Perhaps this is an easier to digest approach: Jaak Panksepp studied rats: https://en.wikipedia.org/wiki/Jaak_Panksepp Why do rats laugh? Interview with Jaak Panksepp... https://www.youtube.com/watch?v=u4ICY6-7hJo He not only discovered that rats laugh and giggle (just in frequencies above what we humans can normally hear), he discovered that in repeated play-bouts, rats enjoy "rough and tumble" playing (just like human children, and dogs). Further, rather than stop after one round of playing and evidencing that larger rats dominate smaller rats, he studied specific pairs of rats over repeated play bouts (amongst other things). A larger rat will always show its physical prowess by dominating a smaller rat, in the first (and perhaps first few) play bouts, but these rats enjoy playing, and if a larger rat of the studied pair does not allow the smaller of the pair in a play bout to "win" at least 30% of the time, the smaller rat will not continue to play with the larger rat - it won't do that crouching type of invitation to play, that dogs and some humans also do when they want to play rough and tumble. So to get maximum play time (which these rats will hammer away on a button in order to obtain - they really do like playing rough and tumble with each other), larger rats must allow smaller rats to win at least 30% of the time, and, they generally do learn to do this. So the ethic here is not "winning a play bout" but how to "win the most across all play bouts, or, how to get more play time" which requires some level of treating your play partners (or "opponents") fairly. Thus, emergent ethics. Sam Harris and "scientific" "pure existentialists" who wish to base their ethics purely on facts (and not on religious hogwash or "air") would, I imagine, be lapping this up. Pretty cool stuff. And Jordan Peterson has been bringing an awareness of Jaak Panksepp and his rat play bout studies, and the consequent theory of an emergent basis for ethics, to an audience of millions - Peterson presents Panksepp's work in a compelling, comprehendable, (evidently) accessible, and enjoyable way. It is easy to appreciate and be grateful for this fact. So, how's that for a starter - tasty and accessible enough?
