In the nineteenth century there was an iU-founded hope that some species of political remedy for industrial ills might be discovered; this hope has passed. There have been very considerable political changes, both generally and also in particular national systems, since the end of the war in 1918. But the human problems of industrial organization remain identical for Moscow, London, Rome, Paris, and New York. As ever in human affairs, we are struggling against our own ignorance and not against the machinations of a political adversary.

The statements of academic psychology often seem to imply that logical thinking is a continuous function of the mature person — that the sufficiently normal infant develops from syncretism and non-logic to logic and skilled performance. Such a description seems to be supported by much of the work of Piaget, of Claparede, and, with respect to the primitive, by Levy-Bruhl. If one examines the facts with care, either in industry or in clinic, one finds immediately that this implication, so flattering to the civilized adult, possesses only a modicum of truth. Indeed, one may go further and say that it is positively misleading.
