... a slim volume of philosophy.

I should have listened to the advice I had been given by Tom Maschler, then one of the most successful publishers in London. If I wanted to be taken seriously as an author, he told me, I should write a long book. I objected that I didn’t think I could write a very good long book. Whether it was good or not was beside the point, he said, provided it was long.
