The diagram below is complex because because praxeology and its contents are incorrectly categorized by Mises. And Rothbard made it worse by exacerbating the initial errors.
1) Philosophy Proper – the entire discipline – is required to describe the logic of human action. Philosophy, if articulated in operational language (the language of science) is the science of human action.
2) The missing logic within philosophy, is that of human COOPERATION. And that is the category addressed by praxeology and praxeological reasoning.
3) The different disciplines within praxeology are simply various means of calculating various relations. Just as law, math, engineering, are different means of calculation specific relations that are, without such systems of logic, beyond our rational capacity.
4) From this perspective, we can represent all praxeological action in a simple, expanding hierarchy.
Mises tried. Rothbard tried. But they only grasped pieces of the puzzle. They were too influenced by the battle against the state, and so they framed the problem of human action and cooperation incorrectly.
