"Kant's critical philosophy is the most elaborate fit of panic in the history of the Earth."
"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 (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."
"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 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."
"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."
"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."
"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."
"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!"
"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."
"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."
"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.")"
"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."
"Immanuel Kant was the first hippie in history."
"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."
"[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."
"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."
"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."
"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."
"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."
"”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…"
"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.)"
"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."
"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 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."
"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."
"The third of this kind of principles is : matter neither originates nor perishes; all the changes in the world concern form only ; a postulate which on the recommendation of common sense has spread through all philosophical schools, not because it is to be taken as having been found so, or as having been demonstrated by arguments a priori, but because if we were to admit that matter itself is fleeting and transitory, nothing at all that is stable and lasting would be left any longer to serve for the explication of phenomena according to universal and perpetual laws, and hence nothing at all would be left for the exercise of the intellect."
"The second is the partiality for unity proper to the philosophical mind, whence this wide-spread canon has flown forth: principles are not to be multiplied beyond supreme necessity, to which we give in our adhesion, not because we have insight into causal unity in the world either by reason or experience, but as seeking it by an impulse of the intellect which seems to itself to have by thus much advanced in the explication of phenomena, by as much as it is granted to it to descend from the same principle to a greater number of consequences,"
"To these spurious principles must be added some others of great affinity with them… First, that by which we assume that everything in the universe is done according to the order of nature, which principle by Epicurus was proclaimed without any restriction, and by all other philosophers unanimously with extremely rare exceptions, not to be admitted but from supreme necessity."
"The spurious axioms of the third kind from conditions proper to the subject whence they are transferred rashly to the object are plentiful, not, as in those of the Second Class, because the only way to the intellectual concept lies through the sensuous data, but because only by aid of the latter can the concept be applied to that which is given by experience, that is, can we know whether something is contained under a certain intellectual concept or not. To this class belongs the threadbare one of the schools: whatever exists contingently does at some time not exist. This spurious principle springs from the poverty of the intellect, having insight frequently into the nominal, rarely into the real, marks of contingency or necessity."
"The prejudices of the second species, since they impose upon the intellect by the sensual conditions restricting the mind if it wishes in certain cases to attain to what is intellectual, lurk more deeply. One of them is that which affects knowledge of quantity, the other that affecting knowledge of qualities generally. The former is: every actual multiplicity can be given numerically, and hence, every infinite quantity; the latter, whatever is impossible contradicts itself. In either of them the concept of time, it is true, does not enter into the very notion of the predicate, nor is it attributed as a qualification to the subject. But yet it serves as a means for forming an idea of the predicate, and thus, being a condition, affects the intellectual concept of the subject to the extent that the latter is only attained by its aid."
"they cudgel their brains with absurd questions, such as, for instance, why God did not make the world many centuries earlier. They persuade themselves that it is easy to conceive, to be sure, how God may discern what is present, that is, what is actual in the time in which he is, but how He may foresee what is future, that is, what is actual in the time in which He is not yet, they deem an intellectual difficulty; as if the existence of the Necessary Being descended through all the moments of an imaginary time, and, having already exhausted a part of His duration, saw before Him the eternity He was yet to live simultaneously with the present events of the world. All these difficulties upon proper insight into the notion of time vanish like smoke."
"A spurious axiom of the first class is: Whatever is, is somewhere and sometime."
"The method of the science not being practiced much nowadays, except what logic prescribes to all sciences generally, that fitted for the peculiar nature of metaphysics being simply ignored, it is no wonder that those who everlastingly turn the Sisyphean stone of this inquiry do not seem so far to have made much progress. Though here I neither can nor will expatiate upon so important and extensive a subject, I shall briefly shadow forth what constitutes no despicable part of this method, namely, the infection between sensuous and intellectual cognition, not only as creeping in on those incautious in the application of principles, but even producing spurious principles under the appearance of axioms."
"The use of the intellect in the sciences whose primitive concepts as well as axioms are given by sensuous intuition is only logical, that is, by it we only subordinate cognitions to one another according to their relative universality conformably to the principle of contradiction, phenomena to more general phenomena, and consequences of pure intuition to intuitive axioms. But in pure philosophy, such as metaphysics, in which the use of the intellect in respect to principles is real, that is to say, where the primary concept of things and relations and the very axioms are given originally by the pure intellect itself, and not being intuitions do not enjoy immunity from error, the method precedes the whole science, and whatever is attempted before its precepts are thoroughly discussed and firmly established is looked upon as rashly conceived and to be rejected among vain instances of mental playfulness."
"If it were right to overstep a little the limits of apodictic certainty befitting metaphysics, it would seem worth while to trace out some things pertaining not merely to the laws but even to the causes of sensuous intuition, which are only intellectually knowable. Of course the human mind is not affected by external things, and the world does not lie open to its insight infinitely, except as far as itself together with all other things is sustained by the same infinite power of one. Hence it does not perceive external things but by the presence of the same common sustaining cause; and hence space, which is the universal and necessary condition of the joint presence of everything known sensuously, may be called the phenomenal omnipresence, for the cause of the universe is not present to all things and everything, as being in their places, but their places, that is the relations of the substances, are possible, because it is intimately present to all. Furthermore, since the possibility of the changes and successions of all things whose principle as far as sensuously known resides in the concept of time, supposes the continuous existence of the subject whose opposite states succeed; that whose states are in flux, lasting not, however, unless sustained by another; the concept of time as one infinite and immutable in which all things are and last, is the phenomenal eternity of the general cause} But it seems more cautious to hug the shore of the cognitions granted to us by the mediocrity of our intellect than to be carried out upon the high seas of such mystic investigations, like Malebranche, whose opinion that we see all things in God is pretty nearly what has here been expounded."
"Several actual worlds without one another are not, therefore, impossible by the very concept, as Wolf hastily concluded from the notion of a complex or multiplicity which he deemed sufficient to a whole, as such, but only on condition that there exist but one necessary cause of all things. If several are admitted, several worlds without one another will be possible in the strictest metaphysical sense."
"A whole from necessary substances is impossible. The whole, therefore, of substances is a whole of contingent things, and the world consists essentially of only contingent things."
"The sham cause in physical influence consists in rashly assuming that the commerce of substance and transitive forces is sufficiently knowable from their mere existence. Hence it is not so much a system as rather the neglect of all philosophical system as a superfluity in the argument. Freeing the concept from this defect, we shall have a species of commerce alone deserving to be called real, and from which the whole constituting the world merits being called real, and not ideal or imaginary."
"The question of the principle of the form of the intelligible world turns, therefore, upon making apparent in what manner it is possible for several substances to be in mutual commerce, and for this reason to pertain to the same whole, which is called world. We do not here consider the world, let it be understood, as to matter, that is, as to the nature of the substances of which it consists, whether they be material or immaterial, but as to form, that is to say, how among several things taken separately a connection, and among them all, totality can have place."
"Space is employed as the type even of the concept of time itself, representing it by a line, and its limits — moments — by points. Time, on the other had, approaches more to a universal and rational concept, comprising under its relations all things whatsoever, to wit, space itself, and besides, those accidents which are not comprehended in the relations of space, such as the thoughts of the soul. Again, time, besides this, though it certainly does not dictate the laws of reason, yet constitutes the principal conditions tinder favor of which the mind compares its notions according to the laws of reason. Thus, I cannot judge what is impossible except by predicating a and not-a of the same subject at the same time."
"Nature, therefore, is subject with absolute precision to all the precepts of geometry as to all the properties of space there demonstrated, this being the subjective condition, not hypothetically but intuitively given, of every phenomenon in which nature can ever be revealed to the senses."
"The concept of space, therefore, is a pure intuition, being a singular concept, not made up by sensations, but itself the fundamental form of all external sensation."
"The concept of space is not abstracted from external sensations."
"It is absurd to excite reason against the primary postulates of pure time, as, for example, continuity, etc., since they follow from laws prior and superior to which nothing is found, and since reason herself in the use of the principle of contradiction cannot dispense with the support of this concept, so primitive and original is it."
"Those who assert the objective reality of time either conceive of it as a continuous flow in what exists, without, however, any existing thing, as is done especially by the English philosophers, an absurd fiction, or as something real abstracted from the succession of inner states, as it has been put by Leibnitz and his followers."
"Let the letters a b c denote the three angular points of a rectilineal triangle. If the point did move continuously over the lines ab, bc, ca, that is, over the perimeter of the figure, it would be necessary for it to move at the point b in the direction ab, and also at the same point b in the direction bc. These motions being diverse, they cannot be simultaneous. There-fore, the moment of presence of the movable point at vertex b, considered as moving in the direction ab, is different from the moment of presence of the movable point at the same vertex b, considered as moving in the same direction bc. But between two moments there is time; therefore, the movable point is present at point b for some time, that is, it rests. Therefore it does not move continuously, which is contrary to the assumption. The same demonstration is valid for motion over any right lines including an assignable angle. Hence a body does not change its direction in continuous motion except by following a line no part of which is straight, that is, a curve, as Leibnitz maintained."
"Phenomena of the external sense are examined and set forth in physics; those of the internal sense in empirical psychology. Pure mathematics considers space in geometry and time in pure mechanics. To these is to be added a certain concept, intellectual to be sure in itself, but whose becoming actual in the concrete requires the auxiliary notions of time and space in the successive addition and simultaneous juxtaposition of separate units, which is the concept of number treated in arithmetic."
"Now the maximum of perfection is called ideal, by Plato, Idea — for instance, his Idea of a Republic — and is the principle of all that is contained under the general notion of any perfection, inasmuch as the lesser grades are not thought determinable but by limiting the maximum. But God, the Ideal of perfection, and hence the principle of cognition, is also, as existing really, the principle of the creation of all perfection."
"The sensuous may be exceedingly distinct, while intellectual concepts are extremely confused. The former we observe in the prototype of sensuous knowledge geometry; the latter, in the organon of all intellectual concepts, metaphysics. It is evident how much toil the latter is expending to dispel the fogs of confusion darkening the common intellect, though not always with the happy success of the former science."
