Are people silly for not having coherent, non-contradictory beliefs, or is it silly to expect intelligent people to have global, universal, coherent beliefs about messy reality?

The Cyc Project turned common sense into predicate logic... ...and found it necessary to create lots and lots of "microtheories" (locally consistent, mutually inconsistent) because anything vaguely large acquired contradictions.

looks like douglas lenat was at xerox parc in the early 80s - lucy suchman and other EM people were around then, I wonder if it influenced him?

The stories often talk about a naval simulation game with well defined rules as an early inspiration for "simply" coding the rules for "everything". I always just assumed the microtheory thing was a pragmatic hack born of necessity? :-Phttps://twitter.com/lexfridman/status/1199450924579733504 …

2:17Lex Fridman @lexfridmanHere's Richard Feynman, in 1985, describing Douglas Lenat's heuristic-based system and its winning solutions. Reminds me of reinforcement learning efforts of today. Given objectives & constraints, algorithms may lead to unexpected consequences.

At Veoh, I worked with a guy who used to work for the Cyc project. He had stories about the difficulty of getting predicates like "in" to work sanely. Like: Is paint on the inner walls of a room "in" the room? Is previous layer of paint also "in" the room? Same "in" for both?

Haha! Yeah. I was thinking specifically of you and your example, but this night is the first time I've ever had the two examples (that both hinge on "in") in my head at the same time I think :-P
