Ernest Sosa has made and continues to make major contributions to a wide variety of topics in epistemology. In this paper I discuss some of his core ideas about the nature of knowledge and scepticism. I start with a discussion of the safety account of knowledge – a view he has championed and further developed over the years. I continue with some questions concerning the role of the concept of an epistemic virtue for our understanding of knowledge. Safety and virtue (...) hang very closely together for Sosa. All this easily leads to some thoughts on epistemic scepticism and on Sosa's stance on this. (shrink)

A belief is reflectively lucky if it is a matter of luck that the belief is true, given what a subject is aware of on reflection alone. Various epistemologists have argued that any adequate theory of knowledge should eliminate reflective luck, but doing so has proven difficult. This article distinguishes between two kinds of reflective luck arguments in the literature: local arguments and global arguments. It argues that local arguments are best interpreted as demanding, not that one be reflectively aware (...) of the reliability of the sources of one’s beliefs, but that one’s beliefs be attributable to one as one’s own. The article then argues that global arguments make illegitimate demands, because they require that we be ultimately answerable for our beliefs. In the end, the article argues that epistemologists should shift their focus away from reflective luck and toward the conditions under which beliefs are attributable to cognitive agents. (shrink)

What are the qualities of an excellent thinker? A growing new field, virtue epistemology, answers this question. Section I distinguishes virtue epistemology from belief-based epistemology. Section II explains the two primary accounts of intellectual virtue: virtue-reliabilism and virtue-responsibilism. Virtue-reliabilists claim that the virtues are stable reliable faculties, like vision. Virtue-responsibilists claim that they are acquired character traits, like open-mindedness. Section III evaluates progress and problems with respect to three key projects: explaining low-grade knowledge, high-grade knowledge, and the individual intellectual virtues.

This paper argues that John Greco’s agent reliabilism fails in its attempt to meet the double requirement of accounting for the internalist intuition that knowledge requires sensitivity to the reliability of one’s evidence and evading the charge of psychological implausibility.
