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)

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)

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)

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)

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.

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)

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.

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)

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.

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)

In the classic Miners case, an agent subjectively ought to do what they know is objectively wrong. This case shows that the subjective and objective ‘oughts’ are somewhat independent. But there remains a powerful intuition that the guidance of objective ‘oughts’ is more authoritative—so long as we know what they tell us. We argue that this intuition must be given up in light of a monotonicity principle, which undercuts the rationale for saying that objective ‘oughts’ are an authoritative guide for (...) agents and advisors. (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)

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)

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.

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. (shrink)

What does logic tells us how about we ought to reason? If P entails Q, and I believe P, should I believe Q? I will argue that we should embed the issue in an independently motivated contextualist semantics for ‘ought’, with parameters for a standard and set of propositions. With the contextualist machinery in hand, we can defend a strong principle expressing how agents ought to reason while accommodating conflicting intuitions. I then show how our judgments about blame and guidance (...) can be handled by this machinery. (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)

Scepticism about ought simpliciter is the view that there is no such thing as what one ought simpliciter to do. Instead, practical deliberation is governed by a plurality of normative standpoints, each authoritative from their own perspective but none authoritative simpliciter. This paper aims to resist such scepticism. After setting out the challenge in general terms, I argue that scepticism can be resisted by rejecting a key assumption in the sceptic’s argument. This is the assumption that standpoint-relative ought judgments bring (...) with them a commitment to act in accordance with those judgments. Instead, I propose an alternative account of our normative concepts according to which only ought simpliciter judgments commit one to acting in accordance with those judgments. In addition to answering the sceptical challenge, the proposal offers an independently motivated account of what makes a concept normatively authoritative. (shrink)

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)

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)

This paper argues that the innovation of an ordering source parameter in the standard Lewis-Kratzer semantics for modals was a mistake, at least for English auxiliaries like ‘ought’, and that a simpler dyadic semantics (as proposed in my earlier work) provides a superior account of normative uses of modals. I programmatically investigate problems arising from (i) instrumental conditionals, (ii) gradability and “weak necessity”, (iii) information-sensitivity, and (iv) conflicts, and show how the simpler semantics provides intuitive solutions given three basic moves: (...) (1) an end-relational analysis of normative modality, (2) a “most” analysis of “weak necessity”, and (3) well-motivated appeals to pragmatics. I conclude with metasemantic observations about the desiderata for a semantics for ‘ought’. (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.

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.

This is a short response to Sybille Schmidt's paper (in the same volume) "Is There an Ethics of Forgetting?". The response starts out by admitting that forgetting is an essential function of human existence, that it serves, as it were, an important evolutionary function: that it is good, since it contributes to our well-being, to have the ability to forget. But this does not give us as answer, affirmative or not, to Schmidt’s title question: “Is There an Ethics of Forgetting?” (...) The main impediment to answering this question, certainly to answering it in the affirmative, seems to be a problem that Schmidt mentions but does not in the end tackle head on: the question whether we can willfully forget – or, for that matter, remember – our own or others' past deeds. For if we cannot forget even what we will to forget, then, by the so-called "ought implies can" principle, no obligations (or even permissions) arise for us to forget (or remember) anything. The rest of the response spells out four possible ways of tackling this problem, ultimately arguing that, given the advances in medicine, it might well become possible - and to some extent it is already possible - to forget what we will to forget.

Haji argues that determinism threatens deontic morality, not via a threat to moral responsibility, but directly, because of the principle that ‘ought’ implies ‘can’. Haji’s argument requires not only that we embrace an ‘ought’ implies ‘can’ principle, but also that we adopt the principle that ‘ought’ implies ‘able not to’. I argue that we have little reason to adopt the latter principle, and examine whether deontic morality might be destroyed on the basis of the more commonly embraced ‘ought’ implies ‘can’ (...) principle alone. I argue that despite what look like initially compelling reasons why we might suppose that this weaker conclusion is similarly destructive to deontic morality, we actually have good reason to doubt that it has any practical relevance for moral deliberation at all.

This paper draws a distinction between ‘right MacIntyreans’ who are relatively optimistic that MacIntyre’s vision of ethics can be realised in capitalist society, and ‘left MacIntyreans’ who are sceptical about this possibility, and aims to show that the ‘left MacIntyrean’ position is a promising perspective available to business ethicists. It does so by arguing for a distinction between ‘community-focused’ practices and ‘excellence-focused’ practices. The latter concept fulfils the promise of practices to provide us with an understanding of the best work (...) for humankind and highlights the affinities between MacIntyre’s concept of a practice and Marx’s conception of good work as free, creative activity. The paper concludes with a suggestion that we reflect on the best forms of work so that we can strive to ensure the very best activities, those most consonant with our flourishing, one day become available to all.

The is-ought gap is Hume’s claim that we can’t get an ‘ought’ from just ‘is’s. Prior (“The Autonomy of Ethics,” 1960) showed that its most straightforward formulation, a staple of introductory philosophy classes, fails. Many authors attempt to resurrect the claim by restricting its domain syntactically or by reformulating it in terms of models of deontic logic. Those attempts prove to be complex, incomplete, or incorrect. I provide a simple reformulation of the is-ought gap that closely fits Hume’s description of (...) it. My formulation of the gap avoids the proposed counterexamples from Prior and offers a natural explanation of why they seem compelling. Moreover, I show that my formulation of the gap is guaranteed by standard theories of the semantics of normative terms, and that provides a more general reason to accept it. (shrink)

This paper concerns the semantic difference between strong and weak neces-sity modals. First we identify a number of explananda: their well-known in-tuitive difference in strength between ‘must’ and ‘ought’ as well as differ-ences in connections to probabilistic considerations and acts of requiring and recommending. Here we argue that important extant analyses of the se-mantic differences, though tailored to account for some of these aspects, fail to account for all. We proceed to suggest that the difference between ’ought’ and ’must’ lies (...) in how they relate to scalar and binary standards. Briefly put, must(φ) says that among the relevant alternatives, φ is selected by the relevant binary standard, whereas ought(φ) says that among the relevant al-ternatives, φ is selected by the relevant scale. Given independently plausi-ble assumptions about how standards are provided by context, this ex-plains the relevant differences discussed. (shrink)

Utilitarianism has often been understood as a theory that concerns itself first and foremost with the rightness of actions; but many other things are also properly subject to moral evaluation, and utilitarians have long understood that the theory must be able to provide an account of these as well. In a landmark article from 1976, Robert Adams argues that traditional act utilitarianism faces a particular problem in this regard. He argues that a on a sensible utilitarian account of the rightness (...) of an agent’s motives, right motives will sometimes conflict with right actions, leaving the theory internally incoherent. The puzzle Adams raises has received a good deal of attention but few proposed solutions. Fred Feldman, however, has offered a solution that seems to be gaining adherents. In this paper I argue that Feldman’s approach cannot succeed. At bottom, it relies on a version of the principle that ‘ought’ implies ‘can’—and subsequently an account of an agent’s alternatives—that is far too restrictive to be plausible. Despite the failure of this solution, however, I argue that the conflict Adams develops is not as theoretically troubling as he suggests. While traditional act utilitarianism may fail for other reasons, it will not fail due to the conflict between acts and motives. (shrink)

Focusing mainly on Meinong’s "Über emotionale Präsentation" and Veber’s "Die Natur des Sollens", I examine their respective conceptions of ought. Meinong has not written a specific work on the ought, he deals with it as a part of his value theory. In "Über emotionale Präsentation" the ought is a property of being, which cannot be viewed as separated from a desiring subject. The ought is an ideal object of higher order; it concerns neither factuality nor non-factuality, but subfactuality, that is (...) the realm of possibility. In "Die Natur des Sollens", Veber proposes a structured theory of ought, which is grounded on Meinongian concepts. The ought is the object of a volition, it is a genuine object, even though ideal. I conclude by portraying the differences between Veber's and Meinong's conceptions of the ought. (shrink)

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.

According to the principle that ‘ought’ implies ‘can’, it is never the case that you ought to do something you cannot do. While many accept this principle in some form, it also has its share of critics, and thus it seems desirable if an argument can be offered in its support. The aim of this paper is to examine a particular way in which the principle has been defended, namely, by appeal to considerations of fairness. In a nutshell, the idea (...) (due to David Copp) is that moral requirements we cannot comply with would be unfair, and there cannot be unfair moral requirements. I discuss several ways of spelling out the argument, and argue that all are unsatisfactory for a variety of reasons. (shrink)

Defenders of the Kantian maxim, i.e. ‘ought’ implies ‘can’, defend the maxim taking the term “implication” in the sense of ‘entailment’. But if it is granted that “implication” means entailment, then it can be shown that the Kantian maxim that ‘ought’ implies ‘can’ is false. Sinnott-Armstrong attempts to prove the falsity of the maxim by his argument from Self-Imposed Impossibility in which he offers his famous example of Adams. But Sinnott-Armstrong’s example of Adams appears to be not strong enough to (...) prove the falsity of the maxim; it is a subject to be captured by a version of the maxim, namely the Maxim-KT. That is why two new examples of the argument from Self-Imposed Impossibility are presented in this paper which are stronger and are able to prove the falsity of the Kantian maxim. (shrink)

Morality, it is commonly argued, cannot be extreme in the demands it makes of us, because “ought” implies “can”, and normal human psychology places limits on the extent to which most of us are capable of devoting our lives to the service of others. To evaluate this argument, we need to distinguish different uses of “ought” and “can”. Having distinguished these uses, we find that there is more than one defensible version of the principle that “ought” implies “can”. However, these (...) distinctions can also be deployed to show that the attempt to argue from this principle to the conclusion that morality cannot be extremely demanding fails. (shrink)

The moral error theory generally does not receive good press in metaethics. This paper adds to the bad news. In contrast to other critics, though, I do not attack error theorists’ characteristic thesis that no moral assertion is ever true. Instead, I develop a new counter-argument which questions error theorists’ ability to defend their claim that moral utterances are meaningful assertions. More precisely: Moral error theorists lack a convincing account of the meaning of deontic moral assertions, or so I will (...) argue. (shrink)

William Alston’s argument against epistemological deontologism rests upon two key premises: first, that we lack a suitable amount of voluntary control with respect to our beliefs, and, second, the principle that “ought” implies “can.” While several responses to Alston have concerned rejecting either of these two premises, I argue that even on the assumption that both premises are true, there is room to be made for deontologism in epistemology. I begin by offering a criticism of Richard Feldman’s invaluable work on (...) ‘role-oughts’, whereupon I development my own positive view in light of Feldman’s shortcomings. The upshot is that while we as epistemic agents are not responsible for the beliefs we form, we are nonetheless responsible for the various bodily or mental activities that typically bear a causal influence on belief formation.

Hume seems to contend that you can’t get an ought from an is. Searle professed to prove otherwise, deriving a conclusion about obligations from a premise about promises. Since (as Schurz and I have shown) you can’t derive a substantive ought from an is by logic alone, Searle is best construed as claiming that there are analytic bridge principles linking premises about promises to conclusions about obligations. But we can no more derive a moral obligation to pay up from the (...) fact that a promise has been made than we can derive a duty to fight a duel from the fact that a challenge has been issued – just conclusions about what we ought to do according to the rules of the relevant games. Hume suggests bridge principles that would take us from the rules of the games to conclusions about duties, but these principles are false. My argument features an obstreperous earl, an anarchist philosopher and a dueling Prime Minister. (shrink)

This paper focuses on the Enkratic principle of rationality, according to which rationality requires that if an agent sincerely and with conviction believes she ought to X, then X-ing is a goal in her plan. We analyze the logical structure of Enkrasia and its implications for deontic logic. To do so, we elaborate on the distinction between basic and derived oughts, and provide a multi-modal neighborhood logic with three characteristic operators: a non-normal operator for basic oughts, a non-normal operator for (...) goals in plans, and a normal operator for derived oughts. We prove two completeness theorems for the resulting logic, and provide a dynamic extension of the logic by means of product updates. We illustrate how this setting informs deontic logic by considering issues related to the filtering of inconsistent oughts, the restricted validity of deontic closure, and the stability of oughts and goals under dynamics.

Die meisten Philosophen stimmen darin überein, dass Kant sich dem Prinzip „Sollen impliziert Können“, bzw. „ought implies can“ (OIC), verschrieben hat. Allerdings sind sich nur wenige darüber einig, wie die Bedeutung von OIC zu verstehen ist. Außerhalb der Kant-Wissenschaft gibt es Debatten über die Bedeutung von „sollen“, die Bedeutung von „impliziert“ und die Bedeutung von „können“ in diesem Prinzip. Innerhalb der Kant-Forschung besteht kein Konsens darüber, was Kant zu diesen Themen dachte. In diesem Artikel versuche ich, diese Situation zu verbessern. (...) In Abschnitt I überprüfe ich die Sekundärliteratur zu Kants Engagement für OIC und erkläre, wo die Interpretation meiner Meinung nach schief geht. In Abschnitt II untersuche ich einige der direkten Textbeweise dafür, dass Kant eine bestimmte Version von OIC zugeschrieben wird. In Abschnitt III lege ich dar, was meiner Meinung nach die wichtigsten doktrinären Gründe dafür sind, Kant diese Version von OIC zuzuschreiben. (shrink)

It is almost an epistemological platitude that the goal of inquiry is to pursue truth-acquisition and falsity-avoidance. But further reflection on this dual goal of inquiry reveals that the two (sub)goals are in tension because they are inversely proportionate: the more we satisfy the one (sub)goal the less we satisfy the other and vice versa. I elaborate the inverse proportionality point in some detail and bring out its puzzling implications about the normative question of what one ought to believe. As (...) I argue, given the tension between the two (sub)goals, the problem of the correct regulation of belief-fixation pops to the surface. Call this ‘the James problem’ in tribute to William James who first drew attention to the problem. As a response ‘to the James Problem’, I sketch the contours of a solution to the problem that involves the rather neglected epistemic concepts of understanding and wisdom and links these concepts with the goal of eudaimonia (or living well). The resultant theory constitutes an approach to epistemic normativity that makes little use of the traditional epistemic concepts of truth and knowledge that have historically dominated the field of epistemology.

Many take the claim that you cannot ‘get’ an ‘ought’ from an ‘is’ to imply that non- moral beliefs are by themselves incapable of justifying moral beliefs. I argue that this is a mistake and that the position that moral beliefs are justified exclusively by non-moral beliefs—a view that I call moral inferentialism—presents an attractive non-sceptical moral epistemology.

According to typical ought-implies-can principles, if you have an obligation to vaccinate me tomorrow, then you can vaccinate me tomorrow. Such principles are uninformative about conditional obligations: what if you only have an obligation to vaccinate me tomorrow if you synthesize a vaccine today? Then maybe you cannot vaccinate me tomorrow ; what you can do instead, I propose, is make it the case that the conditional obligation is not violated. More generally, I propose the ought-implies-can-obey principle: an agent has (...) an obligation only at times at which the agent can obey the obligation. I also propose another principle, which captures the idea that ‘ought’ implies ‘can avoid’. I defend both principles mainly by arguing that they help explain why agents lose obligations, including conditional ones. (shrink)

Thomas Schmidt argues that a widely held combination of views about reasons and ought—the Balancing View of Ought and the claim that reasons against Q are reasons for not-Q—is extensionally adequate only if it is complemented by two principles of reasons transmission. In this paper I present three problems for Schmidt’s package of views and two problems for his transmission principles considered in isolation. I then defend a rival package of views—a version of the Balancing View and the claim that (...) reasons against Q are reasons that bear on Q with negative weight—that avoids these problems and secures extensional adequacy without Schmidt’s principles. I conclude that friends of the Balancing View should prefer my package of views. (shrink)

n ‘Modern Moral Philosophy’ Anscombe argues that the moral ‘ought’ should be abandoned as the senseless survivor from a defunct conceptual scheme. I argue 1) That even if the moral ‘ought’ derives its meaning from a Divine Law conception of ethics it does not follow that it cannot sensibly survive the Death of God. 2) That anyway Anscombe is mistaken since ancestors of the emphatic moral ‘ought’ predate the system of Christian Divine Law from which the moral ‘ought’ supposedly derives (...) its meaning (Cicero in particular subscribed to something like the modern conception of a duty which seems to be a generalization of the duties attendant on particular roles). 3) That if the moral ‘ought’ derived its meaning from embodying Gods’ commands then the two should have been equated in the minds of true believers. This was not the case. 4) That Anscombe is absurdly wrong in supposing that Protestant moralists had abandoned a Divine Law conception of ethics. 5) That the virtue-based ought-free Aristotelian alternative suggested by Anscombe is unworkable since the basic idea is that it pays in terms of human flourishing to be good (which means inter alia being just). Since it is pretty obvious that there are plenty of good people who don’t flourish and flourishing people who are not good, the neo-Aristotelian program has gradually undergone a degenerating problem-shift: either the pay-off is deferred to the hereafter or being good is incorporated into the pay-off. 6) That there is a certain amount of sophistry in selling the neo-Aristotelian virtues. Since the unjust person is simply somebody who is NOT systematically just, you cannot prove that it pays to be just by arguing that it is a mistake to be systematically UNjust. So too for many of the other virtues. (shrink)

How are we to understand the intentionality of desire? According to the two classical views, desire is either a positive evaluation or a disposition to act. This essay examines these conceptions of desire and argues for a deontic alternative, namely the view that desiring is representing a state of affairs as what ought to be. Three lines of criticism of the classical pictures of desire are provided. The first concerns desire’s direction of fit, i.e. the intuition that the world should (...) conform to our desires. The second concerns the “death of desire” principle, i.e. the intuition that one cannot desire what one represents as actual. The last pertains to desire’s role in psychological explanations, i.e. the intuition that desires can explain motivations and be explained by evaluations. Following these criticisms, three positive arguments in favor of the deontic conception are sketched. (shrink)

STIT logic is a prominent framework for the analysis of multi-agent choice-making. In the available deontic extensions of STIT, the principle of Ought-implies-Can (OiC) fulfills a central role. However, in the philosophical literature a variety of alternative OiC interpretations have been proposed and discussed. This paper provides a modular framework for deontic STIT that accounts for a multitude of OiC readings. In particular, we discuss, compare, and formalize ten such readings. We provide sound and complete sequent-style calculi for all of (...) the various STIT logics accommodating these OiC principles. We formally analyze the resulting logics and discuss how the different OiC principles are logically related. In particular, we propose an endorsement principle describing which OiC readings logically commit one to other OiC readings. (shrink)

In 1935, the Nazi government introduced what came to be known as the abrogation of the pro- hibition of analogy. This measure, a feature of the new penal law, required judges to stray from the letter of the written law and to consider instead whether an action was worthy of pun- ishment according to the ‘sound perception of the people’ and the ‘underlying principle’ of existing criminal statutes. In discussions of Nazi law, an almost unanimous conclusion is that a system (...) of criminal law ought not to contain legislation of this sort. This conclusion is often based on how the abro- gation relates to the normative claim that the law ought to be predictable. In particular, it has been argued that since the law ought to be predictable, and since this type of analogy legis- lation implied, caused or contributed to the diminution of the law’s predictability, this type of legislation ought to be prohibited. In this paper, we argue that this argument is not entirely correct. While we believe that the law ought to be predictable and that there is evidence for the claim that the Nazis’ intro- duction of analogical reasoning implied, caused, or contributed to a diminution of predictability, this fact is logically too weak to ground the conclusion that necessarily a penal system ought not to contain legislation of this kind. Despite the undeniable wickedness of the Nazi penal system, this type of analogical reasoning can be made consistent with the pre- dictability of the law. We argue that consistency of this sort depends on whether the use of analogy is supplemented by certain contextual background conditions. The occurrence of these conditions blocks an inference from the fact that the law ought to be predictable to the conclusion that a penal system ought not to allow for this type of analogical reasoning.

Are John Rawls’s most noticeable methodological contributions, reflective equilibrium and the original position, consistent with each other? I draw attention to a worry that they stand in inconsistent relationships to the claim that ought implies can: it can only be the case that we ought to do something if we can do it.

Knows-knows principles in epistemology say that if you know some proposition, then you are in a position to know that you know it. This paper examines the viability of analogous principles in ethics, which I call ought-ought principles. Several epistemologists have recently offered new defences of KK principles and of other related principles, and there has recently been an increased interest in examining analogies between ethics and epistemology, and so it seems natural to examine whether defences of KK and related (...) principles carry over to OO principles. In this paper, I introduce two OO principles, and I show how some arguments in favour of KK carry over to them. Then I show how these OO principles can be used to shed light on a much-discussed case in ethics, that of Professor Procrastinate. (shrink)
