This is actually... a) very insightful, and b) something I don&#x27;t recall ever encountering before. Thanks a lot for the reference!<p>(Increasingly, I&#x27;m starting to feel that a lot of things I figure out for myself - often while writing HN comments - is something that&#x27;s been widely known for thousands of years. I guess I need to sit down and read some of those classic works.)
