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.
