Abstract

One of the most important issues in contemporary epistemology is eliminating justification or replacing it by another factor in the structure of knowledge. The main problem in Virtue based epistemology that suggested by Ernes Sosa is the definition of knowledge structure. In this approach, the innovation of a new concept of the third factor in the structure of knowledge and replacing it with the justification is done in three stages. These stages are; criticizing and eliminating justification in its internalist meaning, removing externalist problems and innovating apt belief instead of justified belief. Intellectual virtue and epistemic perspective are two key concepts that provide essential situation for this replacement.
