A treatise on this concept, which argues that laws are not legitimate unless they follow the “general will,” opens “Man is born free, and everywhere he is in (10[1])chains.” For 10 points, name this concept coined in a Jean-Jacques Rousseau book that envisions communities as agreeing to certain rights and responsibilities. ■END■ (10[1])
