I entered this reading expecting wild and wacky, but I got much more than I bargained for. This book is absolutely ludicrous, out of touch with reality, and what's worse - appropriates neuroscience terminology and scientific aesthetics in a way that is misleading and damaging. It didn't take 12 pages before the Learys claimed that autism is caused by motherly neglect in the first several days of life, and that autism may be cured by administering LSD to the child and having the mother hug them for the 8 hour duration of a trip. I trust I don't have to explain just how messed up that is.

The whole thesis of the book is insane on the face of it - that human cognition is made up of just 7 "circuits" that build on each other. This was obviously false even to the psychology of the 1970s. It reads like the ravings of a stoned philosophy undergraduate who has heard in passing about Freud and just recently watched a TED talk on the brain. Similarly, the book contains a staggering density of incorrect and confused claims. Later chapters claim that right handed people exclusively use the left hemisphere and that their right is completely unusued. The right hemisphere is then seen as the unconscious mind, which can be accessed via cannabis. This is fairly bog standard when it comes to new age claims about the brain, but the scientific trappings that it attempts to cloak itself in are gross.

This book is a wild journey that needs to be read to be believed, and it culminates in something I never could have expected going in. Leary alleges that "The D.N.A. code" (his words) has been implanted by an interstellar being of some kind, and that the purpose of this "code" is to produce sufficiently advanced nervous systems with the goal of decoding DNA. "Wait", you might say, "doesn't each cell regularly transcribe DNA in order to synthesize proteins?" Yes, but Leary anticipates this interpretation and is quick to say that DNA's real purpose is to contain a complete history of the world, the future, and to reveal the "meaning of existence". This culminates in DNA's final message "Escape! The genetic entity wants off the planet". So according to the Learys, DNA is an alien virus that is desperately trying to escape from earth? It gets weirder though, because at the very end they allege that death is only a fear of the mind and that your consciousness will reside in everlasting bliss... *checks notes* inside your DNA.

In summary: this is wild, even for Leary. It's actually quite sad to me, knowing that he wrote this while in solitary confinement, and in some reports, in a cell next to Charles Manson in Folsom prison. It sort of tells a story of a man whose mind is deteriorating, which is clear when you see the breadth of his terminology. It would be quite an effort indeed to absorb so much technical language while displaying such basic ignorance of the facts of the field. No, I really think it must have been his mental decline. And while I personally believe in the therapeutic potential of psychedelics (especially MDMA), this book does his cause more harm than good by serving shovel-loads of bunk science. Avoid at all costs, unless you desire a good reason to pull your hair out. ( )
