Alvin Goldman
Alvin Ira Goldman (born 1938) is an American professor of Philosophy at Rutgers University in New Jersey. He previously taught at the University of Michigan and at the University of Arizona. He earned his PhD from Princeton University and is married to the ethicist Holly Martin Smith. He has done influential work on a wide range of philosophical topics, but his principal areas of research are epistemology, philosophy of mind, and cognitive science.
Action theory
Goldman's early book, A Theory of Human Action (a revised version of his Ph.D. thesis), presents a systematic way of classifying and relating the many actions we perform at any time. Its influence was broad ref needed and can be found in, among other writings, John Rawls' book A Theory of Justice. Goldman's early work in action theory soon gave way to work in other branches of philosophy, most influentially epistemology.
Epistemology
Goldman's accounts of knowledge and justified belief, using notions like causation and reliability instead of normative concepts like permissibility and obligation, contributed to a philosophical approach that came to be known in the 1970s as naturalized epistemology. (Unlike W.V.O. Quine's version of naturalized epistemology, however, Goldman's retains a traditional focus on questions of justification.) Goldman's view emerged initially as part of the efforts in the 1960s to find a "fourth" condition in response to the Gettier challenge to the account of knowledge as "justified true belief." In his 1967 paper, "A Causal Theory of Knowing", Goldman proposed that knowledge amounts to true belief appropriately caused by the fact that makes it true. Later, he claimed knowledge amounts to true belief that is produced by a reliable process.
