All democracies demand common public education because nothing makes people so much alike as the same education.

the essence of philosophy is not the possession of the truth but the search for truth. ... Philosophy means to be on the way. Its questions are more essential than its answers, and every answer becomes a new question.

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

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

Everything depends therefore on encountering thought at its source. Such thought is the reality of man's being, which achieved consciousness and understanding of itself through it.

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.

Only a development of thought achieved through the self-education of the whole man can prevent any body of thought whatsoever from becoming a poison; can prevent enlightenment from becoming an agent of death.
