Pareto’s treatment of the circulation of elites is often cited and is generally considered the most interesting part of his sociology. Pareto believed that individuals are born with quite different abilities and acquire quite different skills and aptitudes.
According to Pareto, since in every society there are classes, therefore each society is heterogeneous. Such a heterogeneity takes place on account of mental, moral, physical and cultural reasons but helps in maintaining social balance and organisation. According to Pareto, people are unequal physically, as well as intellectually and morally.
