confine the will within the limits of the understanding; we have only said, that God has endowed us with a determined understanding and an undetermined will, so that we know not the object for which He has created us. Further, that an undetermined or perfect will of this kind not only makes us more perfect, but also, as I will presently show you, is extremely necessary for us.

Secondly: that our freedom is not placed in a certain contingency nor in a certain indifference, but in the method of affirmation or denial; so that, in proportion as we are less indifferent in affirmation or denial, so are we more free. For instance, if the nature of God be known to us, it follows as necessarily from our nature to affirm God exists, as from the nature of a triangle it follows, that the three angles are equal to two right angles; we are never more free, than when we affirm a thing in this way. As this necessity is nothing else but the decree of God (as I have clearly shown in my appendix), we may hence, after a fashion, understand how we act freely and are the cause of our action, though all the time we are acting necessarily and according to the decree of God. This, I repeat, we may, after a fashion, understand, whenever we affirm something, which we clearly and distinctly perceive, but when we assert something which we do not clearly and distinctly understand, in other words, when we allow our will to pass beyond the limits of our understanding, we no longer perceive the necessity nor the decree of God, we can only see our freedom, which is always involved in our will; in which respect only our actions are called good or evil. If we then try to reconcile our freedom with God's decree and continuous creation, we confuse that which we clearly and distinctly understand with that which we do not perceive, and, therefore, our attempt is vain. It is, therefore, sufficient for us to know that we are free, and that we can be so notwithstanding God's decree, and further that we are the cause of evil, because an act can only be called evil in relation to our freedom. I have said thus much for Descartes in order to show that, in the question we are considering, his words exhibit no contradiction.

I will now turn to what concerns myself, and will first briefly call attention to the advantage arising from my opinion, inasmuch as, according to it, our understanding offers our mind and body to God freed from all superstition. Nor do I deny that prayer is extremely useful to us. For my understanding is too small to determine all the means, whereby God leads men to the love of Himself, that is, to salvation. So far is my opinion from being hurtful, that it offers to those, who are not taken up with prejudices and childish superstitions, the only means for arriving at the highest stage of blessedness.

When you say that, by making men so dependent on God, I reduce them to the likeness of the elements, plants or stones, you sufficiently show that you have thoroughly misunderstood my meaning, and have confused things which regard the understanding with things which regard the imagination. If by your intellect only you had perceived what dependence on God means, you certainly would not think that things, in so far as they depend on God, are dead, corporeal, and imperfect (who ever dared to speak so meanly of the Supremely Perfect Being?); on the contrary, you would understand that for the very reason that they depend on God they are perfect; so that this dependence and necessary operation may best be understood as God's decree, by considering, not stocks and plants, but the most reasonable and perfect creatures. This sufficiently appears from my second observation on the meaning of Descartes, which you ought to have looked to.

I cannot refrain from expressing my extreme astonishment at your remarking, that if God does not punish wrongdoing (that is, as a judge does, with a punishment not intrinsically connected with the offense, for our whole difference lies in this), what reason prevents me from rushing headlong into every kind of wickedness? Assuredly he, who is only kept from vice by the fear of punishment (which I do not think of you), is in no wise acted on by love, and by no means embraces virtue. For my own part, I avoid or endeavour to avoid vice, because it is at direct variance with my proper nature and would lead me astray from the knowledge and love of God.

Again, if you had reflected a little on human nature and the nature of God's decree (as explained in my appendix), and perceived, and known by this time, how a consequence should be deduced from its premises, before a conclusion is arrived at; you would not so rashly have stated that my opinion makes us like stocks, etc.: nor would you have ascribed to me the many absurdities you conjure up.

As to the two points which you say, before passing on to your second rule, that you cannot understand; I answer, that the first may be solved through Descartes, who says that in observing your own nature you feel that you can suspend your judgment. If you say that you do not feel, that you have at present sufficient force to keep your judgment suspended, this would appear to Descartes to be the same as saying that we cannot at present see, that so long as we exist we shall always be thinking things, or retain the nature of thinking things; in fact it would imply a contradiction.

As your second difficulty, I say with Descartes, that if we cannot extend our will beyond the bounds of our extremely limited understanding, we shall be most wretched -it will not be in our power to eat even a crust of bread, or to walk a step, or to go on living, for all things are uncertain and full of peril.

I now pass on to your second rule, and assert that I believe, though I do not ascribe to Scripture that sort of truth which you think you find in it, I nevertheless assign to it as great if not greater authority than you do. I am far more careful than others not to ascribe to Scripture any childish and absurd doctrines, a precaution which demands either a thorough acquaintance with philosophy or the possession of divine revelations. Hence I pay very little attention to the glosses put upon Scripture by ordinary theologians, especially those of the kind who always interpret Scripture according to the literal and outward meaning: I have never, except among the Socinians, found any theologian stupid enough to ignore that Holy Scripture very often speaks in human fashion of God and expresses its meaning in parables; as for the contradiction which you vainly (in my opinion) endeavour to show, I think you attach to the word parable a meaning different from that usually given. For who ever heard, that a man, who expressed his opinions in parables, had therefore taken leave of his senses? When Micaiah said to King Ahab, that he had seen God sitting on a throne, with the armies of heaven standing on the right hand and the left, and that God asked His angels which of them would deceive Ahab, this was assuredly a parable employed by the prophet on that occasion (which was not fitted for the inculcation of sublime theological doctrines), as sufficiently setting forth the message he had to deliver in the name of God. We cannot say that he had in anywise taken leave of his senses. So also the other prophets of God made manifest God's commands to the people in this fashion as being the best adapted, though not expressly enjoined by God, for leading the people to the primary object of Scripture, which, as Christ Himself says, is to bid men love God above all things, and their neighbour as themselves. Sublime speculations have, in my opinion, no bearing on Scripture. As far as I am concerned I have never learnt or been able to learn any of God's eternal attributes from Holy Scripture.

As to your fifth argument (that the prophets thus made manifest the word of God, since truth is not at variance with truth), it merely amounts, for those who understand the method of proof, to asking me to prove, that Scripture, as it is, is the true revealed word of God. The mathematical proof of this proposition could only be attained by divine revelation. I, therefore, expressed myself as follows: I believe, but I do not mathematically know, that all things revealed by God to the prophets, etc. Inasmuch as I firmly believe but do not mathematically know, that the prophets were the most trusted counsellors and faithful ambassadors of God. So that in all I have written there is no contradiction, though several such may be found among holders of the opposite opinion.

The rest of your letter (to wit the passage where you say, Lastly, the supremely perfect Being knew beforehand, etc; and again, your objections to the illustration from poison, and lastly, the whole of what you say of the appendix and what follows) seems to me beside the question.

As regards Lewis Meyer's preface, the points which were still left to be proved by Descartes before establishing his demonstration of free will, are certainly there set forth; it is added that I hold a contrary opinion, my reasons for doing so being given. I shall, perhaps, in due time give further explanations. For the present I have no such intention.

I have never thought about the work on Descartes nor given any further heed to it, since it has been translated into Dutch. I have my reasons, though it would be tedious to enumerate them here. So nothing remains for me but to subscribe myself, etc.

22 (35). Blyenbergh to Spinoza, February 16, 1665 (summary only)

[ The tone of your last letter is very different from that of your first. If our essence is equivalent to our state at a given time, we are as perfect when sinning as when virtuous: God would wish for vice as much as virtue. Both the virtuous and the vicious execute God's will----- What is the difference between them? You say some actions are more perfect than others; wherein does this perfection consist? If a mind existed so framed, that vice was in agreement with the proper nature, why should such a mind prefer good to evil? If God makes us all that we are, how can we "go astray "? Can rational substances depend on God in any way except lifelessly ?

What is the difference between a rational being's depending on God, and an irrational being's? If we have no free will, are not our actions God's actions, and our will God's will? I could ask several more questions, but do not venture.

P.S. In my hurry I forgot to insert this question: Whether we cannot by forsight avert what would otherwise happen to us?

23 (36). Spinoza to Blyenbergh, March 13, 1665

Friend and Sir,

I have received two letters from you this week; the second, dated 9th March, only served to inform me of the first written on February 19th, and sent to me at Schiedam. In the former I see that you complain of my saying, that demonstration carried no weight with you, as though I had spoken of my own arguments, which had failed to convince you. Such was far from my intention. I was referring to your own words, which ran as follows: - And if after long investigation it comes to pass, that my natural knowledge appears either to be at variance with the word (of Scripture), or not sufficiently well, etc.; the word has so great authority with me, that I would rather doubt of the conceptions, which I think I clearly perceive, etc. You see I merely repeat in brief your own phrase, so that I cannot think you have any cause for anger against me, especially as I merely quoted in order to show the great difference between our standpoints.

Again, as you wrote at the end of your letter that your only hope and wish is to continue in faith and hope, and that all else, which we may become convinced of through our natural faculties, is indifferent to you; I reflected, as I still continue to do, that my letters could be of no use to you, and that I should best consult my own interests by ceasing to neglect my pursuits (which I am compelled while writing to you to interrupt) for the sake of things which could bring no possible benefit. Nor is this contrary to the spirit of my former letter, for in that I looked upon you as simply a philosopher, who (like not a few who call themselves Christians) possesses no touchstone of truth save his natural understanding, and not as a theologian. However, you have taught me to know better, and have also shown me that the foundation, on which I was minded to build up our friendship, has not, as I imagined, been laid.

As for the rest, such are the general accompaniments of controversy, so that I would not on that account transgress the limits of courtesy: I will, therefore, pass over in your second letter, and in this, these and similar expressions, as though they had never been observed. So much for your taking offense; to show you that I have given you no just cause, and, also, that I am quite willing to brook contradiction. I now turn a second time to answering your objections.

I maintain, in the first place, that God is absolutely and really the cause of all things which have essence, whatsoever they may be. If you can demonstrate that evil, error, crime, etc., have any positive existence, which expresses essence, I will fully grant you that God is the cause of crime, evil, error, etc., I believe myself to have sufficiently shown, that that which constitutes the reality of evil, error, crime, etc., does not consist in anything, which expresses essence, and therefore we cannot say that God is its cause. For instance, Nero's matricide, in so far as it comprehended anything positive, was not a crime; the same outward act was perpetrated, and the same matricidal intention was entertained by Orestes; who, nevertheless, is not blamed-at any rate, not so much as Nero. Wherein, then, did Nero's crime consist? In nothing else, but that by his deed he showed himself to be ungrateful, unmerciful, and disobedient. Certainly none of these qualities express aught of essence, therefore God was not the cause of them, though He was the cause of Nero's act and intention.

Further, I would have you observe, that, while we speak philosophically, we ought not to employ theological phrases. For, since theology frequently, and not unwisely, represents God as a perfect man, it is often expedient in theology to say, that God desires a given thing, that He is angry at the actions of the wicked, and delights in those of the good. But in philosophy, when we clearly perceive that the attributes which make men perfect can as ill be ascribed and assigned to God, as the attributes which go to make perfect the elephant and the ass can be ascribed to man; here I say these and similar phrases have no place, nor can we employ them without causing extreme confusion in our conceptions. Hence, in the language of philosophy, it cannot be said that God desires anything of any man, or that anything is displeasing or pleasing to Him: all these are human qualities and have no place in God.

I would have it observed, that although the actions of the good (that is of those who have a clear idea of God, whereby all their actions and their thoughts are determined) and of the wicked (that is of those who do not possess the idea of God, but only the ideas of earthly things, whereby their actions and thoughts are determined), and, in fact, of all things that are, necessarily flow from God's eternal laws and decrees; yet they do not differ from one another in degree only, but also in essence. A mouse no less than an angel, and sorrow no less than joy depend on God; yet a mouse is not a kind of angel, neither is sorrow a kind of joy. I think I have thus answered your objections, if I rightly understand them, for I sometimes doubt, whether the conclusions which you deduce are not foreign to the proposition you are undertaking to prove.

However, this will appear more clearly, if I answer the questions you proposed on these principles. First, Whether murder is as acceptable to God as alms-giving? Secondly, Whether stealing is as good in relation to God as honesty? Thirdly and lastly, Whether if there be a mind so framed, that it would agree with, rather than be repugnant to its proper nature, to give way to lust, and to commit crimes, whether, I repeat, there can be any reason given, why such a mind should do good and eschew evil?

To your first question, I answer, that I do not know, speaking as a philosopher, what you mean by the words acceptable to God. If you ask, whether God does not hate the wicked, and love the good? whether God does not regard the former with dislike, and the latter with favour? I answer, No. If the meaning of your question is: Are murderers and almsgivers equally good and perfect? my answer is again in the negative. To your second question, I reply: If, by good in relation to God, you mean that the honest man confers a favour on God, and the thief does Him an injury, I answer that neither the honest man nor the thief can cause God any pleasure or displeasure. If you mean to ask, whether the actions of each, in so far as they posssess reality, and are caused by God, are equally perfect? I reply that, if we merely regard the actions and the manner of their execution, both may be equally perfect. If you, therefore, inquire whether the thief and the honest man are equally perfect and blessed? I answer, No. For, by an honest man, I mean one who always desires, that everyone should possess that which is his. This desire, as I prove in my Ethics (as yet unpublished), necessarily derives its origin in the pious from the clear knowledge which they possess, of God and of themselves. As a thief has no desire of the kind, he is necessarily without the knowledge of God and of himself-in other words, without the chief element of our blessedness. If you further ask, What causes you to perform a given action, which I call virtuous, rather than another? I reply, that I cannot know which method, out of the infinite methods at His disposal, God employs to determine you to the said action. It may be, that God has impressed you with a clear idea of Himself, so that you forget the world for love of Him, and love your fellow-men as yourself; it is plain that such a disposition is at variance with those dispositions which are called bad, and, therefore, could not co-exist with them in the same man.

However, this is not the place to expound all the foundations of my Ethics, or to prove all that I have advanced; I am now only concerned in answering your questions, and defending myself against them.

Lastly, as to your third question, it assumes a contradiction, and seems to me to be, as though one asked: If it agreed better with a man's nature that he should hang himself, could any reasons be given for his not hanging himself? Can such a nature possibly exist? If so, I maintain (whether I do or do not grant free will), that such an one, if he sees that he can live more conveniently on the gallows than sitting at his own table, would act most foolishly, if he did not hang himself. So anyone who clearly saw that, by committing crimes, he would enjoy a really more perfect and better life and existence, than he could attain by the practice of virtue, would be foolish if he did not act on his convictions. For, with such a perverse human nature as his, crime would become virtue.

As to the other question, which you add in your postscript, seeing that one might ask a hundred such in an hour, without arriving at a conclusion about any, and seeing that you yourself do not press for an answer, I will send none.

I will now only subscribe myself, etc.

27 (38). Spinoza to Blyenbergh, June 3, 1665

Friend and Sir,

When your letter, dated 27th March, was delivered to me, I was just starting for Amsterdam. I, therefore, after reading half of it, left it at home, to be answered on my return: for I thought it dealt only with questions raised in our first controversy. However, a second perusal showed me, that it embraced a far wider subject, and not only asked me for a proof of what, in my preface to Principles of Cartesian Philosophy, I wrote (with the object of merely stating, without proving or urging my opinion), but also requested me to impart a great portion of my Ethics, which, as everyone knows, ought to be based on physics and metaphysics. For this reason, I have been unable to allow myself to satisfy your demands. I wished to await an opportunity for begging you, in a most friendly way, by word of mouth, to withdraw your request, for giving you my reasons for refusal, and for showing that your inquiries do not promote the solution of our first controversy, but, on the contrary, are for the most part entirely dependent on its previous settlement. So far are they not essential to the understanding of my doctrine concerning necessity, that they cannot be apprehended, unless the latter question is understood first. However, before such an opportunity offered, a second letter reached me this week, appearing to convey a certain sense of displeasure at my delay. Necessity, therefore, has compelled me to write you these few words, to acquaint you more fully with my proposal and decision. I hope that, when the facts of the case are before you, you will, of your own accord, desist from your request, and will still remain kindly disposed towards me. I, for my part, will, in all things, according to my power, prove myself your, etc.

28 (-). Spinoza to Boumster*, June, 1665

Dear Friend,

I do not know whether you have quite forgotten me; but there are many circumstances which lead me to suspect it. First, when I was setting out on my journey, I wished to bid you good- bye; and, after your own invitation, thinking I should certainly find you at home, heard that you had gone to the Hague. I return to Voorburg, nothing doubting but that you would at least have visited me in passing; but you, forsooth, without greeting your friend, went back home. Three weeks have I waited, without getting sight of a letter from you. If you wish this opinion of mine to be changed, you may easily change it by writing; and you can, at the same time, point out a means of entering into a correspondence, as we once talked of doing at your house.

Meanwhile, I should like to ask you, nay I do beg and entreat you, by our friendship, to apply yourself to some serious work with real study, and to devote the chief part of your life to the cultivation of your understanding and your soul. Now, while there is time, and before you complain of having let time and, indeed, your own self slip by. Further, in order to set our correspondence on foot, and to give you courage to write to me more freely, I would have you know that I have long thought, and, indeed, been almost certain, that you are somewhat too diffident of your own abilities, and that you are afraid of advancing some question or proposal unworthy of a man of learning. It does not become me to praise you, and expatiate on your talents to your face; but, if you are afraid that I shall show your letters to others, who will laugh at you, I give you my word of honour, that I will religiously keep them, and will show them to no mortal without your leave. On these conditions, you may enter on a correspondence, unless you doubt of my good faith, which I do not in the least believe. I want to hear your opinion on this in your first letter; and you may, at the same time, send me the conserve of red roses, though I am now much better.

After my journey, I was once bled; but the fever did not cease, though I was somewhat more active than before the bleeding, owing, I think, to the change of air; but I was two or three times laid up with a tertian. This, however, by good diet, I have at length driven away, and sent about its business. Where it has gone, I know not; but I am taking care it does not return here.

As regards the third part of my philosophy, I will shortly send it you, if you wish to be its transmitter, or to our friend De Vries; and, although I had settled not to send any of it, till it was finished, yet, as it takes longer than Ithought, I am unwilling to keep you waiting. I will send up to the eightieth proposition, or thereabouts.

Of English affairs I hear a good deal, but nothing for certain. The people continue to be apprehensive, and can see no reason, why the fleet should not be despatched; but the matter does not yet seem to be set on foot. I am afraid our rulers want to be overwise and prudent; but the event will show what they intend, and what they will attempt. May the gods turn it all to good. I want to know, what our people think, where you are, and what they know for certain; but, above all things, I want you to believe me, etc.

32 (15). Spinoza to Oldenburg, November 20, 1665

Distinguished Sir,

For the encouragement to pursue my speculations given me by yourself and the distinguished R. Boyle, I return you my best thanks. I proceed as far as my slender abilities will allow me, with full confidence in your aid and kindness. When you ask me my opinion on the question raised concerning our knowledge of the means, whereby each part of nature agrees with its whole, and the manner in which it is associated with the remaining parts, I presume you are asking for the reasons which induce us to believe, that each part of nature agrees with its whole, and is associated with the remaining parts. For as to the means whereby the parts are really associated, and each part agrees with its whole, I told you in my former letter that I am in ignorance. To answer such a question, we should have to know the whole of nature and its several parts. I will therefore endeavour to show the reason, which led me to make the statement; but I will premise that I do not attribute to nature either beauty or deformity, order or confusion. Only in relation to our imagination can things be called beautiful or deformed, ordered or confused.

By the association of parts, then, I merely mean that the laws or nature of one part adapt themselves to the laws or nature of another part, so as to cause the least possible in consistency. As to the whole and the parts, I mean that a given number of things are parts of a whole, in so far as the nature of each of them is adapted to the nature of the rest, so that they all, as far as possible, agree together. On the other hand, in so far as they do not agree, each of them forms, in our mind, a separate idea, and is to that extent considered as a whole, not as a part. For instance, when the parts of lymph, chyle, etc., combine, according to the proportion of the figure and size of each, so as to evidently unite, and form one fluid, the chyle, lymph, etc., considered under this aspect, are part of the blood; but, in so far as we consider the particles of lymph as differing in figure and size from the particles of chyle, we shall consider each of the two as a whole, not as a part.

Let us imagine, with your permission, a little worm, living in the blood, able to distinguish by sight the particles of blood, lymph, etc., and to reflect on the manner in which each particle, on meeting with another particle, either is repulsed, or communicates a portion of its own motion. This little worm would live in the blood, in the same way, as we live in a part of the universe, and would consider each particle of blood, not as a part, but as a whole. He would be unable to determine, how all the parts are modified by the general nature of blood, and are compelled by it to adapt themselves, so as to stand in a fixed relation to one another. For, if we imagine that there are no causes external to the blood, which could communicate fresh movements to it, nor any space beyond the blood, nor any bodies whereto the particles of blood could communicate their motion, it is certain that the blood would always remain in the same state, and its particles would undergo no modifications, save those which may be conceived as arising from the relations of motion existing between the lymph, the chyle, etc. The blood would then always have to be considered as a whole, not as a part. But, as there exist, as a matter of fact, very many causes which modify, in a given manner, the nature of the blood, and are, in turn, modified thereby, it follows that other motions and other relations arise in the blood, springing not from the mutual relations of its parts only, but from the mutual relations between the blood as a whole and external causes. Thus the blood comes to be regarded as a part, not as a whole. So much for the whole and the part.

All natural bodies can and ought to be considered in the same way as we have here considered the blood, for an bodies are surrounded by others, and are mutually determined to exist and operate in a fixed and definite proportion while the relations between motion and rest in the sum total of them, that is, in the whole universe, remain unchanged. Hence it follows that each body, in so far as it exists as modified in a particular manner, must be considered as a part of the whole universe, as agreeing with the whole, and associated with the remaining parts. As the nature of the universe is not limited, like the nature of blood, but is absolutely infinite, its parts are by this nature of infinite power infinitely modified, and compelled to undergo infinite variations. But, in respect to substance, I conceive that each part has a more close union with its whole. For, as I said in my first letter, (addressed to you while I was still at Rhijnsburg), substance being infinite in its nature, it follows, as I endeavoured to show, that each part belongs to the nature of substance, and, without it, can neither be nor be conceived.

You see, therefore, how and why I think that the human body is a part of nature. As regards the human mind, I believe that it also is a part of nature; for I maintain that there exists in nature an infinite power of thinking, which, in so far as it is infinite, contains subjectively the whole of nature, and its thoughts proceed in the same manner as nature--that is, in the sphere of ideas. Further, I take the human mind to be identical with this said power, not in so far as it is infinite, and perceives the whole of nature, but in so far as it is finite, and perceives only the human body; in this manner, I maintain that the human mind is a part of an infinite understanding.

But to explain, and accurately prove, all these and kindred questions, would take too long; and I do not think you expect as much of me at present. I am afraid that I may have mistaken your meaning, and given an answer to a different question from that which you asked. Please inform me on this point.

You write in your last letter, that I hinted that nearly all the Cartesian laws of motion are false. What I said was, if I remember rightly, that Huyghens thinks so; I myself do not impeach any of the laws except the sixth, concerning which I think Huyghens is also in error. I asked you at the same time to communicate to me the experiment made according to that hypothesis in your Royal Society; as you have not replied, I infer that you are not at liberty to do so. The abovementioned Huyghens is entirely occupied in polishing lenses. He has fitted up for the purpose a handsome workshop, in which he can also construct moulds. What will be the result I know not, nor, to speak the truth, do I greatly care. Experience has sufficiently taught me, that the free hand is better and more sure than any machine for polishing spherical moulds. I can tell you nothing certain as yet about the success of the clocks or the date of Huyghens' journey to France.

Distinguished Sir,

The demonstration of the unity of God, on the ground that His nature involves necessary existence, which you asked for, and I took note of, I have been prevented by various business from sending to you before. In order to accomplish my purpose, I will premise-

I. That the true definition of anything includes nothing except the simple nature of the thing defined. From this it follows-

II. That no definition can involve or express a multitude or a given number of individuals, inasmuch as it involves and expresses nothing except the nature of the thing as it is in itself. For instance, the definition of a triangle includes nothing beyond the simple nature of a triangle; it does not include any given number of triangles. In like manner, the definition of the mind as a thinking thing, or the definition of God as a perfect Being, includes nothing beyond the natures of the mind and of God, not a given number of minds or gods.

III. That for everything that exists there must necessarily be a positive cause, through which it exists.

IV. This cause may be situate either in the nature and definition of the thing itself (to wit, because existence belongs to its nature or necessarily includes it), or externally to the thing.

From these premisses it follows, that if any given number of individuals exists in nature, there must be one or more causes, which have been able to produce exactly that number of individuals, neither more nor less. If, for instance, there existed in nature twenty men (in order to avoid all confusion, I will assume that these all exist together as primary entities), it is not enough to investigate the cause of human nature in general, in order to account for the existence of these twenty; we must also inquire into the reason, why there exist exactly twenty men, neither more nor less. For (by our third hypothesis) for each man a reason and a cause must be forthcoming, why he should exist. But this cause (by our second and third hypotheses) cannot be contained in the nature of man himself; for the true definition of man does not involve the number of twenty men. Hence (by our fourth hypothesis) the cause for the existence of these twenty men, and consequently for the existence of each of them, must exist externally to them. We may thus absolutely conclude, that all things, which are conceived to exist in the plural number, must necessarily be produced by external causes and not by the force of their own nature. But since (by our second hypothesis) necessary existence appertains to the nature of God, His true definition must necessarily include necessary existence: therefore from His true definition His necessary existence must be inferred. But from His true definition (as I have already demonstrated from our second and third hypotheses) the necessary existence of many gods cannot be inferred. Therefore there only follows the existence of a single God. Which was to be proved.

This, distinguished Sir, has now seemed to me the best method for demonstrating the proposition. I have also proved it differently by means of the distinction between essence and existence; but bearing in mind the object you mentioned to me, I have preferred to send you the demonstration given above. I hope it will satisfy you, and I will await your reply, meanwhile remaining, etc.

35 (40). Spinoza to Hudde**, April 10, 1666

Distinguished Sir,

In your last letter, written on March 30th, you have excellently elucidated the point, which was somewhat obscure to me in your letter of February 10th. As I now know your opinion, I will set forth the state of the question as you conceive it; whether there be only a single Being who subsists by his own sufficiency or force ? I not only affirm this to be so, but also undertake to prove it from the fact, that the nature of such a Being necessarily involves existence; perhaps it may also be readily proved from the understanding of God (as I set forth, Principles of Cartesian Philosophy, I. Prop. i.), or from others of His attributes. Before treating of the subject I will briefly show, as preliminaries, what properties must be possessed by a Being including necessary existence. To wit:-

I. It must be eternal. For if a definite duration be assigned to it, it would beyond that definite duration be conceived as non- existent, or as not involving necessary existence, which would be contrary to its definition.

II. It must be simple, not made up of parts. For parts must in nature and knowledge be prior to the whole they compose: this could not be the case with regard to that which is eternal.

III. It cannot be conceived as determinate, but only as infinite. For, if the nature of the said Being were determinate, and conceived as determinate, that nature would beyond the said limits be conceived as non- existent, which again is contrary to its definition.

IV. It is indivisible. For if it were divisible, it could be divided into parts, either of the same or of different nature. If the latter, it could be destroyed and so not exist, which is contrary to its definition; if the former, each part would in itself include necessary existence, and thus one part could exist without others, and consequently be conceived as so existing. Hence the nature of the Being would be comprehended as finite, which, by what has been said, is contrary to its definition. Thus we see that, in attempting to ascribe to such a Being any imperfection, we straightway fall into contradictions. For, whether the imperfection which we wish to assign to the said Being be situate in any defect, or in limitations possessed by its nature, or in any change which it might, through deficiency of power, undergo from external causes, we are always brought back to the contradiction, that a nature which involves necessary existence, does not exist, or does not necessarily exist. I conclude, therefore-

V. That everything, which includes necessary existence, cannot have in itself any imperfection, but must express pure perfection.

VI. Further, since only from perfection can it come about, that any Being should exist by its own sufficiency and force, it follows that, if we assume a Being to exist by its own nature, but not to express all perfections, we must further suppose that another Being exists, which does comprehend in itself all perfections. For, if the less powerful Being exists by its own sufficiency, how much more must the more powerful so exist?

Lastly, to deal with the question, I affirm that there can only be a single Being, of which the existence belongs to its nature; such a Being which possesses in itself all perfections I will call God. If there be any Being to whose nature existence belongs, such a Being can contain in itself no imperfection, but must (by my fifth premise) express every perfection; therefore, the nature of such a Being seems to belong to God (whose existence we are bound to affirm by Premiss VI.), inasmuch as He has in Himself all perfections and no imperfections. Nor can it exist externally to God. For if, externally to God, there existed one and the same nature involving necessary existence, such nature would be twofold; but this, by what we have just shown, is absurd. Therefore there is nothing save God, but there is a single God, that involves necessary existence, which was to be proved.

Such, distinguished Sir, are the arguments I can now produce for demonstrating this question. I hope I may also demonstrate to you, that I am, etc.

Voorburg, 10 April, 1666.

36 (41). Spinoza to Hudde**, May, 1666

Distinguished Sir,

I have been by one means or another prevented from answering sooner your letter, dated 19th May. As I gather that you suspend your judgment with regard to most of the demonstration I sent you (owing, I believe, to the obscurity you find in it), I will here endeavour to explain its meaning more clearly.

First I enumerated four properties, which a Being existing by its own sufficiency or force must possess. These four, and others like them, I reduced in my fifth observation to one. Further, in order to deduce all things necessary for the demonstration from a single premise, I endeavoured in my sixth observation to demonstrate the existence of God from the given hypothesis; whence, lastly, taking (as you know) nothing beyond the ordinary meaning of the terms, I drew the desired conclusion.

Such, in brief, was my purpose and such my aim. I will now explain the meaning of each step singly, and will first start with the aforesaid four properties.

In the first you find no difficulty, nor is it anything but, as in the case of the second, an axiom. By simple I merely mean not compound, or not made up of parts differing in nature or other parts agreeing in nature. This demonstration is assuredly universal.

The sense of my third observation (that if the Being be thought, it cannot be conceived as limited by thought, but only as infinite, and similarly, if it be extension, it cannot be conceived as limited by extension) you have excellently perceived, though you say you do not perceive the con. elusion; this last is based on the fact, that a contradiction is involved in conceiving under the category of non-existence anything, whose definition includes or (what is the same thing) affirms existence. And since determination implies nothing positive, but only a limitation of the existence of the nature conceived as determinate, it follows that that, of which the definition affirms existence, cannot be conceived as determinate. For instance, if the term extension included necessary existence, it would be alike impossible to conceive extension without existence and existence without extension. If this were established, it would be impossible to conceive determinate extension. For, if it be conceived as determinate, it must be determined by its own nature, that is by extension, and this extension, whereby it is determined, must be conceived under the category of non-existence, which by the hypothesis is obviously a contradiction. In my fourth observation, I merely wished to show, that such a Being could neither be divided into parts of the same nature or parts of a different nature, whether those of a different nature involved necessary existence or not. If, I said, we adopt the second view, the Being would be destroyed; for destruction is merely the resolution of a thing into parts so that none of them expresses the nature of the whole; if we adopt the first view, we should be in contradiction with the first three properties.

In my fifth observation, I merely asserted, that perfection consists in being, and imperfection in the privation of being. I say the privation; for although extension denies of
