Peter K. Machamer

Machamer's work has been influential in developing an account of scientific explanation understood as the search for and filling in of mechanisms. His co-authored 2000 article (with Lindley Darden and Carl Craver) “Thinking about Mechanisms”, published in Philosophy of Science, has been cited over 3,000 times. His current work explores further consequences of this view in "Activities and Causation: The Metaphysics and Epistemology of Mechanisms," International Studies in the Philosophy of Science 187.1 (2004): 27–39, and in work in progress "Explaining Mechanisms" and "Models as Models of Mechanisms."

Machamer earned his BA from Columbia University in 1964, his BA (1966) and MA (1971) from Trinity College, Cambridge University, and his PhD in philosophy from the University of Chicago in 1972. His dissertation, Points about Observation in Science, was supervised by Manley Thompson and Dudley Shapere. Machamer taught in the Department of Philosophy at Ohio State University from 1969 to 1976, receiving tenure, and then moved to the Department of History & Philosophy of Science at the University of Pittsburgh as associate professor in 1976, becoming professor in 1978. At the University of Pittsburgh, Machamer has served as chair (1978–1993) of History & Philosophy of Science, associate director of the Center for the Philosophy of Science (1999–present), and as a member of the Center for Neural Basis of Cognition (CNBC). He has also been affiliated with the Cultural Studies Program at the University of Pittsburgh since its inception. He has been a Fulbright fellow at the University of Athens and the National Technical University of Athens (1996) and visiting professor at Universita' degli Studi di Udine (1994), the National Technical University of Athens (1998), Boğaziçi University (1998), and the University of Konstanz (2007). He has also received grants from the NEH, the NSF, the Heinz Foundation, the Mellon Foundation, and the U.S. Department of Education.

Peter K. Machamer (born October 20, 1942) is an American philosopher and historian of science. Machamer was Professor of History and Philosophy of Science at the University of Pittsburgh. His work has been influential in philosophy of science in developing an account of mechanistic explanation which rejects standard deductive models of explanation, such as the deductive-nomological model by understanding scientific practice as the search for mechanisms. His research has also focused on 17th-century history of philosophy and science, on Galileo Galilei and René Descartes in particular, and on values and science. He was also a wine columnist for the Pittsburgh Post-Gazette for fifteen years, and he has reflected on wine and beer in philosophical writing. Machamer is also the "Philosopher in Residence" for the Pittsburgh dance company Attack Theater.
