Man is always something more than what he knows of himself. He is not what he is simply once and for all, but is a process; he is not merely an extant life, but is, within that life, endowed with possibilities through the freedom he possesses to make of himself what he will by the activities on which he decides.

Philosophy is tested and characterised by the way in which it appropriates its history.

If philosophy is practice, a demand to know the manner in which its history is to be studied is entailed: a theoretical attitude toward it becomes real only in the living appropriation of its contents from the texts.

We must learn to talk with each other, and we mutually must understand and accept one another in our extraordinary differences.

Only as an individual can man become a philosopher.
