"I want to write about people I love, and put them into a fictional world spun out of my own mind, not the world we actually have, because the world we actually have does not meet my standards. Okay, so I should revise my standards; I'm out of step. I should yield to reality. I have never yielded to reality. That's what SF is all about. If you wish to yield to reality, go read Philip Roth; read the New York literary establishment mainstream bestselling writers….This is why I love SF. I love to read it; I love to write it. The SF writer sees not just possibilities but wild possibilities. It's not just 'What if' - it's 'My God; what if' - in frenzy and hysteria. The Martians are always coming."
— Philip K. Dick
