“Each of us puts his person and all his power in common under the supreme direction of the general will, and, in our corporate capacity, we receive each member as an indivisible part of the whole.”Jean-Jacques Rousseau · Contractul social · 1762 · Cartea I, capitolul 6
You surrender freedom not to a master, but to everyone — to yourself as citizen.
Here lies the core of the book: people do not surrender their rights to a master but to everyone, that is, to themselves as a political body. Each obeys a will to which he himself contributes, so he remains free, though free differently: as a citizen, not as an isolated individual. The formula an indivisible part shows that no one can be removed from the agreement without destroying it. Example: a community deciding through rules that everyone helped to make.
Why it matters It describes the condition of a healthy democracy: laws we can regard as our own rather than as foreign impositions.
