In the foreground, the practical world; then, thought itself. Ties, shackles everywhere. A very limited field of action and a role to fulfill, by necessity. Wherever reasoning directs its lens, there are the claws of convenience. And none of this frightens, all of this is nothing but normality. A few—madmen—awaken, however. They manifest themselves through revolt. To them, due to blasphemy, all the ferocity with which an animal reacts when it feels threatened. And there remains rebellion, therefore, inadvisable—for those who follow advice. And for the few, the happiness of knowing they are not the majority. As Fernando Savater said, it is necessary the vocation of freedom to recognize oneself as a slave.
