Philosophy can only be approached with the most concrete comprehension.

At the present moment, the security of coherent philosophy, which existed from Parmenides to Hegel, is lost.

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.

The moment is the sole reality.

My own being can be judged by the depths I reach in making these historical origins my own.

To decide to become a philosopher seemed as foolish to me as to decide to become a poet.

When language is used without true significance, it loses its purpose as a means of communication and becomes an end in itself.
