# praxeology >[!Ref] Lexicon >a deductive science that examines the implications of the axiom that human beings act. > >------------ > (from the Greek, Praxis, action, habit or practice; logia, doctrine, theory or science). The science or general theory of (conscious or purposeful) human action. [Mises](https://www.freemarketcenter.com/lexicon/index.html#Ludwig%20von%20Mises)defines action as "the manifestation of a man's will. Accordingly, he considers the use of the adjectives "conscious or purposeful" to be redundant. Praxeology is a manifestation of the human mind and deals with the actions open to men for the attainment of their chosen ends. Praxeology starts from the a priori category of action and then develops the full implications of such action. Praxeology aims at knowledge valid for all instances in which the conditions exactly correspond to those implied in its assumptions and inferences. Its statements and propositions are not derived from experience, but are antecedent to any comprehension of historical facts. > [[Epistemological Problems of Economics - Mises (EP)]] (Praxeology translated as "sociology"), viii, 68-124; [[Human Action - Mises (HA)]] 1-3,30-36,47,51,57,64-71,174,646,648,651; [[Ultimate Foundation of Economic Science (UF)]] 14, 41-45, 64-65, 70-72. # Notes # References [Action Axiom](obsidian://open?vault=Substack&file=Published%20Content%2FAction%20Axiom) [[Praxeology - The Method of Economics (David Gordon)]]
