Thomas Hobbes argues for a social contract and rule by an absolute sovereign. Influenced by the English Civil War, Hobbes wrote that chaos or civil war-situations identified with a state of nature and the famous motto Bellum omnium contra omnes ("the war of all against all")-could only be averted by strong central government. He thus denied any right of rebellion toward the social contract, which would be later added by John Locke and conserved by Jean-Jacques Rousseau. (However, Hobbes did discuss the possible dissolution of the State. Since the social contract was made to institute a state that would provide for the "peace and defense" of the people, the contract would become void as soon as the government no longer protected its citizens. By virtue of this fact, man would automatically return to the state of nature until a new contract is made).

Thomas Hobbes' Leviathan is arguably the greatest piece of political philosophy written in the English language. Written in a time of great political turmoil (Hobbes' life spanned the reign of Charles I, the Civil Wars, the Commonwealth and the Protectorate, and the Restoration), Leviathan is an argument for obedience to authority grounded in an analysis of human nature. Since its first publication in 1991 Richard Tuck's edition of Leviathan has been recognised as the single most accurate and authoritative text, and for this revised edition Professor Tuck has provided a much amplified and expanded introduction, which will provide students unfamiliar with Hobbes with a cogent and accessible introduction to this most challenging of texts. Other vital aids to study include an extensive guide to further reading, a note on textual matters, a chronology of important events and brief biographies of important persons mentioned in Hobbes' text.
