Voltaire, Rousseau, and the Enlightenment

Why this matters

Two Enlightenment thinkers aimed at the same target, a government's real source of authority, and reached it by different roads. Voltaire fought for reason, free speech, and tolerance against church power, while Rousseau argued for popular sovereignty and the general will, and both fed directly into revolutions on two continents.

Studying two thinkers side by side teaches more than studying one alone, which is what makes this reading useful past the unit test. I'd rather students see that Enlightenment ideas were not a single fixed philosophy handed down from above, but an argument worked out between people who agreed on the target and disagreed on nearly everything about how to reach it.

From one teacher to another

This one is built around a single question I want students carrying out of the room: where does a legitimate government actually get its power. The guided notes set up Voltaire's fights for reason, free speech, and religious tolerance next to Rousseau's arguments for popular sovereignty and the general will, so students see two different Enlightenment thinkers aimed at the same target from different angles. The primary source is the real opening of Rousseau's The Social Contract - "Man is born free, and everywhere he is in chains" - and students have to pull his actual argument out of the text: that force alone creates no right, and that only agreement can. The activity closes with a verdict, using Rousseau's own words plus their notes, on where a government's authority really comes from. Guided notes, activity, quiz, and exit ticket all come with answer keys, along with a teacher guide.
