Philosophy as practice does not mean its restriction to utility or applicability, that is, to what serves morality or produces serenity of soul.

Only then, approaching my fortieth birthday, I made philosophy my life's work.

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

The Greek word for philosopher (philosophos) connotes a distinction from sophos. It signifies the lover of wisdom (knowledge) as distinguished from him who considers himself wise in the possession of knowledge. This meaning of the word still endures: 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.

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.
