This work is a classic dialogue between two philosophers, with the unusual twist that it was actually conducted, not fabricated, by two different philosophers. It presents in a conversational tone the various crucial and not so crucial aspects of the topic of political liberty and what if any value it has for us. The topics covered range from the main theme to such others as the nature of goodness, the open question argument (G.E. Moore), the nature of conceptual knowledge, whether being rational might be the highest moral good and what it entails, how to judge theories of mortality, the difference between goodness and moral goodness, and much more. Both undergraduate and graduate students of philosophy and in particular political philosophy, will find this book invaluable.
