Objective and Subjective Consequentialism

A theory of what we should believe should include a theory of what we should believe when we are uncertain about what we should believe and/or uncertain about the factors that determine what we should believe. In this paper, I present a novel theory of what we should believe that gives normative externalists a way of responding to a suite of objections having to do with various kinds of error, ignorance, and uncertainty. This theory is inspired by recent work in (...) ethical theory in which non-consequentialists 'consequentialize' their theories and then use the tools of decision-theory to give us an account of what we ought (in some sense) to do when we're uncertain about what we ought (in some primary sense) to do. On my proposal, because what we ought to do is acquire knowledge and avoid ignorance, we ought to believe iff the probability of coming to know is sufficiently high. This view has a number of important virtues. Among them, it gives us a unified story about how defeaters defeat (a theory developed with Julien Dutant), explains puzzling intuitions about the differences between lottery cases, preface cases, and cases of perceptual knowledge, and provides externalists (and internalists!) with a general framework for thinking about subjective normativity. It's also relatively brief. (shrink)

A compelling requirement on normative theories is that they should be satisfiable, that is, in every possible choice situation with a finite number of alternatives, there should be at least one performable act such that, if one were to perform that act, one would comply with the theory. In this paper, I argue that, given some standard assumptions about free will and counterfactuals, Objective Act Consequentialism violates this requirement.

Consequentialism is a focal point of discussion and a driving force behind important developments in moral philosophy. Recently, the debate has shifted in focus and in style. By seeking to consequentialize rival moral theories, in particular those with agent-relative characteristics, and by framing accounts in terms of reasons rather than in terms of value, an emerging new wave consequentialism has presented - at much higher levels of abstraction - theories which proved extremely flexible and powerful in meeting long-standing and influential (...) objections. This volume of new essays on new wave consequentialism initiates and stimulates novel lines of discussions among proponents and their critics. The contributions explore new directions in new wave consequentialism and present refined conceptual frameworks (in Part I), raise challenging fundamental problems for these frameworks and the new wave's theoretical basis (in Part II), and give a balanced assessment of the new wave's limits and achievements in specific contexts of commonsense moral practice (in Part III).

This paper argues that objective consequentialism is incompatible with the rationales of ‘ “ought” implies “can” ’ – with the considerations, that is, that explain or justify this principle. Objective consequentialism is the moral doctrine that an act is right if and only if there is no alternative with a better outcome, and wrong otherwise. An act is obligatory if and only if it is wrong not to perform it. According to ‘ “ought” implies “can” ’, a person is morally (...) obligated to φ only if the person can φ. The rationales of ‘ “ought” implies “can” ’ include considerations related to intuitive plausibility, action-guidance, blameworthiness and fairness, and the nature of practical reasons. (shrink)

Some philosophers hold that objective consequentialism is false because it is incompatible with the principle that “ought” implies “can”. Roughly speaking, objective consequentialism is the doctrine that you always ought to do what will in fact have the best consequences. According to the principle that “ought” implies “can”, you have a moral obligation to do something only if you can do that thing. Frances Howard-Snyder has used an innovative thought experiment to argue that sometimes you cannot do what will in (...) fact have the best consequences because you do not know what will in fact have the best consequences. Erik Carlson has raised two objections against Howard-Snyder’s argument. This paper examines Howard-Snyder’s argument as well as Carlson’s objections, arguing that Carlson’s objections do not go through but Howard-Snyder’s argument fails nonetheless. Moreover, this paper attempts to show that objective consequentialism and other objectivist moral theories are compatible with the principle that “ought” implies “can”. Finally, this paper analyses a special kind of inability: ignorance-induced inability. (shrink)

In his new book, The Dimensions of Consequentialism, Martin Peterson proposes a version of multi-dimensional consequentialism according to which risk is one among several dimensions. We argue that Peterson’s treatment of risk is unsatisfactory. More precisely, we want to show that all problems of one-dimensional (objective or subjective) consequentialism are also problems for Peterson’s proposal, although it may fall prey to them less often. In ending our paper, we address the objection that our discussion overlooks the fact that Peterson’s proposal (...) is not the best version of multi-dimensional consequentialism. Our reply is that the possibilities of improving multi-dimensional consequentialism are very limited as far as risk is concerned. (shrink)

Moral wrongness comes in degrees. On a consequentialist view of ethics, the wrongness of an act should depend, I argue, in part on how much worse the act's consequences are compared with those of its alternatives and in part on how difficult it is to perform the alternatives with better consequences. I extend act consequentialism to take this into account, and I defend three conditions on consequentialist theories. The first is consequentialist dominance, which says that, if an act has better (...) consequences than some alternative act, then it is not more wrong than the alternative act. The second is consequentialist supervenience, which says that, if two acts have equally good consequences in a situation, then they have the same deontic status in the situation. And the third is consequentialist continuity, which says that, for every act and for any difference in wrongness δ greater than zero, there is an arbitrarily small improvement of the consequences of the act which would, other things being equal, not change the wrongness of that act or any alternative by more than δ. I defend a proposal that satisfies these conditions. (shrink)

Some moral theories, such as objective forms of consequentialism, seem to fail to be practically useful: they are of little to no help in trying to decide what to do. Even if we do not think this constitutes a fatal flaw in such theories, we may nonetheless agree that being practically useful does make a moral theory a better theory, or so some have suggested. In this paper, I assess whether the uncontroversial respect in which a moral theory can be (...) claimed to be better if it is practically useful can provide a ground worth taking into account for believing one theory rather than another. I argue that this is not the case. The upshot is that if there is a sound objection to theories such as objective consequentialism that is based on considerations of practical usefulness, the objection requires that it is established that the truth about what we morally ought to do cannot be epistemically inaccessible to us. The value of practical usefulness has no bearing on the issue. (shrink)

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. (shrink)

In this paper I present a new argument for prospectivism: the view that, for a consequentialist, rightness depends on what is prospectively best rather than what would actually be best. Prospective bestness depends on the agent’s epistemic position, though exactly how that works is not straightforward. I clarify various possible versions of prospectivism, which differ in how far they go in relativizing to the agent’s limitations. My argument for prospectivism is an argument for moderately objective prospectivism, according to which the (...) right thing to do is what would make sense given reasonable beliefs, reasonable probability estimates and a reasonable understanding of value. My argument is an argument for this form of prospectivism over objectivism. Arguments about prospectivism and objectivism usually use an example with the following form: an agent has a choice between options, one she knows would be acceptable, while the other could either be catastrophic or very good. Objectivists argue that the right thing to do is what would in fact be best (though the agent cannot know which option that is) while prospectivists argue that the agent’s ignorance is relevant, and the right thing to do is to compromise. The question is how we should understand the underlying argument. It is not about action guidance. Moderately objective prospectivism is not action guiding, because an actual agent may not have access to reasonable beliefs, probability estimates and so on. Another common argument is that the objective notion is the primary one. I show that there are no good grounds for this claim. My argument uses the distinction between rightness and goodness to show that a consequentialist theory, that bases rightness on goodness, should take into account how much goodness is at stake. Crucially, potential losses as well as gains are relevant. So long as goodness, rather than rightness, is in the driving seat, we should not be ‘bestness fetishists’. As the name suggest, this would be an irrational privileging of the best option. This argument does not apply to pure deontology: a pure deontology does not use the notion of goodness at all, and so there is nothing to compromise with. If the agent does not know what is right, there is nothing further to say. I end by arguing against a recent strategy that aims to show that although objectivism is true (the right option is the best one), we should sometimes do what is wrong (i.e. what is prospectively best). I argue that in so far as this is correct it is simply prospectivism with awkward terminology. (shrink)

There are two distinct views on how to formulate an objective consequentialist account of the deontic status of actions, actualism and possibilism. On an actualist account, what matters to the deontic status of actions is only the value of the outcome an action would have, if performed. By contrast, a possibilist account also takes into account the value of the outcomes that an action could have. These two views come apart in their deontic verdicts when an agent is imperfect in (...) an avoidable way, viz., when agent brings about less good than she could. In this paper, I offer an argument against actualism that draws on the connection between moral obligation and practical reasons. (shrink)

This discussion note attempts to show that, pace Niko Kolodny and John MacFarlane, the Miners case intuitively speaks in favor of subjectivism. I argue that properly understood the intuitively correct judgements concerning the case are compatible with subjectivism. My argument is based, among other things, on a comparison between the Minders case and other cases as well as on considerations of blameworthiness.

Act-utilitarianism and other theories in normative ethics confront the implementability problem: normal human agents, with normal human epistemic abilities, lack the information needed to use those theories directly for the selection of actions. Two Level Theories have been offered in reply. The theoretical level component states alleged necessary and sufficient conditions for moral rightness. That component is supposed to be true, but is not intended for practical use. It gives an account of objective obligation. The practical level component is offered (...) as an implementable system for the choice of actions by agents lacking some relevant information. It gives an account of subjective obligation. Several different ways of developing Two Levelism are explained and criticized. Five conditions that must be satisfied if the practical level principle is to be a good match for a given theoretical level principle are stated. A better form of Two Levelism is presented. (shrink)

Consequentialism is the view that the rightness or wrongness of actions depend solely on their consequences. It is one of the most influential, and controversial, of all ethical theories. In this book, Julia Driver introduces and critically assesses consequentialism in all its forms. After a brief historical introduction to the problem, Driver examines utilitarianism, and the arguments of its most famous exponents, John Stuart Mill and Jeremy Bentham, and explains the fundamental questions underlying utilitarian theory: what value is to be (...) specified and how it is to be maximized. Driver also discusses indirect forms of consequentialism, the important theories of motive consequentialism and virtue consequentialism, and explains why the distinction between subjective and objective consequentialism is so important. Including helpful features such as a glossary, chapter summaries, and annotated further reading at the end of each chapter, Consequentialism is ideal for students seeking an authoritative and clearly explained survey of this important problem.

A general introduction to consequentialism.

Define teleology as the view that requirements hold in virtue of facts about value or goodness. Teleological views are quite popular, and in fact some philosophers (e.g. Dreier, Smith) argue that all (plausible) moral theories can be understood teleologically. I argue, however, that certain well-known cases show that the teleologist must at minimum assume that there are certain facts that an agent ought to know, and that this means that requirements can't, in general, hold in virtue of facts about value (...) or goodness. I then show that even if we grant those 'ought's teleology still runs into problems. A positive justification of teleology looks like it will require an argument of this form: O(X); if X, then O(Y); therefore O(Y). But this form of argument isn't in general valid. I conclude by offering two positive suggestions for those attracted to a teleological outlook. (shrink)

Two meanings of "subjective consequentialism" are distinguished: conscious deliberation with the aim of producing maximally-good consequences, versus acting in ways that, given one's evidence set and reasoning capabilities, is subjectively most likely to maximize expected consequences. The latter is opposed to "objective consequentialism," which demands that we act in ways that actually produce the best total consequences. Peter Railton's arguments for a version of objective consequentialism confuse the two subjective forms, and are only effective against the first. After reviewing the (...) arguments of Eric Wiland and Frances Howard-Snyder against objective consequentialism, two of Railton's arguments which might seem to count against the second form of subjective consequentialism are shown to be ineffective. This leaves subjective consequentialism as a viable theory to replace objective consequentialism with. (shrink)

A decision value alternative is proposed to the various formulations of the principle of utility, which counsel maimization of expected utility as utility is variously conceived. Decision value factors expected utility into causal expected utility and evidential expected utility, and it adds a third factor --- symbolic utility. This latter introduces deontological and a ‘perceived value’ elements into calculations of utility. It also suggests a solution to a lingering problem in population ethics, the so-called Repugnant Conclusion that consequentialist thinking demands (...) a vast population of people leading lives barely worth living. (shrink)

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. (shrink)

Utilitarians are attracted to the idea that an act is morally right iff it leads to the best outcome. But critics have pointed out that in many cases we cannot determine which of our alternatives in fact would lead to the best outcome. So we can’t use the classic principle to determine what we should do. It’s not “practical”; it’s not “action-guiding”. Some take this to be a serious objection to utilitarianism, since they think a moral theory ought to be (...) practical and action-guiding. In response, some utilitarians propose to modify utilitarianism by replacing talk of actual utility with talk of expected utility. Others propose to leave the original utilitarian principle in place, but to combine it with a decision procedure involving expected utility. What all these philosophers have in common is this: they move toward expected utility in order to defend utilitarianism against the impracticality objection. My aim in this paper is to cast doubt on this way of replying to the objection. My central claim is that if utilitarians are worried about the impracticality objection, they should not turn to expected utility utilitarianism. That theory does not provide the basis for a cogent reply to the objection. (shrink)

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 UneasyVirtue 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.

It seems that the debate between objective and subjective consequentialists might be resolved by appealing to the ought implies can principle. Howard-Snyder has suggested that if one does not know how to do something, cannot do it, and thus one cannot have an obligation to do it. I argue that this depends on an overly rich conception of ability, and that we need to look beyond the ought implies can principle to answer the question. Once we do so, it appears (...) that Prichard might have been at least partly right when he claimed that obligations are tryings. I go some way to defending a diluted version of Prichard's view. (shrink)

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. (shrink)

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. (shrink)

On the agent-relativity thesis, what an agent ought to do is a function of the evidence available to her about the consequences of her potential actions. On the objectivity thesis, what an agent ought to do is a function of what the consequences of her potential actions would be, regardless of the evidence available to her. This article argues for the agent-relativity thesis. The main opposing argument, due to Thomson, points to cases where a bystander can see that an agent (...) is about to do something which, unknown to the agent, would have terrible consequences, and says to the agent: "You ought not to do that!" The bystander's utterance seems true, but it is argued that this is consistent with the agent-relativity thesis, which also enjoys support from other directions. (shrink)

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. (shrink)

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 play a prominent role in determining that alternative’s normative.
