Dare to know! Have the courage to use your own intelligence!

Enlightenment is man's emergence from his self-incurred immaturity.

The main point of enlightenment is man's release from his self-caused immaturity, primarily in matters of religion.

Act so as to treat humanity, whether in your own person or in that of another, at all times also as an end, and not only as a means.

Without sensibility no object would be given to us, without understanding no object would be thought. Thoughts without content are empty, intuitions without concepts are blind. It is, therefore, just as necessary to make our concepts sensible, that is, to add the object to them in intuition, as to make our intuitions intelligible, that is, to bring them under concepts. These two powers or capacities cannot exchange their functions. The understanding can intuit nothing, the senses can think nothing. Only through their union can knowledge arise. But that is no reason for confounding the contribution of either with that of the other; rather is it a strong reason for carefully separating and distinguishing the one from the other. We therefore distinguish the science of the rules of sensibility in general, that is, aesthetic, from the science of the rules of the understanding in general, that is, logic.
