You probably never heard of Philip K. Dick, but he has change they way we look at he world many times...

Philip K. Dick was a man who saw the future, literally. He was a precog. He also believed that he had an alien that helped him look into the future. If it were not for Philip Dick movies like The Matrix, Inception and the Truman Show (to name a few) would never have been made.

This year saw the 30th anniversary of the death of one of the most influential writers of all time, the iconic Philip K. Dick. Although virtually unknown outside of science fiction circles, during his lifetime Dick’s intriguing philosophy on the nature of reality has become a staple of the modern Hollywood movie. Huge blockbusters such as Total Recall, Minority Report, The Adjustment Bureau, Blade Runner, A Scanner Darkly and Paycheck were loosely based directly on his novels or short stories, and movies such as The Eternal Sunshine of the Spotless Mind, Memento, The Matrix, The Truman Show and Inception all owe a huge debt to his vision.

Indeed the voice was quite precise when it stated:

“Your son has an undiagnosed right inguinal hernia. The hydrocele has burst, and it has descended into the scrotal sac. He requires immediate attention, or will soon die.”
Phil told various versions of this story, including one involving him listening to the Beatles and the lyrics of “Strawberry Fields” were changed to give the instruction.

Tessa, acting on her husband’s frantic instructions, took Christopher to the family doctor and it was, indeed, confirmed that Christopher had exactly the problem the “voice” had described and surgery was needed.
