Leviathan by Thomas Hobbes...... Leviathan or The Matter, Forme and Power of a Common Wealth Ecclesiasticall and Civil-commonly referred to as Leviathan-is a book written by Thomas Hobbes (1588-1679) and published in 1651 (revised Latin edition 1668). Its name derives from the biblical Leviathan. The work concerns the structure of society and legitimate government, and is regarded as one of the earliest and most influential examples of social contract theory. Leviathan ranks as a classic western work on statecraft comparable to Machiavelli's The Prince. Written during the English Civil War (1642-1651), Leviathan argues for a social contract and rule by an absolute sovereign. Hobbes wrote that civil war and the brute situation of a state of nature ("the war of all against all") could only be avoided by strong, undivided government. Hobbes begins his treatise on politics with an account of human nature. He presents an image of man as matter in motion, attempting to show through example how everything about humanity can be explained materialistically, that is, without recourse to an incorporeal, immaterial soul or a faculty for understanding ideas that are external to the human mind. Hobbes proceeds by defining terms clearly, and in an unsentimental way. Good and evil are nothing more than terms used to denote an individual's appetites and desires, while these appetites and desires are nothing more than the tendency to move toward or away from an object. Hope is nothing more than an appetite for a thing combined with opinion that it can be had. He suggests the dominant political theology of the time, Scholasticism, thrives on confused definitions of everyday words, such as incorporeal substance, which for Hobbes is a contradiction in terms.
