Topic 3.4 Notes – Philosophical Foundations of the American Revolution
How Colonists Redefined Legitimate Government
After the imperial crisis of the 1760s and 1770s, the argument got much bigger than taxes or representation. Colonists started asking a deeper question. What makes a government legitimate at all?
The Enlightenment pushed that shift. It emphasized reason, individual ability, and questioning old authority just because it was old.
- John Locke in the Second Treatise of Government argued that people have natural rights to life, liberty, and property.
- Government exists to protect rights, not just command obedience.
- Jefferson later adapted Locke’s wording in the Declaration to “Life, Liberty and the pursuit of Happiness.”
That led to the idea of the social contract.
- Government is a human creation, not something God simply hands to a king.
- Legitimate power comes from the people, which the Declaration calls “the consent of the governed.”
- This clashed directly with divine-right monarchy and hereditary privilege.
If government breaks that contract, people can resist.
- Colonists embraced the right of revolution. If a government becomes destructive of rights, people may alter or abolish it.
- The Declaration is careful here. Revolution is not for “light and transient causes.” It is justified after a “long train of abuses.”
Another key Enlightenment idea was limiting power.
- Rule of law means rulers must follow law too.
- Montesquieu argued for separated powers so no one person or group could rule arbitrarily.
A common test angle is this shift. Colonists moved from seeking redress within the empire to questioning monarchy itself.
Republicanism and Religious Ideas That Strengthened Resistance
Once colonists doubted monarchy, republicanism gave them an alternative. A republic meant government without a hereditary king, based on the people and their representatives.
Republicanism
- Civic virtue mattered. Citizens were supposed to care about the public good, not only private gain.
- Patriots stayed alert to corruption, standing armies, patronage, and concentrated power because those could destroy liberty.
- They opposed aristocracy and hereditary privilege.
- They preferred merit and talent over birth.
Still, this was not full modern democracy.
- Many Patriots accepted property qualifications and limited political participation.
- So republicanism challenged monarchy, but it did not create equal political rights for everyone.
Religion and liberty
Religious ideas often reinforced Enlightenment ideas instead of competing with them.
- The Protestant covenant tradition sounded a lot like compact theory. Both imagined authority as based on mutual obligation.
- The First Great Awakening encouraged individual conscience and skepticism toward established authority.
- Revival networks connected colonists across colonies, which helped them think beyond local identities.
- Many Patriots believed Americans were a people specially blessed with liberty.
- Some ministers framed resistance as morally justified and even providential.
Why Independence Became the Logical Conclusion
At first, many colonists wanted reconciliation. They still saw themselves as loyal British subjects.
Then events made that harder to believe.
- Lexington and Concord turned the dispute into war.
- British military actions and rejection of colonial petitions weakened loyalty to the empire.
The shift happened in three connected moves:
- Rights of British subjects became natural rights of all people.
- Criticism of Parliament and ministers became criticism of monarchy and hereditary rule.
- Resistance within the empire became a demand for an independent republic.
Colonial self-government mattered here too. Colonists had long experience with assemblies and local rule, so self-government did not feel imaginary. This political shift soon became official in the Continental Congress.

Trumbull’s Declaration of Independence
On tests, remember this. Ideas mattered because they gave meaning to the crisis, not because philosophy alone caused the Revolution.
Common Sense and the Declaration of Independence
These two documents make the revolutionary argument in different ways. Common Sense persuades ordinary people. The Declaration gives the official justification.
Common Sense
- Thomas Paine, January 1776
- A widely read pamphlet aimed at ordinary colonists
- Attacked monarchy and hereditary succession as irrational and corrupt
- Argued that “an island” should not rule “a continent”
- Rejected reconciliation after bloodshed
- Called for republican self-government, written constitutions, and independence
- Made independence seem both practical and morally necessary
Declaration of Independence
- Adopted July 4, 1776
- Principal drafter Thomas Jefferson
- Committee of Five included John Adams, Benjamin Franklin, Roger Sherman, and Robert R. Livingston
Its argument unfolds step by step:
- All men are created equal
- People have unalienable rights
- Governments exist to secure those rights
- Governments get just powers from consent
- People may alter or abolish destructive governments
- Grievances against George III prove tyranny
- The colonies are therefore free and independent states
It also had diplomatic value. It explained independence to colonists and appealed to foreign powers.
What Changed and Why It Matters
Colonists shifted from loyalty to the British constitution toward popular sovereignty and republican independence. Authority now flowed upward from the people, not downward from a king.
Enduring ideals from this moment:
- liberty
- equality
- natural rights
- consent of the governed
- right of revolution
- republican government
There was a huge contradiction. Revolutionary language was universal, but rights were not applied equally to women, enslaved people, American Indians, and many propertyless men. Jefferson himself enslaved people.
That contradiction is why these documents lasted. Later reformers kept using their language to demand that the nation live up to its own ideals.
