Leviathan by Thomas Hobbes, Chapter 17 summary
Chapter 17 of 65 · Part 2: Of the Commonwealth · 7 min to read the chapter
In Chapter 17, people seek safety by placing their strength under one representative, since promises, numbers, and temporary cooperation cannot secure lasting peace. The argument defines a commonwealth through mutual authorization, distinguishes sovereign from subject, and separates rule established by force from rule established through voluntary agreement.
What happens
- People accept restraint to preserve themselves, but natural laws and unsupported covenants cannot overcome the passions that produce conflict.
- Neither small alliances nor large crowds provide security unless one continuing judgment directs their combined strength.
- Bees and ants cooperate naturally, while human rivalry, competing judgments, and misleading speech make an enforcing power necessary.
- Each person covenants with the others to authorize one man or assembly as their representative for peace and protection.
- This union forms a commonwealth; its representative holds sovereign power, and the remaining people are subjects.
- Sovereignty arises through force or voluntary submission, producing commonwealths by acquisition or institution.
