or suggestions. But I feel safe in predicting that it will soon be universally acknowledged that the foundations of their theories were not laid firmly enough for permanently supporting those boldly planned structures of thought.
For a long time past I have cherished the opinion that these authors, as well as nearly all their successors and critics, are hampered by a fundamental lack of clearness as to the subject of their inquiries—a subject which they are in the habit of designating by the very indefinite name of “a society,” or, as Schäffle puts it, “the social body.” Confusion of ideas invariably proceeds from a defect of analytical reasoning; that is to say, of proper distinction.
I believe and assert that three distinct conceptions, the common object of which is social life in its broadest sense, are not sufficiently, or not at all, kept apart nor even recognized as being distinct, viz., the biological, the psychological, and the sociological in what I call the exclusive sense, the subject of this third conception only being entirely new, as compared with the subjects of other sciences or departments of philosophy. It seems to me to be our fundamental task as philosophical sociologists to deduce from this last conception, and others implied in it, a system of social structure which shall contain the different notions of collective entities in their mutual dependence and connection; and I firmly trust that out of such a system will be gained a better and more profound insight into the evolution of society at large, and into its historical phases, as the life of these collective entities. It is therefore in the struggles, first, between any of these groups and the individuals composing it; second, between their different forms and kinds—for instance, the struggles between church and empire; between church and cities; between church and state; between cities and other corporations; between the sovereign state and feudal communities, and consequently established orders or estates; between single states and a federal state—it is in these and similar struggles, presupposing the existence of those collective entities, that the growth and decay of higher civilizations exhibit themselves most markedly.
