Truth

About what is true.

In economic terms, truth applies to economic events (see also Valueflows and hREA), fulfillments,

Related to p2p's motto: verify, do not trust.

Also related to Edgar Morin's epistemology of complexity.

Key Epistemological Essays in Economics

1. Friedman: “The Methodology of Positive Economics” (in Essays in Positive Economics, 1953)
   1. Core insight: Economics should focus on positive, not normative, statements—evaluating theories by predictive power, simplicity, and 'fruitfulness' rather than realistic assumptions.
   2. Epistemological contribution: Establishes a pragmatic criterion—successful prediction—as the basis of theoretical legitimacy.
2. Hayek: “The Use of Knowledge in Society” (1945)
   1. Core insight: Knowledge is decentralized and tacit; no central planner can aggregate all dispersed information. Market prices coordinate actions using local information.
   2. Epistemological contribution: Emphasizes dispersed cognition, the limits of formal knowledge, and how markets serve as emergent information processors.
3. Lionel Robbins: An Essay on the Nature and Significance of Economic Science (1932, 1935)
   1. Core insight: Defines economics as the study of human behavior as a relationship between ends and scarce means; explicitly value-neutral and focused on scarcity.
   2. Epistemological contribution: Clarifies the scope of economic inquiry and separates positive from normative considerations.
4. Mises: Theory and History (1957)
   1. Core insight: Advocates methodological dualism: social sciences must treat individual motivations and contexts separately from natural sciences. Introduces praxeology (the logic of human action), and thymology (historical understanding of motive as perceived by the actor).
   2. Epistemological contribution: Emphasizes the universal, a priori structure of human action, while recognizing context-specific historical reconstructions.
5. Stapleford: “Historical Epistemology and the History of Economics: Views Through the Lens of Practice” (2017)
   1. Core insight: Proposes treating economics as a social practice, adopting the lens of historical epistemology (à la Foucault, Bachelard).
   2. Epistemological contribution: Suggests that understanding economics requires analyzing practical contexts, disciplinary norms, and historiographic practices, not just ideas in abstraction.
6. Ostillio: “A Brief Epistemology of Economic Models” (2016)
   1. Core insight: Highlights how economic models exhibit untenable determinism, inadequate handling of uncertainty, and failure to deal with the identification problem.
   2. Epistemological contribution: Argues that over-abstraction undermines explanatory power and consistency of economic modeling; calls for epistemic humility and better treatment of indeterminacy.
7. Sagal: “Epistemology of Economics” (1977)
   1. Core insight: Critically examines three methodological positions:
      1. Ultra-empiricism (Hutchison)
      2. Moderate empiricism (Friedman)
      3. Extreme a priori (Robbins, Mises)
   2. Epistemological contribution: Offers meta-level analysis of the strengths and weaknesses of these traditions; suggests that even a priori approaches retain value in certain contexts.
