No arts; no letters; no society; and, which is worst of all, continual fear and danger of violent death; and the life of man, solitary, poor, nasty, brutish, and short.

Leviathan, part 1, chapter 13

Thomas Hobbes lived through the English Civil War, and his political philosophy is a response to that experience. His Leviathan (1651) argues that without government people would live in a war “of every man against every man”, in which life would be “solitary, poor, nasty, brutish, and short”. To escape it, they agree to hand their natural freedom to a sovereign whose power is absolute.

His interests reached far beyond politics. He defended materialist, nominalist and empiricist views against Descartes and the Aristotelians, clashed with Robert Boyle over experimental science, and translated Thucydides’ history of the Peloponnesian War into English.

Key ideas

The state of nature
Without a government to settle disputes, each person judges for themselves, and life is a “condition of war”. The life of man would be “solitary, poore, nasty, brutish, and short”.
The laws of nature
Reason shows everyone that peace is good, so we should seek peace and do what secures it when it is safe to do so. These “Lawes of Nature” come down to not treating others as we wouldn’t have them treat us.
The absolute sovereign
The only escape from the state of nature is to submit to a mutually recognised public authority. To avoid collapsing back into war, people should treat their sovereign as having absolute authority.
Reasoning as computation
Hobbes described reasoning as computation, and sketched the computations he thought go on when we reason. The idea has been linked to Leibniz and to modern computational theories of mind.
Materialism
Human beings, minds included, are entirely material. Later Hobbes came to think that even God is a kind of material, extended being. Few of his contemporaries shared this view.
