La généalogie de la morale

On the Genealogy of Morality: A Polemic (German: Zur Genealogie der Moral: Eine Streitschrift) is an 1887 book by German philosopher Friedrich Nietzsche. It consists of a preface and three interrelated treatises ('Abhandlungen' in German) that expand and follow through on concepts Nietzsche sketched out in Beyond Good and Evil (1886). The three treatises trace episodes in the evolution of moral concepts with a view to confronting "moral prejudices", specifically those of Christianity and Judaism. Some Nietzsche scholars consider Genealogy to be a work of sustained brilliance and power as well as his masterpiece. Since its publication, it has influenced many authors and philosophers.
