b. 1961
John Greco is a contemporary American philosopher specializing in epistemology, particularly virtue epistemology and the nature of knowledge. He is best known for developing an agent reliabilist account of knowledge, arguing that knowledge requires true belief produced by the exercise of intellectual virtue. His work has significantly shaped debates around epistemic responsibility, testimony, and the value of knowledge.
