This chapter formulates a rational uniqueness principle holding that those who are epistemic peers on a proposition, in that they know that they share all rational considerations concerning the truth of the proposition, cannot be justified in having different attitudes toward it. It then argues against the principle, primarily on the grounds that such peers may rationally regard themselves as differing in their basis for rational belief, or their evidence, on the topic. The rationality of their differing perspectives can justify (...) having different attitudes toward the disputed proposition. (shrink)

This is an introduction to metaphysics for students and non-philosophers. (Philosophers: it's supposed to be the kind of book you can give to your friends and family, when they ask what you do for a living.) Contents: personal identity, fatalism, time, God, why not nothing?, free will, constitution, universals, necessity and possibility, what is metaphysics? (There is a second edition, which adds chapters on meta-metaphysics and the metaphysics of ethics.).

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)

Evidentialism holds that the justified attitudes are determined entirely by the person's evidence. This book is a collection of essays, mostly jointly authored, that support and apply evidentialism.

E j lemmon, B a o williams, Bas van fraassen, And ruth marcus have argued on behalf of the existence of moral dilemmas, I.E., Cases where an agent is subject to conflicting absolute moral obligations. The paper criticizes this support and contends that no moral dilemma is possible.

Guided by the work of William Alston, Jonathan Adler and Michael Levin propose a solution to the generality problem for reliabilism. In some respects their proposal improves on those we have discussed. We argue that the problem remains unsolved.

Experts take sides in standing scholarly disagreements. They rely on the epistemic reasons favorable to their side to justify their position. It is argued here that no position actually has an overall balance of undefeated reasons in its favor. Candidates for such reasons include the objective strength of the rational support for one side, the special force of details in the case for one side, and a summary impression of truth. All such factors fail to justify any position.

This is a wide-ranging defense of a distinctive version of hedonistic act utilitarianism. It is plainly written, forthright, and stimulating. Also, it is replete with disputable assertions and arguments. I shall pursue one issue here, after sketching the project of each substantial chapter.

In “Why the generality problem is everybody’s problem,” Michael Bishop argues that every theory of justification needs a solution to the generality problem. He contends that a solution is needed in order for any theory to be used in giving an acceptable account of the justificatory status of beliefs in certain examples. In response, first I will describe the generality problem that is specific to process reliabilism and two other sorts of problems that are essentially the same. Then I will (...) argue that the examples that Bishop presents pose no such problem for some theories. I will illustrate the exempt theories by describing how an evidentialist view can account for the justification in the examples without having any similar problem. It will be clear that other views about justification are likewise unaffected by anything like the generality problem. (shrink)

The paper argues against Timothy Williamson's anti-luminosity argument. It also offers an argument against luminosity from the possibility of defeat of introspective justification.

Tim defines a "luminous" condition as one that we are always in a position to know that we are in, whenever we are in it. To explain the idea of being in a position to know, Tim tells us that we are in a position to know a proposition when it states a fact that is open to our view, unhidden, and with no obstacle to our knowing it. He also tells us that if we are in a position to (...) know a proposition, and we do what we are in a position to do toward knowing whether or not it is true, then we know it to be true. So a luminous condition obtains only if it is all set to be known to obtain by the one in the condition. (shrink)

Some propositions are obvious in their own right. We can `just see' that they are true. So there is some such epistemic phenomenon as seeing the truth of a proposition. This paper investigates the nature of this phenomenon. The aptness of the visual metaphor is explained. Accounts of the phenomenon requiring qualia by which the truth is apprehended are disputed. A limited theory is developed and applied.

The leading approaches to the nature of epistemic justification are the sides taken in two controversies: coherentism versus foundationalism, and externalism versus internalism. The former dispute has time-tested durability; the latter threatens to become equally persistent. Nevertheless, it will be argued here that these controversies have satisfactory resolutions. It will be argued that each of the four approaches is fundamentally right. Each has a plausible core that combines consistently with the others. This paper offers a prolegomenon. Its goals are to (...) clear away apparent obstacles to a reconciliation among the approaches and to outline the resulting inclusive view. (shrink)

The essay seeks the best combination of internal and external factors in the evidential support that we can have for a proposition. After identifying the combination, the essay criticizes views according to which our evidence supports propositions in virtue of the propositions explaining the evidence to us.

O evidencialismo é, primordialmente, uma tese sobre a justificação epistêmica e, secundariamente, uma tese sobre o conhecimento. Sustenta que a justificação epistêmica é superveniente da evidência. As versões do evidencialismo diferem quanto ao que conta como evidência, quanto ao que seja possuir algo como evidência e quanto ao que um dado corpo de evidência apóia. A tese secundária é a de que o apoio evidencial é necessário ao conhecimento. O evidencialismo ajuda a formular as questões epistemológicas de uma forma que (...) é ótima para que se perceba o núcleo dos problemas. Oferece soluções, sem mascarar as dificuldades. Nós fornecemos ilustração disso através da consideração dos problemas da justificação a priori e do ceticismo. O evidencialismo também oferece a base para que se compreenda uma grande variedade de fatos e conceitos epistemológicos. Nós fornecemos ilustração disso, mostrando que o evidencialismo pode explicar como a justificação pode ser anulada, como as atitudes distintas da crença podem ser objeto de avaliação e como a própria prática da filosofia é epistemicamente valiosa. PALAVRAS-CHAVE – Evidencialismo. Evidência. Justificação. Conhecimento. A priori. Ceticismo. ABSTRACT Evidentialism is primarily a thesis about epistemic justification and secondarily a thesis about knowledge. It holds that epistemic justification supervenes on evidence. Versions of evidentialism differ about what counts as evidence, what it is to have something as evidence, and what a particular body of evidence supports. The secondary thesis is that evidential support is necessary for knowledge. Evidentialism helps to frame epistemological issues in a way that is optimal for seeing the heart of the problems. It offers solutions without disguising the difficulties. We illustrate this by considering the problems of a priori justification and skepticism. Evidentialism also provides the basis for understanding a variety of epistemological facts and concepts. We illustrate this by showing that evidentialism can explain how justification can be defeated, how attitudes other than belief can be the object of evaluation, and how the practice of philosophy itself is epistemically valuable. KEY WORDS – Evidentialism. Evidence. Justification. Knowledge. A priori. Skepticism. (shrink)
