“Unfortunately, moral beauty in art -- like physical beauty in a person -- is extremely perishable. It is nowhere so durable as artistic or intellectual beauty. Moral beauty has a tendency to decay very rapidly into sententiousness or untimeliness.”
“There are few things more disturbing than to find, in somebody we detest, a moral quality which seems to us demonstrably superior to anything we ourselves possess. It augurs not merely an unfairness on the part of creation, but a lack of artistic judgment. Sainthood is acceptable only in saints.”
“He that has not religion to govern his morality, is not a dram better than my mastiff-dog; so long as you stroke him, and please him, and do not pinch him, he will play with you as finely as may be, he is a very good moral mastiff; but if you hurt him, he will fly in your face, and tear out your throat.”
“When we start deceiving ourselves into thinking not that we want something or need something, not that it is a pragmatic necessity for us to have it, but that it is a moral imperative that we have it, then is when we join the fashionable madmen, and then is when the thin whine of hysteria is heard in the land, and then is when we are in bad trouble.”
“For the ''superior morality,'' of which we hear so much, we too would desire to be thankful: at the same time, it were but blindness to deny that this ''superior morality'' is properly rather an ''inferior criminality,'' produced not by greater love of Virtue, but by greater perfection of Police; and of that far subtler and stronger Police, called Public Opinion.”
“The great rule of moral conduct is next to God, respect time.”
“Do not be too moral. You may cheat yourself out of much life. So aim above morality. Be not simply good; be good for something.”
