On the other hand, points out that born together, conceptually and analytically, the principle of popular sovereignty and the permanent power of constitute itself. To this is added a conceptual analogy between constituent power and democracy as far as both are relate with each other, and not only so, as both describe the collective action of self-legislation and self-change.

Only thus you rescue the radical truth of politics and modern democracy; its potential for human emancipation.
