Supporting Rafe's project, I suggest that some of Popper's work adds credibility to the action axiom and integrates economics more closely with the natural sciences: http://radicalliberal.blogspot.com/2013/03/ludwig-von-mises-action-axiom-and.html

It seems that libertarians expect this incredible fidelity when their (mine, too) heroes enter the policy domain. The fact that Mises was also grateful to fascist Italy for initially staving off the Anschluss was simply a value judgment that he liked not being enslaved or murdered by Nazis, not an endorsement of fascism. When attempting to apply principles to the political domain we are bound to fail, as will the physician advising the witch doctor. With politics it is always a question of who will be coerced, how much and in what fashion, not what principles foster social cooperation.
