Mises, Popper and Rothbard were half-right.

Popper was saved because libertarians didn’t use him as a vehicle for heaping undue praise, or pseudoscientific justificationism. Rothabardians damaged Mises so much that he is almost impossible to recover except by grouping him with Poincare, Brouwer and Bridgman as the people who failed to construct existential testing: operationalism.

Popper makes it half way to operationalism by correctly identifying scientific criticism but not operationalism (scientific operationalism). Then getting stuck in falsificationism.

Mises tries with praxeology to construct economic operationalism. Gets stuck in praxeology trying to state that something is true or not versus whether something is false or not.

The Legal profession struggles with strict construction and textualism (legal operationalism) – and I am not so sure why that movement failed like the other disciplines.

No one in the social sciences or philosophy creates moral or political operationalism – possibly because it would have to come from law or economics.

So this is the great philosophical failure of the 20th century. Why?

Attempts to abandon action. These are means of complex free association, not means of truth finding.
