Adding to this because I feel a bit annoyed at how John C Lilly gets so badly represented sometimes. He wasn’t a nut job. He was a weird guy with a very unique personality. He had an intense passion for knowledge and scientific inquiry. He also had a massive ego. But he was a reasonably self reflective person. Read his books and watch interviews with him. He wasn’t just a hedonist who got addicted to K. He always had a very non typical experience of reality. He had hallucinations of angels as a child, partly due to a heavily religious upbringing. It’s totally understandable that he was primed for strange trips when he got into psychedelics. But he was able to function as a professional. He had multiple government funded research projects during his career, medical credentials, and owned electrical engineering patents. His characterisation as a kook is very similar to the crap that people say about Tim Leary, who had a successful academic career before being kicked out of Harvard and was actually a very rational person.
