The following are related quotes:

“It is very unlikely that the general characteristics of Gibbs’ system had anything to do with Pareto’s construction of his social system. In other words it is very probable, I think nearly certain, that Pareto did not keep Gibbs’ work in mind and a fortiori that he did not imitate it, when he worked out his social system; so that Pareto’s system is not the result of the application of the theories of physical chemistry to sociology.”
— Lawrence Henderson (1935), Pareto’s General Sociology: a Physiologists Interpretation [2]
