Nietzsche is known as a severe critic of German Idealism, but what exactly is the relation between his thought and theirs? And how does Nietzsche's stance differ from the critique of idealism in Kierkegaard and Schopenhauer?The papers from leading international specialists in German Idealism, Schopenhauer, Kierkegaard and Nietzsche address these questions. The aim of the volume is to introduce novel ways of addressing the complex relations between Nietzsche and his immediate philosophical predecessors: Schopenhauer, Kierkegaard, Hegel, Schelling, Fichte and Kant. The focus is on the profound interconnections and affinities between their ways of thinking. Each paper considers one particular aspect of Nietzsche's philosophy (such as his notion of "spirit", "law", "power", "will", his "physiology" or his critique of morality) in relation to the above-mentioned philosophers. This largely systematic approach reveals surprising affinities between Nietzsche and the German idealists, despite their patent differences and generates new perspectives from which to understand and reinterpret Nietzsche's thought.
