Like the character Moliere who discovered to his astonishment that he had been speaking prose all his life, I discovered to my astonishment that I had been immersed in philosophical problems all my life. And I had been drawn into the same problems as great philosophers by the same felt need to make sense of the world...The chief difference between me and them, of course, was that whereas they had something to offer by way of solutions to the problems, I had failed even to formulate very rich or sophistocated versions of the problems, let alone work my way through to defensible solutions for them. In consequence I fell on their work like a starving man on food, and it has done a geat deal to nourish and sustain me ever since.
