Death is often characterised within naturalism as being ‘nothing to us’ and we are urged to think of ‘nothing less than of death’. In his lectures on Spinoza, Deleuze says ‘thinking of death is the most base thing’. Thinkers such as Lucretius, Nietzsche and Spinoza, have clear perspectives on the need to avoid thinking about death. They share in the belief that meditation on death only leads to fear and sadness. These affirmationists, that is, philosophers whose writings aim at affirming (...) life, therefore denounce death as unimportant to philosophy. Deleuze also presents a philosophy that seems affirmationist, in keeping with the tradition of those whose ideas he interprets and incorporates into his own philosophy. And yet, death - in the form of the death drive - is a key concept in Deleuze’s work Difference and Repetition. This thesis asks the question: Does Deleuze present a concept of death that affirms life? The concept of death is rarely explored in Deleuze studies, and yet it plays an important role in his philosophy. This thesis seeks to contribute to this research, by delineating and examining Deleuze’s concept of death in Difference and Repetition. The description of death provided by Deleuze is compared with the concepts of death in the works of two affirmationists, Lucretius and Spinoza. Hegel’s concept of death is then explored to determine whether Deleuze succeeds in avoiding the use of negation in death’s relation to the subject. The thesis then considers Deleuze’s interpretation of Nietzsche’s eternal return. The result of his use of the eternal return leads to discussions around kenosis, transpantheism and immanence. It is decided that the naturalist process of demystification is taken by Deleuze to require the demystification of identity, giving primacy to immanence as a singular life. (shrink)
