“As a fact, there is no shred of evidence to show that those who have had sad experiences tend to have a sad philosophy. There are numberless points upon which Dickens is spiritually at one with the poor, that is, with the great mass of mankind. But there is no point in which he is more perfectly at one with them than in showing that there is no kind of connection between a man being unhappy and a man being pessimistic. Sorrow and pessimism are indeed, in a sense, opposite things, since sorrow is founded on the value of something, and pessimism upon the value of nothing.”
