Reality

Reality is that which, when you stop believing in it, doesn’t go away.

- Philip K Dick (1928-82)

Philip K Dick was a prolific science-fiction writer whose works have been made into eleven motion pictures, with three more on the way.  Among the best known films based on his writings are Blade Runner (from his story Do Androids Dream of Electric Sheep?), Total Recall, Minority Report, The Adjustment Bureau and A Scanner Darkly.  Among his other books is The Man in the High Castle, an alternate history in which Germany and Japan occupy America after winning World War II.

Dick himself often had a tenuous hold on reality.
