Justification is potential knowledge

This paper will articulate and defend a novel theory of epistemic justification; I characterize my view as the thesis that justification is potential knowledge (JPK). My project is an instance of the ‘knowledge-first’ programme, championed especially by Timothy Williamson. So I begin with a brief recapitulation of that programme.     

Reasons and practical possibility

According to a common thesis about normative reasons for action, you have a reason to perform a given action only if you can act for that reason. This thesis has long had broad appeal and is intended to capture the practical character of practical reasons. I’ll call it the ‘Practicality Thesis’. Recently, however, various writers have developed subtly different objections to it, each designed to show that there can be actions you have a reason to perform even though you could not act for that reason – because, were you aware of the reason-giving facts in the ways needed to act for the reason, it would no longer be a reason for you to so act. This article defends the Practicality Thesis against such objections. It considers some extant defences but shows that these are inadequate. It then advances an alternative approach intended to counter any structurally similar objection.     

In Defense of a Broad Conception of Experimental Philosophy

Experimental philosophy is often presented as a new movement that avoids many of the difficulties that face traditional philosophy. This article distinguishes two views of experimental philosophy: a narrow view in which philosophers conduct empirical investigations of intuitions, and a broad view which says that experimental philosophy is just the colocation in the same body of (i) philosophical naturalism and (ii) the actual practice of cognitive science. These two positions are rarely clearly distinguished in the literature about experimental philosophy, both pro and con. The article argues, first, that the broader view is the only plausible one; discussions of experimental philosophy should recognize that the narrow view is a caricature of experimental philosophy as it is currently done. It then shows both how objections to experimental philosophy are transformed and how positive recommendations can be provided by adopting a broad conception of experimental philosophy.     

Justifying Desires

According to an influential conception of reasons for action, the presence of a desire or some other conative state in the agent is a necessary condition for the agent's having a reason for action. This is sometimes known as internalism. This article presents a case for the considerably stronger thesis, which we may call hyper‐internalism, that the presence of a desire is a sufficient condition for the agent's having a (prima facie) reason for action.     

Alternative motivation: a new challenge to moral judgment internalism

Internalists argue that there is a necessary connection between motivation and moral judgment. The examination of cases plays an important role in philosophical debate about internalism. This debate has focused on cases concerning the failure to act in accordance with a moral judgment, for one reason or another. I call these failure cases. I argue that a different sort of case is also relevant to this debate. This sort of case is characterized by (1) moral judgment and (2) behavior that accords with the content of the moral judgment but that has been performed not because of the moral judgment. Instead it is due to some other source of motivation. I call these alternative motivation cases. I distinguish two sorts of alternative motivation cases, and I argue that externalists have natural explanations of these cases. By contrast, extant internalist accounts of failure cases are inadequate when applied to alternative motivation cases.     

Psychopathy and internalism

Do psychopaths make moral judgments but lack motivation? Or are psychopaths’ judgments are not genuinely moral? Both sides of this debate seem to assume either externalist or internalist criteria for the presence of moral judgment. However, if moral judgment is a natural kind, we can arrive at a theory-neutral criterion for moral judgment. A leading naturalistic criterion suggests that psychopaths have an impaired capacity for moral judgment; the capacity is neither fully present nor fully absent. Psychopaths are therefore not counterexamples to internalism. Nonetheless, internalism is empirically problematic because it is unable to explain psychopaths’ moral deficits.     

Weakness of will and motivational internalism

The unconditional version of motivational internalism says that if an agent sincerely judges that to φ in circumstances C is the best option available to her, then, as a matter of conceptual necessity, she will be motivated to φ in C. This position faces a powerful counterargument according to which it is possible for various cases of practical irrationality to completely defeat an agent’s moral motivation while, at the same time, leaving her appreciation of her moral reasons intact. In this paper, I will argue that weakness of will, as the paradigmatic case of practical irrationality, and all other cases of practical irrationality that feature in standard formulations of this argument do not represent genuine counterexamples to this version of motivational internalism. In this sense, the main aim of this paper is to show that proponents of this internalist position are well justified in their denial of the claim that there are people who are completely unmotivated by their judgments about what is the best option available to them.     

Practical Reasons, Practical Rationality, Practical Wisdom

There are a number of proposals as to exactly how reasons, ends and rationality are related. It is often thought that practical reasons can be analyzed in terms of practical rationality, which, in turn, has something to do with the pursuit of ends. I want to argue against the conceptual priority of rationality and the pursuit of ends, and in favor of the conceptual priority of reasons. This case comes in two parts. I first argue for a new conception of ends by which all ends are had under the guise of reasons. I then articulate a sense of rationality, procedural rationality, that is connected with the pursuit of ends so conceived, where one is rational to the extent that one is motivated to act in accordance with reasons as they appear to be. Unfortunately, these conceptions of ends and procedural rationality are inadequate for building an account of practical reasons, though I try to explain why it is that the rational pursuit of ends generates intuitive but misleading accounts of genuine normative reasons. The crux of the problem is an insensitivity to an is-seems distinction, where procedural rationality concerns reasons as they appear, and what we are after is a substantive sense of rationality that concerns reasons as they are. Based on these distinct senses of rationality, and some disambiguation of what it is to have a reason, I offer a critique of internalist analyses of one’s reasons in terms of the motivational states of one’s ideal, procedurally rational self, and I offer an alternative analysis of one’s practical reasons in terms of practical wisdom that overcomes objections to related reasons externalist views. The resulting theory is roughly Humean about procedural rationality and roughly Aristotelian about reasons, capturing the core truths of both camps.
