Leviathan, written by Thomas Hobbes in 1651, is a political treatise that outlines Hobbes' view of society and the role of government. Hobbes believed that humans were naturally selfish and violent, and that life in the state of nature, without any form of government, would be "solitary, poor, nasty, brutish, and short." To avoid this chaos, Hobbes argued that individuals should enter into a social contract with a sovereign authority, giving up some of their natural rights in exchange for protection and security. The sovereign, whether a monarch or a democratically elected government, is granted absolute power to maintain order and prevent conflict. Hobbes' theory of the social contract has been influential in political philosophy, and his views on the nature of humans and the role of government continue to be debated today. He believed that the ultimate goal of government was to ensure peace and stability, and that the sovereign's power should be unlimited to achieve this end. Leviathan also discusses Hobbes' views on religion, and he argued that the state should have control over religious matters to prevent dissent and maintain unity. Overall, Leviathan is a seminal work in political philosophy that has shaped discussions on the nature of government and society for centuries.
