Classical Liberalism

Natural rights, individual liberty, limited government, and consent of the governed.

Overview

Classical liberalism holds that individuals possess natural rights — endowed by God or nature — to life, liberty, property, and the pursuit of happiness. These rights are pre-political: they exist before government and cannot be legitimately taken away by any government. Political authority derives solely from the consent of the governed. The purpose of government is to protect individual freedom, and power must be limited, divided, and accountable. These ideas are the philosophical foundation of the American Declaration of Independence, the Constitution, and modern constitutional democracy worldwide. Note: 'Classical liberalism' is not what Americans typically mean by 'liberal' in everyday politics. In fact, many positions associated with the modern American left — particularly those rooted in critical theory, postmodernism, and social constructionism — stand in direct philosophical contradiction to classical liberalism's foundational claims about natural rights, objective truth, and the sovereignty of the individual.

Origins

Classical liberalism emerged from the religious wars and political upheavals of 17th-century Europe. Locke's Two Treatises of Government argued that people have pre-political natural rights and may overthrow tyrannical governments. Montesquieu's separation of powers, the Scottish Enlightenment's moral philosophy, and Paine's revolutionary pamphlets translated these ideas into political reality. The American Revolution was classical liberalism's greatest practical achievement — the first time a nation was founded explicitly on philosophical principles about natural rights and the consent of the governed. Jefferson, Madison, Hamilton, and Franklin turned Enlightenment philosophy into a constitutional republic that has endured for over two centuries.
