From Arnold Kling, who is blogging again.
What I am suggesting is that libertarians, rather than defining ourselves in terms of what we believe is right, could instead define ourselves in terms of how one should arrive at beliefs about what is right. Our goal should be to rely as much as possible on logic and as little as possible on heuristic biases. If using these methods leads to the conclusions that are traditionally libertarian, fine. If not, then we should change our conclusions, not our methods.
