“The journalist researches a story. The novelist imagines it.
What’s funny is, you’d be amazed at the amount of time a novelist has to spend with people in order to create this single lonely voice. This seemingly isolated world.
It’s hard to call any of my novels “fiction.””

In Pursuit of Valis: Selections from the Exegesis (1991)
Context: I am a fictionalizing philosopher, not a novelist; my novel and story-writing ability is employed as a means to formulate my perception. The core of my writing is not art but truth. Thus what I tell is the truth, yet I can do nothing to alleviate it, either by deed or explanation. Yet this seems somehow to help a certain kind of sensitive troubled person, for whom I speak. I think I understand the common ingredient in those whom my writing helps: they cannot or will not blunt their own intimations about the irrational, mysterious nature of reality, and, for them, my corpus of writing is one long ratiocination regarding this inexplicable reality, an investigation and presentation, analysis and response and personal history. My audience will always be limited to those people.
