According to a naïve view sometimes apparent in the writings of moral philosophers, ‘ought’ often expresses a relation between agents and actions – the relation that obtains between an agent and an action when that action is what that agent ought to do. It is not part of this naïve view that ‘ought’ always expresses this relation – on the contrary, adherents of the naïve view are happy to allow that ‘ought’ also has an epistemic sense, (...) on which it means, roughly, that some proposition is likely to be the case, and adherents of the naïve view are also typically happy to allow that ‘ought’ also has an evaluative sense, on which it means, roughly, that were things ideal, some proposition would be the case.1 What is important to the naïve view is not that these other senses of ‘ought’ do not exist, but rather that they are not exhaustive – for what they leave out, is the important deliberative sense of ‘ought’, which is the central subject of moral inquiry about what we ought to do and why – and it is this deliberative sense of ‘ought’ which the naïve view understands to express a relation between agents and actions.2 In contrast, logically and linguistically sophisticated philosophers – with a few notable exceptions3 – have rejected this naïve view. According to a dominant perspective in the interpretation of deontic logic and in linguistic semantics, for example, articulated by Roderick Chisholm (1964) and Bernard Williams (1981) in philosophy and in the dominant paradigm in linguistic semantics as articulated in particular by..

We propose a critique ofnormativism, defined as the idea that human thinking reflects a normative system against which it should be measured and judged. We analyze the methodological problems associated with normativism, proposing that it invites the controversial “is-ought” inference, much contested in the philosophical literature. This problem is triggered when there are competing normative accounts (the arbitration problem), as empirical evidence can help arbitrate between descriptive theories, but not between normative systems. Drawing on linguistics as a model, we (...) propose that a clear distinction between normative systems and competence theories is essential, arguing that equating them invites an “is-ought” inference: to wit, supporting normative “ought” theories with empirical “is” evidence. We analyze in detail two research programmes with normativist features – Oaksford and Chater's rational analysis and Stanovich and West's individual differences approach – demonstrating how, in each case, equating norm and competence leads to an is-ought inference. Normativism triggers a host of research biases in the psychology of reasoning and decision making: focusing on untrained participants and novel problems, analyzing psychological processes in terms of their normative correlates, and neglecting philosophically significant paradigms when they do not supply clear standards for normative judgement. For example, in a dual-process framework, normativism can lead to a fallacious “ought-is” inference, in which normative responses are taken as diagnostic of analytic reasoning. We propose that little can be gained from normativism that cannot be achieved by descriptivist computational-level analysis, illustrating our position with Hypothetical Thinking Theory and the theory of the suppositional conditional. We conclude that descriptivism is a viable option, and that theories of higher mental processing would be better off freed from normative considerations. (shrink)

This chapter focuses on one of the common fallacies in Western philosophy called the 'is/ought fallacy (IOF)'. Some philosophers conclude that the IOF is not a logical problem but an epistemological one, meaning that even if inferences like this one are logically valid, they cannot be used epistemologically to warrant anyone's real‐life moral beliefs. Arguments do not warrant their conclusions unless the premises of those arguments are themselves warranted, and in the real world, they say, no one would ever (...) be warranted in believing premise. Charles Pigden argues for the illegitimacy of the move from is to ought, saying that we should understand David Hume as pointing to the conservativeness of logic. According to Pigden, logic is conservative in that “the conclusions of a valid inference are contained within the premises. You do not get out what you have not put in”. (shrink)

Those who want to deny the ‘ought implies can’ principle often turn to weakened views to explain ‘ought implies can’ phenomena. The two most common versions of such views are that ‘ought’ presupposes ‘can’, and that ‘ought’ conversationally implicates ‘can’. This paper will reject both views, and in doing so, present a case against any pragmatic view of ‘ought implies can’. Unlike much of the literature, I won't rely on counterexamples, but instead will argue that (...) each of these views fails on its own terms. ‘Ought’ and ‘can’ do not obey the negation test for presupposition, and they do not obey the calculability or the cancelability tests for conversational implicature. I diagnose these failures as partly a result of the importance of the contrapositive of ‘ought implies can’. I end with a final argument emphasizing the role the principle plays in moral thinking, and the fact that no pragmatic account can do it justice. (shrink)

In this paper I present an argument for the claim that you ought to do something only if you may believe that you ought to do it. More exactly, I defend the following principle about normative reasons: An agent A has decisive reason to φ only if she also has sufficient reason to believe that she has decisive reason to φ. I argue that this principle follows from the plausible assumption that it must be possible for an agent (...) to respond correctly to her reasons. In conclusion, I discuss some implications of this argument (given that some other standard assumptions about reasons hold). One such implication is that we are always in a position to be justified in believing all truths about what we have decisive reason (or ought) to do. (shrink)

My primary purpose in this paper is to sketch a theory of doxastic oughts that achieves a satisfying middle ground between the extremes of rejecting epistemic deontology because one thinks beliefs are not within our direct voluntary control and rejecting doxastic involuntarism because one thinks that some doxastic oughts must be true. The key will be appreciating the obvious fact that not all true oughts require direct voluntary control. I will construct my account as an attempt to surpass other accounts (...) (especially those due to Feldman and Kornblith) in this vein. The new idea (in a telegraphic slogan) is that doxastic oughts are what Sellars called “rules of criticism,” which are logically distinct from but also interestingly connected to “rules of action.” The distinction provides a way to understand the phrase ‘ought to believe’ which is consistent with both doxastic involuntarism and epistemic deontology; the connection provides a novel way to incorporate a believer’s epistemic community into our understanding of the scope of epistemic obligations.

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 advances a reductive semantics for ‘ought’ and a naturalistic theory of normativity. It gives a unified analysis of predictive, instrumental, and categorical uses of ‘ought’: the predictive ‘ought’ is basic, and is interpreted in terms of probability. Instrumental ‘oughts’ are analyzed as predictive ‘oughts’ occurring under an ‘in order that’ modifer (the end-relational theory). The theory is then extended to categorical uses of ‘ought’: it is argued that they are special rhetorical uses of the (...) instrumental ‘ought’. Plausible conversational principles explain how this end-relational ‘ought’ can perform the expressive functions of the moral ‘ought’. The notion of an ‘ought-simpliciter’ is also discussed.

The subjective deontic "ought" generates counterexamples to classical inference rules like modus ponens. It also conflicts with the orthodox view about modals and conditionals in natural language semantics. Most accounts of the subjective ought build substantive and unattractive normative assumptions into the semantics of the modal. I sketch a general semantic account, along with a metasemantic story about the context sensitivity of information-sensitive operators.

Many of us feel internally conflicted in the face of certain normative claims that make infeasible demands: say, normative claims that demand that agents do what, given deeply entrenched objectionable character traits, they cannot bring themselves to do. On the one hand, such claims may seem false on account of demanding the infeasible, and insisting otherwise may seem to amount to objectionable unworldliness – to chasing “pies in the sky.” On the other hand, such claims may seem true in spite (...) of making infeasible demands, and insisting otherwise may seem to amount to treating the agents in question with undue lenience – to mistakenly letting them “off the hook.” What is going on? One possibility is that we are making a mistake. I explore the alternative hypothesis that our ambivalent reactions, far from involving any mistake, are entirely consistent and appropriate. Rather than some single privileged ought such that the idea that “ought” implies “feasible” is either true or false, there are simply different oughts that are supposed to be capable of operating in the service of, and playing distinct roles associated with, what I shall call different core normative practices. In particular, there is a) some salient core practice-serving ought for which it’s true that “ought” implies “feasible” and b) some other salient core practice-serving ought for which it’s false that “ought” implies “feasible.” I sketch a framework for understanding different core practice-serving oughts in general and then use this framework to consider which particular core practice-serving oughts might be capable of vindicating our ambivalence. I begin by considering and rejecting a prevalent and prima facie promising account according to which the relevant oughts are the prescriptive ought and the evaluative ought. I then propose a different account that holds that the oughts we need are instead the deliberative ought and the hypological ought. (shrink)

In Oughts and Thoughts, Anandi Hattiangadi provides an innovative response to the argument for meaning skepticism set out by Saul Kripke in Wittgenstein on ...

For the last 40 years or so the is/ought gap, the fact/value distinction and the naturalistic fallacy have figured prominently in ethical debates. This longevity, however, has had an adverse side effect. So familiar have they become that they—and their respective rationales—have tended to become blurred. It is the purpose of this paper to explain why they should be kept distinct.

This paper tests a theory about the relationship between two important topics in moral philosophy and psychology. One topic is the function of normative language, specifically claims that one “ought” to do something. Do these claims function to describe moral responsibilities, encourage specific behavior, or both? The other topic is the relationship between saying that one “ought” to do something and one’s ability to do it. In what respect, if any, does what one “ought” to do exceed (...) what one “can” do? The theory tested here has two parts: (1) “ought” claims function to both describe responsibilities and encourage people to fulfill them (the dual-function hypothesis); (2) the two functions relate differently to ability, because the encouragement function is limited by the person’s ability, but the descriptive function is not (the interaction hypothesis). If this theory is correct, then in one respect “ought implies can” is false because people have responsibilities that exceed their abilities. But in another respect “ought implies can” is legitimate because it is not worthwhile to encourage people to do things that exceed their ability. Results from two behavioral experiments support the theory that “ought” exceeds but implies “can.” Results from a third experiment provide further evidence regarding an “ought” claim’s primary function and how contextual features can affect the interpretation of its functions.

In this paper, I present the results of an experimental study on intuitions about moral obligation (ought) and ability (can). Many philosophers accept as an axiom the principle known as “Ought Implies Can” (OIC). If the truth of OIC is intuitive, such that it is accepted by many philosophers as an axiom, then we would expect people to judge that agents who are unable to perform an action are not morally obligated to perform that action. The results of (...) my experimental study show that participants were more inclined to judge that an agent ought to perform an action than that the agent can perform the action. Overall, participants said that an agent ought to perform an action even when they said that the agent cannot do it. I discuss the implications of these results for the debate over OIC. (shrink)

The syntactic structure of the deontic “ought” has been much debated in philosophy and linguistics. Schroeder argues that the deontic “ought” is syntactically ambiguous in the sense that it can be associated with either a control or raising construction. He distinguishes between deliberative and evaluative “ought”s and argues that the deliberative “ought” is control while the evaluative “ought” is raising. However, if there is a control sense of “ought,” it implies that there is a (...) sense of “ought” in which the word carries an external argument. Chrisman (2012) proposes two linguistic tests to verify this prediction. I add a new test, which I call the intensionality test, to the list. (shrink)

I motivate and characterize an intensional semantics for ‘ought’ on which it does not behave as a universal quantifier over possibilities. My motivational argument centers on taking at face value some standard challenges to the quantificational semantics, especially to the idea that ‘ought’-sentences satisfy the principle of Inheritance. I argue that standard pragmatic approaches to these puzzles are either not sufficiently detailed or unconvincing.

Most philosophers believe that a person can have an obligation only insofar as she is able to fulfil it, a principle generally referred to as “Ought Implies Can”. Arguably, this principle reflects something basic about the ordinary concept of obligation. However, in a paper published recently in this journal, Wesley Buckwalter and John Turri presented evidence for the conclusion that ordinary people in fact reject that principle. With a series of studies, they claimed to have demonstrated that, in people’s (...) judgements, obligations persist irrespective of whether those who hold them have the ability to fulfil them. We argue in this paper that due to some problems in their design, Buckwalter & Turri’s conclusions may not be war- ranted. We present the results of a series of studies demonstrating the problems with their design and showing that, with an improved design, people judge that obligation depends on ability after all.

According to the Ought-Implies-Can principle (OIC), an agent ought to perform a certain action only if the agent can perform that action. Proponents of OIC interpret this supposed implication in several ways. Some argue that the implication in question is a logical one, namely, entailment. Some think that the relation between ‘ought’ and ‘can’ is a relation of presupposition. Still others argue that ‘ought’ conversationally implicates ‘can’. Opponents of OIC offer a variety of counterexamples in an (...) attempt to show that there are cases in which an agent ought to perform a certain action even though she cannot perform that action. Such counterexamples often involve either culpable or nonculpable inability. In cases of culpable inability, the agent renders herself unable to fulfill an obligation. For example, a student is unable to submit a paper on the due date because she procrastinated until it became too late to write a paper by the assigned deadline. In cases of non-culpable inability, the agent somehow becomes unable to fulfill an obligation, through no fault of her own. For example, an agent becomes unable to pay back a loan to a bank because she was robbed on her way to the bank. This paper attempts to offer counterexamples to OIC of a sort different from the one discussed by opponents of OIC so far. If these counterexamples are correct, then they seem to suggest that there are cases in which an agent has an obligation to perform an action even though she may not be able to perform that action, and thus OIC is false. In other words, ‘ought’ does not imply ‘can’. (shrink)

Despite increasing prominence, ‘ought’-contextualism is regarded with suspicion by most metaethicists. As I’ll argue, however, contextualism is a very weak claim, that every metaethicist can sign up to. The real controversy concerns how contextualism is developed. I then draw an oft-overlooked distinction between “parochial” contextualism—on which the contextually-relevant standards are those that the speaker, or others in her environment, subscribe to—and “aspirational” contextualism—on which the contextually-relevant standards are the objective standards for the relevant domain. However, I argue that neither (...) view is acceptable. I suggest an original compromise: “ecumenical contextualism”, on which some uses of ‘ought’ are parochial, others aspirational. Ecumenical contextualism is compatible with realism or antirealism, but either combination yields interesting results. And though it’s a cognitivist view, it is strengthened by incorporating an expressivist insight: for robustly normative usages of ‘ought’, the contextually-relevant standards must be endorsed by the speaker.

Some philosophers hold that „ought‟ is ambiguous between a sense expressing a propositional operator and a sense expressing a relation between an agent and an action. We defend the opposing view that „ought‟ always expresses a propositional operator against Mark Schroeder‟s recent objections that it cannot adequately accommodate an ambiguity in „ought‟ sentences between evaluative and deliberative readings, predicting readings of sentences that are not actually available. We show how adopting an independently well-motivated contrastivist semantics for „ (...) class='Hi'>ought‟, according to which „ought‟ is always relativized to a contrast set of relevant alternatives, enables us to explain the evaluative-deliberative ambiguity and why the availability of these readings depends on sentential grammar.

I defend the following version of the ought-implies-can principle: (OIC) by virtue of conceptual necessity, an agent at a given time has an (objective, pro tanto) obligation to do only what the agent at that time has the ability and opportunity to do. In short, obligations correspond to ability plus opportunity. My argument has three premises: (1) obligations correspond to reasons for action; (2) reasons for action correspond to potential actions; (3) potential actions correspond to ability plus opportunity. In (...) the bulk of the paper I address six objections to OIC: three objections based on putative counterexamples, and three objections based on arguments to the effect that OIC conflicts with the is/ought thesis, the possibility of hard determinism, and the denial of the Principle of Alternate Possibilities.

According to a naive view sometimes apparent in the writings of moral philosophers, 'ought' often expresses a relation between agents and actions—the relation that obtains between an agent and an action when that action is what that agent ought to do. It is not part of this naive view that 'ought' always expresses this relation—adherents of the naive view are happy to allow that 'ought' also has an evaluative sense, on which it means, roughly, that were (...) things ideal, some proposition would be the case. What is important to the naive view is that there is also a deliberative sense of 'ought', on which it relates agents to actions. In contrast, logically and linguistically sophisticated philosophers have typically rejected this naive view. According to them, there is no argument-place for an agent in any relation expressed by 'ought', nor is there any argument-place for an action. According to this view, if Jim ought to jam, that is not because there is a special distinctive deliberative ought relation between Jim and jamming; rather, it is because a certain proposition ought to be the case: namely, that Jim jams. This essay defends the naive view, by first arguing that there are two distinct normative senses of 'ought', which actually exhibit different syntactic behavior, and then going on to argue that the deliberative sense of 'ought' relates agents to actions, rather than to propositions. It closes by drawing lessons for a range of issues in moral theory. (shrink)

This book examines three issues: the principle of ought implies can ; the principle of alternate possibilities ; and Kant’s views on the duty to promote one’s own happiness. It argues that although Kant was wrong to deny such a duty, the part of his denial that rests on a conception of duty incorporating both OIC and PAP is sound.

Some intuitive normative principles raise vexing 'detaching problems' by their failure to license modus ponens. I examine three such principles (a self-reliance principle and two different instrumental principles) and recent stategies employed to resolve their detaching problems. I show that solving these problems necessitates postulating an indefinitely large number of senses for 'ought'. The semantics for 'ought' that is standard in linguistics offers a unifying strategy for solving these problems, but I argue that an alternative approach combining an (...) end-relational theory of normativity with a comparative probabilistic semantics for 'ought' provides a more satisfactory solution.

This paper aims to contribute to the current debate about the status of the “Ought Implies Can” principle and the growing body of empirical evidence that undermines it. We report the results of an experimental study which show that people judge that agents ought to perform an action even when they also judge that those agents cannot do it and that such “ought” judgments exhibit an actor-observer effect. Because of this actor-observer effect on “ought” judgments and (...) the Duhem-Quine thesis, talk of an “empirical refutation” of OIC is empirically and methodologically unwarranted. What the empirical fact that people attribute moral obligations to unable agents shows is that OIC is not intuitive, not that OIC has been refuted. (shrink)

According to ‘ought’ implies ‘can’ (OIC), your obligation can never be to do what you cannot do. In a recent attack on OIC, Graham has argued that intuitions about justified intervention can help us determine whether the agent whose actions we use force to prevent would have acted permissibly or not. These intuitions, he suggests, cause trouble for the idea that you can be obligated to refrain from doing what you can refrain from doing. I offer a defense of (...) OIC and explain how non-consequentialists can accommodate his intuitions about his cases. (shrink)

A principle that many have found attractive is one that goes by the name “'Ought' Implies 'Can'.” According to this principle, one morally ought to do something only if one can do it. This essay has two goals: to show that the principle is false and to undermine the motivations that have been offered for it. Toward the end, a proposal about moral obligation according to which something like a restricted version of 'Ought' Implies 'Can' is true (...) is floated. Though no full-fledged argument for this proposal is offered, that it fits with a rather natural and intuitive picture of the structure of morality and seems to explain certain salient features of the debate over whether the principle is true, goes some way toward recommending it. (shrink)

In this paper, I argue that the “Ought Implies Can” (OIC) principle, as it is employed in epistemology, particularly in the literature on epistemic norms, is open to counterexamples. I present a counterexample to OIC and discuss several objections to it. If this counterexample works, then it shows that it is possible that S ought to believe that p, even though S cannot believe that p. If this is correct, then OIC, considered from an epistemic point of view, (...) is false, since it is supposed to hold for any S and any p. (shrink)

I report the results of a follow-up study, designed to address concerns raised by Kurthy and Lawford-Smith in response to my original study on intuitions about moral obligation (ought) and ability (can). Like the results of the original study, the results of the follow-up study do not support the hypothesis that OIC is intuitive. The results of both studies suggest that OIC is probably not a principle of ordinary moral cognition. As I have argued in my paper, I take (...) this to mean that OIC can no longer be taken as axiomatic. It must be argued for without appealing to intuitions. (shrink)

There are two central kinds of epistemological mistakes: believing things you shouldn’t, and failing to believe things that you should. The knowledge-first program offers a canonical explanation for the former: if you believe something without knowing it, you violate the norm to believe only that which you know. But the explanation does not extend in any plausible way to a story about what’s wrong with suspending judgment when one ought to believe. In this paper I explore prospects for a (...) knowledge-centering account of positive epistemic norms that describe epistemic duties to believe. (shrink)

In this paper, I demonstrate that Kant's commitment to an asymmetry between the control conditions for praise and blame is explained by his endorsement of the principle Ought Implies Can (OIC). I argue that Kant accepts only a relatively weak version of OIC and that he is hence committed only to a relatively weak requirement of alternate possibilities for moral blame. This suggests that whether we are transcendentally free is irrelevant to questions about moral permissibility and moral blameworthiness.

Suppose that it would be best if some set of people all did A, significantly worse if they all did B, and worst of all if some did A while some did B. Now suppose that they’re all going to do B, regardless of what the others do. It seems as though each of these people ought to pick B, given what the others are going to do. Yet it also seems as though something has gone wrong. This leads (...) to a puzzle: how can it be wrong for everyone to act as they ought? In this paper, I resolve this puzzle by arguing that there are joint ‘oughts’ which apply irreducibly to pluralities of agents, and which can pull in different directions to ‘oughts’ holding of given individuals; even if everyone individually ought to pick B, what they jointly ought to do is all pick A.

My main intention in presenting the “counter-examples” is to better understand Feldman’s evidentialism, and evidentialism in general.

There are many different oughts. There is a moral ought, a prudential ought, an epistemic ought, the legal ought, the ought of etiquette, and so on. These oughts can prescribe incompatible actions. What I morally ought to do may be different from what I self-interestedly ought to do. Philosophers have claimed that these conflicts are resolved by an authoritative ought, or by facts about what one ought to do simpliciter or all-things-considered. (...) However, the only coherent notion of an ought simpliciter has preposterous first-order normative commitments. It is more reasonable to reject the ought simpliciter in favor of the form of normative pluralism advocated in (Tiffany 2007). (shrink)

The aim of this article is twofold. First, it is argued that while the principle of ‘ought implies can’ is certainly plausible in some form, it is tempting to misconstrue it, and that this has happened in the way it has been taken up in some of the current literature. Second, Kant's understanding of the principle is considered. Here it is argued that these problematic conceptions put the principle to work in a way that Kant does not, so that (...) there is an important divergence here which can easily be overlooked.

According to epistemic deontologism, attributions of epistemic justification are deontic claims about what we ought to believe. One of the most prominent objections to this conception, due mainly to William P. Alston, is that the principle that ‘ought’ implies ‘can’ rules out deontologism because our beliefs are not under our voluntary control. In this paper, I offer a partial defense of Alston’s critique of deontologism. While Alston is right that OIC rules out epistemic deontologism, appealing to doxastic involuntarism (...) is not necessary for generating that tension. Deontologists would still have a problem with OIC if doxastic voluntarism turned out to be true or if deontologism did not require voluntarism. This is because, in short, epistemic justification does not imply ‘can’. If, as deontologists maintain, epistemic justification implies ‘oughts’, then epistemic justification must also imply ‘can’ given OIC. But since epistemic justification does not imply ‘can’, OIC dictates that we reject deontologism. I end by exploring the possible consequences of this incompatibility between OIC and deontologism. My conclusion is that at least one of the following claims must be true. Either ‘ought’ does not imply ‘can’, attributions of epistemic justification are not deontic claims, or epistemic claims lack necessary or categorical normative authority. (shrink)

l. There is an antinomy in Hare's thought between Ought-Implies-Can and No-Indicatives-from-Imperatives. It cannot be resolved by drawing a distinction between implication and entailment. 2. Luther resolved this antinomy in the l6th century, but to understand his solution, we need to understand his problem. He thought the necessity of Divine foreknowledge removed contingency from human acts, thus making it impossible for sinners to do otherwise than sin. 3. Erasmus objected (on behalf of Free Will) that this violates Ought-Implies-Can (...) which he supported with Hare-style ordinary language arguments. 4. Luther a) pointed out the antinomy and b) resolved it by undermining the prescriptivist arguments for Ought-Implies-Can. 5. We can reinforce Luther's argument with an example due to David Lewis. 6. Whatever its merits as a moral principle, Ought-Implies-Can is not a logical truth and should not be included in deontic logics. Most deontic logics, and maybe the discipline itself, should therefore be abandoned. 7. Could it be that Ought-Conversationally-Implies-Can? Yes - in some contexts. But a) even if these contexts are central to the evolution of Ought, the implication is not built into the semantics of the word; b) nor is the parallel implication built into the semantics of orders; and c) in some cases Ought conversationally implies Can, only because Ought-Implies-Can is a background moral belief. d) Points a) and b) suggest a criticism of prescriptivism - that Oughts do not entail imperatives but that the relation is one of conversational implicature. 8. If Ought-Implies-Can is treated as a moral principle, Erasmus' argument for Free Will can be revived (given his Christian assumptions). But it does not 'prove' Pelagianism as Luther supposed. A semi-Pelagian alternative is available. (shrink)

Every kind of ‘ought’ implies some kind of ‘can’ – but there are many kinds of ‘ought’ and even more kinds of ‘can’. In this essay, I shall focus on a particular kind of ‘ought’ – specifically, on what I shall call the “rational ‘ought’”. On every occasion of use, this kind of ‘ought’ is focused on the situation of a particular agent at a particular time; but this kind of ‘ought’ is concerned, not (...) with how that agent acts at that time, but with what beliefs or intentions the agent has at the time, or with the sort of reasoning by means of which the agent at that time forms or revises those beliefs or intentions.

Sometimes it is indeterminate what an agent morally ought do. This generates a Decision Ought Challenge—to give moral guidance to agents in such a scenario. This article is a field guide to the options for a theory of the decision ought for cases of indeterminacy. Three categories of view are evaluated, and the best representative for each is identified.

Some recent defenses of the 'ought' implies 'can' (OIC) principle try to derive that principle from uncontroversial claims about reasons for action. Reasons for action, it's said, are reasons only for 'potential' actions, which are actions that an agent can perform. Given that 'ought' implies 'reasons', it seems we have our proof of OIC. In this paper, I argue that this latest strategy for defending OIC fails.

The word 'ought' is one of the core normative terms, but it is also a modal word. In this book Matthew Chrisman develops a careful account of the semantics of 'ought' as a modal operator, and uses this to motivate a novel inferentialist account of why ought-sentences have the meaning that they have. This is a metanormative account that agrees with traditional descriptivist theories in metaethics that specifying the truth-conditions of normative sentences is a central part of (...) the explanation of their meaning. But Chrisman argues that this leaves important metasemantic questions about what it is in virtue of which ought-sentences have the meanings that they have unanswered. His appeal to inferentialism aims to provide a viable anti-descriptivist but also anti-expressivist answer to these questions. (shrink)

A thorny question surrounding the meaning of ought concerns a felt distinction between deontic uses of ought that seem to evaluate a state of affairs versus those that seem to describe a requirement or obligation to perform an action, as in and, respectively. There ought not be childhood death and disease. You ought to keep that promise. Various accounts have been offered to explain the contrast between “agentive” and “non-agentive” ought sentences. One such account is (...) the Agency-in-the-Prejacent theory, which traces the difference to a particular kind of ambiguity in the prejacent. This theory has been criticized as linguistically unviable. Indeed, I level a few novel complaints against AIP myself in the present paper. But AIP has a kernel of genuine insight which allows us to explain the contrast—that the distinction between agentive and non-agentive ought sentences owes in part to the way natural language encodes information about agency. I develop this idea into a novel account that, like AIP, traces the contrast to an ambiguity in the complement of the modal. However, according to the view I propose, the Coercion View, a linguistically-motivated coercion operation produces the necessary grammatical conditions for agentive ought, which in turn allow a kind of variadic function operator in the style of to produce the semantic effect we see on display in agentive readings of ought. Having explained the mechanism by which we get this structure, I show that it corroborates some of the central intuitions underwriting agentive ought. I submit that the Coercion View offers an explanation of agentive ought to take at least as seriously as any of its competitors. (shrink)

Ethical theorists often assume that the verb ‘ought’ means roughly ‘has an obligation’; however, this assumption is belied by the diversity of ‘flavours’ of ought-sentences in English. A natural response is that ‘ought’ is ambiguous. However, this response is incompatible with the standard treatment of ‘ought’ by theoretical semanticists, who classify ‘ought’ as a member of the family of modal verbs, which are treated uniformly as operators. To many ethical theorists, however, this popular treatment in (...) linguistics seems to elide an important distinction between agential and non-agential ought-statements. The thought is that ‘ought’ must have at least two senses, one implicating agency and connected to obligations, and another covering other uses. In this paper, I pursue some resolution of this tension between semantic theory and ethical theory with respect to the meaning of ‘ought’. To this end, I consider what I believe to be the most linguistically sophisticated argument for the view that the word ‘ought’ is ambiguous between agential and non-agential senses. This argument, due to Mark Schroeder, is instructive but based on a false claim about the syntax of agential ought-sentences—or so I attempt to show by first situating Schroeder's argument in its proper linguistic background and then discussing some syntactic evidence that he fails to appreciate. Then, I use the failure of this argument to motivate some more general reflections on how the standard treatment of ‘ought’ by theoretical semanticists might be refined in the light of the distinction important to ethical theory between agential and non-agential ought-statements, but also on how ethical theory might benefit from more careful study of the dominant treatment of modals as operators in theoretical semantics.

The moral principle that Ought Implies Can (“OIC”) is often assumed without argument in normative discourse. Is this assumption defensible? Some would argue that it is not, as there are many purported counterexamples against it in the literature. However, OIC is not so much a single principle as rather a family of them. In this paper, I will argue that, while not every OIC-type principle is defensible, at least one of them may be. I defend the cognate moral principle (...) that Ought Implies Can or Could Have (“OICCH”). I first show that it is able to circumvent the traditional counterexamples to OIC. And then I show that OICCH is even more plausible than some of the best alternative OIC-type principles to date. The upshot of this paper is that those who find OIC compelling should consider accepting OICCH instead. (shrink)

Hume seems to claim that there does not exist a valid argument that has all non-ethical sentences as premises and an ethical sentence as its conclusion. Starting with Prior, a number of counterexamples to this claim have been proposed. Unfortunately, all of these proposals are controversial. Even the most plausible have a premise that seems like it might be an ethical sentence or a conclusion that seems like it might be non-ethical. Since it is difficult to tell whether any of (...) these counterexamples are genuine, we need a taxonomy that sorts out ethical sentences from non-ethical ones. We need to know the difference between an ‘Is’ and an ‘Ought’. In the first part of the paper, I establish the need for a taxonomy. I consider some of the most influential ‘Is’–‘Ought’ derivations. These include proposals by Prior and Searle. I argue that each proposal has a premise whose status as ethical or non-ethical is difficult to determine. In the second part of the paper, I consider taxonomies proposed by Karmo and Maitzen. I argue against both taxonomies. I end with the claim that we need a taxonomy of ethical sentences and that none of the current proposals are adequate. (shrink)
