The easiest are the technical ones, the things I was trained to do in law school: how to read a statute, how to apply the rules of evidence. I have a lot of help in the history of the law for that. The most difficult ones are defining the components of human liberty, because if you insist that the individual has a particular right, that means the legislature cannot infringe on that right. And, sometimes your own values and your own morals really would disapprove of the conduct that you’re ratifying, but you do so because there’s an area of morality. But, morality really should have an underpinning of rational choice, and each citizen must make a rational choice to determine what is good and what is evil, and those are hard.
