“The Natural Law of European Peoples”: A fully commensurable system of measurement across all disciplines that tests for reciprocity in display, word (truth) and deed (action); the extension of the logic of the physical sciences (realism, naturalism, equilibration) to the psychological(individual) and social(group) sciences using economic terms (acquisition, cooperation, reciprocity); thereby completing the scientific method (falsification of all dimensions possible human cognition); and thereby completing the Aristotelian program; and thereby providing the explanation for the success of western civilization under that program: sovereignty, reciprocity, and truth – and the markets that result from their universal enforcement, and the evolutionary velocity (adaptation, innovation) that results from those markets.
