David Friedman is an economist, political philosopher, and the author of many books including The Machinery of Freedom, wherein he lays the groundwork for a society based exclusively on voluntary transactions. In this Exploring Liberty lecture, Friedman discusses the main premises of The Machinery of Freedom (PDF) and offers a few additional conclusions he has reached in the years after the first edition of the book was published in 1973.
