There are two men in Tolstoy. He is a mystic and he is also a realist. He is addicted to the practice of a pietism that for all its sincerity is nothing if not vague and sentimental; and he is the most acute and dispassionate of observers, the most profound and earnest student of character and emotion.
The genius of the Spanish people is exquisitely subtle, without being at all acute; hence there is so much humour and so little wit in their literature.
If some really acute observer made as much of egotism as Freud has made of sex, people would forget a good deal about sex and find the explanation for everything in egotism.
If the egotist is weak, his egotism is worthless. If the egotist is strong, acute, full of distinctive character, his egotism is precious, and remains a possession of the race.
