Suicide was praised in Greco-Latin Antiquity as a gesture of honor (better a dignified death than an infamous life) before being condemned by religions or being seen as a pathology by psychiatry. Simon Critchley goes through stories of suicides, from Seneca to Kurt Cobain, without judgment, and dismantles the moral and theological arguments according to which an individual does not have the right to dispose of his life. But conversely he criticizes the individualism which claims that each is the exclusive owner of himself. Simon Critchley builds his reflection on the letters left by the disappeared, which make suicide an address to others and force us to question the meaning of all life.
