Thomas Hobbes’s Leviathan is the greatest work of political philosophy in English and the first great work of philosophy in English. Beginning with premises that were sometimes controversial, such as that every human action is caused by the agent’s desire for his own good, Hobbes derived shocking conclusions, such as that the civil government enjoys absolute control over its citizens and that the sovereign has the right to determine which religion is to be practiced in a commonwealth. Hobbes’s contemporaries recognized the power of arguments in Leviathan and many of them wrote responses to it; selections by John Bramhall, Robert Filmer, Edward Hyde, George Lawson, William Lucy, Samuel Pufendorf, and Thomas Tenison are included in this edition.

Leviathan is divided into four parts: In the first part, Of Man, Hobbes presents a view of human beings and of the natural world in general that is materialistic and mechanistic. In the second part, Of Commonwealth, he defends the theory of absolute sovereignty, the view that the government has all the political power and has the right to control any aspect of life. In the third part, Of a Christian Commonwealth, he critiques concepts like revelation, prophets, and miracles in such a way that it becomes doubtful whether they can be rationally justified. In the fourth part, Of the Kingdom of Darkness, he explains various ways in which priestly religion has corrupted religion and transgressed the rights of the sovereign.
