Thomas Hobbes Quotes on Knowledge

Hobbes's Leviathan and De Corpore present a thoroughgoing materialist epistemology: thought is nothing but motion in the brain, and reasoning is calculation — the addition and subtraction of names through which language permits humans alone to construct the artificial languages of philosophy and science. Knowledge for Hobbes is of two kinds: knowledge of fact (from sense and memory) and knowledge of consequence (from reasoning), with only the second deserving the title of philosophy. The framework grounds Hobbes's nominalism — only individual bodies exist, universals are nothing but names — and the political philosophy that derives the state's authority from the rational calculation of mutual advantage.
