ABSTRACT
THE PURPOSE of this and the next chapter will be to consider the many unanswered questions raised in the preceding chapters, questions which could not be discussed adequately until all the data had been presented. It is necessary for clarity to keep separate two points of view. Any group can be regarded: (1) as a collectivity in and by itself, with certain internal functions; and (2) as a unit in a wider organization, with certain external functions. In other words, a group can be considered either from the point of view of its “internal function” or from the point of view of its “external function.” These distinctions are useful in that they allow one to confine attention to one body of data at a time and to proceed in an orderly fashion.
