“L’arte de vivere è l’arte di saper credere alle menzogne” —says, rightly, Cesare Pavese. To act, it is necessary to believe; there is no life without hope, without at least a tiny expectation, a minimum twinkle in the eyes that, upon waking, hopes for a better today than yesterday. Man allows himself to be deluded by psychological necessity; illusions are food for a mind programmed to believe. This is why the analysis of the human being necessarily involves the investigation of the irrational.
