From LSD at Esalen

 An excerpt from How To Change Your Mind by Michael Pollan, Kindle edition, page 54 of 465.

Descriptions of such experiences always sound a little thin, at least when compared with the emotional impact people are trying to convey; for a life-transforming event, the words can seem paltry. When I mentioned this to [William] Richards, he smiled. “You have to imagine a caveman transported into the middle of Manhattan. He sees buses, cell phones, skyscrapers, airplanes. Then zap him back to his cave. What does he say about the experience? ‘It was big, it was impressive, it was loud.’ He doesn’t have the vocabulary for ‘skyscraper,’ ‘elevator,’ ‘cell phone.’ Maybe he has an intuitive sense there was some sort of significance or order to the scene. But there are words we need that don’t yet exist. We’ve got five crayons when we need fifty thousand different shades.”
