March 1977
Dick reads an essay Stanislaw Lem wrote about him and understands he has never been able to see causality the way everyone else does.
He reads the screenplay for Hitchcock’s North by Northwest and by equating his life to a script realizes 3-74 ridded him of his paranoia. He correctly summarizes this makes him look psychotic. He says he became schizophrenic, which cured him, and he admits his fear that the FBI was after him was a delusion.
He was a “paranoiac schiz” from 71 to 3-74 and had a full schizophrenic breakdown for a year after 3-74. After this a “toxin” secreted in his brain destroyed his persecutory complex. It appears now that depictions of paranoid worlds (like North by Northwest) are repellant to him.
Using the Greek concepts of idios kosmos and koinos kosmos Dick wonders if the schizophrenic world is the sane world and the normal world is the crazy one. Maybe during schizophrenia the brain is trying to achieve parity between the two hemispheres by releasing the toxin. Because of the right brain’s dominance though schizophrenia is a failed evolutionary leap.
His inability to understand causality (linear right-brained thinking) has allowed him to perceive how Zebra is communicating. One of his most important discoveries is that causality actually moves backwards.
