ABSTRACT
In studying the genus of residues Vilfredo Pareto proceeds to make a merciless and interesting analysis of egalitarian demands, whose hypocrisy he is eager to unmask. The study of derivations in the Treatise on Sociology has several aspects. One may examine verbal manifestations in terms of logic and show if, when, and how men's various verbal manifestations deviate from logic. If paternal authority does not suffice, the mother resorts to a third class of derivations, illustrated by the Bogyman or Santa Claus, depending on whether it is a negative or a positive act. The different classes of residues correspond to groups of sentiments that act in all societies and throughout history. The most important proposition regarding residues, in Pareto, is that the classes of residues vary little, which means that man, as defined by the classes of residues, does not fundamentally change.
