"George Smith's lectures on classical liberalism had a profound effect on my thinking. Now, at long last, others may profit from his prodigious learning in this absolutely 'must read' book for anyone interested in modern libertarianism and its historical roots. Clear, accessible, balanced, and powerfully reasoned."
--Randy E. Barnett, author of The Structure of Liberty: Justice and the Rule of Law

"This is a lucid, concise, but at the same time a deep overview of the origins and structure of classical liberal thought. With a fluid and engaging style, Smith corrects many of our modern misconceptions about how early liberals understood themselves and the terms on which they debated. Anyone interested in liberal thought, whether in its 'classical', modern 'high liberal', or libertarian forms, will find this a valuable resource. Even critics of classical liberalism will find, thanks to Smith, that classical liberal thought contains a great deal of forgotten wisdom."
--Jason Brennan, author of Libertarianism: What Everyone Needs to Know

“George H. Smith is an independent scholar who for many decades has lectured and written about the history of classical liberal and libertarian ideas. The System of Liberty is his first extended take on this history to be published by a high-level academic press—a tribute both to Smith’s dogged scholarship and to the rise in the respectability of the libertarian tradition he explains and espouses…the information and analysis are always interesting.” -Brian Doherty, Reason Magazine
