Thomas Hobbes

Materialist of the social contract — the state as escape from the war of all against all.

EmpiricismEarly ModernEnglish1588–1679 CE◦ Wiltshire (England)16th century CE

Overview

An English philosopher whose Leviathan is the founding text of modern political philosophy. A thoroughgoing materialist, Hobbes held that everything, including thought, is matter in motion. Writing amid the English Civil War, he argued that without a common power humans fall into a 'state of nature' — a war of all against all in which life is 'solitary, poor, nasty, brutish, and short'. To escape it, people rationally consent to surrender their liberty to a sovereign whose absolute authority secures peace: the social contract.

What they supported — and why

Materialism and mechanism

SupportedEverything that exists is body in motion; sensation, thought, and desire are motions in the body.

WhyOnly bodies can act and be acted upon, so a consistent natural philosophy must explain even mind mechanically.

The state of nature is a war of all against all

SupportedWithout a common power, rough equality and scarcity make life a perpetual war of everyone against everyone, and life 'solitary, poor, nasty, brutish, and short'.

WhyAbsent enforcement, each person's right to self-preservation and mutual fear make conflict inevitable, and no security or civilization is possible.

The social contract and the sovereign

SupportedPeople rationally agree to give up their natural liberty to an absolute sovereign who enforces peace and law.

WhyOnly an undivided, overawing power can guarantee the security that everyone most wants, so submitting to it is the rational price of peace.
