What Is It to Commit Suicide?

In this article I defend a new definition of what it is to commit suicide: (D) A commits suicide by performing an act x if and only if A intends that he or she kill himself or herself by performing x (under the description ‘I kill myself’), and this intention is fully satisfied. The definition has some surprising implications: various real‐life examples often referred to as ‘suicides’ (e.g. ‘suicide bombers’) may well turn out not to be suicides after all. 1
