Louis Menand, Professor of English at the Graduate Center of the City University of New York, is an experienced writer, offering us felicitous prose that moves along at a pleasant clip. In spite of its catchy title, The Metaphysical Club is not about metaphysics and not about clubs; it is about contemporary conceptions of truth and the relationship of the observer to the observed. These topics were addressed by a group of very loosely associated thinkers after the Civil War in the United States. Their ideas were brought to later fruition in the well-known work of John Dewey, Oliver Wendell Holmes, Jr., William James, and Charles Peirce. These men, along with others, belonged to an informal discussion group that met for a few months in Cambridge, Mass., in 1872 and called itself the "Metaphysical Club" out of irony; these thinkers were actually engaged in the demolishing of Hegelian metaphysics and replacing it with various precursors of what came to be known as American pragmatism.
