Reasons for Action and Psychological Capacities

Most moral philosophers agree that if a moral agent is incapable of performing some act ф because of a physical incapacity, then they do not have a reason to ф. Most also claim that if an agent is incapable of ф-ing due to a psychological incapacity, brought about by, for example, an obsession or phobia, then this does not preclude them from having a reason to ф. This is because the ‘ought implies can’ principle is usually interpreted as a claim about physical, rather than psychological, capacities. In this paper I argue for an opposing view: if we don’t have reasons to do things that we are physically incapable of doing, then neither do we have reasons to do things we are psychologically incapable of doing. I also argue that extending the ‘ought implies can’ principle to psychological capacities makes the principle more attractive.     

Practical Skepticism and the Reasons for Action

There is nearly universal agreement that coercion is an evil. Even when it is necessary to avoid a greater evil or to attain some good, it is still a necessary evil. There is also nearly universal agreement that, other things being equal, one ought not to exercise coercion. Here the agreement ends. There is little agreement about just when coercion is justified. More surprisingly, there is little agreement about what coercion is. This latter controversy is more fundamental, and this paper is an attempt to shed some light on it.     

Reasons

The temptation to look for the “purely normative essence” of argument stems from the understandable ambition to distinguish rational persuasion from mere persuasion. But in seeking a purely normative notion of argument it is easy to overlook—or actually deny—that rational persuasion is a kind of persuasion. The burden of this essay is to show that the concept of reason from which our interest in argument derives can only exist and have normative force as a kind of persuasion, that is, as something (also) causal.

     

Justifying Reasons, Motivating Reasons, and Agent Relativism in Ethics

According to agent relativism, each person's moral requirements are relative to her desires or interests. That is, whether a person morally ought to depends on what interests or desires she has. Some philosophers charge that the main argument for agent relativism trades on an ambiguity –specifically, an ambiguity in ``reason,' ``reasonfor action,' or a kindred term. This charge has been common, and widely thought to damage the case for agent relativism, since its appearance, in 1958, in a now classic paper by William Frankena. In what follows I examine the charge in detail, showing that insofar as it aims to discredit the argument for agent relativism, it fails in its purpose.     

Objective Reasons

In order to establish that judgments about practical reasons can be objective, it is necessary to show that the applicable standards provide an adequate account of truth and error. This in turn requires that these standards yield an extensive set of substantive, publicly accessible judgments that are presumptively true. This output requirement is not satisfied by the standards of universalizability, consistency, coherence, and caution alone. But it is satisfied if we supplement them with the principle that desire is a source of minimal reasons. This principle is justified despite currently fashionable arguments against the claims of desire.     

Subjective Reasons

In recent years, the notion of a reason has come to occupy a central place in both metaethics and normative theory more broadly. Indeed, many philosophers have come to view reasons as providing the basis of normativity itself . The common conception is that reasons are facts that count in favor of some act or attitude. More recently, philosophers have begun to appreciate a distinction between objective and subjective reasons, where (roughly) objective reasons are determined by the facts, while subjective reasons are determined by one's beliefs. My goal in this paper is to offer a plausible theory of subjective reasons. Although much attention has been focused on theories of objective reasons, very little has been offered in the literature regarding what sort of account of subjective reasons we should adopt; and what has been offered is rather perfunctory, and requires filling-out. Taking what has been said thus far as a starting point, I will consider several putative theories of subjective reasons, offering objections and amendments along the way, will settle on what I take to be a highly plausible account, and will defend that account against objections.     

Volatile Reasons

I argue for the existence of a category of practical reasons which I call ‘Deliberation-Volatile Reasons’ or ‘DVRs’. DVRs have the distinguishing feature that their status as reasons for action is diminished when they are weighed in deliberation by the agent. I argue that DVRs are evidence of ‘deliberative blind spots’. I submit that an agent manifests a peculiar kind of practical irrationality in so far as she endeavours to find a deliberative path to what she has reason to do, when the discovery of such a path renders the destination inaccessible.
