“We must not try to change within ourselves or to efface desires and aversions, pleasures and sorrows. We must submit to them passively, just as we do the impressions we receive from colors, according them no greater credit to them than in the latter case. ... We must compel ourselves by violence to act as though we had not a certain desire or aversion, without trying to persuade our sensibility—compelling it to obey. This causes it to revolt and we have to endure this revolt passively, taste of it, savor it, accept it as something outside ourselves, as the pink color of the room with the red window. ... Each time we do violence to ourselves in this spirit we make an advance, slight or great but real, in the work of training the animal within us.”
