A response to Christopher Preston's book "Grounding Knowledge" (2003). I first argue that Preston’s work strongly suggests that epistemologists would do well to re-examine and pay greater attention to ‘knowledge how’. Second, I briefly consider several of Preston’s proposals (concerning the importance of place to our cognitive lives) through the lens of contemporary virtue epistemology and suggest how Preston’s work might inform and shape theorizing in this area. Finally, I turn to a set of potential questions for Preston, focusing in particular on his proposal that we ought to preserve a wide range of places inorder to allow for an epistemically valuable cognitive diversity.

I argue that recent virtue theories (including those of Hursthouse, Slote, and Swanton) face important initial difficulties in accommodating the supererogatory. In particular, I consider several potential characterizations of the supererogatory modeled upon these familiar virtue theories (and their accounts of rightness) and argue that they fail to provide an adequate account of supererogation. In the second half of the paper I sketch an alternative virtue-based characterization of supererogation, one that is grounded in the attitudes of virtuous ideal observers, and that avoids the concerns raised in the first part of the paper.

It is argued that Nozick's experience machine thought experiment does not pose a particular difficulty for mental state theories of well-being. While the example shows that we value many things beyond our mental states, this simply reflects the fact that we value more than our own well-being. Nor is a mental state theorist forced to make the dubious claim that we maintain these other values simply as a means to desirable mental states. Valuing more than our mental states is compatible with maintaining that the impact of such values upon our well-being lies in their impact upon our mental lives.

In this paper I argue (i) that choosing to abide by realist moral norms would be as arbitrary as choosing to abide by the mere preferences of a God (a difficulty akin to the Euthyphro dilemma raised for divine command theorists); in both cases we would lack reason to prefer these standards to alternative codes of conduct. I further develop this general line of thought by arguing in particular (ii) that we would lack any noncircular justification to concern ourselves with any such realist normative standards.

My central thesis is that philosophers considering questions of epistemic value ought to devote greater attention to the enduring nature of beliefs. I begin by arguing that a commonly drawn analogy between beliefs and actions is flawed in important respects, and that a better, more fruitful analogue for belief would be desire, or a similarly enduring state of an agent. With this in hand, I argue that treating beliefs as enduring, constitutive states of agents allows us to capture the importance of accessible, justified, and true beliefs to sustaining personal identity, autonomy, self-control, and authenticity. We thus arrive at a significant value to such beliefs through their crucial role in our personal, practical identities.
