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

Only as an individual can man become a philosopher.

As a universal history of philosophy, the history of philosophy must become one great unity.

I discovered that the study of past philosophers is of little use unless our own reality enters into it. Our reality alone allows the thinker's questions to become comprehensible.

Reason is like an open secret that can become known to anyone at any time; it is the quiet space into which everyone can enter through his own thought.

The study of law left me unsatisfied, because I did not know the aspects of life which it serves. I perceived only the intricate mental juggling with fictions that did not interest me.
