Maximalism is the view that an agent is permitted to perform a certain type of action if and only if she is permitted to perform some instance of this type, where φ-ing is an instance of ψ-ing if and only if φ-ing entails ψ-ing but not vice versa. Now, the aim of this paper is not to defend maximalism, but to defend a certain account of our options that when combined with maximalism results in a theory that accommodates the idea (...) that a moral theory ought to be morally harmonious—that is, ought to be such that the agents who satisfy the theory, whoever and however numerous they may be, are guaranteed to produce the morally best world that they have the option of producing. I argue that, for something to count as an option for an agent, it must, in the relevant sense, be under her control. And I argue that the relevant sort of control is the sort that we exercise over our reasons-responsive attitudes by being both receptive and reactive to reasons. I call this sort of control rational control, and I call the view that φ-ing is an option for a subject if and only if she has rational control over whether she φs rationalism. When we combine this view with maximalism, we get rationalist maximalism, which I argue is a promising moral theory. (shrink)

Many prominent ethicists, including Shelly Kagan, John Rawls, and Thomas Scanlon, accept a kind of epistemic modesty thesis concerning our capacity to carry out the project of ethical theorizing. But it is a thesis that has received surprisingly little explicit and focused attention, despite its widespread acceptance. After explaining why the thesis is true, I argue that it has several implications in metaethics, including, especially, implications that should lead us to rethink our understanding of Reductive Realism. In particular, the thesis (...) of epistemic modesty in ethics implies a kind of epistemic modesty about the metaphysical nature of ethics, if Reductive Realism about the metaphysical nature of ethics is true, and it implies that normative concepts are indispensable to practical deliberation in a way that answers an influential objection to Reductive Realism from Jonathan Dancy, David Enoch, William FitzPatrick, and Derek Parfit.

This article proposes ‘Recursive Consequentialism’: the moral theory which gives agents whatever advice will produce good consequences by being given. It can be thought of as a version of Donald Regan's ‘Cooperative Utilitarianism’ to which two additional elements have been added: allowing people with differing conceptions of ‘good consequences’, e.g., a Utilitarian and a non-Utilitarian, to cooperate with one another, and taking into account the full consequences of accepting, not just complying with, moral guidance. The theory is motivated by a (...) series of game-theoretic examples in which adherence to alternative Consequentialist moral theories produces bad consequences. (shrink)

Group-based reasons are reasons to play one’s part in some pattern of action that the members of some group could perform, because of the good features of the pattern. This paper discusses three broad conceptions of such reasons. According to the agency-first conception, there are no group-based reasons in cases where the relevant group is not or would not be itself an agent. According to the behaviour-first conception, what matters is that the other members of the group would play their (...) parts in the relevant pattern, not whether they would have the cooperative intentional states constitutive of group agency in doing so. This paper argues against these conceptions and in favour of the powers-first conception, according to which what matters is that the members of the group have practically relevant powers. (shrink)

I show that Kavka's toxin puzzle raises a problem for the “Responsibility Theodicy,” which holds that the reason God typically does not intervene to stop the evil effects of our actions is that such intervention would undermine the possibility of our being significantly responsible for overcoming and averting evil. This prominent theodicy seems to require that God be able to do what the agent in Kavka's toxin story cannot do: stick by a plan to do some action at a future (...) time even though when that time comes, there will be no good reason for performing that action. I assess various approaches to solving this problem. Along the way, I develop an iterated variant of Kavka's toxin case and argue that the case is not adequately handled by standard causal decision theory. (shrink)

This paper outlines a new metasemantic theory of moral reason statements, focused on explaining how the reasons thus stated can be inescapable. The motivation for the theory is in part that it can explain this and other phenomena concerning moral reasons. The account also suggests a general recipe for explanations of conceptual features of moral reason statements. (Published with Open Access.).

How should we act when uncertain about the moral truth, or when trying to remain neutral between competing moral theories? This dissertation argues that some types of actions and policies are relatively likely to be approved by a very wide range of moral theories—even theories which have never yet been formulated, or which appear to cancel out one another's advice. For example, I argue that actions and policies which increase a moral agent's access to primary goods also tend to increase (...) that agent's likelihood of bringing about good consequences, even under varying and mutually incompatible hypotheses about what consequences count as "good". We therefore have a subjective, pro tanto moral reason to perform such actions and enact such policies—one whose justification does not require treating any particular theory as especially probable, but instead merely requires treating at least one at-least-partly consequentialist moral theory as an open hypothesis, and is therefore applicable even under conditions of moral uncertainty or moral neutrality. My discussion begins abstractly, but as it progresses it gradually applies its framework to increasingly concrete issues. I find that the justification of some liberal policies—in the classical sense of "liberal"—can be accomplished with significantly fewer moral assumptions than have traditionally been relied upon.

A dynamic semantics for iffy oughts offers an attractive alternative to the folklore that Chisholm's paradox enforces an unhappy choice between the intuitive inference rules of factual and deontic detachment. The first part of the story told here shows how a dynamic theory about ifs and oughts gives rise to a nonmonotonic perspective on deontic discourse and reasoning that elegantly removes the air of paradox from Chisholm's puzzle without sacrificing any of the two detachment principles. The second part of the (...) story showcases two bonus applications of the framework suggested here: it offers a response to Forrester's gentle murder paradox and avoids Kolodny and MacFarlane's miners paradox about deontic reasoning under epistemic uncertainty. A comparison between the dynamic semantic proposal made in this paper and a more conservative approach combining a static semantics with a dynamic pragmatics is provided. (shrink)

This paper lists a number of puzzles for shared obligations – puzzles about the role of individual influence, individual reasons to contribute towards fulfilling the obligation, about what makes someone a member of a group sharing an obligation, and the relation between agency and obligation – and proposes to solve them based on a general analysis of obligations. On the resulting view, shared obligations do not presuppose joint agency.

This article proposes a way of understanding Kantianism, act-utilitarianism and some other important ethical theories according to which they are all versions of the same kind of theory, sharing a common structure. I argue that this is a profitable way to understand the theories discussed. It is charitable to the theories concerned; it emphasizes the common ground between them; it gives us insights into the differences between them; and it provides a method for generating new ethical theories worth studying. The (...) article briefly discusses the relationship between these ideas and some other recent proposals that emphasize the common ground between Kantianism and versions of consequentialism.

Objectivists and perspectivists disagree about the question of whether what an agent ought to do depends on the totality of facts or on the agent’s limited epistemic perspective. While objectivism fails to account for normative guidance, perspectivism faces the challenge of explaining phenomena (occurring most notably in advice, but also in first-personal deliberation) in which the use of “ought” is geared to evidence that is better than the evidence currently available to the agent. This paper aims to defend perspectivism by (...) developing a perspectivist account that captures the phenomena in question. (shrink)

This paper works within a particular framework for reasoning about actions—sometimes known as the framework of “stit semantics”—originally due to Belnap and Perloff, based ultimately on the theory of indeterminism set out in Prior’s indeterministic tense logic, and developed in full detail by Belnap, Perloff, and Xu [3]. The issues I want to consider arise when certain normative, or decision theoretic, notions are introduced into this framework: here I will focus on the notion of a right action, and so on (...) the formulation of act utilitarianism within this indeterministic setting. The problem is simply that there are two different, and conflicting, ways of defining this notion, both well-motivated, and both carrying intuitive weight. (shrink)

Coordination problems, problems in which each agent's expected utility depends upon what other agents do, pose a problem for act utilitarianism. When the agents are act utilitarians and know of each other that they are so, they seem unable to achieve optimal outcomes in certain coordination problems. I examine various ways the act utilitarian might attempt to solve this problem, where act utilitarianism is interpreted within the framework of subjective expected utility theory. In particular, a new method for computing expected (...) utility,dynamic deliberation, deserves examination as a possible act utilitarian solution to coordination problems. I argue that even dynamic deliberation fails to give the act utilitarian what he needs in coordination problems, and that the failure of act utilitarianism for such problems suggests the need for an alternative theory of moral choice along rule utilitarian lines.

This paper examines the idea of an extended unit of action, which is the idea that the reasons for or against an individual action can depend on the qualities of a larger pattern of action of which it is a part. One concept of joint action is that the unit of action can be extended in this sense. But the idea of an extended unit of action is surprisingly minimal in its commitments. The paper argues for this conclusion by examining (...) uses of the idea of an extended unit of action in four theoretical contexts. It also explains why the idea of an extended unit of action need not involve magical thinking, and discusses possible replies to an objection based on a worry about recklessness. (shrink)

Individualists claim that collective obligations are reducible to the individual obligations of the collective’s members. Collectivists deny this. We set out to discover who is right by way of a deontic logic of collective action that models collective actions, abilities, obligations, and their interrelations. On the basis of our formal analysis, we argue that when assessing the obligations of an individual agent, we need to distinguish individual obligations from member obligations. If a collective has a collective obligation to bring about (...) a particular state of affairs, then it might be that no individual in the collective has an individual obligation to bring about that state of affairs. What follows from a collective obligation is that each member of the collective has a member obligation to help ensure that the collective fulfills its collective obligation. In conclusion, we argue that our formal analysis supports collectivism. (shrink)

This paper argues in favor of a particular account of decision‐making under normative uncertainty: that, when it is possible to do so, one should maximize expected choice‐worthiness. Though this position has been often suggested in the literature and is often taken to be the ‘default’ view, it has so far received little in the way of positive argument in its favor. After dealing with some preliminaries and giving the basic motivation for taking normative uncertainty into account in our decision‐making, we (...) consider and provide new arguments against two rival accounts that have been offered—the accounts that we call ‘My Favorite Theory’ and ‘My Favorite Option’. We then give a novel argument for comparativism—the view that, under normative uncertainty, one should take into account both probabilities of different theories and magnitudes of choice‐worthiness. Finally, we further argue in favor of maximizing expected choice‐worthiness and consider and respond to five objections. (shrink)

There is a renewed debate about modus ponens. Strikingly, the recent counterexamples in Cantwell, Dreier and MacFarlane and Kolodny are generated by restricted readings of the ‘if’-clause. Moreover, it can be argued on general grounds that the restrictor view of conditionals developed in Kratzer and Lewis leads to counterexamples to modus ponens. This paper provides a careful analysis of modus ponens within the framework of the restrictor view. Despite appearances to the contrary, there is a robust sense in which modus (...) ponens is valid, owing to the fact that conditionals do not only allow for restricted readings but have bare interpretations, too.

It has become increasingly common for philosophers to distinguish between objective and subjective rightness, and there has been much discussion recently about what an adequate theory of subjective rightness looks like. In this article, I propose a new theory of subjective rightness. According to it, an action is subjectively right if and only if it minimizes expected objective wrongness. I explain this theory in detail and argue that it avoids many of the problems that other theories of subjective rightness face. (...) I end by responding to some objections. (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)

In discussions of moral responsibility for collectively produced effects, it is not uncommon to assume that we have to abandon the view that causal involvement is a necessary condition for individual co-responsibility. In general, considerations of cases where there is “a mismatch between the wrong a group commits and the apparent causal contributions for which we can hold individuals responsible” motivate this move. According to Brian Lawson, “solving this problem requires an approach that deemphasizes the importance of causal contributions”. Christopher (...) Kutz’s theory of complicitious accountability in Complicity from 2000 is probably the most well-known approach of that kind. Standard examples are supposed to illustrate mismatches of three different kinds: an agent may be morally co-responsible for an event to a high degree even if her causal contribution to that event is a) very small, b) imperceptible, or c) non-existent (in overdetermination cases). From such examples, Kutz and others conclude that principles of complicitious accountability cannot include a condition of causal involvement. In the present paper, I defend the causal involvement condition for co-responsibility. These are my lines of argument: First, overdetermination cases can be accommodated within a theory of coresponsibility without giving up the causality condition. Kutz and others oversimplify the relation between counterfactual dependence and causation, and they overlook the possibility that causal relations other than marginal contribution could be morally relevant. Second, harmful effects are sometimes overdetermined by non-collective sets of acts. Over-farming, or the greenhouse effect, might be cases of that kind. In such cases, there need not be any formal organization, any unifying intentions, or any other noncausal criterion of membership available. If we give up the causal condition for coresponsibility it will be impossible to delimit the morally relevant set of acts related to those harms. Since we sometimes find it fair to blame people for such harms, we must question the argument from overdetermination. Third, although problems about imperceptible effects or aggregation of very small effects are morally important, e.g. when we consider degrees of blameworthiness or epistemic limitations in reasoning about how to assign responsibility for specific harms, they are irrelevant to the issue of whether causal involvement is necessary for complicity. Fourth, the costs of rejecting the causality condition for complicity are high. Causation is an explicit and essential element in most doctrines of legal liability and it is central in common sense views of moral responsibility. Giving up this condition could have radical and unwanted consequences for legal security and predictability. However, it is not only for pragmatic reasons and because it is a default position that we should require stronger arguments (than conflicting intuitions about “mismatches”) before giving up the causality condition. An essential element in holding someone to account for an event is the assumption that her actions and intentions are part of the explanation of why that event occurred. If we give up that element, it is difficult to see which important function responsibility assignments could have. (shrink)

The concepts of 'ethical' and 'socially responsible' investment (SRI) have become increasingly popular in recent years and funds which offer this kind of investment have attracted many individual inve... merstors. The present book addresses the issue of 'How ought one to invest?' by critically engaging with the ideas of the proponents of this movement about what makes 'ethical' investing ethical. The standard suggestion that ethical investing simply consists in refraining from investing in certain 'morally unacceptable companies' is criticised for being (...) both too rigid (often resting on absolute moral rules which lead to an austere conclusion) and too ineffective for individual investors (investors who after all control only a small part of the investment universe). Furthermore, the idea that ethical investing could consist in engaging more actively with the companies one invests in, in order to make them change their ways and become more socially responsible, is criticised for being just as ineffective for individual investors. Some more radical alternatives are elaborated on and defended - for instance, the suggestion that investors should make as much money from their investments as possible and then donate the proceeds to socially worthwhile charities. From similar suggestions, the common idea that there is no conflict between morality and profitability, or that genuinely ethical investing can be just as profitable as mainstream investing, is criticised for being too naïve. Making a difference may indeed require personal sacrifice of investors, but it is argued that the needs of the possible recipients of philanthropy are morally more important than the luxury of investment returns.

How do rational agents coordinate in a single-stage, noncooperative game? Common knowledge of the payoff matrix and of each player's utility maximization among his strategies does not suffice. This paper argues that utility maximization among intentions and then acts generates coordination yielding a payoff-dominant Nash equilibrium. ‡I thank the audience at my paper's presentation at the 2006 PSA meeting for many insightful points. †To contact the author, please write to: Philosophy Department, University of Missouri, Columbia, MO 65211; e-mail: [email protected].

Roughly speaking, maximalism is the view that only certain options are to be assessed in terms of whether they have some right‐making property (such as that of producing optimal consequences), whereas omnism is the view that all options are to be assessed in terms of whether they have this property. I argue that maximalism is preferable to omnism because it provides a more plausible solution to what's known as the problem of act versions and is not subject to any significant (...) problems of its own. If I'm right, then most moral theories, which are versions of omnism, need revision. (shrink)

The view that what one ought, or is obligated, to do is the best that one can do faces a problem even from the perspective of someone sympathetic with the view: there are cases of group action where, through lack of cooperation, the best that can be done is not done and yet where, it seems, each individual does the best that he or she can do. In this paper, various attempts to deal with this problem are criticized and then (...) a new solution is offered, one which requires "connected" individuals to be "transigent" relative to one another concerning possible group outcomes.

Among various cases that equally admit of evidentialist reasoning, the supposedly evidentialist solution has varying degrees of intuitive attractiveness. I suggest that cooperative reasoning may account for the appeal of apparently evidentialist behavior in the cases in which it is intuitively attractive, while the inapplicability of cooperative reasoning may account for the unattractiveness of evidentialist behaviour in other cases. A collective causal power with respect to agreed outcomes, not evidentialist reasoning, makes cooperation attractive in the Prisoners' Dilemma. And a natural (...) though unwarranted assumption of such a power may account for the intuitive appeal of the one-box response in Newcomb's Problem. (shrink)

This dissertation is a discussion of the challenge that cases of over-determination pose to Act-Consequentialism. Although there are many realistic examples of such cases – for example, pollution, overfishing, or the election of an inappropriate politician – I consider structurally purer examples, one of which I call “Case One.” Suppose that you and I independently shoot and kill a third person called “Victim.” Our bullets arrive at the same time and each shot would have killed Victim by itself. Finally, Victim (...) would not have been killed, if neither of us had pulled the trigger. According to the Standard Version of Act-Consequentialism, an action is wrong if and only if it has an alternative whose consequences would be intrinsically better. Case One challenges the Standard Version because there does not seem to be such an alternative to my action: Victim would have died by your shot if I had not shot him, and similar remarks apply to your action. The dissertation is structured as follows. After Chapter One, which briefly introduces the main issues of the dissertation, I turn to Chapter Two – “Preliminaries” – where I outline the Standard Version and highlight the main characteristics of over-determination cases. These cases are divided into cases of redundant difference making and cases of redundant causation. Cases of redundant causation are subdivided further into cases of causal over-determination and pre-emption. I make an important stipulation in this chapter. I say that our actions in Case One and similar cases are “redundant negative difference makers.” In Chapter Three – “Replies” – I consider whether the proponent of Act-Consequentialism might question the intuition that you and I, respectively, act wrongly in Case One. The proponent might accept that we have this intuition but explain it away, or she might deny that we have the intuition and instead point to something else that is wrong in this kind of case. For example, she could suggest that although neither you nor I act wrongly individually, we act wrongly together. I argue that these replies are problematic. For instance, explaining away this intuition might also force us to explain away intuitions that support the Standard Version. In Chapter Four – “Causal Consequences” – I discuss an alternative version of Act-Consequentialism that might seem to fare better. The Standard Version interprets the term “outcome of an action” as referring to the entire possible world that would obtain, if the action were performed. The version I have in mind, the “Causal Consequences Version of Act-Consequentialism,” understands “outcome of an action” as instead referring to the causal consequences of the action. It seems clear that you and I, respectively, cause the state of affairs that Victim dies in Case One. However, I show that the Causal Consequences Version has a number of unattractive implications. In Chapter Five – “the Non-Standard Version” – I suggest another alternative version of Act-Consequentialism. This version – the Non-Standard Version – implies that you and I act wrongly in Case One. Roughly, the Non-Standard Version says that an action is wrong if and only if it has an alternative whose consequences would be intrinsically better, or is a redundant negative difference maker. The Non-Standard Version is similar to a principle suggested by Derek Parfit. However, I shall argue that the Non-Standard Version is preferable to Parfit’s principle. In Chapter Six – “Further Cases” – I discuss a number of cases that challenge the Non-Standard Version. For example, what would the Non-Standard Version imply in a case very similar to Case One but where I would have killed another person, if I had not shot Victim? I argue that the Non-Standard Version handles this and other problematic cases, and that it is therefore a plausible alternative to the Standard Version. (shrink)

This paper comprises three sections. First, we offer a traditional defence of deontology, in the manner of, for example, W.D. Ross (1965). The leading idea of such a defence is that the right is independent of the good. Second, we modify the now standard account of the distinction, in terms of the agent-relative/agentneutral divide, between deontology and consequentialism. (This modification is necessary if indirect consequentialism is to count as a form of consequentialism.) Third, we challenge a value-based defence of deontology (...) proposed by Quinn (1993), Kamm (1989, 1992), and Nagel (1995). (shrink)

There is a theory that one ought morally to do the best one can, when ‘best’ is suitably interpreted. There are also some examples in which, although every agent involved does the best she can, the group composed of them does not. Some philosophers think that these examples show the theory to be wrong. In particular, they think that such examples motivate a view which incorporates a requirement of cooperativeness in a particular way, though they disagree as to the exact (...) nature of this requirement. This paper will argue both that such views are problematic and that the examples do not motivate departure from the original theory. (shrink)
