Max Horkheimer (1895-1973), one of the founders of critical theory and a sometime colleague of Herbert Marcuse, Theodor Adorno, and Walter Benjamin, has become a subject of renewed attention and appreciation in Germany in the last decade. This collection of essays by German and American scholars will help familiarize English-speaking readers with the most important results of this recent work and, in conjunction with a companion volume of Horkheimer"s essays, Between Philosophy and Social Science, should provide a much fuller and deeper picture of his role in the history of modern social theory.
