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 The collection includes two previously unpublished essays and new afterwords to five of the reprinted essays; it will be the definitive resource on evidentialism for all epistemologists.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)

In this companion volume to Warrant: The Current Debate, Plantinga develops an original approach to the question of epistemic warrant; that is what turns true belief into knowledge. He argues that what is crucial to warrant is the proper functioning of one's cognitive faculties in the right kind of cognitive environment.

Consider the skeptic about the external world. Let’s straightaway concede to such a skeptic that perception gives us no conclusive or certain knowledge about our surroundings. Our perceptual justification for beliefs about our surroundings is always defeasible—there are always possible improvements in our epistemic state which would no longer support those beliefs. Let’s also concede to the skeptic that it’s metaphysically possible for us to have all the experiences we’re now having while all those experiences are false. Some philosophers dispute (...) this, but I do not. The skeptic I want to consider goes beyond these familiar points to the much more radical conclusion that our perceptual experiences can’t give us any knowledge or even justification for believing that our surroundings are one way rather than another.

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.

Virtually all philosophers agree that for a belief to be epistemically justified, it must satisfy certain conditions. Perhaps it must be supported by evidence. Or perhaps it must be reliably formed. Or perhaps there are some other "good-making" features it must have. But does a belief's justification also require some sort of awareness of its good-making features? The answer to this question has been hotly contested in contemporary epistemology, creating a deep divide among its practitioners. Internalists, who tend to focus (...) on scientific or theoretical beliefs as the ideal, insist that such awareness is required for justification. Externalists, who think children's ordinary beliefs in obvious facts are paradigm cases of justified belief, say it isn't required. Michael Bergmann's book offers a decisive refutation of internalism and a sustained defense of externalism. (shrink)

For many years now, much of BonJour’s work has focused on ways of developing a dilemma he finds in the work of Wilfred Sellars. In his earlier work, BonJour argued against internalist foundationalism using this Sellarsian dilemma. But he has since switched his allegiance and now wants to offer a solution to this dilemma on behalf of internalist foundationalism. He believes that if his solution fails, internalist foundationalism is in serious trouble. I agree with that conditional and my aim in (...) sections 1-3 will be to argue that his solution does fail. In the final section, I will briefly defend externalism against one of BonJour’s objections to it. (shrink)

Internalism about epistemic justification (henceforth, ‘internalism’) says that a belief B is epistemically justified for S only if S is aware of some good-making feature of B, some feature that makes for B’s having positive epistemic status: e.g., evidence for B. Externalists with respect to epistemic justification (‘externalists’) deny this awareness requirement. Michael Bergmann has recently put this dilemma against internalism: awareness admits of a strong and a weak construal; given the strong construal, internalism is subject to debilitating regress troubles; (...) given the weak construal, internalism is unmotivated; either way, internalism is in serious trouble. I argue for two claims in this article. First, Bergmann’s dilemma argument is unmotivated: he’s given no good reason for accepting one of its crucial premises. And second, Bergmann’s dilemma argument is unsound: the crucial premise in question is false. (shrink)
