Since Law and Chaos align quite a lot with social values, I tend to just sort of wing it based on the surrounding setting. In a setting inspired by the Warring States era, a Confucian-inclined character would be lawful while a Daoist-inclined one would be chaotic. In one inspired by 18th century France, a chaotic character would be a revolutionary while a lawful one would be a monarchist. It tends to end up good enough for most purposes, but it's of course not very useful for finding more "objective" definitions of them. That's why I propose that each alignment contains internal contradictions.
