If philosophy is to be a valuable part of life, we have to appreciate it for its own sake, and not just for what it's done for us lately.

Philosophy has to be enquiring; it can take nothing on faith, and its methods are based not on the blind acceptance of authority, but on establishing truths by reason and argument.

Philosophy is at its most engaged when it is impure. What is being recovered from the Ancient Greek model is not some lost idea of philosophy's pure essence, but the idea that philosophy is mixed up with everything else.
