My principal sin is doubt. I doubt everything, and am in doubt most of the time. - Leo Tolstoy

It's not so much that he can't fall in love, but he has not the weakness necessary.

My life now, my whole life, regardless of all that may happen to me, every minute of it, is not only not meaningless, as it was before, but has the unquestionable meaning of the good which it is in my power to put into it!

But one no longer wonders when one realizes that in the higher classes there is an unerring instinct of what tends to maintain and of what tends to destroy the organization by virtue of which they enjoy their privileges. The fashionable lady had certainly not reasoned out that if there were no capitalists and no army to defend them, her husband would have no fortune, and she could not have her entertainments and her ball-dresses. And the artist certainly does not argue that he needs the capitalists and the troops to defend them, so that they may buy his pictures. But instinct, replacing reason in this instance, guides them unerringly. And it is precisely this instinct which leads all men, with few exceptions, to support all the religious, political, and economic institutions which are to their advantage.
