Nietzsche made a pathological use of his best ideas, anchoring them in his own fluctuating bodily and mental conditions. Thus Nietzsche's belief that questions to truth and morality are at base questions of power and fitness resonates dynamically and intellectually with his alternating lucidity and delirium.

Enlightenment ideals of a society rooted in liberationist reason and morality were trampled in the wake of the savagery of the Second World War. That era's union of cold technology and ancient hatreds gave rise to a dark, alternative reason—an ethic that was value-free and indifferent with regard to virtue and vice, freedom, and slavery. In a world where "the unthinkable" had become reality, it is small wonder that theorists would turn to the writings of a man whose eighteenth-century imagination preceded twentieth-century history in its unbridled exploration of viciousness, perversion, and monstrosity: the Marquis de Sade. Klossowski was one of the first philosophers in postwar Europe to ask whether Sade's reason, although aberrant and perverted to evil passions, could be taken seriously. Klossowski's seminal work inspired virtually all subsequent study of Sadean thought, including that of de Beauvoir, Deleuze, Derrida, Bataille, Blanchot, Paulhan, and Lacan.

Shocking, brilliant, and eccentric, the French author, translator, and artist Pierre Klossowski (1905–2001) exerted a profound effect on French intellectual culture throughout the twentieth century. The older brother of the painter Balthus, secretary to the novelist André Gide, friend to Georges Bataille and Maurice Blanchot, and heralded as one of the most important voices in the French “return to Nietzsche” by Michel Foucault and Gilles Deleuze, Klossowski pursued his singular vision of mortal embodiment through a variety of scholarly manifestations. In Such a Deathly Desire (Un si funeste désir), Klossowski’s original interpretation of Nietzsche’s eternal return is developed around the enigmatic figure of the “demon,” then deepened with provocative readings of Gide’s correspondence; Barbey d’Aurevilly’s novel A Married Priest; and the intertwining of language and death in the work of Bataille, Blanchot, and Brice Parain. The book concludes with the powerful essay “Nietzsche, Polytheism, and Parody,” in which Klossowski articulates the consequences of the eternal return and the meaning of Nietzsche’s genealogy of the fabulation of the world. Intersecting with and confounding a range of disciplines—including psychoanalysis, literary criticism, gender studies, and philosophy—Klossowski’s critical writings on language, literature, and the aesthetics of embodiment remain powerful and original contributions to contemporary concerns in the theoretical humanities. --
