Isaiah Berlin once said that there are two kinds of writers, hedgehogs and foxes. He said the fox knows many things, the hedgehog knows just one thing. So Shakespeare is a typical fox; Tolstoy and Dostoyevsky are typical hedgehogs. Now, I'm a typical hedgehog. I know just one thing, and I repeat it over and over again. I try to approach it from different angles to make it look different, but it's the same thing.

It seemed perfectly possible that, in spite of my certainty of my own genius, I might die of some illness, or perhaps even in a street accident, before I had ever glimpsed the meaning of life. My moods of happiness and self-confidence convinced me that I had a "destiny" to become a famous writer, and to be remembered as one of the most important thinkers of the century.

Turning on the light is easy if you know where the switch is.
