Brehon law had the same basic principles in it as the Founders espoused. Are you sure it wasn't based off of that? Makes more sense really. Instead of having an Inquisition deciding what the law was and how it applied, or a sovreign King deciding law, the old Celts had a seperate and educated adjudication class. Sounds a lot more like our modern legal system than some priest saying "God told me to tell you this".
What is it with you libertarians? You all think we should be ruled by "philosopher kings" who just "reason" up the law as they go along. Why do you want us to be ruled by elites?
Libertarians are like Marxists in that they think that only their philosophical school has the capacity to reason and they have all the answers. If only the people would see the wisdom of voting Libertarian, then America would be a utopia with no need of government at all. The only difference between this childish fantasy and Marxism are that they're different roads to achieve the same impossible goal.
