Thomas Hobbes

Hobbes built a materialist, mechanistic philosophy of nature, mind, and politics, arguing that all reality, including thought and desire, consists of matter in motion. On this basis he constructed, above all in "Leviathan" (1651), a social-contract account of political authority in which self-interested individuals fleeing the violent "state of nature" transfer their natural right of self-government to an absolute, undivided sovereign as the only guarantor of peace.

Depth: In-depth

How can conflict give way to authority?

Hobbes asks how vulnerable and roughly equal persons, lacking a common judge, can escape a condition in which distrust and anticipated violence make security unstable. The problem is institutional: private judgment alone cannot reliably settle rights or enforce covenants.

Authorization secures a common power

In Leviathan XIII–XV, fear, competition, and uncertainty produce war even without constant fighting. Laws of nature recommend peace, but covenants need enforcement. In chapters XVI–XVIII, each covenanter authorizes a sovereign representative, converting a multitude into a political person.

Must security license absolute authority?

Critics ask why protection requires indivisible and effectively absolute sovereignty, and whether authorization can bind dissenters. Hobbes's own reservation of resistance when life is directly threatened also tests the boundary between unconditional obedience and self-preservation.

Definition, construction, and counterfactual

Hobbes defines person, covenant, liberty, and sovereignty, then constructs political order from passions and strategic vulnerability. The state of nature is an analytical comparison as well as a claim about recognizable conditions of civil war and insecure international relations.

Civil war and contested allegiance

Leviathan was written amid the English Civil Wars and Hobbes's exile in Paris. Competing religious and political authorities made the question of final judgment urgent, without reducing his systematic account of matter, psychology, and representation to a report on one conflict.

A durable challenge about order

Hobbes has been read as an absolutist, a theorist of representation, and a precursor of liberal individualism. Objections focus on consent, domination, and whether peace can justify stripping institutions of divided accountability; later contract theories repeatedly revise his setup.

Contributions to threads

Political order becomes possible when individuals authorize a common sovereign capable of enforcing covenants and providing security.

1651 CE · certain

Hobbes moves from equal vulnerability and rational distrust to laws of nature favoring peace, then argues that only an enforceable covenant and undivided representative authority can stabilize cooperation while leaving a narrow liberty of self-preservation.

Intellectual setting

Hobbes lived through the English Civil War (1642-1651), tutored the future Charles II during his own exile in Paris, and wrote "Leviathan" partly as a response to the political and religious chaos of the period; his materialism and denial of incorporeal substance provoked charges of atheism, and the book was formally condemned and burned by Oxford University in 1683.

Key ideas

The state of nature and the social contract

Hobbes argued that without a common power to keep people "in awe," human life devolves into a war of every man against every man in which life is "solitary, poor, nasty, brutish, and short"; rational, self-interested individuals therefore contract with one another to erect and obey an absolute sovereign who alone can guarantee peace.

Materialist psychology of the passions

Hobbes explained human motivation mechanistically, as appetites and aversions produced by matter in motion, grounding his politics in a naturalistic theory of human psychology and desire rather than in Aristotelian teleology or theological natural law.

Authorization and sovereignty

Individuals covenant with one another to authorize a person or assembly to act in their name; the sovereign is not a party to that covenant, which underwrites undivided and continuing authority while subjects retain an inalienable resistance to direct threats to life.

Liberty under law

Liberty is the absence of external impediments, so subjects remain free wherever law is silent; Hobbes combines this domain of action with a stringent duty to obey the power that secures peace.

Legacy

Hobbes's "Leviathan" became a foundational text of modern political philosophy, shaping the later contract theories of Locke and Rousseau and the modern study of sovereignty and the state; Hobbes is now regarded as the founder of the modern social-contract tradition and a central figure in debates about political authority and human nature.
