"No revolution, no heresy, is comfortable and easy. Because it is a leap, it is a rupture of the smooth evolutionary curve and a rupture is a wound, a pain. But it is a necessary wound: most people suffer from hereditary sleeping sickness, and those who are sick with this ailment (entropy) must not be allowed to sleep or they will go to their last sleep, the sleep of death.
This same sickness is common to artists and writers: they go contentedly to sleep in their favorite artistic form which they have devised, then twice revised. They do not have the strength to wound themselves, to cease to love what has become dear to them. They do not have the strength to come out from their lived-in, laurel-scented rooms, to come out into the open air and start anew. To wound oneself, it is true, is difficult, even dangerous. But to live today as yesterday and yesterday as today is more difficult for the living."
