"It is well known that Marx was familiar with Spinoza; indeed, he hand-copied whole passages of Spinoza's Tractatus Theologico-Politicus into his notebooks. Less clear is the significance of this fact, and the extent of Spinoza's influence on Marx's thought."

"I believe we can guess at the first time Einstein read Baruch Spinoza's Ethics (Ethica Ordinae Geometrico Demonstrata), a system constructed on the Euclidean model of deductions from propositions. Soon after getting his first real job at the patent office, Einstein joined with two friends to form a discussion circle, meeting once or twice a week in what they called, with gallows humor, the Akademie Olympia. We know the list of books they read and discussed. High among them, reportedly at Einstein's suggestion, was Spinoza's Ethics, which he read afterwards several times more. Even when his sister Maja joined him in Princeton in later life and was confined to bed by an illness, he thought that reading a good book to her would help, and chose Spinoza's Ethics for that purpose. By that time Spinoza's work and life had long been important to Einstein. He had written an introduction to a biography of Spinoza (by his son-in-law, Rudolf Kayser, 1946); he had contributed to the Spinoza Dictionary (1951); he had referred to Spinoza in many of his letters; and he even had composed a poem in Spinoza's honor. He admired Spinoza for his independence of mind, his deterministic philosophical outlook, his skepticism about organized religion and orthodoxy – which had resulted in his excommunication from his synagogue in 1656 – and even for his ascetic preference, which compelled him to remain in poverty and solitude to live in a sort of spiritual ecstasy, instead of accepting a professorship at the University of Heidelberg."

"I assert, that the doctrine of the immateriality, simplicity, and indivisibility of a thinking substance is a true atheism, and will serve to justify all those sentiments, for which Spinoza is so universally infamous. From this topic, I hope at least to reap one advantage, that my adversaries will not have any pretext to render the present doctrine odious by their declamations, when they see that they can be so easily retorted on them."

"The fundamental principle of the atheism of Spinoza is the doctrine of the simplicity of the universe, and the unity of that substance, in which he supposes both thought and matter to inhere. There is only one substance, says he, in the world; and that substance is perfectly simple and indivisible, and exists every where, without any local presence. Whatever we discover externally by sensation; whatever we feel internally by reflection; all these are nothing but modifications of that one, simple, and necessarily existent being, and are not possest of any separate or distinct existence. Every passion of the soul; every configuration of matter, however different and various, inhere in the same substance, and preserve in themselves their characters of distinction, without communicating them to that subject, in which they inhere."

"My dear Tyndall—I find that in the midst of my work in Edinburgh I omitted to write to De Vrij, so I have just sent him a letter expressing my pleasure in my being able to co-operate in any plan for doing honour to old Benedict, for whom I have a most special respect."

"I have a great respect for the Nazarenism of Jesus — very little for later Christianity. But the only religion that appeals to me is prophetic Judaism. Add to it something from the best Stoics and something from Spinoza and something from Goethe, and there is a religion for men."

"...Lately I have been re-reading Spinoza (much read and little understood in my youth). But that noblest of Jews must have planted no end of germs in my brains, for I see that what I have to say is in principle what he had to say, in modern language."

"The movement of modern philosophy is back towards the position of the old Ionian philosophers, but strengthened and clarified by sound scientific ideas. If I publish my criticism on Comte, I should have to re-write it as a summary of philosophical ideas from the earliest times. The thread of philosophical development is not on the lines usually laid down for it. It goes from Democritus and the rest to the Epicureans, and then the Stoics, who tried to reconcile it with popular theological ideas, just as was done by the Christian Fathers. In the Middle Ages it was entirely lost under the theological theories of the time; but reappeared with Spinoza, who, however, muddled it up with a lot of metaphysics which made him almost unintelligible."

"The oldest recorded form of the rule, and that which has the most positive character, is contained in the command of the Jewish law, "Thou shalt love thy neighbour as thyself," (Leviticus xix. 18), (neighbour including "stranger that dwelleth with you," v. 34), which stands in the same relation to the individualistic maxim as Fraternity to Equity. The strength of Judaism as a social organisation has resided in its unflinching advocacy of freedom, within the law; equality, before the law; and fraternity, outside the law. I am not sure that, from the purely philosophical point of view, the form in which that great Jew, Spinoza, has stated the rule is not the best: "Desire nothing for yourself which you do not desire for others," (nihi sibi appetere quod reliquis hominibus non cupiant). (Ethics, iv. xviii.)"

"...The more a man knows about individual objects, the more he knows about God. Translating Spinoza's language into ours, we can say: The more a man knows about himself in relation to every kind of experience, the greater his chance of suddenly, one fine morning, realizing who in fact he is..."

"An immense role in the development of logic, and in preparing the ground for modern views on its subject matter, a role far from fully appreciated, was played by Spinoza. Like Leibniz, Spinoza rose high above the mechanistic limitations of the natural science of his time. Any tendency directly to universalise partial forms and methods of thinking only useful within the bounds of mechanistic, mathematical natural science was also foreign to him. Insofar as logic was preserved alongside the doctrine of substance, Spinoza treated it as an applied discipline by analogy with medicine, since its concern proved not to be the invention of artificial rules but the co-ordination of human intellect with the laws of thought understood as an ‘attribute’ of the natural whole, only as ‘modes of expression’ of the universal order and connection of things. He also tried to work out logical problems on the basis of this conception. Spinoza understood thought much more profoundly and, in essence, dialectically, which is why his figure presents special interest in the history of dialectics; he was probably the only one of the great thinkers of the pre-Marxian era who knew how to unite brilliant models of acutely dialectical thought with a consistently held materialist principle (rigorously applied throughout his system) of understanding thought and its relations to the external world lying in the space outside the human head. The influence of Spinoza's ideas on the subsequent development of dialectical thought can hardly be exaggerated. ‘It is therefore worthy of note that thought must begin by placing itself at the standpoint of Spinozism; to be a follower of Spinoza is the essential commencement of all Philosophy.’ [Lectures on the History of Philosophy, Hegel]"

"But orthodox religious scholasticism, in alliance with subjective idealist philosophy, has not ceased to flog Spinoza as a ‘dead dog’, treating him as a living and dangerous opponent. Elementary analysis reveals that the main principles of Spinoza’s thought directly contradict the conception of ‘thought’ developed by modern positivism all along the line. The most modern systems of the twentieth century still clash in sharp antagonism in Spinoza; and that obliges us to analyse the theoretical foundation of his conception very carefully, and to bring out the principles in it that, in rather different forms of expression perhaps, remain the most precious principles of any scientific thinking to this day, and as such are very heatedly disputed by our contemporary opponents of dialectical thought."

"In defining thought as an attribute Spinoza towered above any representative of mechanistic materialism and was at least two centuries in advance of his time in putting forward a thesis that Engels expressed in rather different words: ‘The point is, however, that mechanism (and also the materialism of the eighteenth century) does not get away from abstract necessity, and hence not from chance either. That matter evolves out of itself the thinking human brain is for him [Haeckel] a pure accident, although necessarily determined, step by step, where it happens. But the truth is that it is in the nature of matter to advance to the evolution of thinking beings, hence, too, this always necessarily occurs wherever the conditions for it (not necessarily identical at all places and times) are present.’ [Dialectics of Nature] That is what distinguishes materialism, sensible and dialectical, from mechanistic materialism that knows and recognises only one variety of ‘necessity’, namely that which is described in the language of mechanistically interpreted physics and mathematics. Yes, only Nature as a whole, understood as an infinite whole in space and time, generating its own partial forms from itself, possesses at any moment of time, though not at any point of space, all the wealth of its attributes, i.e. those properties that are reproduced in its makeup of necessity and not by a chance, miraculous coincidence that might just as well not have happened."

"Hence it inevitably follows logically, as Engels said, ‘that matter remains eternally the same in all its transformations, that none of its attributes can ever be lost, and therefore, also, that with the same iron necessity that it will exterminate on the earth its highest creation, the thinking mind, it must somewhere else and at another time again produce it.’ That was Spinoza's standpoint, a circumstance that seemingly gave Engels grounds for replying categorically and unambiguously to Plekhanov when he asked: ‘So in your opinion old Spinoza was right in saying that thought and extension were nothing but two attributes of one and the same substance?’ "Of course," answered Engels, "old Spinoza was quite right".’ Spinoza's definition means the following: in man, as in any other possible thinking creature, the same matter thinks as in other cases (other modi) only ‘extends’ in the form of stones or any other ‘unthinking body’; that thought in fact cannot be separated from world matter and counterposed to it itself as a special, incorporeal ‘soul’, and it (thought) is matter’s own perfection. That is how Herder and Goethe, La Mettrie and Diderot, Marx and Plekhanov (all great ‘Spinozists’) and even the young Schelling, understood Spinoza. [...] Spinoza said more than once that it was impermissible to represent thought as attribute in the image and likeness of human thought; it was only the universal property of substance that was the basis of any ‘finite thought’, including human thought, but in no case was it identical with it. To represent thought in general in the image and likeness of existing human thought, of its modus, or ‘particular case’, meant simply to represent it incorrectly, in ‘an incomplete way’, by a ‘model’, so to say, of its far from most perfected image (although the most perfected known to us)."

"If Spinoza had in fact tried to construct his philosophical system by the method that our contemporary positivism would have recommended to him, it is not difficult to imagine what he would have produced as a ‘system’. He would only have brought together the purely mechanical and religious, mystical ‘general ideas’ that were guiding all (or almost all) naturalists in his day. Spinoza understood very clearly that religious, theological mysticism was the inevitable complement of a purely mechanistic (geometrical, mathematical) world outlook, i.e. the point of view that considers the sole ‘objective’ properties of the real world to be only the spatial, geometrical forms and relations of bodies. His greatness was that he did not plod along behind contemporaneous natural science, i.e. behind the one-sided, mechanistic thinking of the coryphaei of the science of the day, but subjected this way of thinking to well substantiated criticism from the angle of the specific concepts of philosophy as a special science. This feature of Spinoza’s thinking was brought out clearly and explicitly by Friedrich Engels: ‘It is to the highest credit of the philosophy of the time that it did not let itself be led astray by the restricted state of contemporary natural knowledge, and that from Spinoza right to the great French materialists it insisted on explaining the world from the world itself and left the justification in detail to the natural science of the future.’ [Dialectics of Nature] That is why Spinoza has come down in the history of science as an equal contributor to its progress with Galileo and Newton, and not as their epigone, repeating after them the general ideas that could be drawn from their work. He investigated reality himself from the special, philosophical angle, and did not generalise the results and ready-made findings of other people’s investigation, did not bring together the general ideas of the science of his day and the methods of investigation characteristic of it, or the methodology and logic of his contemporary science. He understood that that way led philosophy up a blind alley, and condemned it to the role of the wagon train bringing up in the rear of the attacking army the latter’s own ‘general ideas and methods’, including all the illusions and prejudices incorporated in them. That is why he also developed ‘general ideas and methods of thought’ to which the natural science of the day had not yet risen, and armed future science with them, which recognised his greatness three centuries later through the pen of Albert Einstein, who wrote that he would have liked ‘old Spinoza’ as the umpire in his dispute with Niels Bohr on the fundamental problems of quantum mechanics rather than Carnap or Bertrand Russell, who were contending for the role of the ‘philosopher of modern science’ and spoke disdainfully of Spinoza’s philosophy as an ‘outmoded’ point of view ‘which neither science nor philosophy can nowadays accept’. Spinoza's understanding of thinking as the activity of that same nature to which extension also belonged is an axiom of the true modern philosophy of our century, to which true science is turning more and more confidently and consciously in our day (despite all the attempts to discredit it) as the point of view of true materialism."

"There is no other philosophy than that of Spinoza."

"The brilliance of the solution of the problem of the relation of thinking to the world of bodies in space outside thought (i.e. outside the head of man), which Spinoza formulated in the form of the thesis that thought and extension are not two substances, but only two attributes of one and the same substance, can hardly be exaggerated. This solution immediately rejected every possible kind of interpretation and investigation of thought by the logic of spiritualist and dualist constructions, so making it possible to find a real way out both from the blind alley of the dualism of mind and body and from the specific blind alley of Hegelianism. It is not fortuitous that Spinoza’s profound idea only first found true appreciation by the dialectical materialists Marx and Engels. Even Hegel found it a hard nut to crack. In fact, on the decisive point, he returned again to the position of Descartes, to the thesis that pure thought is the active cause of all the changes occurring in the ‘thinking body of man’, i.e. in the matter of the brain and sense organs, in language, in actions and their results, including in that the instruments of labour and historical events."

"The question of Spinozism is indeed central and indispensable to any proper understanding of Early Enlightenment European thought. Its prominence in European intellectual debates of the late seventeenth and early eighteenth century is generally far greater than anyone would suppose from the existing secondary literature; one of the chief aims of this present study is to demonstrate that there has been a persistent and unfortunate tendency in modern historiography to misconstrue and underestimate its significance. Admittedly, the term 'Spinosisme' as used in the French Enlightenment, or Spinozisterey, as it was called in Germany, was frequently employed, as in the campaign against Montesquieu, rather broadly to denote virtually the whole of the Radical Enlightenment, that is, all deistic, Naturalistic, and atheistic systems that exclude divine Providence, Revelation, and miracles, including reward and punishment in the hereafter, rather than strict adherence to Spinoza's system as such. Yet this does not mean that it was a vague or meaningless usage. On the contrary, the extremely frequent and extensive use of the terms Spinozism and Spinosistes in Early Enlightenment discourse, not least in Bayle, who devoted the longest single article in his Dictionnaire historique et critique to the subject of Spinoza and Spinosisme, is precisely intended to connect—and with considerable justification, as we shall see—Spinoza's philosophy with a wide-ranging network of other radical thought."

"...I depart tonight to spend a few days in Münster and am on that account very busy and distracted, else I would be writing more as to the possible advantages there might be in presenting to the public Spinoza's system in its true form and according to the intrinsic coherence of its parts. Its spectre has been haunting Germany for lo these many years, in all shapes and sizes and is regarded with reverence by believers and doubters alike. I am speaking not just of the petty-minded but of people with the finest minds."

"When he arrived in Amsterdam at age fifty-one [1683], Locke had published nothing. During what was clearly a transformational period, he used his time in Holland to talk with other independent thinkers who had been hounded into exile by the governments and churches of their own countries. Although Spinoza was dead, Locke certainly met many of the philosopher's admirers and enemies. He was well acquainted with nonconformist Protestant Collegiants, and his later writings would advocate complete toleration for all forms of Protestantism. At the time of Locke's death, his library contained all of Spinoza's published works as well as many political and religious disputations, in many languages, in which Spinoza's ideas were vigorously debated. Locke, like Hobbes, Adam Smith, and David Hume, is much more widely recognized than Spinoza in the United States as an influence upon the Enlightenment views of the American founders, but the more radical Spinoza's voice can be heard in both the Declaration of Independence and the Bill of Rights. It is not surprising that Thomas Jefferson's library contained Spinoza's collected works, which were more readily available at the end of the eighteenth century than in Locke's time."

"[Spinoza] this pure soul, this great realist, the first human being to attempt to become a citizen of the world. . . this down-to-earth passion."

"In 1676 Leibniz found a pretext to visit Spinoza in The Hague, having learned that Spinoza was at work on a philosophical treatise of great importance. Spinoza showed Leibniz the manuscript of the 'Ethics', and the two men discussed philosophy together over several days. Although there is no written record of their conversation, it seems likely that these discussions were among the most rewarding in the whole history of philosophy."

"...If we had the time we should now go on to present the ingenious theory of organism with which Spinoza focused the general ontological scheme specifically on the biological sphere, where mentality is ordinarily seen to be conjoined to physical fact, and particularly on the case of man. It must be enough to say that Spinoza makes it beautifully intelligible from his general premises that the quality and power of a mind are proportionate to the complexity of the body to which it corresponds, so that the perfection of the human body as a piece of physical organization is a direct yardstick for the perfection of the human mind which, as it were, conformally (or: isomorphously) duplicates the body's physical performance on the plane of thought."

"Surely, Spinoza's parallelism of attributes expressing differently but equivalently one and the same substance was a feat of genius and far superior to all other treatments of the problem at the time. Without interposing a synchronizing deity, as did others, it overcame Descartes' dualistic rift by a monistic reduction, yet retained the full severity of the disjunctions which that dualism had been designed to ensure."

"...Synge was over here selling out and gave me his play to read–a play which is to be produced by the Irish Literary Theatre. I criticised it. Synge says I have a mind like Spinoza! (Spinoza was a great Hebrew philosopher)..."

"From Descartes and Malebranche onward, the metaphysical value of the “idea” or archetype steadily deteriorated. It became a “thought,” an internal condition of cognition, as clearly formulated by Spinoza: “By 'idea' I understand a conception of the mind which the mind forms by reason of its being a thinking thing.” Finally Kant reduced the archetypes to a limited number of categories of understanding."

"You were one of the noblest, the most genuine people, who have ever walked this earth. And though both friend and foe know this, I don't think it unwarranted to verbally bear witness to it before your grave. For we know the world, we know Spinoza's fate. For the world could lay shadows around Nietzsche's memory as well. And therefore I conclude with the words: Peace to your ashes! Holy be thy name to all those to come!"

"...[H]e was one of the most illustrious advocates of religious toleration; when his landlords, members of a peaceful and tolerant Mennonite community, asked him whether he thought their religion was good, he said yes, it was good and they should stick to it. For although in his writings he urged us to strive towards a mystical sort of union with God, towards intellectual love and philosophical reconciliation with whatever fate should bring, he knew that his advice was meant for only a very select few, and that the rest, the common folk who are incapable of subordinating their lives to reason, would still need advice about how to lead a good life – the kind of advice that religion provides. This was fine as long as the religion was one that preached peace and unity, and did not breed fanaticism, hatred or despotic government. In the whole history of philosophy there is no figure as lonely as Spinoza."

"Through the seventeenth and eighteenth centuries, Bruno's ideas were widely imparted, borrowed, sounded ; almost never, though, with the name Giordano Bruno attached to them. Kepler once chided Galileo for omitting his debt to Bruno ; yet, we can discern Kepler's own indifference … Later generations would evoke Bruno's writings to the phrase, without quoting or acknowledging him. Recent scholarship on Spinoza, for example, cites Bruno's powerful exertion on his thought about infinity and on his style. Never does Spinoza cite Bruno by name."

"For years my mind was divided between Hegel and Spinoza. With youthful ingenuity I defended the dialectics of the former against Zeller, the founder of neo-Kantianism. The writings of Spinoza I knew by heart, and with loving understanding I gave expositions of his theory of affections and passions."

"Neokantianism represents in the last analysis nothing but a certain academic line of thought, which has supplied us with a better knowledge of Kant and a useful literature of educated people. Agnosticism, on the other hand, on account of its diffusion among the people, is an actual symptom of the present condition of certain social classes. The socialists would have good grounds for believing that this symptom is one of the evidences of the decadence of the bourgeoisie. It certainly stands in marked contrast to the heroic devotion to truth shown by the thought of the precursors of modern history, such as Bruno and Spinoza, or to that conventional assertiveness, which was typical of the thinkers of the 18th century, until the classic German philosophy gradually came upon the scene."

"The philosophy of a purely theoretical thinker, who contemplates all things from the point of view of things in themselves, belongs in the same class as the attempt to apply abstract thought to the entire field of consciousness without meeting any byways or stops. Look at Baruch Spinoza, that true hero of thought, who studied in his own person the way in which the emotions and passions, as expressions of his internal mechanism, transform themselves for him into objects of geometrical analysis! In the meantime, until the heroism of Baruch Spinoza shall become the matter-of-fact virtue of everyday life in the higher developed humanity of the future, and until myths, poetry, metaphysics and religion shall no longer overshadow the field of consciousness, let us be content that up to now, and for the present, philosophy in its differentiated and its improved sense has served, and serves, as a critical instrument and helps science to keep its formal methods and logical processes clear; that it helps us in our lives to reduce the obstacles, which the fantastic projections of the emotions, passions, fears and hopes pile in the way of free thought; that it helps and serves, as Spinoza himself would say, to vanquish imaginationem et ignorantiam."

"...For the present it would be a vain undertaking to try to make all these people understand this frank principle of communist ethics, a principle which declares that gratitude and admiration should come as a spontaneous gift from our fellow-beings. Many of them would not care to reach out for progress, were they sure of being told, in the words of Baruch Spinoza, that virtue is its own reward."

"...It is the eternal meaning of the sacrifice, to which no one can resist, unless animated by that faith, so difficult to sustain, which, perhaps, one man alone has been able to formulate in a plausible way—namely, Spinoza, with his Amor intellectualis Dei. What, quite wrongly, has been thought of in Spinoza as pantheism is simply the reduction of the field of God to the universality of the signifier, which produces a serene, exceptional detachment from human desire. In so far as Spinoza says—desire is the essence of man, and in so far as he institutes this desire in the radical dependence of the universality of the divine attributes, which is possible only through the function of the signifier, in so far as he does this, he obtains that unique position by which the philosopher—and it is no accident that it is a Jew detached from his tradition who embodies it—may be confused with a transcendent love. This position is not tenable for us."

"Regarding Spinoza, whom M. Arnauld has called the most impious and most dangerous man of this century, he was truly an Atheist, [i.e.,] he allowed absolutely no Providence dispensing rewards and punishments according to justice. ...The God he puts on parade is not like ours; he has no intellect or will. ...He fell well short of mastering the art of demonstration; he had only a mediocre knowledge of analysis and geometry; what he knew best was to make lenses for microscopes."

"Vygotsky studied the classical German philosophy on a professional level. In his student years began his acquaintance with the philosophy of Marxism, which he studied mainly using illegal editions. At this time was born Vygotsky's interest in the philosophy of Spinoza, who would remain his favorite thinker for the rest of his life."

"...I love Spinoza, because he, more than any other philosopher, led me to the complete conviction that certain things cannot be explained, that because of this one need not close one's eyes to them, but rather take them as one finds them."

"If I should name myself after anyone, then I know no one other better."

"Pantheism is as old as philosophy. It was taught in the old Greek schools — by Plato, by St. Augustine, and by the Jews. Indeed, one may say that Pantheism, under one of its various shapes, is the necessary consequence of all metaphysical inquiry, when pushed to its logical limits ; and from this reason do we find it in every age and nation. The dreamy contemplative Indian, the quick versatile Greek, the practical Roman, the quibbling Scholastic, the ardent Italian, the lively Frenchman, and the bold Englishman, have all pronounced it as the final truth of philosophy. Wherein consists Spinoza's originality? — what is his merit? — are natural questions, when we see him only lead to the same result as others had before proclaimed. His merit and originality consist in the systematic exposition and development of that doctrine — in his hands, for the first time, it assumes the aspect of a science. The Greek and Indian Pantheism is a vague fanciful doctrine, carrying with it no scientific conviction ; it may be true — it looks true — but the proof is wanting. But with Spinoza there is no choice : if you understand his terms, admit the possibility of his science, and seize his meaning; you can no more doubt his conclusions than you can doubt Euclid ; no mere opinion is possible, conviction only is possible."

"Such was Benedict Spinoza — thus he lived and thought. A brave and simple man, earnestly meditating on the deepest subjects that can occupy the human race, he produced a system which will ever remain as one of the most astounding efforts of abstract speculation — a system that has been decried, for nearly two centuries, as the most iniquitous and blasphemous of human invention ; and which has now, within the last sixty years, become the acknowledged parent of a whole nation's philosophy, ranking among its admirers some of the most pious and illustrious intellects of the age. The ribald Atheist turns out, on nearer acquaintance, to be a "God-intoxicated man." The blasphemous Jew becomes a pious, virtuous, and creative thinker. The dissolute heretic becomes a child-like, simple, self-denying and heroic man. We look into his works with calm earnestness, and read there another curious page of human history : the majestic struggle with the mysteries of existence has failed, as it always must fail ; but the struggle demands our warmest admiration, and the man our ardent sympathy. Spinoza stands out from the dim past like a tall beacon, whose shadow is thrown athwart the sea, and whose light will serve to warn the wanderers from the shoals and rocks on which hundreds of their brethren have perished."

"...The doctrine of Spinoza was of great importance, if for nothing more than having brought about the first crisis in modern Philosophy."

"...I am not so well read in Hobbes or Spinoza, as to be able to say what were their opinions in this matter [the life after death]. But, possibly, there be those who will think your lordship's authority of more use to them in the case than those justly decried names;"

"...Jews seem to have superiority as actors, chess-players, doctors, merchants (chiefly financiers), in metaphysics, music, poetry, and philology.... Of course, Jews have no Darwin. It took England 180 years after Newton before she could produce a Darwin, and as Britishers are five times the number of Jews, even including those of Russia, it would take, on the same showing, 900 years before they produce another Spinoza, or, even supposing the double superiority to be true, 450 years would be needed."

"[Spinoza] — the philosopher whom I trust most,... [Original in German: Der Philosoph, dem ich zumeist vertraue,...]"

"His [Spinoza's] correspondence is the most interesting book one can read in the world of uprightness and of humanity. [Original in German: Sei Briefwechsel sei das interessanteste Buch, das man in der Welt von Aufrichtigkeit, Menschenliebe lesen könne.]"

"Last night, I was diligently reluctant to read last in our saint [i.e. Spinoza] and thought of you. [Original in German: Gestern Abend war ich nur wider Willen fleisig und las noch zuletzt in unserm Heiligen und dachte an dich.]"

"I practice Spinoza, I read and read it again, and wait with longing for the fight over his corpse. I abstain from all judgment, but I confess that I am very much in agreement with Herder in these matters. [Original in German: Ich übe mich an Spinoza, ich lese und lese ihn wieder, und erwarte mit Verlangen biß der Streit über seinen Leichnam losbrechen wird. Ich enthalte mich alles Urtheils doch bekenne ich, daß ich mit Herdern in diesen Materien sehr einverstanden bin.]"

"He [Spinoza] does not prove the existence of God, existence is God. And if for this reason others would brand him Atheum then I would praise him and call him theissimum and christianissimum. [Original in German: Du erkennst die höchste Realität an, welche der Grund des ganzen Spinozismus ist, worauf alles übrige ruht, woraus alles übrigefliest. Er [Spinoza] beweist nicht das Daseyn Gottes, das Daseyn ist Gott. Und wenn ihn andre deshalb Atheum schelten, so mögte ich ihn theissimum ja christianissimum nennen und preisen.]"

"You know that I do not share your opinion in this matter. That Spinozism and Atheism are to me two different things. That when I read Spinoza I can only explain him by reference to himself and that if it came to naming a book which, of all that I know, most agrees with my way of seeing things, then I would have to name the Ethics—even though by nature I do not share his way of seeing things. [Original in German: Du weißt daß ich über die Sache selbst nicht deiner Meinung bin. Daß mir Spinozismus und Atheismus zweyerlei ist. Daß ich den Spinoza wenn ich ihn lese mir nur aus sich selbst erklären kann, und daß ich, ohne seine Vorstellungsart von Natur selbst zu haben, doch wenn die Rede wäre ein Buch anzugeben, das unter allen die ich kenne, am meisten mit der meinigen übereinkommt, die Ethik nennen müsste.]"

"Spinoza, then, emerged as the supreme philosophical bogeyman of Early Enlightenment Europe. Admittedly, historians have rarely emphasized this. It has been much more common, and still is, to claim that Spinoza was rarely understood and had very little influence, a typical example of an abiding historiographical refrain which appears to be totally untrue but nevertheless, since the nineteenth century, has exerted an enduring appeal for all manner of scholars. In fact, no one else during the century 1650–1750 remotely rivalled Spinoza's notoriety as the chief challenger of the fundamentals of revealed religion, received ideas, tradition, morality, and what was everywhere regarded, in absolutist and non-absolutist states alike, as divinely constituted political authority."
