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.
