I like Confucius and Schrodinger's cat thingie.

Although Plato seems to have the best understanding of government that I've read. Basicly Democracy ends when people figure out that they can use the government to their own ends.

Confucius had a pretty good ethical system -- basicly you have duties to everyone around you. You owe something to your older brother, and your older brother owed something to you. Seems to work pretty well. And it's been tried in China for 2000 some years. worked pretty well, I think.
