I am committed to the idea of living in a land where human rights are sacred, but the empiricist in me would like to be able to demonstrate with data, derived by the scientific method, that this is the best way to organize human societies. From the discussion here it seems Objectivists differ on whether Austrian economics is congruent with Objectivism, though.
Data cannot tell you what is best unless you define an objective. For instance, if empirical data suggested that you may be able to maximize GDP with slavery, that does not mean that it is the best outcome. (Respectfully) You also need to check a premises that seems to be implied by you statement: who organizes human society/should human society be organized? (maybe I am just reading into it too much)
Be careful not to confuse positive economic theory with normative economic philosophy, although they seem to inevitably cross paths. Positive economics, like any of the other sciences, should be judged by how well a theory describes some system within the universe (i.e.: the Fisher Equation, E. A. Phillips Curve, Efficient Markets Hypothesis, etc…). Normative economic ideas are an entirely different ball game; they are about the “should” and “aught,” whereas the positive ideas are about the “is” and “will.”
It is tempting to dismiss the valid positive economic thoughts of those with whom you have normative disagreements, but your relationship with reality will suffer. For instance, the fact that Paul Krugman might not respect my property rights does not reveal anything about the validity of his theories on the Japanese Credit Crunch of the 1990’s.
Similarly, the Austrian School’s use of Praxeology to describe/predict the economic consequences of human actions, macro & micro-level, does not, in and of its self, speak to the appropriateness or moral consequences of the actions of those humans.
Aside:
GreedyCapitalist, you typically have very insightful posts, but your dismissal of Econometrics was petty. Also, why do you think that Hayek was a “welfare statist?”
