Insight into human symbolic behavior and into human interaction through symbolic mechanisms comes from all sorts of disciplines: not only from linguistics, philosophy, psychology, and cultural anthropology, but from attitude research and public opinion study, from new techniques in psychotherapy, from physiology and neurology, from mathematical biology and cybernetics. How are all these separate insights to be brought together? ...I have examined the problem long enough to believe that it cannot be done without some set of broad and informing principles such as is to be found in the General Semantics of Alfred Korzybski.
