The ‘doctrine of double effect’ claims that it is in some sense morally less problematic to bring about a negatively evaluated state of affairs as a ‘side effect’ of one’s pursuit of another, morally unobjectionable aim than it is to bring it about in order to achieve that aim. In a first step, this chapter discusses the descriptive difference on which the claim is built. That difference is shown to derive from the attitudinal distinction between intention and ‘acceptance’, a distinction that is in turn claimed to ground in a feature of the decisions that generate the attitudes in question. The resulting analysis is then plugged into two different normative principles that may each be thought to specify the intuitions behind the doctrine of double effect, but which have frequently been conflated. The first concerns the permissibility of bringing about the merely accepted state of affairs, the second its reduced attributability. It is argued that examination of the intuitions behind the two principles supports neither version of the doctrine. Rather, the intuitions are best captured in an attribution principle based on subjective probabilities and a principle of attitude evaluation, neither of which make explicit reference to the attitude of intending.

The U.S. Supreme Court's majorityopinion in Vacco v. Quill assumes thatthe principle of double effect explains thepermissibility of hastening death in thecontext of ordinary palliative care and inextraordinary cases in which painkilling drugshave failed to relieve especially intractablesuffering and terminal sedation has beenadopted as a last resort. The traditionaldoctrine of double effect, understood asproviding a prohibition on instrumental harmingas opposed to incidental harming or harming asa side effect, must be distinguished from otherways in which the claim that a result is notintended might be offered as part of ajustification for it. Although double effectmight appropriately be invoked as a constrainton ordinary palliative care, it is not clearthat it can be coherently extended to justifysuch practices as terminal sedation. A betterapproach would reconsider double effect'straditional prohibition on hastening death as ameans to relieve suffering in the context ofacute palliative care.

Paul Ramsey has argued that the rule of double effect is morally significant because of the existence of indeterminate choices between incommensurable values. I interpret his argument as the following disjunctive syllogism. There are two sorts of principles we can appeal to in dealing with indeterminate choices: the rule of double effect and a commensurate reason principle. The second does not work, so we are left with the first. I respond, first, that this argument commits the fallacy of bifurcation and second, that for all Ramsey has shown, and surprisingly, a commensurate reason principle can deal with indeterminate choices.

T. A. Cavanaugh defends double-effect reasoning (DER), also known as the principle of double effect. DER plays a role in anti-consequentialist ethics (such as deontology), in hard cases in which one cannot realize a good without also causing a foreseen, but not intended, bad effect (for example, killing non-combatants when bombing a military target). This study is the first book-length account of the history and issues surrounding this controversial approach to hard cases. It will be indispensable in theoretical ethics, applied ethics (especially medical and military), and moral theology. It will also interest legal and public policy scholars.

The Doctrine of Double Effect and the Principle of Do No Harm raise important theoretical and practical issues, some of which are discussed by Boyle, Donagan, and Quinn. I argue that neither principle is correct, and some revisionist, and probably nonabsolutist, analysis of constraints on action and omission is necessary. In making these points, I examine several approaches to deflection of threat cases, discuss an argument for the permissibility of voluntary euthanasia, and present arguments relevant to medical contexts which justify intentionally hanning some to aid others, with and without the consent of those harmed.

Recent discussions of the doctrine of double effect have contained improved versions of the doctrine not subject to some of the difficulties of earlier versions. There is no longer one doctrine of double effect. This essay evaluates four versions of the doctrine: two formulations of the traditional Catholic doctrine, Joseph Boyle's revision of that doctrine, and Warren Quinn's version of the doctrine. I conclude that all of these versions are flawed. Keywords: double effect, intention, Joseph Boyle, medical ethics, Warren Quinn CiteULike Connotea Del.icio.us What's this?

Joseph Boyle raises important questions about the place of the double-effect exception in absolutist moral theories. His own absolutist theory (held by many, but not all, Catholic moralists), which derives from the principles that fundamental human goods may not be intentionally violated, cannot dispense with such exceptions, although he rightly rejects some widely held views about what they are. By contrast, Kantian absolutist theory, which derives from the principle that lawful freedom must not be violated, has a corollary – that it is a duty, where possible, to coerce those who try to violate lawful freedom – which makes superfluous many of the double-effect exceptions Boyle allows. Other implications of the two theories are contrasted. Inter alia , it is argued that, in Boyle's theory, that a violation of a fundamental human good can be viewed as a cost proportionate to a benefit obtained, cannot yield a double-effect exception to the prohibition of intentionally violating that good, because paying a cost cannot be unintentional.

The doctrine of double effect continues to be an important tool in bioethical casuistry. Its role within the Catholic moral tradition continues, and there is considerable interest in it by contemporary moral philosophers. But problems of justification and correct application remain. I argue that if the traditional Catholic conviction that there are exceptionless norms prohibiting inflicting some kinds of harms on people is correct, then double effect is justified and necessary. The objection that double effect is superfluous is a rejection of that normative conviction, not a refutation of double effect itself. This justification suggests the correct way of applying double effect to controversial cases. But versions of double effect which dispense with the absolutism of the Catholic tradition lack justification and fall to the objection that double effect is an unnecessary complication.
