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 answering the challenge inside a Searlean framework, I realize that we need to clarify what CI's structure is and what kind of role the agents joining a CI-act have. 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)

칸트의 의무 · 능력 원리에 따르면, 의무는 능력을 함축한다. 다시 말해 우리가 어떤 행위를 해야 하는 의무가 있다는 것은 우리가 그 행위를 할 수 있음을 함축한다. 이 원리는 매우 오랫동안 당연한 것으로 간주되어 왔다. 그렇지만 최근 이 원리는 철학자들 사이에 큰 논란거리이다. 대표적으로 라이언과 펠드먼에 따르면 이 원리는 거짓이다. 이 논문에서 필자는 의무 · 능력 원리를 책임의 면제조건과 관련하여 이해함으로써 이 원리에 대해 지금껏 제기돼 온 여러 비판들을 물리칠 수 있음을 주장한다. 또한 올스턴의 반의지주의 논변이 옳지 않는 이유가, 라이언과 펠드먼의 (...) 주장과 달리 의무 · 능력 원리가 거짓이기 때문이 아님을 주장한다.

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

Recently David Widerker argued that from the widely accepted ought implies can principle one can deduce the controversial and much discussed principle of alternative possibilities (PAP). Actually, he argues that this result is true only of the part of PAP which deals with moral blame. Because there are acts of supererogation, he maintains that it does not apply to the part which deals with moral praise. What Widerker says about supererogation seems true, and I develop and (...) expand upon this idea in the first half of the paper. Then I argue that Widerker's argument regarding moral blame fails.

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.

This essay argues against the commonly held view that "ought" implies "can" in the domain of morality. More specifically, I contest the notion that nobody should ever be held morally responsible for failing to avoid the infliction of any harm that he or she has not been able to avoid through all reasonably feasible precautions in the carrying out of some worthwhile activity. The article explicates the concept of a moral right in order to show why violations of (...) moral rights can occur even when no one has acted wrongfully in any fashion. In so doing, it will effectively be maintaining that strict liability (i.e., liability irrespective of the presence or absence of culpability) exists in morality as well as in law. When we take account of the distinction between exoneration and extenuation, we can see that scrupulously thorough precautions are never sufficient to constitute an excuse in morality. Having made that point with some extended examples, the article goes on to consider a number of possible objections - objections that lead into discussions of some basic distinctions within moral philosophy and some central principles within deontic logic.

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.

It is a dominant dictum in ethics that ‘ought implies can’ (OIC): if an agent morally ought to do an action, the agent must be capable of performing that action. Yet, with current technological developments, such as in direct-to-consumer genomics, big data analytics and wearable technologies, there may be reasons to reorient this ethical principle. It is our modest aim in this article to explore how the current wave of allegedly disruptive innovation calls for a renewed (...) interest for this dictum. As an effect of prevention and prediction oriented technological innovation, an increased focus on assumedly controllable lifestyle risks may be anticipated. For lay people who might turn into patients, this may entail a reinforced behavior-based individual responsibilisation. Holding on to the OIC dictum, such responsibilisation seems to require that individuals can actually control what is framed as ‘lifestyle risks’ when there is not always a reliable consensus about what one should do. As such, reference to OIC may be mobilised in function of a political task of designing institutions so as to enable such choice and control. (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. (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)

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)

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.

This paper examines two contexts in ethical theory that some have thought support the claim that attempts, rather than actions, are what are morally required of agents. In each context there is an appeal to the principle that 'ought' implies 'can'. I begin by explaining how I think appeals to this principle typically work. I conclude that not only do the contexts in question not demonstrate that moral requirements range over attempts, but also that any argument (...) in support of that conclusion has serious obstacles to overcome. (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)

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.

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.

To argue that “ought” implies “can,” one can appeal to general principles or to intuitions about specific cases. One general truism that seems to show that “ought” implies “can” is that obligations must be able to guide action, and putative obligations that are unfulfillable are unable to do so. This paper argues that obligations that are unfulfillable can still guide action, and that moral theories which reject the principle that “ought” implies “can” are (...) actually better able to account for how obligations guide than theories which endorse “ought” implies “can.” The paper also argues that any intuitions about specific cases that seem to provide evidence that “ought” implies “can” do not actually give us this evidence. Rather, these intuitions pose similar problems for theories which accept “ought” implies “can” as they pose for theories which reject the principle. Some theories which reject “ought” implies “can” will fit our intuitions at least as well, if not better, than theories which accept it. So, intuitions do not favor accepting that “ought” implies “can,” and appeal to general principles favors its denial. (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.

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 (...) class='Hi'>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)

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)

It is widely thought that moral obligations are necessarily guidance giving. This supposed fact has been put to service in defence of the ‘ought-implies-can’ principle according to which one cannot be morally obligated to do the impossible, since impossible-to-satisfy obligations would not give guidance. It is argued here that the supposed fact is no such thing; moral obligations are not necessarily guiding giving, and so the ‘guidance argument’ for ought-implies-can fails. This is the result of (...) no non-trivial condition being ‘luminous’. (shrink)

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)

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)

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

The principle “Ought implies can” has important connections with the problem of free will. In this chapter, I lay out these connections and proceed to consider a recent exercise in “experimental philosophy” whose results some have regarded as constituting an important challenge to the principle. Although many, perhaps most, philosophers regard the principle as an analytic truth, a survey of non-philosophers conducted in 2016 has led its authors to conclude that non-philosophers do not accept the (...) “Ought implies can” principle. The main topics of this chapter are a critical evaluation of the authors’ interpretation of the results of their survey and an examination of the implications of those results for the question whether the principle is true.

ABSTRACT:In this article we investigate a philosophical problem for normative business ethics theory suggested by a phenomenon that contemporary psychologists call “bounded ethicality,” which can be identified with the putative fact that well-intentioned people, constrained by psychological limitations, make ethical choices inconsistent with their own ethical beliefs and commitments. When one combines the idea that bounded ethicality is pervasive with the idea that a person morally ought to do something only if she can, it raises a doubt about the (...) practical relevance of the moral principles that business ethics theory prescribes. We call this doubt the Radical Behavioral Challenge. It consists in the idea that people cannot generally conform to the normative ethical principles that business ethics theorists prescribe, and that these principles are therefore practically irrelevant. We answer the Radical Behavioral Challenge and explore normative implications of our answer. (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)

Although Kant is often considered the founding father of the controversial principle ‘Ought Implies Can’ (OIC), it is not at all clear how Kant himself understands and defends this principle. This essay provides a substained interpretation of Kant's views on OIC. I argue that Kant endorses two versions of OIC: a version that is concerned with our physical capacities, and a version that posits a link between moral obligation and a volitional power of choice. I show (...) that although there are important senses in which Kant's conception of OIC differs from the way in which OIC is discussed in recent philosophy, his account raises important issues for contemporary theory: for instance, it highlights the extent to which acceptance or rejection of OIC reflects convictions about the sources of normativity.

In Morals from Motives, Michael Slote proposed an agent-based approach to virtue ethics in which the morality of an action derives solely from the agent’s motives. Among the many objections that have been raised against Slote’s account, this article addresses two problems associated with the Kantian principle that ought implies can. These are the problems of “deficient” and “inferior” motivation. These problems arise because people cannot freely choose their motives. We cannot always choose to act from good (...) motives; nor can we always avoid acting from bad ones. Given this, Slote’s account implies that we sometimes cannot do what we ought to do, contrary to Kant’s principle. In this article, I propose an alternative agent-based account which, I argue, circumvents these problems. While people cannot choose their motives, they can choose their intentions. By characterizing virtuous action, as I do, in terms of good intentions rather than in terms of good motives, the conflict between what people can do and what they ought to do is resolved. (shrink)

While philosophers generally accept some version of the principle ‘ought’ implies ‘can’, recent work in experimental philosophy and cognitive science provides evidence against a presupposition or a conceptual entailment from ‘ought’ to ‘can’. Here, we review some of this evidence, its effect on particular formulations of the principle, and future directions for cognitive scientists and philosophers.

Most philosophers assume that ‘ought’ implies ‘can’, and most of them hold that this principle is true not only universally but also analytically or conceptually. Some skeptics deny this principle, although they often admit some related one. In this article, we show how new empirical evidence bolsters the skeptics’ arguments. We then defend the skeptical view against some objections to the empirical evidence and to its effect on the traditional principle. In light of the new (...) evidence, we conclude that philosophers should stop unconditionally assuming that ‘ought’ implies ‘can’. (shrink)

Deontological evidentialism is the claim that S ought to form or maintain S’s beliefs in accordance with S’s evidence. A promising argument for this view turns on the premise that consideration c is a normative reason for S to form or maintain a belief that p only if c is evidence that p is true. In this paper, I discuss the surprising relation between a recently influential argument for this key premise and the principle that ought (...) class='Hi'>implies can. I argue that anyone who antecedently accepts or rejects this principle already has a reason to resist either this argument’s premises or its role in support of deontological evidentialism. (shrink)

I argue that Fischer’s attempts to undermine the “Ought” Implies “Can” principle (OIC) fail. I argue both against his construal of the natural motivation for OIC and against his argument for the falsity of OIC. I also consider some attempts to salvage Fischer’s arguments and argue that they can work only if the true moral theory is motive determinative--i.e., it is such that, necessarily, any action performed from a motive which renders one of the blame emotions appropriate (...) is morally impermissible, no matter what other features it has. But, as motive-determinative moral theories are implausible, Fischer’s arguments are not salvageable. (shrink)

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

I will attempt to do two things in this paper.In Part I) I will show that H.A. Prichard failed to appreciate the limitations of the application of the ‘“ought” implies “can”’ principle. Where the ‘can’ is not the ‘can’ of physical impossibility the principle is false; the principle can be shown to be false when it is read this way by an examination of the role of excuses, which is not that of removing obligations. Part (...) II) demonstrates how the misapplication of the ‘“ought” implies “can”’ principle is utilized in a chain of confusion: a confusion of excuses and justifications with respect to obligations and a confusion of the relation between obligations and blameworthiness. (shrink)

My paper has two aims: to underscore the importance of differently time-indexed ‘ought implies can’ principles; and to apply this to the culpable inability problem. Sometimes we make ourselves unable to do what we ought, but in those cases, we may still fail to do what we ought. This is taken to be a serious problem for synchronic ‘ought implies can’ principles, with a simultaneous ‘ought’ and ‘can’. Some take it to support diachronic (...) ‘ought implies can’, with a potentially temporally distinct ‘ought’ and ‘can’. I will argue that this problem is not avoided by diachronic ‘ought implies can’. (shrink)

A standard principle in ethics is that moral obligation entails ability, or that “ought implies can”. A strong case has been made that this principle is not well motivated in moral psychology. This paper presents an analogous case against the theoretical motivation for the principle. The principle is in tension with several foundational areas of ethical theorizing, including research on apologies, excuses, promises, moral dilemmas, moral language, disability, and moral agency. Across each of these (...) areas, accepting the principle that obligation entails ability creates a theoretical problem that is more easily solved by rejecting it rather than accepting it. I conclude that the motivation for the principle is weak and that “ought implies can” should be rejected in ethics on theoretical grounds. (shrink)

Recently, psychologists have explored moral concepts including obligation, blame, and ability. While little empirical work has studied the relationships among these concepts, philosophers have widely assumed such a relationship in the principle that “ought” implies “can,” which states that if someone ought to do something, then they must be able to do it. The cognitive underpinnings of these concepts are tested in the three experiments reported here. In Experiment 1, most participants judge that an agent (...) class='Hi'>ought to keep a promise that he is unable to keep, but only when he is to blame for the inability. Experiment 2 shows that such “ought” judgments correlate with judgments of blame, rather than with judgments of the agent’s ability. Experiment 3 replicates these findings for moral “ought” judgments and finds that they do not hold for nonmoral “ought” judgments, such as what someone ought to do to fulfill their desires. These results together show that folk moral judgments do not conform to a widely assumed philosophical principle that “ought” implies “can.” Instead, judgments of blame play a modulatory role in some judgments of obligation. (shrink)

In moral dilemmas, where circumstances prevent two or more equally justified prima facie ethical requirements from being fulfilled, it is often maintained that, since the agent cannot do both, conjoint obligation is overridden by Kant's principle that ought implies can, but that the agent nevertheless has a disjunctive obligation to perform one of the otherwise obligatory actions or the other. Against this commonly received view, it is demonstrated that although Kant's ought-can principle may avoid logical (...) inconsistency, the principle is incompatible with disjunctive obligation in standard deontic logic, and that it entails paradoxically that none of the conflicting dilemma actions will in fact occur. The principle appears to provide the only plausible safeguard against deontic antinomy, but cannot be admitted because of its collision with considered moral judgments. (shrink)

Frances Howard -Snyder has argued that objective consequentialism violates the principle that ‘ought’ implies ‘can’. In most situations, she claims, we cannot produce the best consequences available, although objective consequentialism says that we ought to do so. Here I try to show that Howard -Snyder's argument is unsound. The claim that we typically cannot produce the best consequences available is doubtful. And even if there is a sense of ‘producing the best consequences’ in which we cannot (...) do so, objective consequentialism does not entail that we ought, in this sense, to produce the best consequences.

Undergraduate students of philosophy are often told that Kant is famous for teaching us that “ought implies can,” and furthermore that this principle implies that it makes no sense to tell someone that they ought to do something if they do not have the ability to execute the action in question. It is thus surprising to find that the words “ought implies can” do not appear conspicuously in popular English translations of Kant’s main (...) moral philosophical texts (such as the Groundwork, and Critique of Practical Reason). I argue that Kant’s writings do not clearly support it, and at points stand opposed to it. One may still attribute the formula “ought implies can” to Kant, but only at the cost of understanding this formula in a nonstandard manner. (shrink)

This volume responds to the growing interest in finding explanations for why moral claims may lose their validity based on what they ask of their addressees. Two main ideas relate to that question: the moral demandingness objection and the principle "ought implies can." Though both of these ideas can be understood to provide an answer to the same question, they have usually been discussed separately in the philosophical literature. The aim of this collection is to provide a (...) focused and comprehensive discussion of these two ideas and the ways in which they relate to one another, and to take a closer look at the consequences for the limits of moral normativity in general. Chapters engage with contemporary discussions surrounding "ought implies can" as well as current debates on moral demandingness, and argue that applying the moral demandingness objection to the entire range of normative ethical theories also calls for an analysis of its presuppositions. The contributions to this volume are at the leading edge of ethical theory, and have implications for moral theorists, philosophers of action, and those working in metaethics, theoretical ethics and applied ethics.

Many interpreters use Hobbes’s endorsement of “ought implies can” to justify treating Hobbes’s motivational psychology as an external constraint on his normative theory. These interpreters assume that, for Hobbes, something is “possible” for a person to do only if they can be motivated to do it, and so Hobbes’s psychological theory constrains what obligations people have. I argue this assumption about what is “possible” is false and so these arguments are unsound. Looking to Hobbes’s exchange with Bramhall on (...) free will, I argue that the sense of “possible” relevant for “ought implies can” in Hobbes’s philosophy only concerns an agent’s capacity to do something if they decide to do it. Whether a person can be motivated to do something, then, does not determine if it is possible for them. Consequently, Hobbes’s motivational psychology cannot determine what our obligations are by invoking the principle that “ought implies can.”. (shrink)
