Cynicism is a school of Greek philosophers, founded by a disciple of Socrates, Antisthenes.
Diogenes the Dog is the most important thinker of this current.
The school is characterized by a cynical disregard of social conventions and a cult of virtue, especially deprived (Diogenes lived in a barrel). It has often been retained only the critical face of cynicism, forgetting that it is the positive, especially on moral asceticism.
