"Genealogy of Morals" is a philosophical work by Friedrich Nietzsche, published in 1887. In this text, Nietzsche explores the origins and development of moral values, questioning the traditional notions of good and evil. He argues that moral concepts are not universal truths but rather products of historical and cultural contexts. The work is divided into three essays, each addressing different aspects of morality. Nietzsche contrasts master morality, which values strength and nobility, with slave morality, which arises from the resentment of the weak. Through this analysis, he aims to reveal the underlying power dynamics that shape moral beliefs.
