The doctrine of double effect, together with other moral principles that appeal to the intentions of moral agents, has come under attack from many directions in recent years, as have a variety of rationales that have been given in favor of it. In this paper, our aim is to develop, defend, and provide a new theoretical rationale for a secular version of the doctrine. Following Quinn (1989), we distinguish between Harmful Direct Agency and Harmful Indirect Agency. We propose the following (...) version of the doctrine: that in cases in which harm must come to some in order to achieve a good (and is the least costly of possible harms necessary), the agent foresees the harm, and all other things are equal, a stronger case is needed to justify Harmful Direct Agency than to justify Harmful Indirect Agency. We distinguish between two Kantian rationales that might be given for the doctrine, a “dependent right” rationale, defended by Quinn, and an “independent right” rationale, which we defend. We argue that the doctrine and the “independent right” rationale for it are not vulnerable to counterexamples or counterproposals, and conclude by drawing implications for the larger debate over whether agents' intentions are in any way relevant to permissibility and obligation.

According to the classical Doctrine of Double Effect, there is a morally significant difference between intending harm and merely foreseeing harm. Versions of DDE have been defended in a variety of creative ways, but there is one difficulty, the so-called “closeness problem”, that continues to bedevil all of them. The problem is that an agent's intention can always be identified in such a fine-grained way as to eliminate an intention to harm from almost any situation, including those that have been (...) taken to be paradigmatic instances in which DDE applies to intended harm. In this paper, we consider and reject a number of recent attempts to solve the closeness problem. We argue that the failure of these proposals strongly suggests that the closeness problem is intractable, and that the distinction between intending harm and merely foreseeing harm is not morally significant. Further, we argue that there may be a deeper reason why such attempts must fail: the rationale that makes the best fit with DDE, namely, an imperative not to aim at evil, is itself irredeemably flawed. While we believe that these observations should lead us to abandon further attempts to solve the closeness problem for DDE, we also conclude by showing how a related principle that is supported by a distinct rationale and avoids facing the closeness problem altogether nevertheless shares with DDE its most important features, including an intuitive explanation of a number of cases and a commitment to the relevance of intentions.

The Doctrine of Double Effect (DDE) is an influential non-consequentialist principle positing a role for intention in affecting the moral permissibility of some actions. In particular, the DDE focuses on the intend/foresee distinction, the core claim being that it is sometimes permissible to bring about as a foreseen but unintended side-effect of one’s action some harm it would have been impermissible to aim at as a means or as an end, all else being equal. This article explores the meaning and (...) application of the DDE along with current debates over the nature of the intend/foresee distinction and its moral significance. How is the line between intended effects and merely foreseen but unintended side-effects to be drawn, and how are problem cases best handled? What is an appropriate methodology for debating the tenability of the DDE? How might the DDE interact with other non-consequentialist principles, and how might it be modified to capture other related factors (resulting perhaps in a Doctrine of Triple Effect) or to avoid certain problem cases? Does the DDE make permissibility turn on the actual intentions of particular agents, as critics such as Thomson and Scanlon assume, or is the role of intention more abstract? (shrink)

Based on the results of empirical studies of folk moral judgment, several researchers have claimed that something like the famous Doctrine of Double Effect may be a fundamental, albeit unconscious, component of human moral psychology. Proponents of this psychological DDE hypothesis have, however, said surprisingly little about how the distinction at the heart of standard formulations of the principle—the distinction between intended and merely foreseen consequences—might be cognised when we make moral judgments about people’s actions. I first highlight the problem (...) of precisely formulating the distinction between intended and foreseen consequences and its implications for interpreting the empirical data on folk moral judgment. I then distinguish between three different approaches to this problem that have been taken by proponents of the DDE in normative ethics: so-called “closeness” accounts, accounts that employ what has come to be known as a “strict” notion of intention, and Warren Quinn’s recasting of the DDE in terms of the distinction between “direct” and “indirect agency”. I show that when taken as claims about moral psychology, these different accounts entail quite different empirical predictions about what people’s moral judgments should be in particular cases. Based on the current empirical data, I argue that a version of Quinn’s formulation of the DDE is the most empirically plausible, and that adopting such a formulation helps to diffuse much of the recent empirical criticism of the DDE hypothesis.
