We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
He wrote treatises on chess, math, and other things too. Imagine what sort of website he could have had, had he only invented the intertunnels too. Everybody knows that Sippican invented the intertunnels.
Double entry sounds like tax cheating, but it is not. It is about credits and debits. (It does not refer to the private, personal books for cash receipts that many unscupulous Lefties use to dodge Uncle Sam and rip off their neighbors.)

Fra Pacioli figures prominently in Alfred Crosby's The Measure of Reality: Quantification and Western Society, 1250-1600. This is a fascinating read on how Western Europe remade itself in the centuries that followed the collapse of the Western Roman Empire and ultimately achieved global pre-eminence. I don't often finish a book and then start it over right away, but with this one, I did. Most highly recommended.
