"With the advent of medieval Scholasticism, … we find a clear distinction between theologia and philosophia. Theology became conscious of its autonomy qua supreme science, which philosophy was emptied of its spiritual exercises, which, from now on, were relegated to Christian mysticism and ethics. Reduced to the rank of a “handmaid of theology,” philosophy’s role was henceforth to furnish theology with conceptual—and hence purely theoretical—material. When, in the modern age, philosophy regained its autonomy, it still retained many features inherited from this medieval conception. In particular, it maintained its purely theoretical character, which even evolved in the direction of a more and more thorough systemization. Not until Nietzsche, Bergson, and existentialism does philosophy consciously return to being a concrete attitude, a way of life and of seeing the world."

“Philosophy—reduced, as we have seen, to philosophical discourse—develops from this point on in a different atmosphere and environment from that of ancient philosophy. In modern university philosophy, philosophy is obviously no longer a way of life, or a form of life—unless it be the form of life of a professor of philosophy.”

“One could say that what differentiates ancient from modern philosophy is the fact that, in ancient philosophy, it was not only Chrysippus or Epicurus who, just because they had developed a philosophical discourse, were considered philosophers. Rather, every person who lived according to the precepts of Chrysippus or Epicurus was every bit as much a philosopher as they.”

“Socrates had no system to teach. Throughout, his philosophy was a spiritual exercise, an invitation to a new way of life, active reflection, and living consciousness.”

“Socrates splits himself into two, so that there are two Socrates: the Socrates who knows in advance how the discussion is going to end, and the Socrates who travels the entire dialectical path along with his interlocutor.”

“There was a Socratic style of life , and the Socratic dialogue was an exercise which brought Socrates’ interlocutor to put himself in question, to take care of himself, and to make his soul as beautiful and wise as possible.”

“To know oneself means, among other things, to know oneself qua non-sage: that is, not as a sophos, but as a philo-sophos, someone on the way toward wisdom.”
