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.

Minimal responsibility threateners are epistemically justified but mistaken in thinking that imposing a nonnegligible risk on others is permissible. On standard accounts, an MRT forfeits her right not to be defensively killed. I propose an alternative account: an MRT is liable only to the degree of harm equivalent to what she risks causing multiplied by her degree of responsibility. Harm imposed on the MRT above that amount is justified as a lesser evil, relative to allowing the MRT to kill her (...) victim. This hybrid account, which generalizes to those are who are more than minimally responsible, has considerable advantages. (shrink)

Most people believe that it is sometimes morally permissible for a person to use force to defend herself or others against harm. In Defensive Killing, Helen Frowe offers a detailed exploration of when and why the use of such force is permissible. She begins by considering the use of force between individuals, investigating both the circumstances under which an attacker forfeits her right not to be harmed, and the distinct question of when it is all-things-considered permissible to use force against (...) an attacker. Frowe then extends this enquiry to war, defending the view that we should judge the ethics of killing in war by the moral rules that govern killing between individuals. She argues that this requires us to significantly revise our understanding of the moral status of non-combatants in war. Non-combatants who intentionally contribute to an unjust war forfeit their rights not to be harmed, such that they are morally liable to attack by combatants fighting a just war. (shrink)

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.

One of the reasons why most of us feel puzzled about the problem of abortion is that we want, and do not want, to allow to the unborn child the rights that belong to adults and children. When we think of a baby about to be born it seems absurd to think that the next few minutes or even hours could make so radical a difference to its status; yet as we go back in the life of the fetus we (...) are more and more reluctant to say that this is a human being and must be treated as such. No doubt this is the deepest source of our dilemma, but it is not the only one. For we are also confused about the general question of what we may and may not do where the interests of human beings conflict. We have strong intuitions about certain cases; saying, for instance, that it is all right to raise the level of education in our country, though statistics allow us to predict that a rise in the suicide rate will follow, while it is not all right to kill the feeble-minded to aid cancer research. It is not easy, however, to see the principles involved, and one way of throwing light on the abortion issue will be by setting up parallels involving adults or children once born. So we will be able to isolate the “equal rights” issue and should be able to make some advance... (shrink)

In Intricate Ethics, Kamm questions the moral importance of some non-consequentialist distinctions and then introduces and argues for the moral importance of ...

I defend the doctrine of double effect and a so-called ‘strict’ definition of intention: A intends an effect if and only if A has it as an end or believes that it is a state of affairs in the causal sequence that will result in A's end. Following Kamm's proposed ‘doctrine of triple effect’, I distinguish an intended effect from an effect that motivates an action, and show that this distinction is morally significant. I use several contrived cases as illustrations, (...) but my position does not depend on intuitive judgements about them. Instead, it follows from the view that the moral permissibility of an action depends at least partly on how it forms the agent's character. I also respond to some objections presented by Harris, Bennett, McIntyre, Thomson and Scanlon to the doctrine of double effect. (shrink)

There may be circumstances in which it is morally justifiable intentionally to kill a person who is morally innocent, threatens no one, rationally wishes not to die, and does not consent to be killed. Although the killing would wrong the victim, it might be justified by the necessity of averting some disaster that would otherwise occur. In other instances of permissible killing, however, the justification appeals to more than consequences. It may appeal to the claim that the person to be (...) killed has acted in such a way that to kill him would neither wrong him nor violate his rights, even if he has not consented to be killed or to be subjected to the risk of being killed. In these cases, I will say that the person is liable to be killed. Although I borrow the notion of liability from legal theory, and although much of what I say will be informed by the literature on liability in both tort law and criminal law, my concern in this article is with moral rather than legal liability.

This comment asks us to imagine that we have discovered a principle that completely matches our intuitions about the various actions that might be performed in all the different versions of the trolley problem. Would that constitute a solution to the problem of providing a plausible principle to cover these various cases? Not necessarily, since the principle might turn on distinctions that have no obvious moral significance, and we might be unable to provide the principle with a compelling and plausible (...) rationale. It argues that this might well be the situation we find ourselves in with regard to the book’s proposed solution to the trolley problem: even if the principle does match our intuitions in how it sorts the cases, it is difficult to see why the distinctions on which it turns should matter, and appearances to the contrary notwithstanding, this comment believes the book has not provided the principle with a plausible account or rationale.

In this article, I develop a general explanatory model of the liability and lesser evil justifications of harm. Despite their respective provenance in consequentialist and deontological ethics, both justifications are, at root, rich forms of the proportionality relationship between a shared set of underlying normative variables. The nature of the proportionality relationship, and the conditions under which it operates, differ between the two forms of justification. The article explores these differences in detail and the implications they have for the justification (...) of self-defense and war. (shrink)

I try to show that agent responsibility is an inadequate basis for the attribution of liability, by discrediting the Risk Argument and showing how the Responsibility Argument in fact collapses into the Risk Argument. I have concentrated on undermining these as philosophical theories of self-defense, although I at times note that our theory of self-defense should not be predicated on assumptions that are inapplicable to the context of war. The potential combatant, I conclude, should not look to the agency view (...) to ease his conscience about the killing he will do in war. If he is to fight without violating rights, then he will need a different theory of self-defense; if there are no more defensible theories, then he must either accept pacifism—which I think is a live possibility—or seek to identify stronger countervailing reasons, which can override the great force of his victims’ rights to life.

On Jeff McMahan's influential ‘responsibility account’ of moral liability to defensive killing, one can forfeit one's right not be killed by engaging in an ordinary, morally permissible risk-imposing activity, such as driving a car. If, through no fault of hers, a driver's car veers out of control and toward a pedestrian, the account deems it no violation of the driver's right to save the pedestrian's life at the expense of the driver's life. Many critics reject the responsibility account on the (...) grounds that, first, it has draconian implications for threateners like the driver, and second, it contravenes the plausible principle that wronging one's victim is necessary for forfeiting one's rights. But I argue, drawing on the account's luck-egalitarian underpinnings, that the account lacks the draconian implications widely attributed to it, and contrary to what many assume, wrongdoing is unnecessary for rights-forfeiture. Via these arguments, I seek both to deepen our understanding of the responsibility account, and to reissue it in a more plausible and attractive form. (shrink)

This chapter analyses making/allowing in terms of positive/negative: you allow something to happen if an explanation of its happening requires only a negative fact about your behaviour. A negative fact about your behaviour is a highly general or uninformative one; it corresponds to almost the whole of the logical space of your possible ways of moving. An objection to this analysis, based on giving a very special status to immobility, is described and countered. The possibility space might have a different (...) metric, i.e. be structured in terms of something other than possible ways of moving. One such alternative metric is discussed. (shrink)

This book offers a critical examination of those theories and advances a new argument for punishment's justification, calling it the 'duty view'.

This essay defends a version of the Doctrine of Double Effect (DDE) – the doctrine that there is normally a stronger reason against an act that has a bad state of affairs as one of its intended effects than against an otherwise similar act that has that bad state of affairs as an unintended effect. First, a precise account of this version of the DDE is given. Secondly, some suggestions are made about why we should believe the DDE, and about (...) why it is true. Finally, a solution is developed to the so-called ‘closeness problem’ that any version of the DDE must face. (shrink)

The distinction between harm that is intended as a means or end, and harm that is merely a foreseen side-effect of one’s action, is widely cited as a significant factor in a variety of ethical contexts. Many use it, for example, to distinguish terrorist acts from certain acts of war that may have similar results as side-effects. Yet Bennett and others have argued that its application is so arbitrary that if it can be used to cast certain harmful actions in (...) a more favorable light, then it can equally be manipulated to do the same for any kind of harmful action. In response, some have tried to block such extensions of the intend/foresee distinction by rejecting its application in cases where the relation between the plainly intended means and the harm is “too close”. This move, however, has been attacked as vague and obscure, and Bennett has argued that all the plausible candidates for explicating the idea of excessive closeness ultimately fail. In this paper, I develop and defend an account of excessive closeness with the aim of rescuing the intend/foresee distinction from such charges of arbitrariness. The account is based on the distinction between merely causal and constitutive relations among states of affairs, and I show both how it escapes Bennett’s objections to other accounts and how it applies to a variety of cases. Finally, I also examine Quinn’s alternative move of shifting the focus of the intend/foresee distinction in an attempt to sidestep the issue of closeness, and argue that it is not ultimately successful. In fact, Quinn’s view has shortcomings that can be resolved only by returning to an appeal to some notion of closeness, underscoring the need for the sort of account I offer. (shrink)

T. A. Cavanaugh defends double-effect reasoning, also known as the principle of double effect. DER plays a role in anti-consequentialist ethics, in hard cases in which one cannot realize a good without also causing a foreseen, but not intended, bad effect. 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, and moral theology. It will also interest legal and public policy scholars.

The constraint against harming people in order to save yourself and others seems stronger than the constraint against harming people as a consequence of saving yourself and others. The reduced constraint against acting in one type of case is often justified with reference to the intentions of the agent or to the fact that she does not use the people she harms as a means. In this article I offer a victim-centered account. I argue that the circumstances in which the (...) people to be harmed find themselves are significant in distinguishing morally between two instances of harming. (shrink)

This comment discusses the book's positive account of the trolley problem, given in the Principle of Permissible Harm. This principle says an act that causes both a greater good and a lesser evil is impermissible if the evil results from a means to the good but can be permissible if the evil results from the good itself or from its noncausal flip side. This comment argues that this principle has counterintuitive implications—for example, that bombing an arms factory that kills nearby (...) civilians is impermissible if the civilians are killed by flying pieces of bomb but permissible if they are killed by flying pieces of factory. It then argues that the principle lacks a persuasive philosophical rationale because it draws an arbitrary line in a sequence of means to an end and trades on an ambiguity in its understanding of “the greater good.”.
