Second Treatise of Government Summary

Second Treatise of Government is Locke’s classic argument that political power is legitimate only when it protects people’s rights under consent and law.

Main idea

Locke says people form government to protect life, liberty, and property. When rulers use power against that purpose, they break the trust that makes government legitimate.

  • Natural rights come before government.
  • Consent is the root of political legitimacy.
  • Lawmakers are limited by public good.
  • Tyranny is power used beyond right.

Modern reading

The book helps explain constitutions, rights, emergency powers, property debates, and the idea that public office is a trust rather than personal ownership.

Best section to start with

Start with Chapter 2 for natural rights, Chapter 5 for property, and Chapter 19 for Locke’s argument about resistance.
