As someone who bas taken a bunch of LSD, psilocybin mushrooms, and DMT, as well as listened to a bunch of Terrence McKenna...the stoned ape theory is total horse shit. It’s a slap in the face to evolutionary biology and just a completely nonsensical “theory”
Not the stoned ape theory. I don't believe that at all. But the overall theory of geometric shapes and the relationship with the interworkings of our brain.
