艺术的本质功能是道德的。但这是激情、含蓄的道德，不是说教的。这种道德改变的是血液，而不是思想。
The essential function of art is moral. But a passionate, implicit morality, not didactic. A morality which changes the blood, rather than the mind.
"The only way to deal with an unfree world is to become so absolutely free that your very existence is an act of rebellion."
