'''''Human Action: A Treatise on Economics''''' is a work by the [[Austrian School|Austrian]] economist and philosopher [[Ludwig von Mises]]. Widely considered Mises' ''[[Masterpiece|magnum opus]]'',<ref>{{cite book |title=Champions of a Free Society: Ideas of Capitalism's Philosophers and Economists |last=Younkins |first=Edward W. |location=Lanham, Maryland |publisher=Lexington Books |year=2007 |isbn=978-0739126479 |oclc=228676591 |page=184}}</ref> it presents the case for [[laissez-faire]] [[capitalism]] based on [[praxeology]], his method to understand the structure of human decision-making. Mises rejected [[positivism]] within economics, and defended an ''[[A priori and a posteriori|a priori]]'' foundation for [[praxeology]], as well as [[methodological individualism]] and laws of self-evident certainty.<ref>{{Cite web |last=kanopiadmin |date=2011-05-31 |title=True Knowledge from A Priori Theory |url=https://mises.org/library/true-knowledge-priori-theory |access-date=2023-02-24 |website=Mises Institute |language=en}}</ref> Mises argues that the free-market economy not only outdistances any government-planned system, but ultimately serves as the foundation of civilization itself.<ref name=":0">{{Cite web |last=Tho |date=2019-09-03 |title=Ludwig von Mises's Human Action: Marking 70 Years of Continuing Relevance |url=https://mises.org/wire/ludwig-von-misess-human-action-marking-70-years-continuing-relevance |access-date=2023-02-24 |website=Mises Institute |language=en}}</ref>

Mises argues that market-generated money prices are essential to determine the most highly valued uses for resources to satisfy consumer demands. He attempts to demonstrate the inconsistencies of piecemeal political intervention in the market economy and the pernicious effects of political control and manipulation of the monetary system. In Mises's view, government interventions that distort market prices always result in misdirections of resources, including labor, and malinvestments of capital, leading to inflationary upswings followed by inevitable economic downturns. Mises believed that the market economy was the only system that provided freedom and personal choice to all members of society while generating the means for coordinating the actions of billions of people in the most economically rational manner, and that monetary manipulation by central banks was one of the most disruptive distortions to the process of economic calculation.<ref name=":0" />

==Summary==
{{One source section|text=The section is summarized entirely from the book itself, i.e., a single primary source.|date=February 2023}}

In his '''Introduction''', Mises argues that economics emerged as a science when a regularity in the sequence and interdependence of market phenomena was discovered. He notes the challenges faced by economics as a new science, particularly in being accepted as a legitimate branch of knowledge, and discusses various schools of thought that rejected the achievements of economic thought. Mises refutes common criticisms against economics, stating that the ideas of classical economists have improved the general standard of living by promoting liberal policies and technological improvement. He also argues that economic problems cannot be isolated as they are just a segment of a general science of human action.<ref>{{Cite book |last=Von Mises |first=Ludwig |url=https://www.worldcat.org/oclc/826659916 |title=Human action : a treatise on economics |date=2006 |publisher=Liberty Fund |others=Bettina Bien Greaves |isbn=978-1-61487-837-7 |location=Indianapolis |oclc=826659916}}</ref>

=== Part One: Human Action ===
'''Chapter 1''', "Acting Man", explains the concept of '''[[Action (philosophy)|human action]]''', which is defined as"purposeful behavior" and distinguished from reflexive behavior in that an observer imputes a goal to the actor.<ref name=":1">{{Cite web |title=Purposeful Action and Animal Reaction |url=https://mises.org/library/human-action-0/html/pp/613 |access-date=2023-02-24 |website=Mises Institute |language=en |archive-date=February 24, 2023 |archive-url=https://web.archive.org/web/20230224161141/https://mises.org/library/human-action-0/html/pp/613 |url-status=dead }}</ref> '''Praxeology''' is the science of action as such, which studies the results deduced from the fact that people have goals and adopt means to achieve them.<ref name=":1" /> For an action to occur, the actor must be in a state of unease, imagine a more satisfactory state, and believe that purposeful behavior can reduce the uneasiness.<ref name=":2">{{Cite web |title=The Prerequisites of Human Action |url=https://mises.org/library/human-action-0/html/pp/614 |access-date=2023-02-24 |website=Mises Institute |language=en |archive-date=February 24, 2023 |archive-url=https://web.archive.org/web/20230224161141/https://mises.org/library/human-action-0/html/pp/614 |url-status=dead }}</ref> The text addresses the concept of happiness and instinct, where '''happiness''' is defined entirely by the subjective goals of the individual actor, and humans can suppress their biological urges.<ref name=":2" /> The study of human action begins with the ultimate given of human action itself, and all studies of human actions must rely on [[methodological dualism]].<ref>{{Cite web |title=Human Action as an Ultimate Given |url=https://mises.org/library/human-action-0/html/pp/615 |access-date=2023-02-24 |website=Mises Institute |language=en |archive-date=May 31, 2023 |archive-url=https://web.archive.org/web/20230531035212/https://mises.org/library/human-action-0/html/pp/615 |url-status=dead }}</ref> Praxeology is subjective, as it takes actors' subjective ends as they exist in the minds of each person, but by refraining from passing judgment on these ends, it remains objective.<ref>{{Cite web |title=Rationality and Irrationality; Subjectivism and Objectivity of Praxeological Research |url=https://mises.org/library/human-action-0/html/pp/616 |access-date=2023-02-24 |website=Mises Institute |language=en |archive-date=June 1, 2023 |archive-url=https://web.archive.org/web/20230601161911/https://mises.org/library/human-action-0/html/pp/616 |url-status=dead }}</ref> Causality is necessary for action, and the [[Uncertainty principle|Heisenberg uncertainty principle]] does not alter this.<ref>{{Cite web |title=Causality as a Requirement of Action |url=https://mises.org/library/human-action-0/html/pp/617 |access-date=2023-02-24 |website=Mises Institute |language=en |archive-date=June 6, 2023 |archive-url=https://web.archive.org/web/20230606102901/https://mises.org/library/human-action-0/html/pp/617 |url-status=dead }}</ref> Finally, the text introduces the concept of the alter ego, where all events must fall in the realm of [[teleology]] or causality.<ref>{{Cite web |title=The Alter Ego |url=https://mises.org/library/human-action-0/html/pp/618 |access-date=2023-02-24 |website=Mises Institute |language=en |archive-date=May 30, 2023 |archive-url=https://web.archive.org/web/20230530232320/https://mises.org/library/human-action-0/html/pp/618 |url-status=dead }}</ref>

'''Chapter 38''', "The Place of Economics in Learning", explains, firstly, that the establishment of an institute for business-cycle research is not sufficient to find cures for business cycles.<ref name=":104">{{Cite web |title=The Study of Economics |url=https://mises.org/library/human-action-0/html/pp/927 |access-date=2023-02-24 |website=Mises Institute |language=en |archive-date=February 24, 2023 |archive-url=https://web.archive.org/web/20230224161153/https://mises.org/library/human-action-0/html/pp/927 |url-status=dead }}</ref> Clear thinking and sound [[Economics|economic theory]] are needed.<ref name=":104" /> Secondly, the rise of [[Economist|economics as a profession]] is due to [[Interventionism (politics)|interventionism]], and many [[Economist|professional economists]] only [[Privilege (law)|advance the interests of a small group]].<ref>{{Cite web |title=Economics as a Profession |url=https://mises.org/library/human-action-0/html/pp/928 |access-date=2023-02-24 |website=Mises Institute |language=en |archive-date=February 24, 2023 |archive-url=https://web.archive.org/web/20230224161434/https://mises.org/library/human-action-0/html/pp/928 |url-status=dead }}</ref> Thirdly, economists can only [[Prediction|predict]] the general timing of [[Business cycle|boom-bust cycles]], and successful entrepreneurs need to have better [[Forecasting|forecasts]] than their [[Rivalry|rivals]].<ref>{{Cite web |title=Forecasting as a Profession |url=https://mises.org/library/human-action-0/html/pp/929 |access-date=2023-02-24 |website=Mises Institute |language=en |archive-date=February 24, 2023 |archive-url=https://web.archive.org/web/20230224161218/https://mises.org/library/human-action-0/html/pp/929 |url-status=dead }}</ref> Fourthly, although economics is a unified whole, university professors engage in [[Division of labour|compartmentalized]] [[Analysis|analyses]], and the fallacies of [[Interventionism (politics)|interventionism]] preached by professors may lead some students to support [[socialism]].<ref>{{Cite web |title=Economics and the Universities |url=https://mises.org/library/human-action-0/html/pp/930 |access-date=2023-02-24 |website=Mises Institute |language=en |archive-date=February 24, 2023 |archive-url=https://web.archive.org/web/20230224161404/https://mises.org/library/human-action-0/html/pp/930 |url-status=dead }}</ref> Fifthly, the conflict between different [[Philosophy of history|interpretations of history]] and economics exists in [[school]]s, but most students are too [[Maturity (psychological)|immature]] to [[Choice|choose]] among them, and teachers cannot present them [[Neutrality (philosophy)|neutrally]].<ref>{{Cite web |title=General Education and Economics |url=https://mises.org/library/human-action-0/html/pp/931 |access-date=2023-02-24 |website=Mises Institute |language=en |archive-date=February 24, 2023 |archive-url=https://web.archive.org/web/20230224163219/https://mises.org/library/human-action-0/html/pp/931 |url-status=dead }}</ref> Lastly, modern [[government]]s [[Censorship|suppress freedom of economic thought]], but citizens have a [[duty]] to familiarize themselves with basic economic theory, as modern [[Political scandal|political controversies]] revolve around the [[Conflict (process)|conflict]] between socialism and the market economy.<ref>{{Cite web |title=Economics and the Citizen |url=https://mises.org/library/human-action-0/html/pp/932 |access-date=2023-02-24 |website=Mises Institute |language=en |archive-date=February 24, 2023 |archive-url=https://web.archive.org/web/20230224161242/https://mises.org/library/human-action-0/html/pp/932 |url-status=dead }}</ref><ref>{{Cite web |title=Economics and Freedom |url=https://mises.org/library/human-action-0/html/pp/933 |access-date=2023-02-24 |website=Mises Institute |language=en |archive-date=February 24, 2023 |archive-url=https://web.archive.org/web/20230224161616/https://mises.org/library/human-action-0/html/pp/933 |url-status=dead }}</ref>

==Publishing history==
The German-language predecessor to ''Human Action'', titled ''Nationalökonomie: Theorie des Handelns und Wirtschaftens'', first appeared in 1940. ''Human Action'' was not a direct translation of the earlier work, but used its general framework and expanded on it.<ref>{{cite book |title=Mises: The Last Knight of Liberalism |url=https://archive.org/details/bub_gb_it9c6z4bw_8C |first=Jörg Guido |last=Hülsmann |author-link=Jörg Guido Hülsmann |publisher=Ludwig von Mises Institute |location=Auburn, Alabama |year=2007 |isbn=978-1933550183 |oclc=173847313 |pages=[https://archive.org/details/bub_gb_it9c6z4bw_8C/page/n775 759]–760}}</ref>

[[Yale University Press]] published the first edition of ''Human Action'' in 1949. When production delays pushed back the planned released date of a revised and expanded second edition, [[Lyle Munson]], publisher of Bookmailer, Inc., suggested that Mises could take the book to another publisher, and offered to publish it himself. Mises used this offer as leverage to get Yale University Press to accelerate its release.<ref>{{cite web|url=https://mises.org/library/archives|first=Jeffrey M.|last=Herbener|website=[[Mises Institute]]|title=Human Action: What the Archives Tell Us|date=January 8, 1999|access-date=June 30, 2020}}</ref> The resulting 1963 edition was full of typographical errors, and another one had to be printed quickly afterwards by another editor.<ref>{{cite book|first=Margit von|last=Mises|title=My Years with Ludwig von Mises|publisher=Arlington House|location=New Rochelle, NY|date=1976|isbn=0870003682|oclc=2424897|pages=[https://archive.org/details/myyearswithludwi00vonm/page/110 110–114]|url-access=registration|url=https://archive.org/details/myyearswithludwi00vonm/page/110}}</ref> [[Regnery Publishing|Henry Regnery]] published the revised third edition in 1966.

A posthumous fourth edition was published in 1996, with revisions by [[Bettina B. Greaves]]. It is available in hardback single ([[Liberty Fund]], {{ISBN|0865976309}}) and four-volume paperback editions (Liberty Fund, {{ISBN|0865976317}}), as well as single-volume paperback (Fox & Wilkes, {{ISBN|0930073185}}). In 1998, the [[Ludwig von Mises Institute]] brought back the first edition as the "Scholar's Edition" ({{ISBN|0945466242}}). In 2010, the Institute reissued the first edition as a portable "Pocket Edition" ({{ISBN|978-1610161459}}).
