A Virtue Epistemology presents a new approach to some of the oldest and most gripping problems of philosophy, those of knowledge and scepticism. Ernest Sosa argues for two levels of knowledge, the animal and the reflective, each viewed as a distinctive human accomplishment. By adopting a kind of virtue epistemology in line with the tradition found in Aristotle, Aquinas, Reid, and especially Descartes, he presents an account of knowledge which can be used to shed light on different varieties of scepticism, the nature and status of intuitions, and epistemic normativity.

This study aims primarily at an account of sensory experience and perception uncommitted to objectual sense data or sense impressions. In the end it does make room for sense impressions, but only as entities somehow abstracted from phenomenological attention to sense experience. The "phenomenological standpoint" is attained by imagining "that a transparent screen has been placed at right angles about three feet from your eyes between you and all the objects before you," and by imagining further that the projection of the objects on such a screen has been cleverly painted on it so as to present an appearance just like that presented by the objects then actually before you. "It is to this possible picture that your attention must now be directed in order for you to be said to be attending to your sense experience itself".

A main epistemic problematic, found already in Aristotle’s Posterior Analytics, presents a threefold choice on how a belief may be justified: either through infinitely regressive reasoning, or through circular reasoning, or through reasoning resting ultimately on some foundation. Aristotle himself apparently takes the foundationalist option when he argues that rational intuition is a foundational source of scientific knowledge. The five modes of Agrippa, which pertain to knowledge generally, again pose the same problematic, the “Pyrrhonian” problematic. And here Galen and the Stoics also opt for foundations. Sections I and II below explore that foundationalist option. Section III draws some lessons. And Section IV uses these to interpret Descartes. I argue that Descartes shows us the way beyond the Pyrrhonian problematic, although his way is not that traditionally attributed to him. On these basic issues of epistemology, Descartes is no Cartesian.

In what way is knowledge better than merely true belief? That is a problem posed in Plato’s Meno. A belief that falls short of knowledge seems thereby inferior. It is better to know than to get it wrong, of course, and also better than to get it right by luck rather than competence. But how can that be so, if a true belief will provide the same benefits? In order to get to Larissa you do not need to know the way. A true belief will get you there just as well. Is it really always better to know the answer to a question than to get it right by luck? In part i we ponder: Is knowledge always better at least in epistemic respects? The affirmative answer is subject to doubts deriving from a conception of belief as sufficient confidence, but is defensible against such doubts. In our search for the special value of knowledge, we then explore in part ii the relation between knowledge and proper action. Part iii goes on to consider how the value of knowledge intuition acquires further interest through its equivalence with the view of knowledge as a norm of assertion. Finally, part iv steps back to examine what we might mean in saying that to know is always, necessarily better than to get it right by luck while really in ignorance. In order to defend our value-of-knowledge intuition we need first to understand it more clearly. Part iv offers an explanation.

Thoroughly updated, the second edition of this highly successful textbook continues to represent the most comprehensive and authoritative collection of canonical readings in metaphysics. In addition to updated material from the first edition, it presents entirely new sections on ontology and the metaphysics of material objects. One of the most comprehensive and authoritative metaphysics anthologies available - now updated and expanded Offers the most important contemporary works on the central issues of metaphysics Includes new sections on ontology and the metaphysics of material objects, as well as readings on the topics of fictionalism, fundamentality, tropes, vague identity, temporary intrinsics, stage theory, and composition Surpasses other anthologies in its combination of contributions from leading metaphysicians and a younger generation of "rising-stars"

The received definition of knowledge (as true, evident belief) has recently been questioned by Edmund Gettier with an example whose principle is as follows. A proposition, p, is both evident to and accepted by someone S, who sees that its truth entails (would entail) (that either p is true or q is true). This last is thereby made evident to him, and he accepts it, but it happens to be true only because q is true, since p is in fact false. Hence, inasmuch as he has no evidence for the proposition q, S can hardly be said to know (that either p is true or q is true). Here then is a formula for true, evident beliefs that are not cases of knowledge. I discuss the possibility of adding a fourth condition to this triad.

According to Moore, his argument meets three conditions for being a proof: first, the premiss is different from the conclusion; second, he knows the premiss to be the case; and, third, the conclusion follows deductively.2 Further conditions may be required, but he evidently thinks his proof would satisfy these as well. As Moore is well aware, many philosophers will feel he has not given “...any satisfactory proof of the point in question."3 Some, he believes, will want the premiss itself proved. But he has..
