“”Lupus est homo homini[notes 1]
|—Plautus, 195 BCE|
As a philosopher Hobbes contemplated the nature of reasoning, sensation, imagination, and signification. He is considered to have been an empiricist, a nominalist, and a materialist, the latter particularly contrasting his philosophy with that of Aristotle. Hobbes agreed with Aristotle, however, that reliable knowledge was gained through reason and an understanding of the relationship of cause and effect.
Hobbes taught that human beings are naturally selfish, brutish and violent and absolute government was necessary to prevent a "war of all against all".
His principal work The Leviathan, which he wrote in English (and with liberal use of massive run-on sentences), advocated absolute government, either monarchy or assembly, as the best political system and believed a social contract was formed or should be formed to create that system. On a somewhat lighter note, these ideas were foundational traits of Hobbes in Calvin and Hobbes. He may or may not have been the product of Calvin's imagination.
In addition to the social contract theory, Leviathan is famous for introducing the concept of a "Human nature", to describe human existence before the invention of government. Hobbes guessed that this life was "solitary, poor, nasty, brutish, and short", "a war of all against all", and future enlightenment philosophers such as Locke and Rousseau took this as given, citing Hobbes. Anthropological work since has shown this to not be the case: pre-civilization human life was socially organized, cooperative, and arguably communist.<ref>
