This paper focuses on the relation of genealogy and critique in Nietzsche’s late philosophy. It is argued that the late Nietzsche distinguishes between genealogy and critique. The genealogy of morality is a descriptive endeavour that shows the origin of values in processes of life. The critique of morality assesses the value of values from the perspective of life. It is argued that the concept of life is at the core of Nietzsche’s critical project and thus his fundamental standard. The paper also examines the role of the genealogical method in Nietzsche’s critical project. It is shown that the genealogy of values prepares their critique. Moreover, Nietzsche regards the alleged epistemic success of his genealogies as an indirect confirmation of the superiority of his evaluative position, i. e. of his affirmation of life.
