Context: My answer to the question "Why do we philosophize?" is as follows. We philosophize for the same reason that we move and speak and laugh and eat and love. In other words, we philosophize because man is a philosophical animal.… We may be as sceptical as we please. Our very scepticism is the confession of an implicit philosophy.
