Polyfacetic epistemology would answer the skeptic, provide how-to-think manuals, explain how we know, and more. To some it is the project of assuring oneself, of validating one's knowledge or supposed knowledge, turning it into real and assured knowledge, thus defeating the skeptic. To others it is a set of rules or instructions, a guide to the perplexed, a manual for conducting the intellect. To others yet it is a meta-discipline, but one whose purpose is not nearly so much guidance as understanding, understanding of what gives us the knowledge we do have, of what factors serve to justify so many of our beliefs well enough to make them knowledge. What follows is epistemology as understanding, an attempt to understand the relation between epistemic coherence and intellectual virtue at the foundation of epistemology: between the comprehensive coherence prized in the thirst for understanding and the "reliability" that makes a faculty or procedure intellectually virtuous.

I give an exposition and critical discussion of Sellars’s Myth of the Given, and especially of its epistemic side. In later writings Sellars takes a pragmatist turn in his epistemology. This is explored and compared with his earlier critique of givenist mythology. In response to Michael Williams, it is argued that these issues are importantly independent of philosophy of language or mind, and that my own take on them does not commit me to any absurd radical foundationalism on language or mind. My own take is in line with Descartes’ two-level epistemology of cognitio and scientia, a bifurcation that protects him from vicious circularity, and is adaptable for an epistemology naturalized, whether in the way of Quine, or Moore, or Davidson.

1. Sensa and propositional experience. 2. An option between propositions and properties (as objects or contents of sensory experience). 3. The property option and adverbialism. 4. Sensa as images, images as intentionalia. 5. Do we refer directly to sensa? 6. Focusing and the supervenience of images and our reference to them: a question raised. 7. Internal and external properties of images and characters. Strict vistas introduced. 8. A correction on strict vistas. 9. Focusing and experience: the question answered. 10. Conclusion.

Stephen Grimm finds me inclined to bifurcate epistemic assessment into higher and lower orders while showing awareness of this only in recent writings. Two untoward consequences allegedly follow: (a) my rejection of Virtue Reliabilism, and (b) my knowledge-based account of the value attaching to our knowledge on the higher level. By contrast, Grimm considers Virtue Reliabilism a perfectly adequate account of knowledge, while the higher epistemic state he believes to be, rather, understanding, which he takes to be quite distinct from knowledge. Once knowledge and understanding are seen to be distinct, finally, this will help us to avoid the two untoward consequences. I am grateful for these interesting points, and would like to respond briefly in what follows.

Jaegwon Kim is one of the most pre-eminent and most influential contributors to the philosophy of mind and metaphysics. This collection of essays presents the core of his work on supervenience and mind with two sets of postscripts especially written for the book. The essays focus on such issues as the nature of causation and events, what dependency relations other than causal relations connect facts and events, the analysis of supervenience, and the mind-body problem. A central problem in the philosophy of mind is the problem of explaining how the mind can causally influence bodily processes. Professor Kim explores this problem in detail, criticises the nonreductionist solution of it, and offers a modified reductionist solution of his own. Both professional philosophers and their graduate students will find this an invaluable collection.

Ever since Plato, philosophers have faced one central question: what is the scope and nature of human knowledge? In this volume the distinguished philosopher Ernest Sosa collects essays on this subject written over a period of twenty-five years. All the major topics of contemporary epistemology are covered: the nature of propositional knowledge; externalism versus internalism; foundationalism versus coherentism; and the problem of the criterion. 'Sosa is one of the most prominent and most important epistemologists on the current American scene.' William P. Alston, Syracuse University.

According to nomological accounts of causation causal connections among events or states must be mediated by contingent laws of nature. Three types of causal connection are cited and discussed in opposition to such nomological accounts: (a) material causation (as when a zygote is generated by the union of an ovum and a sperm); (b) consequentialist causation (as when an apple is chromatically colored as a result of being red); (c) inclusive causation (as when a board is on a stump in consequence of its having been placed there by a carpenter). These are all source-consequence relations or result-yielding relations and they are all cases of necessitation, each with its own distinguishing features.
