significance—a contrast fundamentally affecting our idea of the ends to be achieved by social life.

Though the discreteness of a social organism does not prevent subdivision of functions and mutual dependence of parts, yet it does prevent that differentiation by which one part becomes an organ of feeling and thought, while other parts become insensitive. High animals, of whatever class, are distinguished from low ones by complex and well-integrated nervous systems. While in inferior types the minute scattered ganglia may be said to exist for the benefit of other structures, the concentrated ganglia in superior types are the structures for the benefit of which the rest may be said to exist. Though a developed nervous system so directs the actions of the whole body as to preserve its integrity, yet the welfare of the nervous system is the ultimate object of all these actions, damage to any other organ being serious only because it immediately or remotely entails that pain or loss of pleasure which the nervous system suffers. But the discreteness of a society negatives differentiations carried to this extreme. In an individual organism the minute living units, most of them permanently localized, growing up, working, reproducing, and dying away in their respective places, are in successive generations moulded to their respective functions, so that some become specially sentient and others entirely insentient. But it is otherwise in a social organism. The units of this, out of contact and much less rigidly held in their relative positions, cannot be so much differentiated as to become feelingless units and units which monopolize feeling. There are, indeed, slight traces of such a differentiation. Human beings are unlike in the amounts of sensation and emotion producible in them by like causes: here great callousness, here great susceptibility, is characteristic. In the same society, even where its members are of the same race, and still more where its members are of dominant and subject races, there exists a contrast of this kind. The mechanically-working and hard-living units are less sensitive than the mentally-working and more protected units. But while the regulative structures of the social organism tend, like those of the individual organism, to become seats of feeling, the tendency is checked by this want of physical cohesion which brings fixity of function; and it is also checked by the continued need for feeling in the mechanically-working units for the due discharge of their functions.

Hence, then, a cardinal difference in the two kinds of organisms. In the one, consciousness is concentrated in a small part of the aggregate. In the other, it is diffused throughout the aggregate: all the units possess the capacities for happiness and misery, if not in equal degrees, still in degrees that approximate. As, then, there is no social sensorium, it results that the welfare of the aggregate, considered apart from that of the units, is not an end to be sought. The society exists for the benefit of its members; not its members for the benefit
