The Genealogy of Morals.

Friedrich Nietzsche called this book a polemic, and it reads like one: three sustained essays that take a hammer to the assumption that our moral values are self-evident or eternal. Instead he asks the disturbing question of where they came from, and whose interests they have served.

What it's about

In three connected essays, Nietzsche investigates the origins of moral concepts. He contrasts two ways of valuing rooted in different historical conditions, traces the emergence of guilt and bad conscience from the relationship of debtor and creditor, and turns finally to the meaning and power of ascetic ideals in religion, philosophy, and science.

Themes

The historical and psychological roots of morality, resentment, conscience, self-denial, and the will to truth run throughout. Nietzsche practises what he calls genealogy: not asking whether values are true, but how they came to feel like truths.

Why it still matters

Few books have done more to shape modern suspicion of inherited values, influencing psychology, philosophy, and social thought across the twentieth century and beyond. Its method of interrogating the origins of what we take for granted remains startlingly powerful.

Who it's for

Readers of philosophy ready for a challenging, provocative text, and anyone drawn to Nietzsche's assault on comfortable certainties. Best approached with attention and an open mind.
