Concept
Virtue epistemology is a current philosophical approach to epistemology that stresses the importance of intellectual and specifically epistemic virtues. Virtue epistemology evaluates knowledge according to the properties of the persons who hold beliefs in addition to or instead of the properties of the propositions and beliefs. Some advocates of virtue epistemology also adhere to theories of virtue ethics, while others see only loose analogy between virtue in ethics and virtue in epistemology. Intellectual virtue has been a subject of philosophy since the work of Aristotle, but virtue epistemology is a development in the modern analytic tradition. It is characterized by efforts to solve problems of special concern to modern epistemology, such as justification and reliabilism, by focusing on the knower as agent in a manner similar to how virtue ethics focuses on moral agents rather than moral acts. The area has a parallel in the theory of Unity of knowledge and action proposed by Chinese philosopher Wang Yangming Virtue epistemology was partly inspired by a recent renewal of interest in virtue concepts among moral philosophers, and partly as a response to the intractability of the competing analyses of knowledge that arose in response to Edmund Gettier. Ernest Sosa introduced intellectual virtue into contemporary epistemological discussion in a 1980 paper called "The Raft and the Pyramid". Sosa argued that an appeal to intellectual virtue could resolve the conflict between foundationalists and coherentists over the structure of epistemic justification. Foundationalism holds that beliefs are founded or based on other beliefs in a hierarchy, similar to the bricks in the structure of a pyramid. Coherentism, on the other hand, uses the metaphor of a raft in which all beliefs are not tied down by foundations but instead are interconnected due to the logical relationships between each belief. Sosa found a flaw in each of these schools of epistemology, in both cases having to do with the relationship between belief and perception.
