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.

In this anthology, distinguished scholars--Thomas Nagel, T.M. Scanlon, John Rawls, Robert Nozick, Samuela Scheffler, Conrad D. Johnson, Bernard Williams, Peter Railton, Amartya Sen, Philippa Foot, and Derek Parfit-- debate arguments for and against the moral doctrine of consequentialism to present a complete view of this important topic in moral philosophy.

Both consequentialist and non-consequentialist ethical reasoning have difficulties in accounting for the value of consequences. Taken neat, consequentialism is too fierce in its emphasis on success and disregard of luck, while non-consequentialism seemingly over-values inner states and undervalues actual results. In Uneasy Virtue Julia Driver proposes a form of objective consequentialism which claims that characters are good if they typically (but not invariably) produce good results. This position addresses the problems moral luck raises for consequentialism, but requires some form of realism about traits of character. However, if our knowledge of mental states is ascriptive, this form of objective consequentialism may make excessive demands. Non-consequentialists may gain in so far as the theories of action to which they are typically committed are less demanding, and are built to take account of the typical or systematic connections between states of character and results of action.

Frank Jackson has put forward a famous thought experiment of a physician who has to decide on the correct treatment for her patient. Subjective consequentialism tells the physician to do what intuitively seems to be the right action, whereas objective consequentialism fails to guide the physician’s action. I suppose that objective consequentialists want to supplement their theory so that it guides the physician’s action towards what intuitively seems to be the right treatment. Since this treatment is wrong according to objective consequentialism, objective consequentialists have to license it without calling it right. I consider eight strategies to spell out the idea of licensing the intuitively right treatment and argue that objective consequentialism is on the horns of what I call the licensing dilemma : Either the physician’s action is not guided towards the intuitively right treatment. Or the guidance towards the intuitively right treatment is ad hoc in some respect or the other.

Theorists have consistently maintained that the most plausible forms of objective consequentialism must be probabilistic if and only if indeterminism is true.2 They claim: If indeterminism is true, then objective probabilities used to map such indeterminacies must be utilized by objective consequentialist moral theories; however, if determinism is true, probabilities play no role in objective consequentialist theorizing. I beg to differ. Assume determinism is true and I will show you that attractive forms of objective consequentialism must be probabilistic—and not for reasons related to our epistemic limitations either. In this way, I hope to shed some light upon the nature of objective consequentialism. Here’s my case. Consequentialist normative theories can be classified into two groups: subjective and objective. Subjective consequentialist theories might be characterized as those in which an agent’s beliefs concerning the possible consequences of an alternative (including perhaps: their likeliness to obtain should the alternative be performed, their intrinsic value, etc.) play a prominent role in determining that alternative’s normative..

Theorists have consistently maintained that the most plausible forms of objective consequentialism must be probabilistic if and only if indeterminism is true. This standard position, however popular, lacks sufficient motivation. Assume determinism to be true and an attempt will be made to show that attractive forms of objective consequentialism must be probabilistic - and not for reasons related to our epistemic limitations either.

Here it is argued that all extant objective formulations of consequentialism fail to deliver the normative implications that the spirit of objective consequentialism requires. My argument rests upon the claim that certain pairs of subjunctive conditionals with identical antecedents and incompatible consequents are such that neither of the pair is true.

Upon leveling the objection, the concept of an "objective" subjunctive probability is introduced and utilized in the transformation of a subjective version of expected act utility consequentialism into an objective version, one that is capable of dealing with the difficulties posed by the objection. I end by indicating some ways in which the closest thing to a plausible, objective form of consequentialism might be developed.

Frances Howard-Snyder has argued that objective consequentialism violates the principle that ‘ought’ implies ‘can’. In most situations, she claims, we cannot produce the best consequences available, although objective consequentialism says that we ought to do so. Here I try to show that Howard-Snyder's argument is unsound. The claim that we typically cannot produce the best consequences available is doubtful. And even if there is a sense of ‘producing the best consequences’ in which we cannot do so, objective consequentialism does not entail that we ought, in this sense, to produce the best consequences.

This is a general introduction to consequentialism.

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.

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.
