These essays reveal another side of Horkheimer, focusing on his remarkable contributions to critical theory in the 1930s. Max Horkheimer is well known as the director of the Frankfurt Institute for Social Research and as a sometime collaborator with Theodor Adorno, especially on their classic Dialectic of Enlightenment. These essays reveal another side of Horkheimer, focusing on his remarkable contributions to critical theory in the 1930s. Included are Horkheimer's inaugural address as director of the Institute, in which he outlines the interdisciplinary research program that would dominate the initial phase of the Frankfurt School, his first full monograph, and a number of other pieces published in the 1930s. The essays, most of which have not appeared in English before, are surprisingly relevant to current post-philosophy debates, notably "On the Problem of Truth," with its focus on pragmatism, and "The Rationalism Debate in Current Philosophy," a sustained critique of the post-Cartesian philosophy of consciousness. Horkheimer's 1933 critique of Kantian ethics, "Materialism and Morality," is of particular interest given the current reaction to the neo-Kantian aspect of Habermas's work. There are also essays relevant to the current foundations debate within Continental philosophy, and the rationality/relativism question is sustained throughout the volume.

One of the central figures in modern thought, Max Horkheimer (1895?1973) was the director of the Institute of Social Research at the University of Frankfurt and guided the activities of the Frankfurt School from its origins in Germany through its exile in the United States during World War II. The Frankfurt School writers developed what came to be known as Critical Theory, and anyone familiar with poststructuralist theory in the humanities and social sciences will recognize its indebtedness to the Frankfurt School. ø These letters show how Horkheimer?s thought was influenced by and engaged with the historical events of the twentieth century, particularly the Holocaust and the Vietnam War. The letters trace the trajectory of his thought from an early optimism about the possibility of revolutionary change to a critique of orthodox Marxism as his faith in revolution was replaced by a commitment to the transformative power of education. ø These letters also convey the contours of Horkheimer?s personal relationships and illustrate the connection of Horkheimer and the Frankfurt School to the work and thought of some of the most important figures in the intellectual life of the nineteenth and twentieth centuries, including Karl Marx, Thomas Mann, Sigmund Freud, Theodor Adorno, and Herbert Marcuse.
