Abstract

If you injure me, it matters morally whether it was an accident or you did it intentionally, and whether you did it because you thought it would be fun. I take it that any ethical theory will have to include some explanation of why this is. There are two dominant views in the current debate about the moral significance of an agent’s intentions: The one is that the intention with which someone acts at least sometimes determines whether what she does is right or wrong (permissible or impermissible). Proponents of the so-called doctrine of double-effect (DDE) hold that an action which has certain bad outcomes may be permissible if the bad consequences are only foreseen, even if the same action would be morally wrong if they were intended as a means. This is not the only way in which intentions could make a difference to an action’s permissibility, but it is the best-known defense that they do. According to the second view, intentions don’t matter in this way: they do not determine the permissibility of an action. They do matter, but in a different dimension of normative assessment: They determine whether the agent is a good or a bad person; or alternatively: they determine the “moral worth” of an action or its “meaning”, including its praiseworthiness or blameworthiness , or the severity of a wrong-doing. The main thesis is what Thomson called “The Irrelevance-of-Intentions-to-Permissibility Thesis” (for short: IIP) [IIP] “It is irrelevant to the question whether X may do alpha what intention X would do alpha with if he or she did it.” IIP is driven in part by skepticism about DDE: since – according to proponents of IIP - DDE is false, we must explain the relevance of intentions and reasons in a different way. Proponents of IIP tend not to consider the possibility that intentions might matter to permissibility in ways that are different from DDE. In this paper I do not focus on the arguments for or against DDE, but investigate IIP itself more closely, and look at some of the arguments for and against it.
