1. The most important Leveller writings have been collected in Tracts on Liberty in the Puritan Revolution, ed. William Haller (New York 1933–4; reprinted 1965); Leveller Manifestoes of the Puritan Revolution, ed. Don M. Wolfe (New York 1944; repr. 1967); The Leveller Tracts, 1647–1653, ed. William Haller and Godfrey Davies (New York 1944; repr. Gloucester, Mass. 1964).
2. The text of the Putney Debates was printed by C. H. Firth in vol. i of The Clarke Papers (Camden Soc. 1891–1901). It was re-edited by A. S. P. Wood-house in Puritanism and Liberty (1938).
3. The best modern accounts of the Leveller movement are Joseph Frank, The Levellers (Cambridge, Mass. 1955) and Brailsford (the most detailed treatment so far). Theodore Calvin Pease, The Leveller Movement (Washington, D.C. 1916; repr. Gloucester, Mass. 1965) is still strong on the constitutional aspects. Valuable studies of Leveller thought can also be found in W. Schenk, The Concern for Social Justice in the Puritan Revolution (1948); D. B. Robertson, The Religious Foundations of Leveller Democracy (New York 1951); Zagorin, Political Thought; Christopher Hill, ‘The Norman Yoke’, in Puritanism and Revolution (1958); Pauline Gregg, Free-born John. A Biography of John Lilburne (1961). Howard Shaw, The Levellers (1968) is a recent summary.
4. Professor C. B. Macpherson’s interpretation of the Levellers comes in his The Political Theory of Possessive Individualism (Oxford 1962) pp. 107–59. His arguments have been endorsed by Hill, ‘Pottage for Freeborn Englishmen: Attitudes to Wage Labour in the sixteenth and seventeenth centuries’, in Socialism, Capitalism and Economic Growth, ed. C. H. Feinstein (Cambridge 1967). They have been criticised by A. L. Merson, ‘Problems of the English bourgeois revolution’, in Marxism Today, vii (1963); Peter Laslett, ‘Market society and political theory’, HJ, vii (1964), pp. 150–4; J. C. Davis, ‘The Levellers and Democracy’, p&p, xl (1968); and Roger Howell, Jr and David E. Brewster, ‘Reconsidering the Levellers: the evidence of The Moderate’, p&p,xlvi (1970). The most thorough-going critique is A. L. Morton, Leveller Democracy — Fact or Myth? (Our History, pamphlet no. 51, 1968; repr. in his book, The World of the Ranters [1970]).
