5/17«In spite of this axiomatization (now a basic reference point for which all other social sciences should aim), within economics many problems referable to the uniqueness and global stability of equilibrium remain unsolved. But even more critical problems (perhaps including the first two) exist. They concern the semantic interpretation of the theory and are closely associated with the exclusion of the psychological and social variables by economic analysis.»
