Although it has long been recognised that Sieyes' What is the Third Estate?, translated for this edition by Michael Sonenscher, was the key text of the French Revolution, only recently has Sieyes come to be seen as one of the central figures in the formation of modern liberalism. This timely edition, which also includes three other works Sieyes produced in 1789 -- his 'Essay on Privileges', 'Views of the Executive Means', and the text of his debate with Tom Paine -- will be of value to anyone interested in the origins and character of modern liberalism, the history and analysis of political thought, or the history of the French Revolution.
