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. (shrink)

1) Introduction. 2) The key libertarian insight into property and orthodox libertarianism’s philosophical confusion. 3) Clearer distinctions for applying to what follows: abstract liberty; practical liberty; moral defences; and critical rationalism. 4) The two dominant (‘Lockean’ and ‘Hobbesian’) conceptions of interpersonal liberty. 5) A general account of libertarianism as a subset of classical liberalism and defended from a narrower view. 6) Two abstract (non-propertarian, non-normative) theories of interpersonal liberty developed and defended: ‘the absence of interpersonal initiated imposed constraints on want-satisfaction’, (...) abbreviated to ‘no initiated imposed costs’; and ‘no imposed costs’. 7) Practical implications for both main abstract conceptions of liberty derived and compared. 8) How this positive analysis relates to morals. 9) Concluding conjectures: the main abstract theory of liberty captures the relevant interpersonal conception; the new paradigm of libertarianism solves the old one’s problems.

Most self-identified libertarians unwittingly have a moral muddle without a central factual theory of liberty. They cannot yet see that they first need to sort out what liberty is, and therefore entails if instantiated, and only after that can moral questions about it be coherently raised and tackled.
