I will explore the life and work of Philip K. Dick, best known for writing Science Fiction, by closely examining a number of his novels, as well as a selection of his non-fictional, philosophical, theological and literary writings, coupled with information obtained from biographies and interviews with the man himself. The main themes permeating his life and work which I will explore are the nature of reality, the psyche and humanity, especially in relation to contemporary capitalist society. Of particular interest will be his exploration of the concepts of sanity, considering his views on schizophrenia and paranoia, and his treatment of ideas about selfhood, identity and subjectivity. I will explore these areas in terms of the philosophy of Gilles Deleuze, both alone and in collaboration with Felix Guattari. I will pay particular attention to the concepts of schizoanalysis, rhizomatics, territorialization, lines of flight, nomadology, becomings, machines and difference. My aim, rather than to reach a definitive conclusion, is simply to explore the vast and complex works of both men, using each to shed light on the other, and to pose questions, rather than propose answers, which will have a profound effect on the way we view the world.
