Innovations are good. Better innovations are better. And, yes, Mises made an innovation, but the expository and explanatory power of the deductive and axiomatic method is LESS than the expository and explanatory power of the ratio-empirical method – not more.
Congratulating Mises on improving Kant, who was probably the single greatest contributor to philosophical obscurantism and the destruction of reason in human history, is hardly a compliment. Its an accusation of conspiracy. (See Rand on Kant. Kantian pseudoscience is part of the reason the libertarian project from the continent has failed.)
Hoppe’s argument is stated within the context of economic action. He is arguing that economics is purely deductive rather than like all other ‘sciences’ a mixture of:
(a) the limits of our biological ability to perceive in real time,
(b) a theory describing a general rule,
(c) the use of logic to test the internal consistence of the theory,
(d) and instrumental tests that replicate and falsify the theory
But he misunderstands (or intentionally mischaracterizes) the development of theories. There is no point in retesting them if they’ve been sufficiently tested and criteria for falsification defined. We can develop economic laws just like we can develop physical laws. But we cannot develop economic axioms because axioms are not required to be correspondent with reality, while theories are – and human action exists in reality.
Philosophy itself, when expressed operationally, as action (realism), rather than as analogy (platonism etc), or as experience (phenomenalism etc), results in a statement of the ratio-empirical method. The philosophy of action is science, not rationalism, precisely because only science requires demonstration of action. Reason does not. Reason is a continental attempt to conflate authority, morality and reason as a reaction to ratio-empircal science, and commercial morality which would upset the hierarchy as it has in the anglo countries.
It’s nonsense though. Economics, and human action, are empirical sciences that may, for the purposes of convenience be reduced to laws that are expressible in axiomatic terms. But axiomatic systems are not dependent upon external correspondence, and as such economics cannot under any circumstances be reduced to a logic. It is a science. It is the most challenging science because it lacks causal relations but it is a science born of observation, reducible to theories, we can use as laws, but these laws are not equivalent to axioms because axioms are not bounded by reality.
