Albert Camus, in his otherwise hopelessly outdated The Myth of Sisyphus, is right to emphasize that suicide is the only real philosophical problem — when, however, does it become so? Only in modern reflexive society, when life itself no longer ‘goes by itself”, as a ‘non-marked’ feature (to use the term developed by Roman Jakobson), but is ‘marked’, has to be especially motivated (which is why euthanasia is becoming acceptable). Prior to modernity, suicide was simply a sign of some pathological malfunction, despair, misery. With reflexivization, however, suicide becomes an existential act, the outcome of a pure decision, irreducible to objective suffering or psychic pathology. This is the other side of Emile Durkheim’s reduction of suicide to a social fact that can be quantified and predicted: the two moves, the objectivization/quantification of suicide and its transformation into a pure existential act, are strictly correlative.
