_Adversus “Adversus Homo Economicus_”: Critique of the “Critique of Lester’s Account of Instrumental Rationality”

This essay goes through Frederick 2015 (the critique) in some detail, responding to the various paraphrases and criticisms therein. It is argued that in each case the critique is mistaken about what Lester 2012 (Escape from Leviathan: EfL) says, or about what the critique presents as a sound criticism, or both. Introduction: the three problems with the critique and the philosophical problem that EfL is attempting to solve. “Abstract”: the critique’s confusion about EfL’s aprioristic theory of instrumental rationality. There are then detailed replies (too many and too diverse to summarise) to quotations from the critique’s confused interpretations and criticisms under the following headings (quoted from the critique): “2. Instrumental Rationality”; 3. Weakness of Will”; “4. Desires and Values”; “5. Free Will”; “6. Self-Interest”; “7. Maximisation”; “8. Morals”. Finally, in “9. Conclusion”, the philosophical problem for economics is briefly restated. The philosophical interpretation of homo economicus in EfL (as with its overall philosophical theory of libertarianism) has yet to be given adequate critical consideration.
