 One initial challenge to the possibility of rational suicide rests on the notion that suicide, being a choice to end one’s life, is necessarily irrational. The thought here is that any coherent judgment of suicide’s rationality requires comparing the state of being alive (or continuing to live) with being dead. But either because no one has sufficient knowledge of the state of being dead (Devine 1978) or because suicide ensures that the suicidal person has no future to look forward to (Cowley 2006), judgments that ending one’s life is rational are incoherent or misplaced.
