"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."
"You seem to wish to employ reason, and ask me, "How I know that my philosophy is the best among all that have ever been taught in the world, or are being taught, or ever will be taught?" a question which I might with much greater right ask you ; for I do not presume that I have found the best philosophy, I know that I understand the true philosophy. If you ask in what way I know it, I answer: In the same way as you know that the three angles of a triangle are equal to two right angles: that this is sufficient, will be denied by no one whose brain is sound, and who does not go dreaming of evil spirits inspiring us with false ideas like the true. For the truth is the index of itself and of what is false. But you, who presume that you have at last found the best religion, or rather the best men, on whom you have pinned your credulity, you, "who know that they are the best among all who have taught, do now teach, or shall in future teach other religions. Have you examined all religions, ancient as well as modern, taught here and in India and everywhere throughout the world? And, if you, have duly examined them, how do you know that you have chosen the best" since you can give no reason for the faith that is in you? But you will say, that you acquiesce in the inward testimony of the Spirit of God, while the rest of mankind are ensnared and deceived by the prince of evil spirits. But all those outside the pale of the Romish Church can with equal right proclaim of their own creed what you proclaim of yours. As to what you add of the common consent of myriads of men and the uninterrupted ecclesiastical succession, this is the very catch-word of the Pharisees. They with no less confidence than the devotees of Rome bring forward their myriad witnesses, who as pertinaciously as the Roman witnesses repeat what they have heard, as though it were their personal experience. Further, they carry back their line to Adam. They boast with equal arrogance, that their Church has continued to this day unmoved and unimpaired in spite of the hatred of Christians and heathen. They more than any other sect are supported by antiquity. They exclaim with one voice, that they have received their traditions from God himself, and that they alone preserve the word of God, both written and unwritten. That all heresies have issued from them, and that they have remained constant through thousands of years under no constraint of temporal dominion, but by the sole efficacy of their superstition, no one can deny. The miracles they tell of would tire a thousand tongues. But their chief boast is that they count a far greater number of martyrs than any other nation, a number which is daily increased by those who suffer with singular constancy for the faith they profess; nor is their boasting false. I myself knew among others of a certain Judah called the faithful, who in the midst of the flames, when he was already thought to be dead, lifted his voice to sing the hymn beginning, "To thee, o God, I offer up my soul", and so singing perished."
"I do not think it necessary for salvation to know Christ according to the flesh : but with regard to the Eternal Son of God, that is the Eternal Wisdom of God, which has manifested itself in all things and especially in the human mind, and above all in Christ Jesus, the case is far otherwise. For without this no one can come to a state of blessedness, inasmuch as it alone teaches, what is true or false, good or evil. And, inasmuch as this wisdom was made especially manifest through Jesus Christ, as I have said, his disciples preached it, in so far as it was revealed to them through him, and thus showed that they could rejoice in that spirit of Christ more than the rest of mankind. The doctrines added by certain churches, such as that God took upon himself human nature, I have expressly said that I do not understand; in fact, to speak the truth, they seem to me no less absurd than would a statement, that a circle had taken upon itself the nature of a square. This I think will be sufficient explanation of my opinions concerning the three points mentioned. Whether it will be satisfactory to Christians you will know better than I."
"I make this chief distinction between religion and superstition, that the latter is founded on ignorance, the former on knowledge; this, I take it, is the reason why Christians are distinguished from the rest of the world, not by faith, nor by charity, nor by the other fruits of the Holy Spirit, but solely by their opinions, inasmuch as they defend their cause, like everyone else, by miracles, that is by ignorance, which is the source of all malice; thus they turn a faith, which may be true, into superstition."
"My opinion concerning God differs widely from that which is ordinarily defended by modern Christians. For I hold that God is of all things the cause immanent, as the phrase is, not transient. I say that all things are in God and move in God, thus agreeing with Paul, and, perhaps, with all the ancient philosophers, though the phraseology may be different ; I will even venture to affirm that I agree with all the ancient Hebrews, in so far as one may judge from their traditions, though these are in many ways corrupted. The supposition of some, that I endeavour to prove in the Tractatus Theologico-Politicus the unity of God and Nature (meaning by the latter a certain mass or corporeal matter), is wholly erroneous. As regards miracles, I am of opinion that the revelation of God can only be established by the wisdom of the doctrine, not by miracles, or in other words by ignorance."
"I had hoped that out of so many stories you would at least have produced one or two, which could hardly be questioned, and which would clearly show that ghosts or spectres exist. The case you relate... seems to me laughable. In like manner it would be tedious here to examine all the stories of people, who have written on these trifles. To be brief, I cite the instance of Julius Caesar, who, as Suetonius testifies, laughed at such things and yet was happy. ...And so should all who reflect on the human imagination, and the effects of the emotions, laugh at such notions; whatever Lavater and others, who have gone dreaming with him in the matter, may produce to the contrary."
"If I had as clear an idea of ghosts, as I have of a triangle or a circle, I should not in the least hesitate to affirm that they had been created by God; but as the idea I possess of them is just like the ideas, which my imagination forms of harpies, gryphons, hydras, &c., I cannot consider them as anything but dreams, which differ from God as totally as that which is not differs from that which is."
"This I know, that between finite and infinite there is no comparison; so that the difference between God and the greatest and most excellent created thing is no less than the difference between God and the least created thing."
