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.
