The Geneva Manuscript: Rousseau's First Draft

Before the Social Contract became the book we know, there was a rough draft. Rousseau wrote it, crossed things out, reworked arguments, and left it in a pile of papers. It was found after his death in Geneva, so scholars call it the Geneva Manuscript. Think of it as version 0.9 of his political philosophy.

What makes it interesting is that it contains a whole chapter Rousseau cut from the final version. Book I, Chapter 2: “Of the General Society of the Human Race.” This chapter is a direct argument with his friend Denis Diderot. And it reveals how Rousseau arrived at his core ideas.

The Debate with Diderot

In 1755, Diderot published an article called “Natural Right” in the Encyclopedie. He imagined a skeptic who understands justice but sees no reason to follow it. Why be moral if nobody is making you? Diderot’s answer: such a person is simply unreasonable. There exists a “general will of the human race” that tells us what is right. Just look into your heart and you will find it.

Rousseau read this and basically said: that is a nice idea, Denis, but it does not work.

Why a “Natural” General Society Fails

Rousseau’s argument is blunt. There is no natural universal society of humanity. Yes, people need each other. As our desires grow beyond what we can satisfy alone, we reach out to others. But needing someone and caring about them are two very different things.

Rousseau says our mutual dependence actually makes things worse. “The same causes which make us wicked make us also slaves.” We need each other, but we also compete with each other. Our shared humanity does not create solidarity. It creates jealousy, rivalry, and exploitation. The weak get crushed, the strong get stronger, and the so-called unity of mankind is a “deceptive unity” that produces misery.

Without real political institutions, you cannot have real moral obligations. A vague feeling of brotherhood is not enough.

The Problem of Enforcement

Rousseau then puts a very specific question to Diderot’s position. Suppose you tell the skeptic he should follow the general will. The skeptic replies: “Fine, I see the rule. But why should I obey it? Show me what interest I have in being just.”

This is not just stubbornness. It is a real problem. Diderot says the general will is a “pure act of comprehension” where you silence your passions and ask what people can fairly demand of each other. Rousseau asks: who can actually do that? Who can separate themselves from their own interests so completely?

The skeptic’s strongest point is about guarantees. “Either give me guarantees against every unjust action or do not hope that I in turn shall abstain from such.” I will play fair when everyone else is playing fair too. Without enforcement, cooperation is just hoping for the best. Rousseau points out that this is exactly how sovereign states already behave. Nations do not follow moral rules toward other nations unless forced. Why would individuals be any different?

You Need Real Communities

Here is where Rousseau lands. The general will only works inside an actual political community with real laws, real enforcement, and real shared interests. You cannot start with “the general will of all humanity” because there is no institution behind it. No mechanism to define it. No power to enforce it.

He has a great line about cosmopolitans: “Those supposed Cosmopolitans who, justifying their love for the fatherland by their love for mankind, boast of loving everyone in order to have the right to love no one.”

We become moral beings through our particular communities, not through abstract principles. “We begin truly to become men only after having been Citizens.”

What Changed in the Final Version

Rousseau cut this entire chapter from the published Social Contract. Probably because it was too negative, too focused on what does not work. The final version starts more directly: here is the problem, here is the solution. No chapter demolishing Diderot first.

But the ideas survived. The general will requires a bounded political community. Abstract universalism is not enough. Morality needs institutional structure. All of that made it into the final text. Rousseau just removed the scaffolding and presented the finished building.

The manuscript ends on a hopeful note. Even the worst skeptic can be brought around. Show him a well-ordered society where virtue is rewarded and crime punished. “This enemy of mankind will finally abjure his hatred along with his errors.” The fierce brigand can become the strongest defender of a just society. That is the entire project of the Social Contract in one sentence. And here, in this rough draft, you can see Rousseau figuring it out.
