Philosophers From Germany

"Criticism alone can sever the root of materialism, fatalism, atheism, free-thinking, fanaticism, and superstition, which can be injurious universally; as well as of idealism and skepticism, which are dangerous chiefly to the Schools, and hardly allow of being handed on to the public."

"I have therefore found it necessary to deny knowledge in order to make room for faith."

"When Galilei let balls of a particular weight, which he had determined himself, roll down an inclined plain, or Torricelli made the air carry a weight, which he had previously determined to be equal to that of a definite volume of water; or when, in later times, Stahl changed metal into lime, and lime again into metals, by withdrawing and restoring something, a new light flashed on all students of nature. They comprehended that reason has insight into that only, which she herself produces on her own plan, and that she must move forward with the principles of her judgments, according to fixed law, and compel nature to answer her questions, but not let herself be led by nature, as it were in leading strings, because otherwise accidental observations made on no previously fixed plan, will never converge towards a necessary law, which is the only thing that reason seeks and requires. Reason, holding in one hand its principles, according to which concordant phenomena alone can be admitted as laws of nature, and in the other hand the experiment, which it has devised according to those principles, must approach nature, in order to be taught by it: but not in the character of a pupil, who agrees to everything the master likes, but as an appointed judge, who compels the witnesses to answer the questions which he himself proposes. Therefore even the science of physics entirely owes the beneficial revolution in its character to the happy thought, that we ought to seek in nature (and not import into it by means of fiction) whatever reason must learn from nature, and could not know by itself, and that we must do this in accordance with what reason itself has originally placed into nature. Thus only has the study of nature entered on the secure method of a science, after having for many centuries done nothing but grope in the dark."

"Abbot Terrasson tells us that if the size of a book were measured not by the number of its pages but by the time required to understand it, then we could say about many books that they would be much shorter were they not so short."

"Mathematics, from the earliest times to which the history of human reason can reach, has followed, among that wonderful people of the Greeks, the safe way of science. But it must not be supposed that it was as easy for mathematics as for logic, in which reason is concerned with itself alone, to find, or rather to make for itself that royal road. I believe, on the contrary, that there was a long period of tentative work (chiefly still among the Egyptians), and that the change is to be ascribed to a revolution, produced by the happy thought of a single man, whose experiments pointed unmistakably to the path that had to be followed, and opened and traced out for the most distant times the safe way of a science. The history of that intellectual revolution, which was far more important than the passage round the celebrated Cape of Good Hope, and the name of its fortunate author, have not been preserved to us. ... A new light flashed on the first man who demonstrated the properties of the isosceles triangle (whether his name was Thales or any other name), for he found that he had not to investigate what he saw hi the figure, or the mere concepts of that figure, and thus to learn its properties; but that he had to produce (by construction) what he had himself, according to concepts a priori, placed into that figure and represented in it, so that, in order to know anything with certainty a priori, he must not attribute to that figure anything beyond what necessarily follows from what he has himself placed into it, in accordance with the concept."

"Human reason has this peculiar fate that in one species of its knowledge it is burdened by questions which, as prescribed by the very nature of reason itself, it is not able to ignore, but which, as transcending all its powers, it is also not able to answer."

"Newton... (after having remarked that geometry only requires two of the mechanical actions which it postulates, namely, to describe a straight line and a circle) says: geometry is proud of being able to achieve so much while taking so little from extraneous sources. One might say of metaphysics, on the other hand: it stands astonished, that with so much offered it by pure mathematics it can effect so little. In the meantime, this little is something which mathematics indispensably requires in its application to natural science, which, inasmuch as it must here necessarily borrow from metaphysics, need not be ashamed to allow itself to be seen in company with the latter."

"I have in this treatise followed the mathematical method, if not with all strictness, at least imitatively, not in order, by a display of profundity, to procure a better reception for it, but because I believe such a system to be quite capable of it, and that perfection may in time be obtained by a cleverer hand, if stimulated by this sketch, mathematical investigators of nature should find it not unimportant to treat the metaphysical portion, which anyway cannot be got rid of, as a special fundamental department of general physics, and to bring it into unison with the mathematical doctrine of motion."

"Natural science is throughout either a pure or an applied doctrine of motion."

"All true metaphysics is taken from the essential nature of the thinking faculty itself, and therefore in nowise invented, since it is not borrowed from experience, but contains the pure operations of thought, that is, conceptions and principles à priori, which the manifold of empirical presentations first of all brings into legitimate connection, by which it can become empirical knowledge, i.e. experience. ...mathematical physicists were thus quite unable to dispense with such metaphysical principles..."

"All natural philosophers, who wished to proceed mathematically in their work, have hence invariably (although unknown to themselves) made use of metaphysical principles, and must make use of such, it matters not how energetically they may otherwise repudiate any claim of metaphysics on their science."

"I maintain that in every special natural doctrine only so much science proper is to be met with as mathematics; for... science proper, especially of nature, requires a pure portion, lying at the foundation of the empirical, and based upon à priori knowledge of natural things. ...the conception should be constructed. But the cognition of the reason through construction of conceptions is mathematical. A pure philosophy of nature in general, namely, one that only investigates what constitutes a nature in general, may thus be possible without mathematics; but a pure doctrine of nature respecting determinate natural things (corporeal doctrine and mental doctrine), is only possible by means of mathematics; and as in every natural doctrine only so much science proper is to be met with therein as there is cognition à priori, a doctrine of nature can only contain so much science proper as there is in it of applied mathematics."

"Die menschliche Vernunft hat hier, wie allerwärts in ihrem reinen Gebrauche, so lange es ihr an Kritik fehlt, vorher alle mögliche unrechte Wege versucht, ehe es ihr gelingt, den einzigen wahren zu treffen."

"Im Reiche der Zwecke hat alles entweder einen Preis oder eine Würde. Was einen Preis hat, an dessen Stelle kann auch etwas anderes als Äquivalent gesetzt werden; was dagegen über allen Preis erhaben ist, mithin kein Äquivalent verstattet, das hat eine Würde."

"Handle so, daß du die Menschheit, sowol in deiner Person, als in der Person eines jeden andern, jederzeit zugleich als Zweck, niemals bloß als Mittel brauchest."

"... happiness is not an ideal of reason, but of imagination, resting on merely empirical grounds,"

"Morality is thus the relation of actions to the autonomy of the will, that is, to a possible giving of universal law through its maxims. An action that can coexist with the autonomy of the will is permitted; one that does not accord with it is forbidden. A will whose maxims necessarily harmonize with the laws of autonomy is a holy, absolutely good will. The dependence upon the principle of autonomy of a will that is not absolutely good (moral necessitation) is obligation. This, accordingly, cannot be attributed to a holy being. The objective of an action from obligation is called duty."

"Even if there never have been actions arising from such pure sources, what is at issue here is not whether this or that happened; that, instead, reason by itself and independently of all appearances commands what ought to happen; that, accordingly, actions of which the world has perhaps so far given no example, and whose very practicability might be very much doubted by one who bases everything on experience, are still inflexibly commanded by reason … because … duty … lies, prior to all experience, in the idea of a reason determing the will by means of apriori grounds."

"I do not, therefore, need any penetrating acuteness to see what I have to do in order that my volition be morally good. Inexperienced in the course of the world, incapable of being prepared for whatever might come to pass in it, I ask myself only: can you also will that your maxim become a universal law?"

"Today, at any leading American university, a Kant, with all his dithering about God, freedom, and immortality, or even a Hume, wouldn't survive a year in graduate school, much less get hired as an instructor."

"Kant believed that the concept of time is a prior condition of our minds that affects our experience of the world, but this does not explain why different human societies have had different concepts of time and have assigned different degrees of significance to the temporal aspect of phenomena. ...instead of being a prior condition, our concept of time should be regarded as a consequence of our experience of the world, the result of a long evolution. ...In recent years it has become clear that all our mental abilities are potential capacities which we can only realize in practice by learning how to use them."

"The man Butler, whose works were perhaps known to the man Kant, wished to save the belief in the immortality of the soul, and with this object he made it independent of belief in God. The first chapter of his Analogy treats, as I have said, of the future life, and the second of the government of God by rewards and punishments. And the fact is that, fundamentally, the good Anglican bishop deduces the existence of God from the immortality of the soul. And as this deduction was the good Anglican bishop's starting-point, he had not to make that somersault which at the close of the same century the good Lutheran philosopher had to make. Butler, the bishop, was one man and Kant, the professor, another man."

"Kant's questions are so strange and arresting that no one who has once heard them ever forgets them. It is just the reverse with his answers to them: no one can ever remember what these are! And there is a simple reason for this: the questions never get answered at all. Once they have served as an excuse for the darkening of sufficient area of wood-pulp, they just get lost."

"Kant's 'discovery' went thus. Any property that a real x had, an imaginary x could have, and any property that an imaginary x could have, a real x could have. So Existence is not a property. (Hearty applause, maintained steadily for 200 years so far.)"

"”Prussia,” remarked Mirabeau, ”is not a state with an army, but an army with a state.” And the state, which was run with the efficiency and soullessness of a factory, became all; the people were little more than cogs in the machinery. Individuals were taught not only by the kings and the drill sergeants but by the philosophers that their role in life was one of obedience, work, sacrifice and duty. Even Kant preached that duty demands the suppression of human feeling…"

"Even when altruism is allowed (as, for example, in Gary Becker's model of rational allocation), it is assumed that the altruistic actions are undertaken because they promote each person's own interests; there are personal gains to the altruist's own welfare, thanks to sympathy for others. No role is given to any sense of commitment about behaving well or to pursuing some selfless objective. All this leaves out, on the one hand, the evil passions that early theorists of capitalism contrasted with selfinterest and, on the other, the social commitments that Kant analyzed in The Critique of Practical Reason and that Adam Smith discussed in The Theory of Moral Sentiments."

"Einstein has not — as you sometimes hear — given the lie to Kant’s deep thoughts on the idealization of space and time; he has, on the contrary, made a large step towards its accomplishment."

"I should liken Kant to a man at a ball, who all evening has been carrying on a love affair with a masked beauty in the vain hope of making a conquest, when at last she throws off her mask and reveals herself to be his wife."

"From childish fear springs the desire to externalise the ego. Metaphysicians do this in thought: Kant, who, in real life, never went more than ten miles from his native city of Königsberg, maintained that the whole of space existed only in his imagination. This grandiose philosophy was merely the obverse of his practical timidity."

"[T]here used to be in the old days three intellectual arguments for the existence of God, all of which were disposed of by Immanuel Kant in the Critique of Pure Reason; but no sooner had he disposed of those arguments than he invented a new one, a moral argument, and that quite convinced him. He was like many people: in intellectual matters he was skeptical, but in moral matters he believed implicitly in the maxims that he had imbibed at his mother's knee. That illustrates what the psychoanalysts so much emphasize — the immensely stronger hold upon us that our very early associations have than those of later times."

"I, for one, while I would not choose to dismiss Kant, am certainly prepared to dismiss his writing style. It was, indeed, in his own day, profitably parodied by Fichte."

"Immanuel Kant was the first hippie in history."

"I was shocked many years ago when a physicist said to me that Kant was the greatest astrophysicist in a hundred-year period. And I asked “Why do you say that? You talk about Kant-Lagrange hypothesis?” He said “No, that was only a hypothesis. Kant showed by a very eloquent geometrical argument that we live near the edge of landscape galaxy in the center of the sphere that resembles Andromeda nebula”. I never heard of that, no philosopher told me that, no historian of philosophy told me that, an astronomer told me that! It was Steven Weinberg; he then said that Kant was the only astrophysicist in about a hundred years who believed that star clustering could be accounted for by gravitation alone."

"Individualism, united with altruism, has become the basis of our western civilization. It is the central doctrine of Christianity ('love your neighbor,' say the Scriptures, not 'love your tribe'); and it is the core of all ethical doctrines which have grown from our civilization and stimulated it. It is also, for instance, Kant's central practical doctrine ("always recognize that human individuals are ends, and do not use them as mere means to your end.")"

"For Kant, there are no different religions, but rather different forms of belief in divine revelation [...] among which Christianity, as far as we know, is the most appropriate."

"Kant's view of the nature of what is "actually real" remained unaltered throughout his life. Reality is in itself a system of existing thought-essences brought into a unity by teleological relations that are intuitively thought by the Divine intellect, and by this very act of thought posited as real. ...If one... makes Kant either a sceptical agnostic who teaches the unknowableness of things-in-themselves, or a subjective idealist for whom there is no reality in itself at all, he will never be able to make anything of his philosophy. ...Kant is no forbidding or threatening name, but a kindly disposed patron. It happens that for many the Critique of Pure Reason is the first philosophical book that they seriously attempt to read. ...the book is not well suited to this purpose. Kant himself would not have recommended it. He did not even write the Prolegomena for pupils, but for future teachers of philosophy. ...They presuppose nothing less than an acquaintance with the entire state of philosophy at the time, with dogmatism and scepticism, with Leibniz and Hume. ...Kant's philosophy is the door to the philosophy of our century, and the door to the Kantian philosophy is the Critique of Pure Reason."

"Nothing works a more complete and penetrating disaster than every "impersonal" duty, every sacrifice before the Moloch of abstraction.—To think that no one has thought of Kant's categorical imperative as dangerous to life! … What destroys a man more quickly than to work, think and feel without inner necessity, without any deep personal desire, without pleasure—as a mere automaton of duty? That is the recipe for decadence, and no less for idiocy. … Instinct at fault in everything and anything, instinct as a revolt against nature, German decadence as a philosophy—that is Kant!"

"The bridge of thoughts and sighs that spans the whole history of the Aryan world has its first arch in the Vedas, its last in Kant’s Critique. While in the Veda we may study the childhood, we may study in Kant’s Critique of pure Reason the perfect manhood of the Aryan mind."

"As Immanuel Kant pointed out long ago, learning to learn is one of the things that we cannot learn from experience. [see Critique of Pure Reason quote above on à priori and à posteriori knowledge] ...So although sensations give us "occasions" to learn, this cannot be what makes us "able", to learn, because we first must have the additional knowledge that our brains would need, as Kant has said, to "produce representations" and then "to connect" them. Such additional knowledge would also include inborn ways to recognize correlations and other relations among sensations. I suspect that... our brains are already innately endowed with machinery to help us "to compare, to connect, or to separate" objects so that we can represent them as existing in space."

"I might...say that to all those à priori moralists who deem it necessary to argue at all, utilitarian arguments are indispensable...I cannot help referring, for illustration, to a systematic treatise by one of the most illustrious of them, the Metaphysics of Ethics, by Kant. This remarkable man, whose system of thought will long remain one of the landmarks in the history of philosophical speculation, does, in the treatise in question, lay down an universal first principle as the origin and ground of moral obligation; it is this:—'So act, that the rule on which thou actest would admit of being adopted as a law by all rational beings.' But when he begins to deduce from this precept any of the actual duties of morality, he fails, almost grotesquely, to show that there would be any contradiction, any logical (not to say physical) impossibility, in the adoption by all rational beings of the most outrageously immoral rules of conduct. All he shows is that the consequences of their universal adoption would be such as no one would choose to incur."

"Kant was probably the worst writer ever heard of on earth before Karl Marx. Some of his ideas were really quite simple, but he always managed to make them seem unintelligible. I hope he is in Hell."

"What is the attraction of Kuhn’s account of science? It has its roots far back in time, with the biggest self-deluder of all, Immanuel Kant. The hand of Kant lies behind both Bohr and Kuhn. In his epic and epically incomprehensible masterpiece The Critique of Pure Reason (1781), Kant pulled off the grandest intellectual hocus-pocus in scholarly history. […] Kant argued that what have been taken to be features of a mind-independent reality—the structure of space and time, the existence of cause and effect, the law of conservation of energy—are actually imposed upon our experience by the mind itself. We have no justification for thinking that reality is intrinsically spatiotemporal or causally structured. But we are nonetheless eternally destined to experience the world in those terms because those are the intellectual and perceptive structures we must bring to our experience. Kant’s argumentation for this Parmenidean thesis is famously obscure, and his writing forbiddingly impenetrable. But the moral he wanted to draw, which goes by the name of transcendental idealism, is easily summarized. I just did. And for whatever reason, this conclusion of Kant’s has been attracting people like a siren’s call ever since. Remarkably, many people just want Kant’s conclusion to be true."

"Kant (Immanuel), Royal Professor of Morals and Metaphysics in the University of Konigsberg, is considered by his admirers as the greatest philosopher that Germany ever produced. Were we to form an estimate of his merits from the different views that have been given in English of his celebrated system, we certainly should not consider him as entitled to that character; for those views are obscured by new and uncouth terms, and are altogether wrapt up in a style which approaches nearer to jargon than to the luminous composition of a man who thinks with clearness and precision. We readily admit, that it is very difficult to translate a novel system of metaphysics from one language into another; for the translator, to perform his task properly, must be not only a complete master of both languages, but also a profound metaphysician; and not one of the translators or abridgers of the works of Kant into our language appears to us possessed of both these qualities. Despairing, from our scanty knowledge of the German language, of performing ourselves what so many others have failed to perform, we have applied for assistance to an illustrious Frenchman, who has resided many years in Germany, who is master of both languages, who is a profound metaphysician, and whose name, were we at liberty to publish it, would reflect luster upon our Work. From him we have reason to expect a clear and comprehensive view of the Critical Philosophy, as Kant terms his system; but should we be disappointed of our expectation, we shall, under that title, lay before our readers a specimen of the system from the different views of it which have been published in our own tongue."

"Kant truly says "it is the fate of human reason in speculation to build as rapidly as possible, and only when the edifice is completed to examine the solidity of its foundations." And the source of such carelessness he finds in this, that knowledge often consisting in the analysis of our conceptions, we are led to pay exclusive attention to them, rather than to their origin."

"Kant's critical philosophy is the most elaborate fit of panic in the history of the Earth."

"Unlike vision, touch, or smell, which are prewired and based on Kantian a priori knowledge, the spatial map presents us with a new type of representation, one based on a combination of a priori knowledge and learning."

"Each sensory system first analyzes and deconstructs, then restructures the raw, incoming information to its own built-in connections and rules—shades of Immanuel Kant."

"[…]Kant believed that world peace was possible only if the enlightened elites in each country worked hard to promote conscience. Without conscience there would be no peace, no matter how much efforts a society of nations would make. I am not sure that Kant’s notion of conscience was the same as Dr. Hong’s and Tai Ji Men’s. Kant’s one was deeply rooted in a Protestant sense of guilt and sin, and he saw it more as an inner tribunal delivering an internal verdict of guilt for the bad actions we have performed. Yet, his idea of a necessary connection between peace and conscience remains valid."

"Immanuel Kant was a real pissant who was very rarely stable."

"The brightest object known was the sun. Therefore, the stars were assumed to be like the sun, and distances could be estimated from their apparent faintness. In this way, the conception of a stellar system, isolated in space, was formulated as early as 1750. The author was Thomas Wright... But Wright's speculations went beyond the Milky Way. A single stellar system, isolated in the universe, did not satisfy his philosophical mind. He imagined other, similar systems and, as visible evidence of their existence, referred to the mysterious clouds called "nebulæ." Five years later, Immanuel Kant developed Wright's conception in a form that endured, essentially unchanged, for the following century and a half. Some of Kant's remarks concerning the theory furnish an excellent example or reasonable speculation based on the principle of uniformity. ...The theory, which came to be known as the theory of island universes, found a permanent place in the body of philosophical speculation. ...Toward the end of the nineteenth century... the accumulation of observational data brought into prominence the problem of the status of the nebulæ and, with it, the theory of the island universes as a possible solution."
