Born in Cuba, Ernest Sosa immigrated to the USA as a teenager. After his BA from the University of Miami, and his PhD from the University of Pittsburgh, he has taught at Brown University and then at Rutgers, each for decades. During that time he has had numerous dissertation students who have attained distinction. He was a President of the American Philosophical Association (Eastern) and was elected to the American Academy of Arts and Sciences. In 1980 he inaugurated the virtue theoretic approach in epistemology, which he has developed through a half dozen books, many published articles, and replies in many author/critic sessions and books. He has given several distinguished lectures, including the Locke and the Carus Lectures, and has received several prizes. The APA has established a prize lectureship and a fellowship in his honor for excellence in epistemology.
