A strong tradition in philosophy denies the possibility of moral dilemmas. Recently, several philosophers reversed this tradition. In this dissertation, I clarify some fundamental issues in this debate, argue for the possibility of moral dilemmas, and determine some implications of this possibility. ;In chapter I, I define moral dilemmas roughly as situations where an agent morally ought to adopt each of two alternatives but cannot adopt both. Moral dilemmas are resolvable if and only if one of the moral oughts overrides (...) the other. ;In chapter II, I criticize several opponents of moral dilemmas, including utilitarians, Kant, Aquinas, and Ross. My main criticism is that no opponent of moral dilemmas can adequately justify moral residue . ;Chapters III and IV concern the two main arguments against the possibility of moral dilemmas. First, the argument for 'ought' implies 'can' runs as follows. If the agent cannot adopt both, then it is not the case that the agent ought to adopt both. But the agent ought to adopt both, since the agent ought to adopt each . Thus, the defining judgements of a moral dilemma seem to imply a contradiction. In response, I argue that the relation between 'ought' and 'can' is not a logical implication but a conversational implicature. ;Chapter IV concerns the argument from 'ought' implies 'permitted': If the agent ought to adopt one alternative, then the agent is permitted to adopt that alternative, which means that it is not the case that the agent ought not to adopt that alternative. But the agent ought not to adopt that alternative, since the agent ought to adopt the other alternative and cannot adopt both. I respond that 'ought' does not logically imply but conversationally implicates 'permitted'. ;In chapter V, I argue that, despite recent claims, both moral realism and anti-realism are compatible with the possibility of moral dilemmas. Thus, there are several reasons to accept and no reasons to deny the possibility of moral dilemmas. (shrink)

A moral dilemma is a situation in which an agent ought to do each of two actions, Both of which he cannot do. If there are genuine moral dilemmas, The ethical theorist is presented with a problem: he must reject several very plausible principles of standard deontic logic. The main reasons usually given to show that there are moral dilemmas are examined, And it is argued that they are not sufficient. Several positive arguments are then presented, Arguments which try to (...) show that an adequate moral theory must rule out the possibility of genuine dilemmas. (shrink)

Altruistic maximizers face a frustrating dilemma when there is an infinite series of ever-better options, but no best choice.

The essays in this volume illuminate a central topic in ethical theory: moral dilemmas. Some contemporary philosophers dispute the traditional view that a true moral dilemma -- a situation in which a person has two irreconcilable moral duties -- cannot exist. This collection provides the historical background to the ongoing debate with selections from Kant, Mill, Bradley, and Ross. The best recent work on the question is represented in essays by Donagan, Foot, Hare, Marcus, Nagel, van Fraassen, Williams, and others.

Cliff Landesman provides a vivid description of a case where we have no best outcome available to us. He poses this as a problem for utilitarians who advise us to do the best we can. This does indeed make such advice impractical. I begin by contrasting older versions of utilitarianism with newer ones that have appeared in deontic logic and that were designed precisely to accommodate Landesman's sort of scenario. (I cast matters in terms of the Limit Assumption and world-theoretic (...) versions of utilitarianism.) I then make three points. First, Landesman's problem does not pose any special problem for these newer theories. Secondly, I note that it is an interesting consequence of these newer theories being utilitarian theories, that--contrary to the tradition--utilitarianism isn't automatically a no conflicts theory of obligation. Thirdly, and most importantly, I identify a new, deeper and wider theoretical problem: "The Confinement Problem". This problem infests the newer versions of utilitarianism. Worse still, the infestation spreads to satisficing consequentialism (cf. Scheffler, Slote), the direction Landesman points to for a solution to his problem, and this new problem is one where the theoretical rulings of these theories clearly conflict with intuition.
