What is Leviathan about?

Leviathan, published in 1651 in the aftermath of the English Civil War, is one of the founding texts of modern political philosophy. Hobbes wrote it under the shadow of a society that had just executed its king and descended into years of violent conflict. His central question was stark: why should anyone accept political authority at all? His answer, built on a materialist account of human nature and rational self-interest, established a framework for thinking about government, sovereignty, and legitimacy that still shapes political theory today.

Hobbes begins with psychology. Human beings are, at bottom, driven by appetite and aversion, seeking pleasure and avoiding pain. Without government, this produces the "state of nature" — a condition of perpetual competition and insecurity where life is "solitary, poor, nasty, brutish, and short." This is not a historical claim but a logical one: remove coercive authority and the result is war of all against all. No one is powerful enough to be secure, so even the strongest has reason to fear.

The solution is the social contract. Rational individuals, calculating that any government is preferable to chaos, authorize a sovereign — a monarch or assembly — to exercise power on their behalf. The key move is that this authorization is irrevocable. Hobbes opposes the idea that citizens can judge when their sovereign has become tyrannical and take action accordingly; that path leads straight back to civil war. The sovereign's authority must be absolute, or it is nothing. The one exception is direct threats to the subject's life — self-preservation is the one right that cannot be surrendered because it is the reason for entering the contract in the first place.

The third and fourth parts of Leviathan, dealing with Christian theology and the Church, were as controversial to contemporaries as the political theory. Hobbes argued that religious authority must be subordinate to the sovereign, and that much of what passed for Christian doctrine was misreading of scripture. The book was denounced as atheist by many readers, though Hobbes himself insisted on his Christianity. Reading Leviathan in full reveals a more systematic — and more theological — thinker than the selective quotations about brutish lives suggest.
