Although Rousseau substitutes the norm of political law for that of natural law, his position cannot be assimilated to either positivism or to pure proceduralism. The norm of justice, immanent in the social contract, produces a norm external to all established order and makes assessing the justice of societies possible. If consent is legitimate only on the condition of real reciprocity, then the limits of consent lie in the fact that what is lost cannot be compensated or restituted through any (...) other form. The rights of humanity can then be defined as the inalienable rights of every individual: the rights to life and to equal freedom. This contribution will define the right of resistance which can be conceived from the rights of humanity, as well as the contesting attitudes of the established order that Rousseau conceives. (shrink)
