Immanuel Kant Quotes

The greatest and perhaps only utility of all philosophy of pure reason is thus only negative, namely that it does not serve for expansion, as an organon, but rather, as a discipline, serves for the determination of boundaries, and instead of discovering truth it has only the silent merit of guarding against errors

Even philosophers will praise war as ennobling mankind, forgetting the Greek who said: War is bad in that it begets more evil than it kills.

War seems to be ingrained in human nature, and even to be regarded as something noble to which man is inspired by his love of honor, without selfish motives.

Les esprits qui ont le sentiment du sublime sont entraînés insensiblement vers les sentiments élevés de l’amitié, du mépris du monde, de l’éternité, par le calme et le silence d’une soirée d’été, alors que la lumière tremblante des étoiles perce les ombres de la nuit, et que la lune solitaire paraît à l’horizon. Le jour brillant inspire l’ardeur du travail et le sentiment de la joie. Le sublime émeut, le beau charme.

A man abandoned by himself on a desert island would adorn neither his hut nor his person; nor would he seek for flowers, still less would he plant them, in order to adorn himself therewith. It is only in society that it occurs to him to be not merely a man, but a refined man after his kind (the beginning of civilization). For such do we judge him to be who is both inclined and apt to communicate his pleasure to others, and who is not contented with an object if he cannot feel satisfaction in it in common with others. Again, every one expects and requires from every one else this reference to universal communication of pleasure, as it were from an original compact dictated by humanity itself.

"The problem of organizing a state, however hard it may seem, can be solved even for a race of devils, if only they are intelligent. The problem is: "Given a multitude of rational beings requiring universal laws for their preservation, but each of whom is secretly inclined to exempt himself from them, to establish a constitution in such a way that, although their private intentions conflict, they check each other, with the result that their public conduct is the same as if they had no such intentions.

Конституция, която цели най-голямата човешка свобода според закони, които правят така, че свободата на всеки да може да съществува заедно с тази на всички останали.

...whose true object is to shed the clearest light on every step which reason takes.

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.

Enlightenment is man's emergence from his self-imposed immaturity. Nothing is required for this enlightenment except freedom; and the freedom in question is the least harmful of all, namely, the freedom to use with and publicly in all matters.

The schematicism by which our understanding deals with the phenomenal world ... is a skill so deeply hidden in the human soul that we shall hardly guess the secret trick that Nature here employs.

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.

Two things fill the mind with ever-increasing wonder and awe, the more often and the more intensely the mind of thought is drawn to them: the starry heavens above me and the moral law within me.

If the intuition must conform to the nature of the objects, I do not see how we can know anything of them a priori. If, on the other hand, the object conforms to the nature of our faculty of intuition, I can then easily conceive the possibility of such an a priori knowledge.

[T]he first characteristic of the human species is man's ability, as a rational being, to establish character for himself, as well as for the society into which nature has placed him. This ability, however, presupposes an already favorable natural predisposition and an inclination to the good in man, because the evil is really without character (since it is at odds with itself, and since it does not tolerate any lasting principle within itself)
