Thomas Hobbes was an English philosopher born in 1588 who is considered one of the founders of modern political philosophy. He studied at Oxford University and traveled throughout Europe, becoming interested in different forms of government. His most famous work was Leviathan, in which he argued that human nature is selfish and violent, and that life in a state of nature would be "solitary, poor, nasty, brutish and short." Hobbes believed people consent to a social contract establishing an absolute sovereign, such as a monarch, to maintain order and security. He viewed sovereignty as the foundation of civil government and advocated for strong, centralized states with absolute power.
