Abstract

In this paper I describe cases of moral blackmail as cases where A is told by B that if A does not commit an otherwise immoral act, B will commit an immoral act of equal or greater gravity. I describe cases of moral dilemma as cases where A must commit an otherwise immoral act to avert a natural disaster of equal or greater gravity. I then argue that cases of moral blackmail are structurally identical to cases of moral dilemma in all respects but one: In cases of moral blackmail, A is predicting the free actions of a moral agent (B), whereas in cases of moral dilemma, A is predicting natural events. I conclude that cases of moral blackmail are more problematic than otherwise similar cases of moral dilemma for this reason alone.
