Miranda proposed non-mainstream ideas that challenged both the power structures and the two antagonistic new philosophical schools—Rousseau on the left and Bentham on the right. A definition of a Precursor and a proposition for an objective criterion to measure the degree of the forwardness of his political thinking are set. The Precursor’s accuracy is objectively measurable anyway through the degree of forecast of observable posterior regimes, whether they were assessed subjectively as “good or bad”. It shows that Miranda was a true revolutionary precursor, announcing the results of the historical natural selection between political ideas/regimes that have progressively been selected as democratic governance and regional integration. Miranda’s democratic principles rely on transposing the scientific method to the area of governance progress, substituting radical political ideologies for warranting pluralist debates able to form consensus on society’s choices. This innovation represents a significant advancement in political thought. This chapter explains how Miranda institutionally structured his proposals based on strict separation of powers, which requires rejecting the Jacobin “popular power” in an original synthesis between Anglo-Saxon, French, and Indigenous cultures, providing the first non-Euro-centric proposal, obviously rejected by oligarchies and mainly ignored by historians.
