The material collected leads us to psychological positions whose meaning goes far beyond the limits of an analysis of the narrow and concrete group of phenomena which was thus far the main subject of our study. Upon closer examination, the functional, structural, and genetic patterns disclosed in the study of factual data appear to be patterns of a more general order and compel us to revise altogether the problem of the construction and genesis of higher mental functions. Two paths lead to this review and general conclusion.
