"In The Longing for Total Revolution: Philosophic Sources of Discontent from Rousseau to Marx and Nietzsche (1986), the eminent intellectual historian and political theorist Bernard Yack offered a sweeping reinterpretation of modern thought. Yack argued that Rousseau prompted a line of philosophy that continued through Kant, Hegel, Marx and Nietzsche, which viewed the essential spirit of modernity as dehumanizing, and therefore implied, in a matter that became increasingly clear over time, that a total revolution against modernity is necessary. In this volume, seven political theorists and historians, including Yack himself, reconsider the book's substantive and methodological innovations, its limitations, and its current relevance. Contributors to the volume discuss, inter alia, left Kantianism in historical context, the theological origins of the longing for total revolution, the question of whether the tradition identified by Yack is connected to twentieth-century totalitarianism, and the unique form of critical genealogy pioneered by Yack's book. The volume concludes with Yack's response to the other contributors' chapters.".
