The book gives a uniquely comprehensive philosophical analysis of Nietzsche's thinking. It shows how this thinking has its unifying focus on values: both the past and prevailing values that his psychologies and genealogies explain and the new values that he himself creates and defends. It maps, in detail, the argumentative structure of his thinking as it bears on this central topic. It argues that his ultimate ambition is to show how we can incorporate the truth about values into our own valuing-and that he is therefore more deeply committed to truth than often supposed. The book's chapters examine twelve key concepts, each at the heart of a network of problems and ideas.
