"Actually, there’s a nice story from Ancient Egypt about the god Thoth, the god of wisdom, who is very proud of himself because he has invented writing. “Look at this gift,” he says to a mythical pharaoh of that time, “Look at the gift that I’m giving humanity, writing. This is a wonderful thing. It’ll enable you to preserve so much that you would otherwise lose.” And the pharaoh in this story replies to him, “No, you have not given us a wonderful gift. You have destroyed the art of memory. We will forget everything. Words will roam free around the world, not accompanied by any wise advice to set them into context.” And actually that’s a very interesting point. And we do know that cultures that still do have oral traditions are able to preserve information for very long periods of time."

"One thing I think is clear in any time, in any period of history, is human beings love stories. We love great stories. And one way to preserve information is to encode it, embed it in a great story. And so carefully done that actually, it doesn’t matter whether the storyteller knows that they’re passing on that information or not. The story itself is the vehicle. And as long as it’s repeated faithfully, the information contained within it will be passed on. And I do think this is part of the story of the preservation of knowledge."

"I think that shamanism is the origin of everything of value in humanity. I think it was the earliest form of science. When I spend time with shamans in the Amazon, I observe people who are constantly experimenting with plants in a very scientific way. They’re always trying a pinch of this and a pinch of that in different forms, for example, of the ayahuasca brew, to see if it enhances it or makes it different in any way. The invention of curare is a remarkable scientific feat, which is entirely down to shamans in the Amazon. They are the scientists of the hunter-forager state of society and they were the ancient leaders of human civilization."
