Friedman's early work was on the nature of scientific explanation and the philosophy of physics. His first book,
Foundations of Space-Time Theories, was published by
Princeton University Press in 1983 won the
Matchette Prize (now known as the Book Prize) from the
American Philosophical Association, to recognize work by a younger scholar. It also won the
Lakatos Award from the
London School of Economics to recognize outstanding work in philosophy of science.
Kant and the Exact Sciences was described in
Philosophical Review as "a very important book," "required reading for researchers on the relation between the exact sciences and Kant's philosophy."
UC Berkeley German philosophy professor
Hans Sluga described Friedman's 2000 book
A Parting of the Ways: Carnap, Cassirer, and Heidegger, a book that detailed the philosophies of
Carnap,
Cassirer, and
Heidegger, as "eye-opening" and "ambitious". The book shed new light on the split between
analytic philosophy and
Continental philosophy. In his book
Dynamics of Reason, Friedman "provides the fullest account to date not only of [his] neo-Kantian, historicized, dynamical conception of relativized
a priori principles of mathematics and physics, but also of the pivotal role that [he] sees philosophy as playing in making scientific revolutions rational." In 2015, he was awarded the
Fernando Gil International Prize for the Philosophy of Science for his book ''Kant's Construction of Nature''. Friedman was an
honorary professor at the
University of Western Ontario. == Personal life and death ==
