Ernest Sosa

For me the two-day workshop was an excellent experience. It was very good to be reminded of all those issues that I had grappled with so intensely in earlier years, and I very much appreciated the opportunity to think about them again and to try to put them in perspective with the stimulus of the critical teams’ focused attention. I am very pleased and grateful for the intense attention and challenge to my views, and for the excellent comments. I will do my best to respond with some helpful discussion.

Survey results are in the first instance utterances, which require interpretation. Moreover, when the results seem to involve disagreement in intuitive responses to a thought experiment, the results are most directly responsive to the scenario as envisaged by the particular subject, where the text of the example can give rise to relevantly different scenarios, depending on how the scenario is shaped by the subjects involved, under the guidance of the text. All of this opens up a defense of intuitions against results that ostensibly imply extensive intuitive disagreement based on cultural or socio-economic background. Critics of the armchair have replied to this defense in recent publications. This paper takes up some of those replies

Ever since Plato it has been thought that one knows only if one's belief hits the mark of truth and does so with adequate justification. The issues debated by Laurence BonJour and Ernest Sosa concern mostly the nature and conditions of such epistemic justification, and its place in our understanding of human knowledge. Presents central issues pertaining to internalism vs. externalism and foundationalism vs. virtue epistemology in the form of a philosophical debate. Introduces students to fundamental questions within epistemology while engaging in contemporary debates. Written by two of today’s foremost epistemologists. Includes an extensive bibliography.

Epistemology is too far-flung and diverse for a survey in a single essay. I have settled for a snapshot which, though perforce superficial and partial, might yet provide an overview. My perspective is determined by the books and articles prominent in the recent literature and in my own recent courses and seminars. Seeing that the boundaries of our field have shifted through the ages and are even now very ill-marked, I have chosen two central issues, each under vigorous and many-sided discussion in recent years and at present: (A) Scepticism, and (B) Theories of Justification; and in each case I shall focus on work either published or widely discussed within the last five years.

In this book, Ernest Sosa explains the nature of knowledge through an approach originated by him years ago, known as virtue epistemology. Here he provides the first comprehensive account of his views on epistemic normativity as a form of performance normativity on two levels. On a first level is found the normativity of the apt performance, whose success manifests the performer's competence. On a higher level is found the normativity of the meta-apt performance, which manifests not necessarily first-order skill or competence but rather the reflective good judgment required for proper risk assessment. Sosa develops this bi-level account in multiple ways, by applying it to issues much disputed in recent epistemology: epistemic agency, how knowledge is normatively related to action, the knowledge norm of assertion, and the Meno problem as to how knowledge exceeds merely true belief. A full chapter is devoted to how experience should be understood if it is to figure in the epistemic competence that must be manifest in the truth of any belief apt enough to constitute knowledge. Another takes up the epistemology of testimony from the performance-theoretic perspective. Two other chapters are dedicated to comparisons with ostensibly rival views, such as classical internalist foundationalism, a knowledge-first view, and attributor contextualism. The book concludes with a defense of the epistemic circularity inherent in meta-aptness and thereby in the full aptness of knowing full well

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

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".

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..

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.
