I argue that we should reject all traditional forms of act-consequentialism if moral rationalism is true. (Moral rationalism, as I define it, holds that if S is morally required to perform x, then S has decisive reason, all things considered, to perform x.) I argue that moral rationalism in conjunction with a certain conception of practical reasons (viz., the teleological conception of reasons) compels us to accept act-consequentialism. I give a presumptive argument in favor of moral rationalism. And I argue that act-consequentialism is best construed as a theory that ranks outcomes, not according to their impersonal value, but according to how much reason each agent has to desire that they obtain.

Maximizing act consequentialism holds that actions are morally permissible if and only if they maximize the value of consequences—if and only if, that is, no alternative action in the given choice situation has more valuable consequences.[i] It is subject to two main objections. One is that it fails to recognize that morality imposes certain constraints on how we may promote value. Maximizing act consequentialism fails to recognize, I shall argue, that the ends do not always justify the means. Actions with maximally valuable consequences are not always permissible. The second main objection to maximizing act consequentialism is that it mistakenly holds that morality requires us to maximize value. Morality, I shall argue, only requires that we satisfice (promote sufficiently) value, and thus leaves us a greater range of options than maximizing act consequentialism recognizes.

Consequentialism broadly speaking is the idea that the moral rightness and wrongness of a thing (an act, a policy, an institution) is determined by the quality of its consequences. A prominent version is act consequentialism, which holds one morally always ought to do an act whose outcome is no worse than the outcome of any other act one might have done instead. This doctrine has little content—no commitment is involved as to how one should evaluate consequences—but is still highly controversial. What is called common-sense morality or CSM—moral views it is supposed many people embrace—rejects consequentialism as both too demanding and too permissive. Too permissive, because CSM includes constraints, rules one should not break even if doing so would produce the best attainable outcome. Too demanding, because CSM includes options. The demands of CSM mostly involve refraining from harming others in certain ways, and provided one observes these constraints, one is morally at liberty to do whatever one chooses, whether or not that produces the best outcome. In most situations, according to CSM, morality allow one many options, alternative acts one is morally permitted to do.

This is a general introduction to consequentialism.

“Perhaps the most common objection to consequentialism is this: it is impossible to know the future…This means that you will never be absolutely certain as to what all the consequences of your act will be…there may be long term bad effects from your act, side effects that were unforeseen and indeed unforeseeable…So how can we tell which act will lead to the best results overall – counting all the results? This seems to mean that consequentialism will be unusable as a moral guide to action. All the evidence available at the time of acting may have pointed to the conclusion that a given act was the right act to perform – and yet it may still turn out that what you did had horrible results, and so in fact was morally wrong. Indeed, if will never be possible to say for sure that any given act was right or wrong, since any event can continue to have further unseen effects down through history. Yet if it is impossible to tell whether any act is morally right or wrong, how can consequentialism possibly be a correct moral theory?”.

Critics have persistently charged that indirect consequentialism, despite the best efforts of its defenders, ultimately fails to appropriately account for friendship in the face of the alienation generated by the harsh demands of consequentialism. Robert F. Card has recently alleged that the dispositional emphasis of indirect consequentialism renders its defender incapable of rejecting problematic friendships that are seriously suboptimal. I argue that Card's criticism not only fails to undermine indirect consequentialism, but in fact provides considerations that both help us to better understand the theory and ultimately weigh in favor of it over Card's own brand of sophisticated consequentialism.

Over the last few decades, there has been an increasing interest in global consequentialism. Where act-consequentialism assesses acts in terms of their consequences, global consequentialism goes much further, assessing acts, rules, motives — and everything else — in terms of the relevant consequences. Compared to act-consequentialism it offers a number of advantages: it is more expressive, it is a simpler theory, and it captures some of the benefits of ruleconsequentialism without the corresponding drawbacks. In this paper, I explore the four different approaches to global consequentialism made by Parfit, Pettit and Smith, Kagan, and Feldman. I break these up into their constituent components, demonstrating the space of possible global consequentialist theories, and I present two new theories within this space.

The thesis of this paper is that consequentialism does not work as a comprehensive theory of right action. This paper does not offer a typical refutation, in that I do not claim that consequentialism is self-contradictory. One can with perfect consistency claim that the good is prior to the right and that the right consists in maximizing the good. What I claim, however, is that it is senseless to make such a claim. In particular, I attempt to show that the notion of what course of action maximizes the good has no content within a consequentialist framework. Since the problem that I identify rests with maximization, this refutation does not cut across the act/rule distinction. If rule consequentialism holds that there are occasions on which one should follow a rule rather than violate the rule in an optimific way, then it is not maximizing and my arguments do not apply; if not, then it collapses into act consequentialism. I have nothing to say about nonmaximizing forms of consequentialism.1 This refutation does, however, cut across the direct/indirect distinction.2 It makes no difference whether we take consequentialism as offering a principle of decision, or a standard of right. Presumably the former would be parasitic upon the latter for its legitimacy.

Its relentless pursuit of the good provides act-consequentialism with one sort of intuitive ethical rationale. But more indirect forms of consequentialism promise more intuitive normative implications, for instance the evil of even beneficent murders. I favor a middle way which combines the intuitive rationale of act-consequentialism and the intuitive normative implications of the best indirect forms. Multiple-Act Consequentialism or ‘MAC’ requires direct consequentialist evaluation of the options of group agents. It holds that one should only defect from a group act with good consequences if one can achieve better consequences by the defecting act alone than the entire group act achieves, and that when different beneficent group acts of which one is part specify roles which conflict, one should follow the role in the group act with better consequences. This paper develops MAC as a solution to the Trolley Problem. Section 1 concerns the relative advantages of direct and indirect consequentialisms. Section 2 develops MAC by a focus on competing conceptions of group agency. Section 3 applies MAC to the Trolley Problem.

Consequentialism is often charged with being self-defeating, for if a person attempts to apply it, she may quite predictably produce worse outcomes than if she applied some other moral theory. Many consequentialists have replied that this criticism rests on a false assumption, confusing consequentialism’s criterion of the rightness of an act with its position on decision procedures. Consequentialism, on this view, does not dictate that we should be always calculating which of the available acts leads to the most good, but instead advises us to decide what to do in whichever manner it is that will lead to the best outcome. Whilst it is typically afforded only a small note in any text on consequentialism, this reply has deep implications for the practical application of consequentialism, perhaps entailing that a consequentialist should eschew calculation altogether.
