In chapter 5 of Knowledge and its Limits, T. Williamson formulates an argument against the principle (KK) of epistemic transparency, or luminosity of knowledge, namely “that if one knows something, then one knows that one knows it”. Williamson’s argument proceeds by reductio: from the description of a situation of approximate knowledge, he shows that a contradiction can be derived on the basis of principle (KK) and additional epistemic principles that he claims are better grounded. One of them is a reflective (...) form of the margin for error principle defended by Williamson in his account of knowledge. We argue that Williamson’s reductio rests on the inappropriate identification of distinct forms of knowledge. More specifically, an important distinction between perceptual knowledge and non-perceptual knowledge is wanting in his statement and analysis of the puzzle. We present an alternative account of this puzzle, based on a modular conception of knowledge: the (KK) principle and the margin for error principle can coexist, provided their domain of application is referred to the right sort of knowledge.

... and Normative Epistemology The Distinction Between Metaepistemology and Normative Epistemology Although this terminology is relatively new, ...

Nozick analyzes fundamental issues, such as the identity of the self, knowledge and skepticism, free will, the foundations of ethics, and the meaning of life.

In Unnatural Doubts, Michael Williams constructs a masterly polemic against the very idea of epistemology, as traditionally conceived.

Sorensen here offers a unified solution to a large family of philosophical puzzles and paradoxes through a study of "blindspots": consistent propositions that cannot be rationally accepted by certain individuals even though they might by true.

This article surveys work in epistemology since the mid-1980s. It focuses on contextualism about knowledge attributions, modest forms of foundationalism, and the internalism/externalism debate and its connections to the ethics of belief.

In his recent Knowledge and its Limits, Timothy Williamson argues that no non-trivial mental state is such that being in that state suffices for one to be in a position to know that one is in it. In short, there are no “luminous” mental states. His argument depends on a “safety” requirement on knowledge, that one’s confident belief could not easily have been wrong if it is to count as knowledge. We argue that the safety requirement is ambiguous; on one (...) interpretation it is obviously true but useless to his argument, and on the other interpretation it is false. (shrink)

In section one the deontological (or responsibilist) conception of justification is discussed and explained. In section two, arguments are put forward in order to derive the most plausible version of perspectival internalism, or the position that epistemic justification is a function of factors internal to the believer's cognitive perspective. The two most common considerations put forward in favor of perspectival internalism are discussed. These are the responsibilist conception of justification, and the intuition that two believers with like beliefs and experiences (...) are equally justified in their like beliefs. In section three it is argued that perspectival internalism is false, and that in fact the position is not supported by a responsibilist conception of justification. Section four explicates two other forms of internalism, which are rejected for reasons similar to those presented against perspectival internalism. In section five, an internalist theory of justification is defended which is supported by a responsibilist conception of justification. Roughly stated, the position is that justified belief is belief which arises from the use of correct rules of reasoning. The idea of correctness is explicated, and the position is distinguished from others which are similar to it. (shrink)

Evidentialism is a view about the conditions under which a person is epistemically justified in having a particular doxastic attitude toward a proposition. Evidentialism holds that the justified attitudes are determined entirely by the person's evidence. This is the traditional view of justification. It is now widely opposed. The essays included in this volume develop and defend the tradition.Evidentialism has many assets. In addition to providing an intuitively plausible account of epistemic justification, it helps to resolve the problem of the (...) criterion, helps to disentangle epistemic and ethical evaluations, and illuminates the relationship between epistemic evaluations of beliefs and the evaluation of the methods used to form beliefs. These issues are all addressed in the essays presented here. External world skepticism poses the classic problem for an epistemological theory. The final essay in this volume argues that evidentialism is uniquely well qualified to make sense of skepticism and to respond to its challenge.Evidentialism is a version of epistemic internalism. Recent epistemology has included many attacks on internalism and has seen the development of numerous externalist theories. The essays included here respond to those attacks and raise objections to externalist theories, especially the principal rival, reliabilism. Internalism generally has been criticized for having unacceptable deontological implications, for failing to connect epistemic justification to truth, and for failing to provide an adequate account of what makes basic beliefs justified. Each of these charges is answered in these essays. The collection includes two previously unpublished essays and new afterwords to five of the reprinted essays; it will be the definitive resource on evidentialism for all epistemologists. (shrink)

This paper uses the knowledge account of assertion (KAA) in defense of epistemological contextualism. Part 1 explores the main problem afflicting contextualism, what I call the "Generality Objection." Part 2 presents and defends both KAA and a powerful new positive argument that it provides for contextualism. Part 3 uses KAA to answer the Generality Objection, and also casts other shadows over the prospects for anti-contextualism.

The dominant response to this problem of the criterion focuses on the alleged requirement that we need to know a belief source is reliable in order for us to acquire knowledge by that source. Let us call this requirement, “The KR principle”.

Since Socrates, and through Descartes to the present day, the problems of self-knowledge have been central to philosophy's understanding of itself. Today the idea of ''first-person authority''--the claim of a distinctive relation each person has toward his or her own mental life--has been challenged from a number of directions, to the point where many doubt the person bears any distinctive relation to his or her own mental life, let alone a privileged one. In Authority and Estrangement, Richard Moran argues for (...) a reconception of the first-person and its claims. Indeed, he writes, a more thorough repudiation of the idea of privileged inner observation leads to a deeper appreciation of the systematic differences between self-knowledge and the knowledge of others, differences that are both irreducible and constitutive of the very concept and life of the person.Masterfully blending philosophy of mind and moral psychology, Moran develops a view of self-knowledge that concentrates on the self as agent rather than spectator. He argues that while each person does speak for his own thought and feeling with a distinctive authority, that very authority is tied just as much to the disprivileging of the first-person, to its specific possibilities of alienation. Drawing on certain themes from Wittgenstein, Sartre, and others, the book explores the extent to which what we say about ourselves is a matter of discovery or of creation, the difficulties and limitations in being ''objective'' toward ourselves, and the conflicting demands of realism about oneself and responsibility for oneself. What emerges is a strikingly original and psychologically nuanced exploration of the contrasting ideals of relations to oneself and relations to others. (shrink)

J. David Velleman casts foreknowledge of one's own next move as psychologically active. As agents, we form prior intentions about what we will do next. Such prior intentions are licensed self-fulfilling beliefs or directive cognitions. These cognitions differ from ordinary predictions in their psychological relation to the evidence, in that they precede that crucial part of the evidence which consists in the fact that they have been formed. However, once formed, these cognitions are epistemologically unremarkable: they are directly justified by (...) evidence, which saliently includes the fact of their own existence. I argue that Velleman distorts both the epistemology and the etiology of self-knowing agency. Self-knowing agents typically know what they will do next non-evidentially, and yet their knowledge of their own next move is formed in response to their (perspective-relative) epistemic grounds. Velleman's account of self-knowing agency is doubly distortive because it ignores the role of the purely first-person point of view which typically characterizes such agency. In developing an alternative account of self-knowing agency, I argue that the kind of knowledge that we typically have of what we are about to do is like the kind of knowledge we have when we non-evidentially know what our own current, conscious propositional thoughts are. We can non-evidentially know what we think in virtue of having made up our minds what to think. Likewise, we can non-evidentially know what we are about to do in virtue of having settled on what to do next. (shrink)

Ernest Sosa has argued that if someone knows that p, then his belief that p is “safe”. and Timothy Williamson has agreed. In this paper I argue that safety, as defined by Sosa, is not a necessary condition on knowledge – that we can have unsafe knowledge. I present Sosa’s definition of safety and a counterexample to it as a necessary condition on knowledge. I also argue that Sosa’s most recent refinements to the notion of safety don’t help him to (...) avoid the counterexample. I consider three replies on behalf of the defender of safety, and find them all wanting. Finally, I offer a tentative diagnosis of my counterexample. (shrink)

_The Foundations of Knowing _ was first published in 1982. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions. This collection of essays on the foundations of empirical knowledge brings together ten of Roderick M. Chisholm's most important papers in epistemology, three of them published for the first time, the others significantly revised and expanded for this edition. The essays in Part I constitute a (...) thoroughgoing defense of foundationalism—the doctrine that our justification for believing always rests upon a self-evident basis. In Part II, Chisholm applies foundationalist principles to various areas within the theory of knowledge, and in part III he presents a history of twentieth-century American epistemology. "Roderick M. Chisholm's work has been most influential both in the development of epistemology and in the widespread application of his analytic method. I am sure this publication featuring the unification of his views will be of great value to those working on the central issues of philosophy." Hector-Neri Castañeda, Indiana University Roderick Chisholm is Andrew W. Mellon Professor of the Humanities in the department of philosophy at Brown University. Among his books are _Perceiving: A Philosophical Study, Theory of Knowledge, Person and Object_,and _The First Person _. (shrink)

It is argued that a subject's evidence consists of all and only the propositions that the subject knows.

Externalism about knowledge commits one to a modest form of contextualism: whether one knows depends (or may depend) on circumstances (context) of which one has no knowledge. Such modest contextualism requires the rejection of the KK Principle (If S knows that P, then S knows that S knows that P) - something most people would want to reject anyway - but it does not require (though it is compatible with) a rejection of closure. Radical contextualism, on the other hand, goes (...) a step farther and relativizes knowledge not just to the circumstances of the knower, but to the circumstances of the person attributing knowledge. I reject this more radical form of contextualism and suggest that it confuses (or that it can, at least, be avoided by carefully distinguishing) the relativity in what S is said to know from the relativity in whether S knows what S is said to know.
