This Liberty Law Talk is with philosopher Eric Mack on Friedrich Hayek’s 1973 magnum opus, Law, Legislation and Liberty. Hayek’s significant trilogy distinguishes between law and legislation, considers the appropriate rule of judges within a spontaneous order, observes the difficulties of even defining social justice, and attempts to set forth the principles of a new constitutional order for a free people. This conversation considers at length the major ideas that Hayek advances in his incredible work on the principles of law and just order.
