In Leviathan, the first great work of philosophy in English, Thomas Hobbes presents the fundamentals of his beliefs about language, epistemology, and an extensive treatment of revealed religion and its relation to politics. Beginning with premises that were sometimes controversial, Hobbes derives shocking conclusions. Hobbes's contemporaries recognized the power of the arguments in Leviathan and many of them wrote responses to it; selections from many of these responses 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 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. In this revised edition of Hobbes's classic work, A.P. Martinich improves the punctuation for clarity. He has also added new notes for readers, extensive cross references, and a substantial part of Hobbes's reply to Bramhall's The Catching of Leviathan.
