So we and our elaborately evolving computers may meet each other halfway. Someday a human being, named perhaps Fred White, may shoot a robot named Pete Something-or-other, which has come out of a General Electric factory, and to his surprise see it weep and bleed. And the dying robot may shoot back and, to its surprise, see a wisp of gray smoke arise from the electric pump that it supposed was Mr. White's beating heart. It would be rather a great moment of truth for both of them.
Philip K. DickThe psychotic does not merely think he sees four blue bivalves with floppy wings wandering up the wall; he does see them. An hallucination is not, strictly speaking, manufactured in the brain; it is received by the brain, like any 'real' sense datum, and the patient act in response to this to-him-very-real perception of reality in as logical a way as we do to our sense data. In any way to suppose he only 'thinks he sees it' is to misunderstand totally the experience of psychosis.
Philip K. DickMy 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.
