Hobbes wrote several versions of his political philosophy, including The Elements of Law, Natural and Politic (also under the titles Human Nature and De Corpore Politico) published in 1650, De Cive (1642) published in English as Philosophical Rudiments Concerning Government and Society in 1651, the English Leviathan published in 1651, and its Latin revision in 1668.
Others of his works are also important in understanding his political philosophy, especially his history of the English Civil War, Behemoth (published 1679), De Corpore (1655), De Homine (1658), Dialogue Between a Philosopher and a Student of the Common Laws of England (1681), and The Questions Concerning Liberty, Necessity, and Chance (1656).
All of Hobbes’s major writings are collected in The English Works of Thomas Hobbes, edited by Sir William Molesworth (11 volumes, London 1839-45), and Thomae Hobbes Opera Philosophica Quae Latina Scripsit Omnia, also edited by Molesworth (5 volumes; London, 1839-45). Oxford University Press has undertaken a projected 26 volume collection of the Clarendon Edition of the Works of Thomas Hobbes. So far 3 volumes are available: De Cive (edited by Howard Warrender), The Correspondence of Thomas Hobbes (edited by Noel Malcolm), and Writings on Common Law and Hereditary Right (edited by Alan Cromartie and Quentin Skinner). Readers new to Hobbes should begin with Leviathan, being sure to read Parts Three and Four, as well as the more familiar and often excerpted Parts One and Two. There are many fine overviews of Hobbes’s normative philosophy, some of which are listed in the following selected bibliography of secondary works.
