3.4 Philosophical Foundations of the American Revolution

The American Revolution drew on Enlightenment ideas about natural rights, consent of the governed, republicanism, and limits on authority. Colonists used those ideas to challenge British rule and justify independence, even as many groups remained excluded from the Revolution's promises.

What to Know About Philosophical Foundations of the American Revolution

• Locke tied government to protecting natural rights, Montesquieu proposed separated powers to prevent tyranny, and Rousseau argued that legitimate authority depends on the consent of the governed.
• Books, pamphlets, and correspondence spread Enlightenment ideas in the colonies, while Great Awakening beliefs complemented ideas about individual rights and representative government.
• Thomas Paine's Common Sense used accessible language to argue against monarchy and helped shift colonial thinking from reform within the British system to independence.
• The Declaration of Independence, adopted on July 4, 1776, asserted unalienable rights and the principle that government gets its powers from the consent of the governed.
• Revolutionary ideas shaped the Constitution and Bill of Rights, inspired later democratic movements, and helped define an American identity based on shared political ideals.

The Enlightenment

The Enlightenment was a philosophical movement that emerged in 18th-century Europe and emphasized reason, individualism, and skepticism. It laid the foundations for many of the values and ideals that shaped the American Revolution.

Central Ideas of the Enlightenment

"Reason over Revelation" is a core principle of Enlightenment thought, signifying how people began looking to human reason, rather than divine authority, to understand the world and solve problems. From this emphasis on reason emerged new political ideas about natural rights and the proper function of government.

✨ Key Enlightenment thinkers whose ideas influenced the American Revolution include:

• John Locke argued that people have certain inalienable natural rights, including life, liberty, and property. These rights are not granted by government but exist naturally and cannot be taken away. Locke proposed that governments exist to protect these rights, and if a government fails to do so, the people have the right to alter or abolish it.
• Thomas Hobbes developed the theory of the social contract, arguing that in the natural state, life was "solitary, poor, nasty, brutish, and short." People form governments to escape this state and ensure their safety. Under the social contract, people surrender some freedoms in exchange for security and order.
• Baron de Montesquieu proposed the separation of powers to prevent tyranny. He argued that government should be divided into different branches (executive, legislative, judicial), each with distinct powers and responsibilities. This concept heavily influenced the structure of the American government.
• Jean-Jacques Rousseau expanded on social contract theory, emphasizing the importance of the common good. He argued that legitimate political authority comes from the consent of the governed and that government should represent the "general will" of the people.

The Social Contract Theory suggests that people agree to give up some individual freedoms to live under a government that protects their remaining rights. According to this theory, government exists to serve the common good and protect citizens' natural rights.

Enlightenment Ideas in Colonial America

Enlightenment ideas spread through the American colonies through books, pamphlets, and correspondence with European intellectuals. Colonial leaders including Benjamin Franklin, John Adams, Thomas Jefferson, James Madison, and Alexander Hamilton were deeply influenced by Enlightenment philosophy.

Colonial leaders increasingly rejected the notion of the divine right of kings and aristocratic privilege. Instead, they embraced ideas about:

• Individual rights
• Government by consent
• Representation in government
• The rule of law
• Checks on government power

Religious Influences

While Enlightenment ideas emphasized reason, religious beliefs also played an important role in shaping revolutionary thought. Many colonists believed that God had granted them liberty and that America had a special purpose or destiny.

The Great Awakening, a religious revival that swept through the colonies in the mid-18th century, reinforced ideas about:

• Individual conscience
• Questioning established authority
• Spiritual equality
• Moral self-improvement

These religious concepts complemented Enlightenment ideas about individual rights and representative government, creating a powerful intellectual foundation for revolution.

Thomas Paine's "Common Sense"

Published in January 1776, Thomas Paine's pamphlet "Common Sense" was a pivotal document that helped persuade many colonists to support independence.

Paine, a recent immigrant from England, wrote in a direct, accessible style that appealed to ordinary colonists. His key arguments included:

• The absurdity of an island (Britain) ruling a continent (America)
• The corrupt and tyrannical nature of monarchy as a system of government
• The economic benefits of independence and free trade
• The moral necessity of establishing a republican government in America

"Common Sense" sold approximately 150,000 copies within a few months, an extraordinary number for the time. Its widespread popularity helped transform colonial thinking from reform within the British system to outright independence.

Paine's famous quote captured his central argument:

The Declaration of Independence

The influence of Enlightenment ideals and Paine's "Common Sense" culminated in the Declaration of Independence, which expressed the philosophical justification for American independence.

On June 7, 1776, Richard Henry Lee introduced a resolution to the Second Continental Congress calling for independence from Great Britain. In mid-June, before the resolution passed on July 2, Congress appointed a committee that included Thomas Jefferson to draft a formal declaration explaining the colonies' actions to the world.

The Declaration of Independence, adopted on July 4, 1776, represents the clearest expression of Enlightenment principles in American founding documents. It includes:

• The assertion that "all men are created equal"
• The concept of "unalienable rights" including "life, liberty, and the pursuit of happiness"
• The principle that governments derive "their just powers from the consent of the governed"
• The right of revolution when a government becomes destructive of these ends

The Declaration served multiple purposes:

• A formal announcement of independence to other nations
• An appeal for international support and recognition
• A philosophical statement of revolutionary principles
• A rallying cry for Americans to support the revolutionary cause

Legacy of Revolutionary Ideas

The philosophical foundations of the American Revolution have had a lasting impact:

• They provided the intellectual framework for the Constitution and Bill of Rights
• They established enduring American values of liberty, equality, and self-government
• They inspired later democratic movements around the world
• They created an American identity based on shared political ideals rather than ethnic or religious identity

These revolutionary ideas continue to shape American political thought and national identity, representing what Thomas Jefferson called "the American mind." The ideas in "Common Sense" and the Declaration of Independence, especially natural rights and republican government, echoed across all of American history, and Americans kept returning to them to understand the ideals on which the nation was founded.
