Abstract
Needless to say, it is sure that all sociological theories presuppose substantially some conception of the nature of man, which fundamentally orients the development of man. So for in sociology, however, attempts to make such conception explicit has generally tended to be avoided.
But as A. Inkels indicated, for example, even Durkheim that denied any psychological explanation, could not help presupposing implicitly a kind of personality model in his practical researches.
Indeed, it is natural to say that the explication of such presuppositions was neither necessary nor appropriate in social sciences, above all in sociology of those days, for it was required to obtain its own “citizenship” as an independent special discipline. But the present circumstances are the reverse to the past.
When we think of it, we can never close our eyes to the fact that the significance of the theory of personality in modern sociology grows greater and greter in its relation to the theory of action. In this respect, it seems somewhat useful for the first being to pursue critically the development of T. Parsons' theories in order to find a clue to the model-building in this new front of sociology.
Thus it is by reason of this that his series of theories are brought to focus of the critical investigation in my present paper.
