“Those who consider themselves the masters of others are indeed greater slaves than they.”Jean-Jacques Rousseau · Contractul social · 1762 · Cartea I, capitolul 1
Ruling others is not power, but slavery with extra masters to serve.
Rousseau inverts the apparent hierarchy: ruling others is not power but dependence. Whoever holds power over others needs them to keep his position, lives in fear of losing it, and is caught in the intrigues of the court. A tyrant does not sleep soundly; a free man, with power over no one, does. The sentence prepares the idea that the only legitimate mastery is over one's own life.
Why it matters A healthy perspective for anyone climbing the hierarchy and discovering that power brings servitude along with perks.
