How did natural-law ideas influence limits on government power?

Natural-law ideas fundamentally transformed the understanding of government power by asserting that individuals possess inalienable natural rights—such as life, liberty, and property—that exist independently of, and prior to, any state authority.12

This doctrine influenced limits on government power in several key ways:

• Social Contract Theory: Thinkers like John Locke argued that government authority is derived from a social contract between rulers and the governed. Because individuals only surrender the right to enforce their own rights to the state, the government’s power is limited to protecting the public good and preserving these inherent rights.132
• Constitutionalism: The belief that government must be limited led to the development of written constitutions designed to protect individual freedoms. These documents established institutional structures, such as the separation of powers and checks and balances, to prevent arbitrary rule.324
• Rule of Law: Natural law provided a moral and legal standard against which positive laws could be judged. If a government failed to secure these fundamental rights, it was viewed as illegitimate, providing a rationale for resistance or revolution.152

Ultimately, these ideas shifted the purpose of political association from the absolute power of a sovereign to the protection of the individual, forming the bedrock of modern liberalism and constitutional democracy.132
