The science of mathematics presents the most brilliant example of how pure reason may successfully enlarge its domain without the aid of experience.

A Quote by Immanuel Kant on animals, cruelty, heart, judgment, and men

He who is cruel to animals becomes hard also in his dealings with men. We can judge the heart of a man by his treatment of animals.

A Quote by Immanuel Kant on certainty, intuition, and thought

All thought must, directly or indirectly, by way of certain characters, relate ultimately to intuitions, and therefore, with us, to sensibility, because in no other way can an object be given to us.

A Quote by Immanuel Kant on action, duty, interest, joy, kindness, maxims, motives, pleasure, satisfaction, self-interest, vanity, work, and worth

To be beneficent when we can is a duty; and besides this, there are many minds so sympathetically constituted that, without any other motive of vanity or self-interest, they find a pleasure in spreading joy around them, and can take delight in the satisfaction of others so far as it is their own work. But I maintain that in such a case an action of this kind, however proper, however amiable it may be, has nevertheless no true moral worth, but is on a level with other inclinations. . . . For the maxim lacks the moral import, namely, that such actions be done from duty, not from inclination.

A Quote by Immanuel Kant on atheism, criticism, danger, fanaticism, idealism, schools, skepticism, superstition, and thinking

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.
