“Self knowledge is a virtue in its own right. We value the way in which people can fulfill their own natures by gaining an unsentimental self understanding. We think it is good to grow, for all our vices, into someone who is mature enough to face the past and the present, someone who understands how character, in its weaknesses as well as its strengths, is made of interlocking tendencies and gifts that have grown in the course of a life. The image of growth and maturing is Aristotelian rather than Kantian. These ancient values are ideals that none fully achieve, and yet they are modest, not seeking to find a meaning in life, but finding excellence in living and honoring life and its potentialities.”

“Both [Quine and Feyerabend] want to revise a version of positivism. Quine started with the Vienna Circle, and Feyerabend with the Copenhagen school of quantum mechanics. Both the Circle and the school have been called children of Ernst Mach; if so, the philosophies of Feyerabend and Quine must be his grandchildren.”

“The best reaction to a paradox is to invent a genuinely new and deep idea.”
