The types which we have just been considering show more than a cross-sectional picture of the adult personality. They have made the transition from itemizing the instantaneous pictures to the selection of features of the immediate picture which show how the type has come to be. They are thus more than co-relational types; they have made some progress toward developmental types. When Giese found the group of political personalities of humble origin and persistent organizing and agitating activity, he postulated a common dynamic of development, a homogeneous functional disposition toward this sort of thing. Moore wanted to extricate the formative influence of temperamental reactive sets, and the other investigators have likewise sought to ascertain developmental factors in the production of the adult picture of traits and interests. Almost every nuclear and co-relational type carries developmental implications. The terms which are used to characterize motives have dynamic, genetic, formative coronas of meaning which, vaguely though they may be sketched, are emphatically present. When Michels says that a “Catonian strength of conviction” is one mark of the political leader, it is implied that if one pushed his inquiry into the adolescence, childhood, and even infancy of the individual that this ruling characteristic would be visible. Of course, Michels does not himself develop these implications; it is doubtful if he has tried to find the early analogues of the trait which he called “Cantonian strength of conviction” on the adult level. But the dynamic penumbra of the term can lead empirical investigators to scrutinize the behavior of children from a new point of view. Many of the terms which are used to describe adult traits are no doubt unpredictable from the less differentiated traits of infancy, childhood, and youth. But the growth of full-blown developmental types requires the sifting and refinement of terms until they are adequate to the description of sequences of growth. Developmental types will describe a set of terminal, adult reactions, and relate them to those critical experiences in the antecedent life of the individual which dispose him to set up such a mode of dealing with the world. Developmental types will not only include the subjective account of the history of the personality but will embrace the objective factors which were co-operating to produce the patterns described. The notion of a developmental type may be illustrated by examining the place which is assigned to the political man in the chief modern characterological systems. Hans Apfelbach has used five dimensions for the description of characters. Each one is described as a gamut between two polar opposites, and a sixth pair of polar opposites is introduced into the system. The scheme is indicated in Table II.
