Ludwig von Mises
Praxeology; economic calculation argument; regression theorem; systematic Austrian economics.
Short History
An Austrian and later American economist who rebuilt economics around human action and carried the Austrian tradition through war, exile, and postwar academia.
Praxeology
Mises named praxeology as the general science of purposeful human action and showed why monetary calculation requires real market prices for capital goods.
Why this matters to Praxeos
Praxeos takes its method, its calculation problem, and much of its monetary architecture from Mises’s action-first system.
Key works

- Socialism
- The Theory of Money and Credit
- Economic Calculation in the Socialist Commonwealth
Ludwig von Mises is the architect of twentieth-century Austrian economics. He developed the systematic treatment of the tradition, fixed its methodological foundations, and produced — in 1920 — one of the most important predictions in the history of the social sciences.
That prediction was the economic calculation argument. In Die Wirtschaftsrechnung im sozialistischen Gemeinwesen (1920), Mises showed that a socialist economy cannot compute the rational allocation of the means of production. Without markets for capital goods, there are no prices for capital goods; without prices, there is no common unit of valuation by which to compare one production plan to another; without that unit, planning is not optimisation but arbitrary preference. The twentieth century's greatest economic experiment — the socialist calculation debate, and then the collapse of the Soviet Union — confirmed Mises in detail.
Mises's second contribution is praxeology: the axiomatic method he elaborated in Nationalökonomie (1940) and, in its definitive form, Human Action (1949). Starting from the axiom that man acts — a proposition a priori true because its denial is itself an action — Mises derives the whole of catallactics. This is not mathematical economics, and it makes no claim to empirical predictive power in the sense of physics; it is, rather, a scientific treatment of the necessary logical structure of any economy whatsoever.
His third contribution is the regression theorem of money (The Theory of Money and Credit, 1912), which solves the chicken-and-egg puzzle of money's value by tracing any medium of exchange back, via regress, to an earlier period in which the commodity was valued for non-monetary reasons.

In Praxeos
Mises is the project's anchor. calculation-problem renders his 1920 argument directly. halving-garden rests on his regression theorem. The planned action-axiom and abct-extended modules treat further facets.
