Here is my take on Tyler Cowen’s views on libertarian thinkers who are either overrated or underrated in shaping the libertarian tradition. Please be aware that I think libertarianism and classical liberalism are two different strands of liberal thought, as argued in more detail in an earlier post here at NOL and in my latest book. Please also note that my judgement will be particularly informed by their views on international relations.

Overrated:

1. Hans-Hermann Hoppe – completely esoteric ideas about international relations, especially his erroneous and ill-thought idea about private defence through private insurance companies.
2. Deepak Lal – no complaints about his general work, but his praise for empires was deeply disturbing, even though he meant well. Liberalism and globalization do not need empires, no matter how civilized – in the Oakeshottian meaning – they are meant to be.
3. Ron Paul – I admire Ron Paul in many ways, but his ideas for ‘a foreign Policy of freedom’ are not much better than Hoppe’s. ‘peace, commerce, and honest friendship’: nice Jeffersonian goals, bad underlying analysis, not least about human nature.

Underrated:

1. Friedrich Hayek – a far more sophisticated thinker on international relations than he is ever given credit for.
2. Adam Smith – nowadays erroneously equated with ‘trade leads to peace’ fairly tales. Yet any reader of the complete two volumes of the Wealth of Nations recognizes that the book is also a lot about war and foreign policy, as are his Lectures on Jurisprudence and even a bit in The Theory of Moral Sentiments. Together these make for a full and sophisticated position on international affairs.
3. David Hume – basically the same as Smith.
4. Robert Jackson – ok, I am taking liberties here. I do not think Jackson would consider himself a classical liberal or libertarian. But his writings on international relations are important and often have a classical liberal leaning, especially The Global Covenant.
