Leviathan

Thomas Hobbes (1588 -1679), was an English philosopher who is considered one of the founders of modern political philosophy.] Hobbes is best known for his 1651 book Leviathan, which established the social contract theory that has served as the foundation for most later Western political philosophy. In addition to political philosophy, Hobbes also contributed to a diverse array of other fields, including history, jurisprudence, geometry, the physics of gases, theology, ethics, and general philosophy. 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 unsentimentally. 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.
