Is consequentialism consistent with common-sense morality? I argue for a negative answer to this question. In Sections 1-4, I develop and defend a definition for “consequentialism.” In Section 5, I attempt to show that, given this definition, consequentialism and common-sense morality cannot be reconciled. In Section 6, I argue that, on the definition of consequentialism I defend, consequentialism should be understood, not as a view about the relationship between the deontic and the evaluative (as many philosophers suppose), but as a view about the relationship between the deontic and time.

Frances Howard-Snyder argues that objective consequentialism should be rejected because it violates the principle of ‘ought’ implies ‘can’ in asking us to do what we cannot. In this comment I suggest that Howard-Snyder does not take sufficiently seriously the chief defence of objective consequentialism, which reformulates it so that it applies only to actions we can perform. Nonetheless, I argue that there are arguments relating to ‘ought’ implies ‘can’ which discredit objective consequentialism even if it is thus reformulated. These arguments also cause problems for a reformulated version of subjective consequentialism.

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.

Derek Parfit, Philip Pettit and Michael Smith defend a version of consequentialism that covers everything. I argue that this version of consequentialism is false. Consequentialism, I argue, can only cover things that belong to a combination of things that agents can bring about.

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.

Objective consequentialism is often criticized because it is impossible to know which of our actions will have the best consequences. Why exactly does this undermine objective consequentialism? I offer a new link between the claim that our knowledge of the future is limited and the rejection of objective consequentialism: that ‘ought’ implies ‘can’ and we cannot produce the best consequences available to us. I support this apparently paradoxical contention by way of an analogy. I cannot beat Karpov at chess in spite of the fact that I can make each of many series of moves, at least one of which would beat him. I then respond to a series of objections. In the process I develop an account of the ‘can’ of ability. I conclude with some remarks about the bearing this attack has on subjective consequentialism.

Recent work on consequentialism has revealed it to be more flexible than previously thought. Consequentialists have shown how their theory can accommodate certain features with which it has long been considered incompatible, such as agent-centered constraints. This flexibility is usually thought to work in consequentialism’s favor. I want to cast doubt on this assumption. I begin by putting forward the strongest statement of consequentialism’s flexibility: the claim that, whatever set of intuitions the best nonconsequentialist theory accommodates, we can construct a consequentialist theory that can do the same while still retaining whatever is compelling about consequentialism. I argue that if this is true then most likely the non-consequentialist theory with which we started will turn out to have that same compelling feature. So while this extreme flexibility, if indeed consequentialism has it (a question I leave to the side), makes consequentialism more appealing, it makes non-consequentialism more appealing too.

The paper proposes a new version of direct act consequentialism that will provide the same evaluations of the rightness of acts as indirect disposition, motive or character consequentialism, thus reconciling the coherence of direct consequentialism with the plausible results in cases of indirect consequentialism. This is achieved by seeing that adopting certain kinds of moral dispositions causally constrains our future acts, so that the maximizing acts ruled out by the disposition can no longer be chosen. Thus when we act we do the best we can, which is all that is required for rightness according to act consequentialism.

Tim Mulgan presents a penetrating examination of consequentialism: the theory that human behavior must be judged in terms of the goodness or badness of its consequences. The problem with consequentialism is that it seems unreasonably demanding, leaving us no room for our own aims and interests. In response, Mulgan offers his own, more practical version of consequentialism--one that will surely appeal to philosophers and laypersons alike.

This is a general introduction to consequentialism.
