Congratulations! Something I had thought about before about wood as well. Wood, metal, substance depth can be very overlooked and it's sort of paradoxical. (1)

Why don't we just cut the crap and say it? And the conclusion that I came to, this is an earlier book, The Stuff of Thought (subtitle is Language is a Window into Human Nature), is that direct speech generates common knowledge, and that common knowledge is the basis of our social relationships. Two people--if they're friends, if they're lovers, if they're transactional partners, if they're in a dominance hierarchy--all of those are equilibria in coordination games, and they're matters of common knowledge. In the case of friends, it's we're equal, we would do anything for each other, we're there for each other, and that's kind of the common knowledge that makes friends friends. Clip on direct speech and common knowledge from an interview with Robert Contofalsky (Robert Contofalsky) of R-Academy. -- My new book, When Everyone Knows That Everyone Knows . . .: Common Knowledge and the Mysteries of Money, Power, and Everyday Life is available here:

I had the pleasure of being a guest on Science of Perception Box, a video podcast from Unlikely Collaborators. New episodes drop every Wednesday. Me: Eye contact can often generate common knowledge. We know, even from the ethological literature in animal communication, that eye contact is a very potent signal because you’re looking at the part of the person that’s looking at the part of you that’s looking at the part of them that’s looking at the part of you. And so eye contact can generate common knowledge. It often resolves ambiguities in, say, a car stopping and a pedestrian crossing. Establishing eye contact would be a way of generating that common knowledge. Christof Koch: Or two cars merging on a freeway, right? The other guy sort of briefly nods. Me: Exactly. And in fact, I was tickled to see a sign in the San Francisco airport parking lot, which I actually photographed and included in the book. It has a cartoon of a pedestrian and a driver, with a dashed line joining their eyes, and it says, “Make eye contact before crossing.” There it is. Yes. Dr. Heather Berlin
