Knowledge, context, and social standards

This paper defends the view that standards, which are typically social in nature, play a role in determining whether a subject has knowledge. While the argument focuses on standards that pertain to reasoning, I also consider whether there are similar standards for memory and perception.Ultimately, I argue that the standards are context sensitive and, as such, we must view attributions of knowledge as indexical. I exploit similarities between this view and a version of the relevant alternatives reply to skepticism in order to defend this reply against the objection that it is ad hoc.

Two Kinds of Skeptical Argument

This paper compares two kinds of epistemic principles-an underdetermination principle and a deductive closure principle. It argues that each principle provides the basis for an independently motivated skeptical argument. It examines the logical relations between the premises of the two kinds of skeptical argument and concludes that the deductive closure argument cannot be refuted without refuting the underdetermination argument. The underdetermination argument, however, can be refuted without refuting the deductive closure argument. In this respect, the deductive closure argument is the stronger of the two.

Skepticism and Everyday Knowledge Attributions

One of the more puzzling aspects of the issues concerning skepticism is the stark contrast between our everyday assertions concerning what we know and the conclusions of skeptical arguments. Skeptical arguments, which appear to be quite formidable, conclude that we know very little, whereas in everyday life we attribute a considerable amount of knowledge to ourselves.
