The Social and Statistical Equilibrium of Aggregates

In 1994, Michio Morishima made the point that, on passing from economic equilibrium to social equilibrium (i.e. from individuals to aggregates), Pareto’s thought came closer to the concept of equilibrium in statistical physics (1994, p. xi). As we said, this could only hold if society were seen as a single, huge aggregate. The picture changes when we begin to consider many sublevels of organization (i.e. many groups), and Morishima added: “So it is not an easy thing to achieve a harmonious coexistence between these different equilibria” (ibid.). This is true not only when we consider economic and statistical equilibria, but also when we look at statistical and social equilibria.

For a start, as well as economic differences, the political circulation of élites is a necessary condition for heterogeneity, and also a consequence of it. Pareto followed the same path as in his analysis on the distribution of income: a political élite exists, and it includes only a small proportion of the population. The exercise of power, which no society can do without, relies on heterogeneity; and, when it comes to power, heterogeneity generates a hierarchy:Human societies cannot subsist without a hierarchy; but it would be a very grave mistake to conclude from this that they will be the more prosperous the more rigid is this hierarchy. (1906, chap. VII, sec. 103)
