The Metaphysical Club: A Story of Ideas in America is a Pulitzer Prize-winning 2001 book by Louis Menand, an American writer and legal scholar. The Metaphysical Club recounts the lives and intellectual work of the handful of thinkers primarily responsible for the philosophical concept of pragmatism, a principal feature of American philosophical achievement: William James, Oliver Wendell Holmes, Jr., Charles Sanders Peirce, and John Dewey. Pragmatism proved to be very influential on modern thought.
