Abstract: This book presents a full commentary on Nietzsche's On the Genealogy of Morality and combines close reading of key passages with an overview of Nietzsche's wider aims. It argues that Nietzsche's practice of genealogy pursues psychological and historical truths concerning the origins of modern moral values, but also emphasizes the significance of his rhetorical methods as an instrument of persuasion. Nietzsche's outlook is broadly one of naturalism, but he is critical of typical scientific and philosophical methods for their advocacy of impersonality and suppression of the affects. Nietzsche's principal opponents are Schopenhauer and Paul Rée, both of whom account for morality in terms of selflessness. Nietzsche believes that our allegiance to a post-Christian morality that centres around selflessness, compassion, guilt, and denial of the instincts is not primarily rational but affective: underlying feelings, often ambivalent and poorly grasped in conscious thought, explain our moral beliefs. The Genealogy is designed to detach the reader from his or her allegiance to morality and prepare for the possibility of new values. According to Nietzsche's ‘perspectivism’, this book argues that one can best understand a topic such as morality through allowing as many of one's feelings as possible to speak about it. And Nietzsche's further aim is to enable us to ‘feel differently’: to this end his provocation of the reader's affects both helps us grasp the affective origins of our attitudes and prepares the way for healthier values such as the affirmation of life and the self-satisfaction to be attained by ‘giving style to one's character’.
