From the viewpoint of carrying out multi-disciplinary studies between
economics and other social sciences, Pareto's theories are especially
important as they are the core of contemporary orthodox economics. His
sociology is constructed very differently from his economics. First the
former deals with non-rational social behaviour of human beings, whilst
the latter with rational behaviour; secondly, in the methodology the
former is empirical and inductive, while the latter is logical and
deductive. The present volume is a revamping of works by two authorities
on Pareto. It combines Alfonso de Pietri-Tonelli's address to the
Italian Association for Advancement of Science on the occasion of the
tenth anniversary of Pareto's death with selected chapters of Vilfredo
Pareto, sa vie et son oeuvre, Payot, Paris, 1928 by G.H. Bousquet.
