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.

Does ?ought? imply ?can? for collectives' obligations? In this paper I want to establish two things. The first, what a collective obligation means for members of the collective. The second, how collective ability can be ascertained. I argue that there are four general kinds of obligation, which devolve from collectives to members in different ways, and I give an account of the distribution of obligation from collectives to members for each of these kinds. One implication of understanding collective obligation and (...) ability in the proposed way is that a group can be blameworthy for failing to realize its obligation even when no member of the group is blameworthy for failing to realize her obligation.

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.

A type of transcendental argument for libertarian free will maintains that if acting freely requires the availability of alternative possibilities, and determinism holds, then one is not justified in asserting that there is no free will. More precisely: if an agent A is to be justified in asserting a proposition P (e.g. "there is no free will"), then A must also be able to assert not-P. Thus, if A is unable to assert not-P, due to determinism, then A is not (...) justified in asserting P. While such arguments often appeal to principles with wide appeal, such as the principle that ‘ought’ implies ‘can’, they also require a commitment to principles that seem far less compelling, e.g. the principle that ‘ought’ implies ‘able not to’ or the principle that having an obligation entails being responsible. It is argued here that these further principles are dubious, and that it will be difficult to construct a valid transcendental argument without them. (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.

Moral obligation, according to one influential conception, is distinct among other moral concepts in at least two respects. First, obligation is linked with demands. If I am obligated to you to do X, then you can demand that I do X. Second, obligation is linked with blame and the rest of our accountability practices. If I am obligated to you to do X, failure to do so is blameworthy and you may hold me accountable for it. The puzzle is the (...) following: when it comes to our attitudes, in particular to our emotional responses, these two components seem to come apart. We do not appear to demand that others feel a given emotion. And yet, we do blame others (and ourselves) for feeling them. The challenge I take on in this paper is to sort out the moral status of emotions given these facts. (shrink)

This is a defense of John Stuart Mill’s proof of the principle of utility in the fourth chapter of his Utilitarianism. The proof is notorious as a fallacious attempt by a prominent philosopher, who ought not to have made the elementary mistakes he is supposed to have made. This book shows that he did not. The aim is not to glorify utilitarianism, in a full sweep, as the best normative ethical theory, or even to vindicate, on a more specific level, (...) Mill’s universalistic ethical hedonism as the best form of utilitarianism. The book is concerned only with Mill’s utilitarianism, and primarily with his proof of the principle of utility. The purpose is to show that Mill proceeds intelligibly and systematically in pursuing a well-defined project in the fourth chapter of Utilitarianism, and that he successfully defends what he sets out to establish in his proof of the principle of utility.

From an indeterminist's perspective, I support and defined the following argument for deontic incompatibilism: If determinism is true, then no one ever can do otherwise than he does. If no one ever can do otherwise than he does, then nothing anyone does is ever right, wrong, or obligatory. Therefore, if determinism is true, then nothing anyone does is ever right, wrong, or obligatory. ;They sense of 'can' I use in this argument is what I call "the power-'can' of ordinary language." (...) The power-'can' has two time indexes; one applies to the power itself, the other to the relevant doing. I argue that the power-'can' is a sense of 'can' with which the "ought implies can" principle holds true. ;I review and respond to various accounts of 'can' proposed by compatibilists Bruce Aune, Keith Lehrer, David Lewis, G. E. Moore and others. Elsewhere I discuss writings by Peter van Inwagen and J. L. Austin. ;To support , I utilize, argue for, and show the advantages of the Temporal Physical Possibility Requirements: If an agent, S, can at time T do A at time T$\sp\prime$, then S's doing A at $T\sp\prime$ is jointly possible with the conjunction of the state of the world at T and the laws of nature. When arguing for these requirements, I focus on how most people use the power-'can' and how they would use it in various situations. I present and respond to objections to my arguments. Most of the objections are based on certain strong forms of contextualism. ;I argue for and defend my premises against various objections. One objection is based on a form of utilitarianism advocated by Fred Feldman. Other objections are based on an example by Harry Frankfurt concerning moral responsibility. ;Two arguments against are presented and I respond. They are developed from a suggestion by John Martin Fischer that people would continue making deontic claims if a consortium of scientists were to find strong evidence of determinism. (shrink)
