Leviathan

Thomas Hobbes' Leviathan is the foundation of modern political philosophy, articulating the social contract theory that would shape all subsequent thinking about the relationship between the individual and the state. His famous description of life in the state of nature as "solitary, poor, nasty, brutish, and short" remains one of the most memorable formulations in the history of political thought.

Written during the upheaval of the English Civil War, Leviathan argues for absolute sovereignty as the only guarantee against the chaos of the natural condition. The work laid the foundation of social contract theory, influencing John Locke, Jean-Jacques Rousseau, and the entire tradition of modern political philosophy. It remains a core text in political science curricula around the world.
