The chapter “Nietzsche’s ethics” introduces Nietzsche’s ethical standpoint through four interrelatedsections. The first, “Three faces of Nietzsche’s ethics,” explores the diverse types of values that underpin his ethical framework. The second, “The concept of life in Nietzsche,” examines the strand of naturalism emphasized in recent interpretations and proposes a reading of Nietzsche’s genealogy consistent with a broader naturalistic perspective. It further argues that genealogy should yield a causal explanation that integrates both everyday notions of causality and an organicist understanding of part–whole relations. The third section, “The normativity of Nietzsche’s ethics,” analyzes the formal features of Nietzsche’s normative-ethical position, clarifying what “ethics” can mean within his philosophy. It also considers the normative concepts inherent in his work and the distinctions between normative and non-normative, as well as ethical and non-ethical, domains. The fourth section, “The affirmation of life as the ideal of Nietzsche’s ethics,” identifies the core features that define Nietzsche’s ethical ideal. It emphasizes the normative conditions through which life affirmation emerges as a counterpoint to the ascetic ideal that negates life.
