Empiricism

• Locke is a founder of British Empiricism.

• Governments that fail to protect these rights are illegitimate

Social Contract Theory

• Locke's political philosophy is rooted in social contract theory
• Social contract theory suggests that individuals consent to surrender some freedoms to a government
