Comprehensive and packed, Alvin Plantinga's two-volume treatise defies sum- mary. The first volume, Warrant: Current Views, is a meticulous critical survey of epistemology today. Many current approaches are presented and exhaustively discussed, and a negative verdict is passed on each in turn. This prepares the way for volume two, Warrant and Proper Function, where a positive view is advanced and developed in satisfying detail. The cumulative result is most impressive, and should command attention for years to come. Here I cannot possibly do justice to the scope and richness of Plantinga's accomplishment. Given the limitations imposed by the occasion, I will discuss only what seem the most important and original proposals, and will compare them with some relevant alternatives

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"

In “Tracking, Competence, and Knowledge,” Ernest Sosa notes that in attempting to account for the conditions for knowledge, externalists have proposed that the justification condition be replaced or supplemented by the requirement that a certain modal relation be obtained between a fact and a subject's belief concerning that fact. While assessing attempts to identify such a relation, he focuses on an account labeled “Cartesian‐tracking”, which accounts for the relation in the form of two conditionals. If a person S believes a proposition P → P P → S believes P. Sosa suggests that be abandoned as a requirement, and that, equipped with his modifications, can offer promising results in connection with skepticism. He argues that modified coupled with the requirement that S's belief be “virtuous” can illuminate the nature of propositional knowledge.

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.

The mind-body problem arises because of our status as double agents apparently en rapport both with the mental and with the physical. We think, desire, decide, plan, suffer passions, fall into moods, are subject to sensory experiences, ostensibly perceive, intend, reason, make believe, and so on. We also move, have a certain geographical position, a certain height and weight, and we are sometimes hit or cut or burned. In other words, human beings have both minds and bodies. What is the relation between these? Religion often tells us that we are really embodied souls released at death from our bodily prisons. Could this be right?

Truth centered epistemology puts truth at the center in more ways than one. For one thing, it makes truth a main cognitive goal of inquiry. For another, it explains other main epistemic concepts in terms of truth. Knowledge itself, for example, is explained as belief that meets certain other conditions, among them being true. And a belief is said to be rationally or epistemically justified or apt, which it must be in order to be knowledge, only if it derives from a truth-conducive faculty, an intellectual virtue. What defensible theories of truth are open to such truth-centered epistemology? That is our main question.

It is argued that knowledge is a form of action. It is a kind of successful attempt to attain the truth. The success must avoid a particular sort of “epistemic luck”. It must derive from competence rather than luck. Knowledge, then, is a judgment or belief that aims at truth and attains accuracy not by luck but through the agent’s cognitive adroitness, so that the attainment is apt. A higher grade of knowledge then requires that the agent attain aptly not only the accuracy (truth) but even the aptness of that first-order success. This more fully apt success is on a higher level of epistemic achievement, and in this respect is a special case of a general truth of performance normativity that applies across domains of human performance, whether in the arts, in sports, in the professions, and so on. An attempt in general reaches that higher level of achievement by being not only apt but fully apt.

This chapter has four parts. The first lays out Williamson's account of mental concepts and mental states, and his characterization of knowledge as the most general factive stative attitude. The second problematizes the account of mental states and the characterization of knowledge, and offers an alternative account of when a state is purely mental; according to this account, knowledge really is mental only by courtesy of the contained belief (an internalist intuition opposed to the externalism featured in the book). The third part reflects on possible sources and support for such a conception of the purely mental. The fourth and last part takes up the KK principle, Williamson's reductio of it, and the consequences of that for the possibility of reflective knowledge.

Ernest Sosa extends his distinctive approach to epistemology, intertwining issues concerning the role of the will in judgment and belief with issues of epistemic evaluation. Questions about skepticism and the nature of knowledge are at the forefront. The answers defended are new in their explicit and sustained focus on judgment and epistemic agency. While noting that human knowledge trades on distinctive psychological capacities, Sosa also emphasizes the role of the social in human knowledge. Basic animal knowledge is supplemented by a level of reflective knowledge focused on judgment, and a level of 'knowing full well' that is distinctive of the animal that is rational.
