Philip K. Dick Quote
My major preoccupation is the question, 'What is reality?' Many of my stories and novels deal with psychotic states or drug-induced states by which I can present the concept of a multiverse rather than a universe. Music and sociology are themes in my novels, also radical political trends; in particular I've written about fascism and my fear of it.
Statement of 1975 quoted in the Dictionary of Literary Biography (1981) vol. 8, part 1
