So here, in these philosophers, was stuff that seemed just as hard as the physics and chemistry that were bringing me to New York. Moreover, philosophers seemed to value a lack of confidence—telling me, not to ignore my doubts and get back to studying, but to push my uncertainty as far as it could go. Sartre explained why this is inescapable—only by self-deception can we hide from ourselves the fact of choice and the depth of our inability to anchor life in external or internal certainties. Like it or not, we were in the end responsible for who we are and what sort of world we inhabit.
