Thomas Hobbes' timeless account of the human condition, first developed in The Elements of Law (1640), which comprises Human Nature and De Corpore Politico, is a direct product of the intellectual and political strife of the seventeenth century. His analysis of the war between the individual and the group lays out the essential strands of his moral and political philosophy later made famous in Leviathan. This first ever complete paperback edition of Human Nature and De Corpore Politico is also supplemented by chapters from Hobbes' later work De Corpore and "The Three Lives," never before published together in English.
