Philosophical Foundations of the American Revolution

AMSCO Topic 3.4

AP US History Study Guide — Outside-Research Edition

Learning Objective: Explain how and why colonial attitudes about government and the individual changed in the years leading up to the American Revolution. Thematic focus (College Board framework): American and National Identity (NAT) · Social Structures (SOC) This guide keeps AMSCO's own content as its backbone and expands it with outside research. Every fact beyond what AMSCO Topic 3.4 says is tagged the moment it appears: OUTSIDE SOURCE — Beyond AMSCO: [claim] — [source]. Only sources actually found this session are cited. Nothing below is invented. One correction is flagged below where the original condensed version of this guide oversimplified a historian's actual argument — see the Historiography section.

Big Picture

Beyond specific tax grievances (Topic 3.3), colonists needed an intellectual justification for breaking from Britain entirely — not just resisting one tax, but rejecting monarchy itself. That justification came from Enlightenment thought and was popularized for ordinary readers by Thomas Paine.

Enlightenment Ideas

The Enlightenment peaked in the mid-18th century — exactly when future founders (Washington, Jefferson, Franklin, Adams) were coming of age, shaping their worldview.

Deism: God created natural laws governing the universe but doesn't intervene directly in human affairs (contrast with traditional Christian belief in an interventionist God). People are free to make their own choices.

Rationalism: Trust in human reason to understand the natural world and solve problems — emphasis on science and study of human behavior over strict traditional/biblical interpretation.

Social Contract: The idea that government is an agreement among people to promote liberty and equality, with power flowing "from below" (the people) rather than "from above" (divine right of kings). Developed by John Locke, extended by Jean-Jacques Rousseau. This was a radical break from the traditional belief that monarchs ruled because God chose them. OUTSIDE SOURCE — Beyond AMSCO — Locke's actual argument, in enough detail to quote: Locke's Second Treatise of Government (1689) argues government is legitimate only when based on the consent of the governed, and that a just government cannot violate people's natural rights to life, liberty, and property. Locke wrote that "no one can be put out of [the state of nature] and subjected to the political power of another, without his own consent." The Declaration of Independence (Topic 3.5) echoes this framework "almost point by point": people are created equal with inherent rights, governments derive their just powers from the consent of the governed, and the people may alter or abolish a government that becomes destructive of those ends. When you write about the Declaration, naming this specific Lockean structure (natural rights

→ consent

→ right of revolution when

government violates the contract) is worth more than just saying "influenced by Locke." — FEE, "John Locke: Natural Rights to Life, Liberty, and Property"; Pepperdine School of Public Policy, "Founding Documents: Second Treatise".

OUTSIDE SOURCE — Beyond AMSCO — a third Enlightenment thinker AMSCO doesn't name but you need for

Topic 3.8: Baron de Montesquieu, in The Spirit of the Laws (1748), argued that liberty requires separating the power to make laws, execute laws, and judge disputes into different hands, so that "power should be a check to power." His influence on the Framers was enormous — at the 1787 Constitutional Convention, only the Bible was quoted more often, and James Madison called him "the oracle who is always consulted and cited" on separation of powers. Madison's own Federalist No. 47 is essentially a long argument about how to correctly apply Montesquieu's theory to the new Constitution. Locke supplies the why of the Revolution (natural rights, consent, right to overthrow unjust government); Montesquieu supplies the structural how of the government built afterward (see Topic 3.8's separation of powers and Topic 3.9). Keep them straight — they answer different questions. — Constitution Center, "Montesquieu, The Spirit of the Laws (1748)"; Law & Liberty, "How the Founders Read Montesquieu".

Thomas Paine's Common Sense (January 1776)

Paine, born in England, argued in plain, forceful language that:

It was illogical ("contrary to common sense") for a large continent to be ruled by a small, distant island. The colonies should become fully independent states.

Unlike earlier writers who blamed only Parliament and the king's ministers, Paine directly attacked King George III and the very idea of monarchy.

Its accessible language for common readers helped it spread rapidly and ignite public demand for independence — a major turning point AMSCO APUSH Unit 3 2 of 5

in colonial opinion.

OUTSIDE SOURCE — Beyond AMSCO — use these numbers carefully, they're contested: Paine himself claimed

Common Sense sold around 120,000 copies within its first few months and roughly 500,000 by the end of the war — but historians studying this note that "only scant print records and no sales records survive," and Paine had every incentive to inflate his own impact. What's better-documented: the pamphlet went through about 25 print editions within its first year, and a reasonable historian's estimate is that around 20% of the colonial population owned a copy within a year of publication (in a population of roughly 3 million). On an essay, it's more defensible to say Paine's reach was "unprecedented for the era, though the exact sales figures are disputed" than to cite one specific number as fact. — Journal of the American Revolution, "Thomas Paine's Inflated Numbers"; Constitution Center, "Thomas Paine: The Original Publishing Viral Superstar".
