Analyses Deleuze's notion of transcendental and genetic Ideas as conditions of creative thought. From his early work in 'Nietzsche and Philosophy' to 'Difference and Repetition', Deleuze develops a unique notion of transcendental philosophy. It comprises a radical critique of the illusions of representation and a genetic model of thought.Engaging with questions of representation, Ideas and the transcendental, Daniela Voss offers a sophisticated treatment of the Kantian aspects of Deleuze's thought, taking account of Leibniz, Maimon, Lautman and Nietzsche along the way.
