Thomas Paine's Core Argument in 'Common Sense'

In Common Sense (1776), Thomas Paine argues that the American colonies must declare independence from Great Britain. His argument rests on three pillars:

1. Natural Rights & Government's Purpose

Every individual possesses inherent rights to life, liberty, and property. Government’s sole legitimate function is to secure these rights. The British monarchy systematically violated them through taxation without representation, quartering troops, and denying trial by jury.

2. Capacity for Self-Governance

Colonists are not dependent children; they have proven capable of self-rule through colonial assemblies, commerce, and militia. Paine cites successful republics (e.g., Netherlands, Switzerland) to refute the claim that monarchy is necessary for order.

3. Economic Advantage

Independence would free American trade from British Navigation Acts, opening global markets. The continent’s resources and population could sustain a thriving economy without imperial extraction.

Rhetorical Power

Paine wrote in plain, forceful language for a broad audience, not elite philosophers. This accessibility turned abstract Enlightenment principles into a mass mobilization tool, shifting public opinion decisively toward independence within months.
