Thomas Hobbes (1588-1679) was an English philosopher who is considered one of the founders of modern political philosophy. He studied at Oxford University and traveled throughout Europe, experiencing different forms of government. Hobbes believed humans were inherently selfish and without rules or authority would live in a "war of all against all." He argued the best form of government was an absolute monarchy that imposed order through a strong central authority figure like a king. His most famous work was Leviathan, published during the English Civil War, where he made the case that people could not be trusted to govern themselves and needed an absolute ruler to maintain peace and security.
