"He denied personal immortality, and worshiped reason alone. He appears to have had no sexual life, existed austerely, and sensibly allowed his most important writings, including the "Ethics," only a posthumous publication. As a teacher of reality, he practiced his own wisdom, and was surely one of the most exemplary human beings ever to have lived. He troubles me most by his extraordinary autonomy, all but unique in that Jewish history of which he did not desire to be a participant, in any way whatsoever."
"Leo Strauss (never to be confused with our plague of his disciples' disciples) implicitly manifested a distaste for Spinoza, in surprising contrast to his high regard for Machiavelli. After expending a recent month in constantly rereading Spinoza, I find myself ambivalent toward this grandest of Jewish secular philosophers. (Wittgenstein was uneasily aware of his Jewish lineage, and reticent about it.)"
"The German and English Romantics (Shelley aside) got Spinoza wrong. Reading his superbly cryptic masterwork, the "Ethics," I find myself agreeing with Strauss that Spinoza pragmatically was an Epicurean materialist. As in Epicurus and Lucretius, Spinoza's God is scarcely distinguishable from Nature, and is altogether indifferent to us, even to our intellectual love for him as urged upon us by Spinoza."
"He flew through the nets of Judaism, Calvinism, Aristotelianism and the Cartesian dualism, but nevertheless Descartes was his starting point. Could he have become Spinoza without Descartes? Did he beget himself, as Socrates did, or even as Hobbes largely was self-generated? Spinoza's "Nature or God" is not one of the Cartesian formulations, but Spinoza relies upon a number of Cartesian concepts."
"[Ramin Jahanbegloo's question: Hegel was very much influenced by Spinoza. Don't you think so?] I think Hegel was much more influenced by Aristotle than by Spinoza. As for the influence of Spinoza on Hegel, it exists. But the Spinoza of the eighteenth century is not Spinoza; the Spinoza of Herder, the Spinoza of Goethe, is not Spinoza, nor is the Spinoza of Diderot. In the case of the Germans his world turns into an active pantheism; “Deus sive Natura” turns into a quasi-mystical doctrine, a romantic approach remote from the dry light of Spinoza."
"Leibniz's doctrine is an evolutionary doctrine. It is not the same thing with Spinoza. Spinoza has no sense of change and evolution. He has no sense of history."
"He [Spinoza] believes in authority. And, of course, he believed in freedom of thought and expression, whereas Hobbes does not. There is a book on Spinoza written by an American ex-Marxist, called Spinoza and the Rise of Liberalism, on these lines. But Spinoza is not a theorist in whom I am particularly interested, because he is too rationalistic for me. But the Ethics is a wonderful book, and full of deep insights and noble feeling. It is totally unhistorical: the idea of timeless truths about human beings seems suspect to me."
"I think Spinoza was a complete monist. Unity is good, multiplicity cannot lead you to the truth. His political theory is in some ways like that of Hobbes. From his point of view, in politics you have to govern. In order to govern, a rational person might have to do things which are not strictly honourable. Spinoza is a surprisingly tough-minded political thinker."
"Jacobi, a mystical metaphysician deeply influenced by Hamann, cannot reconcile the demands of the soul and the intellect: 'The light is in my heart: as soon as I try to carry it to my intellect, it goes out.' Spinoza was for him the greatest master since Plato of the rational vision of the universe; but for Jacobi this is death in life: it does not answer the burning questions of the soul whose homelessness in the chilly world of the intellect only self-surrender to faith in a transcendent God will remedy."
"This monograph [George L. Kline's Spinoza in Soviet Philosophy] deals with one of the curiosities of contemporary philosophy. Spinoza is to this day highly regarded in the Soviet Union. The fact that he was a rationalist and, in some sense, an atheist in an age of religious intolerance, naturally endeared him to the Soviet authorities, particularly during their early period of militant atheism. But if these are the attributes which gain favour for thinkers one might have thought that others, Hobbes, for instance, or Gassendi, had rather better claims, as militant materialists not committed to the full-blown a priori rationalism of Spinoza. Spinoza's hitherto secure position in a Soviet Pantheon seems mainly due to the accidental fact that Plekhanov, who, by his superior learning and intellectual gifts, intimidated virtually all other Russian Marxists into some degree of conformity, took Spinoza under his special protection, and firmly laid it down that his notion of men as objects in nature made him the father of French materialism of the eighteenth century; that from his sprang Diderot, Helvétius, d'Holbach, etc. and therefore, in due course, also Feuerbach, Marx and Engels. This thesis, once enunciated, was mechanically repeated by later Russian Marxist historians of thought, none of whom seemed aware either that Diderot's essay on Spinoza is by no means an unqualified eulogy of his views, or of the vast differences between Spinoza's and Newton's universes."
"Every philosopher has two philosophies: his own and Spinoza's."
"My interest in Spinoza dates back a very long time, because although I didn't go to university I read an enormous amount when I was young. And I came across Spinoza quite early on. I sensed something in his writing which fascinated me and helped me to see, to look at life. If one wants to be very simple about it I suppose that fascination, or that secret, has to do with his rejection of the Cartesian division between the physical and the spiritual, between body and soul. Because Spinoza maintained that the two are indivisible and that the body is not a kind of machine, as Descartes suggested."
"[Jérome Skalski's question: Wasn't Spinoza also a thinker of radical democracy? Philosophically, was Althusserian Marxism also a return to Spinoza?] Althusser admired the Spinoza of the Theological-Political Treatise, but that was not the aspect that interested him the most. You are absolutely right to say that Spinoza's thought is a radically democratic thought. This is a dimension that has come to the forefront for a while now, and which has been appropriated by a broad variety of philosophers some of whom effectively come from a Marxist background. However, this was not the aspect or dimension that interested Althusser. Not because he was hostile towards it, but because he fundamentally thought that radical democracy was a transition, an intermediary stage towards the dictatorship of the proletariat. From this point of view, he was a very orthodox Marxist. The dimension that he emphasized in Spinoza concerned the theory of ideology. With Spinoza, there is the first great materialist critique of ideology. Althusser defended a paradoxical thesis. I understand that it forcefully shocked many Marxists at the time but, on the other hand, it was very attractive to certain people among us. This idea was that the concept of ideology was the fundamental aspect of Marx's theoretical revolution: not only the critique of bourgeois ideology, but the critique of ideology in general. To Althusser, this also appeared to be an important point within the debates internal to Communism at the time, in that it was dominated by the ideological complex he called humanism and economism. He thought that the Marxist tradition was weak on the question of ideology and that Marx, even if he possessed the genius to invent the concept, had had a very bad analysis of it. In Spinoza, he found the elements for a materialist theory of ideology that was neither Feuerbachian or Hegelian, and was not attached to a philosophy of history or to the concept of an alienation of man or a human essence. All of this paired very well with what was called Althusser’s scientism, such as it was expressed in the idea of the epistemological break and led to his proximity with structuralism. Althusser quickly criticized these positions in his Elements of Self-Criticism."
"He [Deleuze] said of Spinoza that he was the Christ of philosophy. To do Deleuze full justice, let us say that, of this Christ and his inflexible announcement of salvation by the All — a salvation that promises nothing, a salvation that is always already there — he was truly a most eminent apostle."
"That was in 1656, and Spinoza died in 1677, at the early age of forty-four. Glory had not found him out. His short life—a life of unbroken diligence, kindliness, and purity—was passed in seclusion. But in spite of that seclusion, in spite of the shortness of his career, in spite of the hostility of the dispensers of renown in the 18th century,—of Voltaire's disparagement and Bayle's detraction,—in spite of the repellent form which he has given to his principal work, in spite of the exterior semblance of a rigid dogmatism alien to the most essential tendencies of modern philosophy, in spite, finally, of the immense weight of disfavour cast upon him by the long-repeated charge of atheism, Spinoza's name has silently risen in importance, the man and his work have attracted a steadily increasing notice, and bid fair to become soon what they deserve to become,—in the history of modern philosophy the central point of interest."
"We can conceive of various kinds of democracy. But my intention is not to treat of every kind, but of that only, "wherein all, without exception, who owe allegiance to the laws of the country only, and are further independent and of respectable life, have the right of voting in the supreme council and of filling the offices of the dominion.""
"I pass, at length, to the third and perfectly absolute dominion, which we call democracy."
"All laws which can be broken without any injury to another, are counted but a laughing-stock, and are so far from bridling the desires and lusts of men, that on the contrary they stimulate them."
"He who seeks equality between unequals seeks an absurdity."
"If slavery, barbarism and desolation are to be called peace, men can have no worse misfortune. No doubt there are usually more and sharper quarrels between parents and children, than between masters and slaves ; yet it advances not the art of household management to change a father's right into a right of property, and count children but as slaves. Slavery, then, and not peace, is furthered by handing the whole authority to one man."
"Civitas, cuius subditi metu territi arma non capiunt, potius dicenda est, quod sine bello sit, quam quod pacem habeat. Pax enim non belli privatio, sed virtus est, quae ex animi fortitudine oritur; est namque obsequium constans voluntas id exsequendi, quod ex communi civitatis decreto fieri debet. Illa praeterea civitas, cuius pax a subditorum inertia pendet, qui scilicet veluti pecora ducuntur, ut tantum servire discant, rectius solitudo, quam civitas dici potest."
"Nature offers nothing that can be called this man's rather than another's ; but, under nature, everything belongs to all — that is, they have authority to claim it for themselves. But, under dominion, where it is by common law determined what belongs to this man, and what to that, he is called just who has a constant will to render to every man his own, but he, unjust who strives, on the contrary, to make his own that which belongs to another."
"In the state of nature, wrong-doing is impossible ; or, if anyone does wrong, it is to himself, not to another. For no one by the law of nature is bound to please another, unless he chooses, nor to hold anything to be good or evil, but what he himself, according to his own temperament, pronounces to be so ; and, to speak generally, nothing is forbidden by the law of nature, except what is beyond everyone's power."
"Man can, indeed, act contrarily to the decrees of God, as far as they have been written like laws in the minds of ourselves or the prophets, but against that eternal decree of God, which is written in universal nature, and has regard to the course of nature as a whole, he can do nothing."
"Speaking generally, he holds dominion, to whom are entrusted by common consent affairs of state — such as the laying down, interpretation, and abrogation of laws, the fortification of cities, deciding on war and peace, &c. But if this charge belong to a council, composed of the general multitude, then the dominion is called a democracy; if the council be composed of certain chosen persons, then it is an aristocracy ; and, if, lastly, the care of affairs of state, and, consequently, the dominion rest with one man, then it has the name of monarchy."
"Sedulo curavi, humanas actiones non ridere, non lugere, neque detestari, sed intelligere; atque adeo humanos affectus, ut sunt amor, odium, ira, invidia, gloria, misericordia et reliquae animi commotiones non ut humanae naturae vitia, sed ut proprietates contemplatus sum, quae ad ipsam ita pertinent, ut ad naturam aëris aestus, frigus, tempestas, tonitru et alia huiusmodi, quae, tametsi incommoda sunt, necessaria tamen sunt, certasque habent causas, per quas eorum naturam intelligere conamur, et mens eorum vera contemplatione aeque gaudet, ac earum rerum cognitione, quae sensibus gratae sunt."
"I have resolved to demonstrate by a certain and undoubted course of argument, or to deduce from the very condition of human nature, not what is new and unheard of, but only such things as agree best with practice."
"Affectus, quibus conflictamur, concipiunt philosophi veluti vitia, in quae homines sua culpa labuntur; quos propterea ridere, flere, carpere vel (qui sanctiores videri volunt) detestari solent. Sic ergo se rem divinam facere, et sapientiae culmen attingere credunt, quando humanam naturam, quae nullibi est, multis modis laudare et eam, quae revera est, dictis lacessere norunt. Homines namque non ut sunt, sed ut eosdem esse vellent, concipiunt; unde factum est, ut plerumque pro e t h i c a satyram scripserint, et ut nunquam p o l i t i c a m conceperint, quae possit ad usum revocari; sed quae pro chimaera haberetur, vel quae in Utopia vel in illo poëtarum aureo saeculo, ubi scilicet minime necesse erat, institui potuisset. Cum igitur omnium scientiarum, quae usum habent, tum maxime p o l i t i c e s t h e o r i a ab ipsius p r a x i discrepare creditur, et regendae reipublicae nulli minus idonei aestimantur, quam theoretici seu philosophi."
"Et sane arduum debet esse, quod adeo raro reperitur. Qui enim posset fieri, si salus in promptu esset et sine magno labore reperiri posset, ut ab omnibus fere negligeretur? Sed omnia praeclara tam difficilia, quam rara sunt."
"sub specie aeternitatis"
"Sentimus experimurque, nos aeternos esse."
"Homo liber de nulla re minus, quam de morte cogitat, et ejus sapientia non mortis, sed vitae meditatio est."
"Maxima superbia vel abjectio est maxima sui ignorantia."
"Deus seu Natura"
"Humanam impotentiam in moderandis et coercendis affectibus servitutem voco; homo enim affectibus obnoxius sui juris non est sed fortunæ in cujus potestate ita est ut sæpe coactus sit quanquam meliora sibi videat, deteriora tamen sequi."
"Meum institutum non est verborum significationem sed rerum naturam explicare"
"Hic conatus aliquid agendi et etiam omittendi ea sola de causa ut hominibus placeamus, vocatur ambitio præsertim quando adeo impense vulgo placere conamur ut cum nostro aut alterius damno quædam agamus vel omittamus; alias humanitas appellari solet."
"veritas norma sui et falsi est"
"Ordo et connexio idearum idem est ac ordo et connexio rerum"
"[B]y Natura naturans we must understand what is in itself and is conceived through itself, or such attributes of substance as express an eternal and infinite essence, that is … God, insofar as he is considered as a free cause. But by Natura naturata I understand whatever follows from the necessity of God's nature, or from God's attributes, that is, all the modes of God's attributes insofar as they are considered as things which are in God, and can neither be nor be conceived without God."
"The perfection of a thing does not annul its existence, but, on the contrary, asserts it. Imperfection, on the other hand, does annul it ; therefore we cannot be more certain of the existence of anything, than of the existence of a being absolutely infinite or perfect—that is, of God. For inasmuch as his essence excludes all imperfection, and involves absolute perfection, all cause for doubt concerning his existence is done away, and the utmost certainty on the question is given. This, I think, will be evident to every moderately attentive reader."
"Deus est omnium rerum causa immanens, non vero transiens"
"A definition, if it is to be called perfect, must explain the inmost essence of a thing, and must take care not to substitute for this any of its properties. In order to illustrate my meaning, without taking an example which would seem to show a desire to expose other people's errors, I will choose the case of something abstract, the definition of which is of little moment. Such is a circle. If a circle be defined as a figure, such that all straight lines drawn from the center to the circumference are equal, every one can see that such a definition does not in the least explain the essence of a circle, but solely one of its properties. Though, as I have said, this is of no importance in the case of figures and other abstractions, it is of great importance in the case of physical beings and realities, for the properties of things are not understood so long as their essences are unknown. If the latter be passed over, there is necessarily a perversion of the succession of ideas which should reflect the succession of nature, and we go far astray from our object."
"Sed amor erga rem aeternam et infinitam sola laetitia pascit animum, ipsaque omnis tristitiae est expers; quod valde est desiderandum totisque viribus quaerendum."
"Tota felicitas aut infelicitas in hoc solo sita est; videlicet in qualitate obiecti, cui adhaeremus amore."
"The ordinary surroundings of life which are esteemed by men (as their actions testify) to be the highest good, may be classed under the three heads — Riches, Fame, and the Pleasures of Sense: with these three the mind is so absorbed that it has little power to reflect on any different good."
"After experience had taught me that all the usual surroundings of social life are vain and futile; seeing that none of the objects of my fears contained in themselves anything either good or bad, except in so far as the mind is affected by them, I finally resolved to inquire whether there might be some real good having power to communicate itself, which would affect the mind singly, to the exclusion of all else: whether, in fact, there might be anything of which the discovery and attainment would enable me to enjoy continuous, supreme, and unending happiness."
"All the better; they do not force me to do anything that I would not have done of my own accord if I did not dread scandal. But since they want it that way, I enter gladly on the path that is opened to me, with the consolation that my departure will be more innocent than was the exodus of the early Hebrews from Egypt."
"Of all the things that are beyond my power, I value nothing more highly than to be allowed the honor of entering into bonds of friendship with people who sincerely love truth. For, of things beyond our power, I believe there is nothing in the world which we can love with tranquility except such men."
"Nature is satisfied with little; and if she is, I am also."
