My thesis explores the possibility that the wrongful intentions principle might not apply in certain deterrent situations. WIP states that if it is wrong to do something under certain conditions, it is wrong to intend to do it should those conditions arise. Questions about applications of WIP are frequently raised in discussions about the morality of nuclear deterrence. Some philosophers, such as Gregory Kavka, maintain that in certain situations where gaining deterrence is important, it is morally permissible, and perhaps even (...) obligatory to form a sincere intention to retaliate although retaliation is wrong. ;The rejection of WIP causes paradoxes about relationships between good agents and right actions. Good and rational agents are unable to fulfill obligations to intend wrong, as their unwillingness to do wrong makes intending it impossible. Hence, the paradoxical conclusion that only a corrupt individual can do right in certain situations. ;The conclusion that in certain situations only corrupt agents can do right rests upon rejecting the WIP. I show that WIP applies in all deterrence situations and in all situations, period. Because WIP always applies, there are no situations where goodness and rationality prevent right action. ;Chapter one presents consequentialist and non-consequentialist arguments to the conclusion that actual retaliation against civilian populations is wrong. In chapters two and three I argue that the kinds of situations discussed by Kavka and others doesn't warrant rejecting WIP. I maintain that non-consequentialist theories cannot permit agents to separate questions about intentions from questions about actions. Consequentialism cannot justify rejecting WIP in these situations either. Rejection of WIP implies that a corrupt leader is needed, and consequentialism cannot justify seeking such a leader. Chapter four argues that WIP must apply in all situations because it must be part of any action-guiding theory, either consequentialist or non-consequentialist. Talk of rejecting WIP is incoherent. Hence, because WIP always applies, goodness and rationality will never preclude right action, and whenever performing an action is wrong, intending to perform it is wrong as well. (shrink)
