My Autobiography by Charlie Chaplin:
As usual I lived alone. But it had its advantages, because it gave me an opportunity to improve my mind, a resolution I had held for many months but never fulfilled.
There is a fraternity of those who passionately want to know. I was one of them. But my motives were not so pure; I wanted to know, not for the love of knowledge but as a defence against the world’s contempt for the ignorant. So when I had time I browsed around the second-hand bookshops.
