"I have noticed that when these men (certain disciples of A. E.) take to any kind of action it is to some kind of extreme politics. Partly, I think, because they have never learned the discipline which enables the most ardent nature to accept obtainable things, even if a little sadly; but still more because they cannot believe in any success that is not in the unconditioned future, and because, like an artist described by Balzac, they long for popularity that they may believe in themselves."
