It's no good selling everything the government owns and then saying that maybe you were wrong. Just as it's possible to speak a language without ever studying grammar or play billiards without studying physics it's possible to live well without having an explicit theory about how to do it. We may never completely understand how our social environment works. As with the natural environment we need to trust it and maintain it while accepting that nobody is in control. TOO BAD Rationalists look at the values and beliefs flourishing in a community and feel driven to root out the inconsistencies and enforce neatness and order.
Economic rationalists try to make everything fit with efficiency.
Libertarians are fanatical about freedom and egalitarians about equality. For conservatives the fact that our values often conflict is just part of life. X-Cons believe that fanatical pursuit of one value above all others is destructive, not virtuous. The Jurassic Conservatives are an endangered species. There have few new converts.
