Pareto's later years were spent in collecting the material for his best-known work, Trattato di sociologia generale (1916) (The Mind and Society, published in 1935). 1917), published in English by Harcourt, Brace in a four-volume edition edited by Arthur Livingston under the title The Mind and Society (1935), Pareto developed the notion of the circulation of elites, the first social cycle theory in sociology. Pareto seems to have turned to sociology for an understanding of why his abstract mathematical economic theories did not work out in practice, in the belief that unforeseen or uncontrollable social factors intervened. ./cache/en-wikipedia-org-6666.html ./txt/en-wikipedia-org-6666.txt
