lative part and the operative part is presently followed by a distinction, which eventually becomes very marked, between the internal arrangements of the two parts: the operative part slowly developing within itself agencies by which processes of production, distribution, and exchange are coordinated, while coordination of the non-operative part continues on its original footing.
Along with a development which renders conspicuous the separation of the operative and regulative structures, there goes a development within the regulative structures themselves. The chief, at first uniting the characters of king, judge, captain, and often priest, has his functions more and more specialized as the evolution of the society in size and complexity advances. While remaining supreme judge, he does most of his judging by deputy; while remaining nominally head of his army, the actual leading of it falls more and more into the hands of subordinate officers; while still retaining ecclesiastical supremacy, his priestly functions practically almost cease; while in theory the maker and administrator of the law, the actual making and administration lapse more and more into other hands. So that, stating the facts broadly, out of the original coordinating agent having undivided functions, there eventually develop several coordinating agencies which divide these functions among them.
Each of these agencies, too, follows the same law. Originally simple, it step by step subdivides into many parts, and becomes an organization, administrative, judicial, ecclesiastical, or military, having graduated classes within itself, and a more or less distinct form of government within itself.
I will not complicate this statement by doing more than recognizing the variations that occur in cases where supreme power does not lapse into the hands of one man (which, however, in early stages of social evolution is an unstable modification). And I must explain that the above general statements are to be taken with the qualification that differences of detail are passed over to gain brevity and clearness. Add to which that it is beside the purpose of the argument to carry the description beyond these first stages. But duly bearing in mind that, without here elaborating a Science of Sociology, nothing more than a rude outline of cardinal facts can be given, enough has been said to show that, in the development of social structures, there may be recognized certain most general facts, certain less general facts, and certain facts successively more special; just as there may be recognized general and special facts of evolution in individual organisms.
To extend, as well as to make clearer, this conception of the Social Science, let me here set down a question which comes within its sphere. What is the relation in a society between structure and growth? Up to what point is structure necessary to growth? after what point does it retard growth? at what point does it arrest growth?
