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.

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

Competing metaethical theories are sometimes cast as alternative ways of responding to an inconsistency between two apparent features of moral judgments, viz., that they are truth-apt expressions of belief and that they have motivational force. I argue that this is an oversimplification that fails to address some important data that can be accommodated on the basis of a straightforward “good reasons” account of “ought” judgments that explains why certain of these judgments have motivational force will others do not. This (...) solution applies equally to all “ought” judgments regardless of whether they are advanced from the moral point of view, so it is not threatened by the existence of amoralists or moral nihilists. And it does not in its own right involve a commitment to any particular metaethical theory. This shows that the problem of motivation does not provide a good framework for the major metaethical debates. (shrink)

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)

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.

Ought Implies Kant defends Kantianism via a critical examination of consequentialism. The latter is shown to be untenable on epistemic grounds; meanwhile, the charge that Kantianism is really consequentialism in disguise is refuted. The book also presents a novel interpretation of Kantianism as according direct duties owed to other animals.

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.

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)

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 book offers brief examination and analysis of fundamental moral terms constituting ethical theories while proposing clarifications of them. It consequently considers whether the three major ethical theories - Teleology, Deontology, and Utilitarianism - adequately explain human conduct and humans' propensity to seek happiness given these theories' notions of the latter. After brief exposition of recognized and less known problems with each of the theories' projects, the book offers new and improved definition of happiness which accommodates these theories' important claims (...) and notions of happiness while addressing some of the objections to defining happiness as living a good life or contemplation, duty, and experiencing pleasure. The book concludes with a defense of morality as a necessary component of human life and the idea that we must engage in the pursuit of happiness ethically. (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.

This book is a major work in the history of ethics, and provides the first study of early modern British philosophy in several decades. Professor Darwall discerns two distinct traditions feeding into the moral philosophy of the seventeenth and eighteenth centuries. On the one hand, there is the empirical, naturalist tradition, comprising Hobbes, Locke, Cumberland, Hutcheson, and Hume, which argues that obligation is the practical force that empirical discoveries acquire in the process of deliberation. On the other hand, there is (...) a group including Cudworth, Shaftesbury, Butler, and in some moments Locke, which views obligation as inconceivable without autonomy and which seeks to develop a theory of the will as self-determining.

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)

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)

Are we able to do everything we ought to do? According to the important but controversial Ought Implies Can principle, the answer is yes. -/- In this book Alex King sheds some much-needed light on this principle. She argues that it is flawed because we are obligated to perform some actions that we cannot perform, and goes on to present a suggested theory for anyone who would deny the principle. She examines the traditional motivations for Ought Implies (...) Can, and finds that they to a large degree do not support it. Using examples like gay rights, addiction, and disability, she argues that we can preserve many of the motivations that led us to the principle by thinking more about what we, as individuals or institutions, can fairly demand of ourselves and each other.

Leda Cosmides and John Tooby have some advice for moral philosophers and deontic logicians trying to understand deontic notions like ought: give up trying to provide a univocal, domain-general treatment. The domain-specific character of human cognition means that such a research program is probably fruitless and probably pointless. It is probably fruitless, since a univocal account of the meaning of "ought" will not capture the multiple inferential patterns of deontic reasoning exhibited in different contexts (and similarly for lots (...) of other words like "obligation," "entitlement," etc. - but let’s stick with "ought"). And it is probably pointless, because even if a domain general logic can be developed, it will "fail to capture major distinctions the human mind makes when reasoning deontically" (ms 5). As a result, it is "not likely to be widely understood and adopted" so it will "not succeed in guiding ethical decisions beyond an esoteric circle of specialists" (ms 5). (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)

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.

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.

The principle, Ought implies can, Has two versions. The strong version expresses a necessary condition for the appropriateness of moral judgments; the weak version expresses a possible ground for excusing wrongdoing. The strong version is presupposed by choice-Morality, While the weak one is presupposed by character-Morality. It is argues that the strong version and choice-Morality are mistaken and that the weak version and character-Morality give a much more plausible account of our moral experience. The general conclusion is that choice (...) is not necessary for the appropriateness of moral disapproval. (shrink)

We tend to think every ought statement implies that an actual agent can comply. However, our uses of “ought” suggest that some ought statements fail to have this implication: it is possible that the actual agent ought to do something she has no chance of accomplishing even if she intends to do so. Rather they imply that if the agent and her circumstances were defect-free, she could and would perform the prescribed action. There are two types (...) of evaluation for ought statements. One type of evaluation addresses the question of what to do given the agent’s peculiar capacity and condition. The point of this evaluation is giving personalized action guidance, and so recommends only what the actual agent can do under the actual condition. Another type of evaluation addresses a different question, that of what to do as a type of agents. The point of this evaluation is the coordination of individuals by selecting a shared norm for them: the standard that prescribes all of them to perform the same action and classifies for all of them the same traits as defect. This is why it endorses the ought statements that some actual agents cannot comply with, but that a normal agent could and would do so under normal conditions. (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)

In this paper I distinguish moral “ought”-judgments, meaning “ought”- judgments that qualify as moral judgments, from “morally ought”-judgments, meaning “ought”-judgments whose “ought” is either prefaced (or followed) by the word “morally” or construable as so prefaced. Specifically, I argue that the former class of judgments is wider than the second. (As I show in section 3, this is not to argue for the already familiar distinction, or putative distinction, between a broad and a narrow sense (...) of “moral.”) I also speculate as to why the distinction exists, and, more important, show that it has important consequences. For instance, it undermines a tempting argument for moral subjectivism. (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.

Research that is integrated into ongoing clinical activities holds the potential to accelerate the generation of knowledge to improve the health of individuals and populations. Yet integrating research into clinical care presents difficult ethical and regulatory challenges, including how or whether to obtain informed consent. Multiple empirical studies have explored patients' and the public's attitudes toward approaches to consent for pragmatic research. Questions remain, however, about how to use the resulting empirical data in resolving normative and policy debates and what (...) kind of data warrants the most consideration. We recommend prioritizing data about what people consider acceptable with respect to consent for pragmatic research and data about people's informed, rather than initial, preferences on this subject. In addition, we advise caution regarding the weight given to majority viewpoints and identify circumstances when empirical data can be overridden. We argue that empirical data bolster normative arguments that alterations of consent should be the default in pragmatic research; waivers are appropriate only when the pragmatic research would otherwise be impracticable and has sufficiently high social value.

We propose a critique of normativism, 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)

Ali comparative studies imply simultaneously an identity and a difference, a situation that is replete with intellectual difficulties which give rise to interminable disputes regarding whether we are talking about the same thing or different things. One may cut the gordian knot by deciding either way, but the situation would reappear again as it is bound up with the comparative perspective itself and not with any particular example of it. How long shall we go on “naming”, for the process is (...) unending and ultimately “everything is what it is. and not another thing”. Or, if we do not like “names” as they hardly give us any knowledge and if we opt for “description” which gives us “facts”, then they too are as unending as the “names”, for, as the Jains taught us long ago, they are a function of the dṛṣti that we have or the point of view that we adopt.

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)

Encyclopedia article on the meaning of 'ought'.

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)

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)

The concept of missed care refers to an irrefragable truth that required nursing care, which is left undone, occurs in the delivery of health care. As a technical concept, missed care offers nurses the opportunity to articulate a problematic experience. But what are we to make of missed care from an ethical perspective? Can nurses be held morally responsible for missed care? Ethically speaking, it is generally accepted that if a person has a moral obligation to do something, s/he needs (...) to have the capacity to do it. If a person does not have the capacity to fulfil a moral obligation, then s/he cannot be held responsible for failing to do so. This is captured by the “ought implies can” (OIC) principle. This paper brings the OIC principle to the forefront of the discussion on missed care. It is contended that nurses – qua moral agents – may be discharged from a moral obligation to carry out a required caring act because of some inability that is not of their making and therefore may not be morally responsible for missed care. However, the OIC principle may not be applied to all situations of missed care depending on their causes. In addition, following in the thought of Sapontzis (The Southern Journal of Philosophy, 1991, XXIX, 383–393) it is contended that when an original obligation to deliver a required act of care cannot be fulfilled, other obligations may be generated as summed up in the “Principle of Making Amends” and the “Principle of Appropriate Feeling.” It is the view of this paper that these further principles could prevent the OIC principle from being used to simply excuse omissions of care from a normative standard and could support the view that nurses continue to have alternative obligations to make amends and to respond with appropriate feelings to missed care.

Elizabeth Anscombe's paper ‘Modern Moral Philosophy’ 1 seems clearly to have failed in its task. Kurt Baier describes the paper as ‘widely discussed and much admired’ 2 and Peter Winch has called one of its three theses ‘enormously influential’ 3 within moral philosophy.

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.

Given the current organ shortage, a prevalent alternative to the altruism-based policy is a market-based solution: pay people for their organs. Receiving much popular and scholarly attention, a salient normative argument against neoliberal pressures is the preservation of human dignity. This article examines how advocates of both the altruistic status quo and market challengers reason and weigh the central normative concept of dignity, meant as inherent worth and/or rank. Key rhetorical strategies, including motivations and broader social visions, of the two (...) positions are analyzed and evaluated, and the separation of morally normative understandings of dignity from market encroachment is defended.

In Making Sense of Free Will and Moral Responsibility Dana Nelkin defends the “rational abilities view.” According to this view, agents are responsible for their behavior if and only if they act with the ability to recognize and act for good reasons. It follows that agents who act well are open to praise regardless of whether they could have acted differently, but agents who act badly are open to blame only if they could have acted on the moral reasons that (...) counted against their behavior. I summarize the main themes of Nelkin’s theory of responsibility and offer reasons for rejecting the claim that agents are blameworthy only if they could have responded to moral considerations. It is true that wrongdoers who could not have responded appropriately to moral considerations are often excused from blame, but I argue that not all the forms that such incapacity can take will furnish grounds for excuse. In other words, some circumstances that entail that a wrongdoer cannot respond to moral considerations are compatible with that agent fulfilling conditions that are sufficient for moral responsibility.

The word ought is often used to express moral judgments. It is used to express moral laws, as in “We ought to honour our parents”; and it is used to express singular moral judgments, as in “You ought not to have spoken to your mother like that”". Some singular moral judgments are clearly deductions from some moral law, as is “You ought not to have spoken to your mother like that”. Others, however, are not clearly so, (...) e.g. “You ought not to have done that”. Where both the agent and the action are indicated merely by a contextual reference, no underlying moral law is suggested by the words alone. Even when the singular judgment characterizes both the agent and the action, as “You, being a strong man, ought to have gone to his aid”, it may still be quite obscure what, if any, moral law implies this judgment. Clearly there is no moral law that “Every strong man ought always to go to everybody's aid”. (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)

Schurz draws on modern alethic- deontic predicate logic to address the venerable yet enduring problem of whether what ought to be can be derived from what is.

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.

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)

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.

I investigate collective intentionality (CI) through the “Ought” implies “Can” (OIC) principle. My leading question is does OIC impose any further requirement on CI?

In the last part of the paper, I put forward an (inverted) Hartian framework to allow the Searlean CI theory to be agent sensitive and cope (...) with the problems that emerged. (shrink)
