good novel rushes you forward like a skiff down a stream, and you arrive at the end, perhaps breathless, but unexhausted. The best novels involve the least strain. Now in the cultivation of the mind one of the most important factors is precisely the feeling of strain, of difficulty, of a task which one part of you is anxious to achieve and another part of you is anxious to shirk; and that feeling cannot be got in facing a novel. You do not set your teeth in order to read “Anna Karenina.” Therefore, though you should read novels, you should not read them in those ninety minutes.
