Leviathan is the name of an ancient sea monster mentioned in the Bible, an embodiment of the elements that suppress human will.
Leviathan is the name Thomas Hobbes gave to the modern state, where people are obliged to sacrifice some of their natural desires and rights for their own safety. The law of Leviathan is the law of every man.
Thomas Hobbes's 'Leviathan' is one of the most important philosophical treatises on the theory of power, having had a colossal influence on the development of culture, philosophy, and the political structure of modern society.
