In other words, the social organism, as Spencer sees it, exists not for itself but for the benefit of the separate organs of which it is composed, whereas, in the case of biological organism the situation is reversed. There the parts manifestly exist for the whole and not the whole for the parts.
Spencer explains this paradoxical conclusion by the reflection that in social organisms sentience is not localized as it is in biological organisms. This is, in fact, the cardinal difference between the two. There is no social sensorium.
In the one (the individual), consciousness is concentrated in a small part of the aggregate. In the other (society), 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, 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 of the society.[31]
The point is that society, as distinct from the individuals who compose it, has no apparatus for feeling pain or pleasure. There are no social sensations. Perceptions and mental imagery are individual and not social phenomena. Society lives, so to speak, only in its separate organs or members, and each of these organs has its own brain and organ of control which gives it, among other things, the power of independent locomotion. This is what is meant when society is described as a collectivity.
VI. SOCIAL CONTROL AND SCHOOLS OF THOUGHT
The fundamental problem which Spencer's paradox raises is that of social control. How does a mere collection of individuals succeed in acting in a corporate and consistent way? How in the case of specific types of social group, for example an animal herd, a boys' gang, or a political party, does the group control its individual members; the whole dominate the parts? What are the specific sociological differences between plant and animal communities and human society? What kind of differences are sociological differences, and what do we mean in general by the expression "sociological" anyway?
Since Spencer's essay on the social organism was published in 1860,[32] this problem and these questions, in one form or another, have largely absorbed the theoretical interest of students of society. The attempts to answer them may be said to have created the existing schools into which sociologists are divided.
A certain school of writers, among them Paul Lilienfeld, Auguste Schäffle, and René Worms, have sought to maintain, to extend, or modify the biological analogy first advanced by Spencer. In doing so they have succeeded sometimes in restating the problem but have not solved it. René Worms has been particularly ingenious in discovering identities and carrying out the parallelism between the social and the biological organizations. As a result he has reached the conclusion that, as between a social and a biological organism, there is no difference of kind but only one of degree. Spencer, who could not find a "social sensorium," said that society was conscious only in the individuals who composed it. Worms, on the other hand, declares that we must assume the existence of a social consciousness, even without a sensorium, because we see everywhere the evidence of its existence.
Force manifests itself by its effects. If there are certain phenomena that we can only make intelligible, provided we regard them as the products of collective social consciousness, then we are bound to assume the existence of such a consciousness. There are many illustrations ... the attitude for example, of a crowd in the presence of a crime. Here the sentiment of indignation is unanimous. A murderer, if taken in the act, will get summary justice from the ordinary crowd. That method of rendering justice, "lynch law," is deplorable, but it illustrates the intensity of the sentiment which, at the moment, takes possession of the social consciousness.
Thus, always in the presence of great and common danger the collective consciousness of society is awakened; for example France of the Valois after the Treaty of Troyes, or modern France before the invasion of 1791 and before the German invasion in 1870; or Germany, herself, after the victories of Napoleon I. This sentiment of national unity, born of resistance to the stranger, goes so far that a large proportion of the members of society do not hesitate to give their lives for the safety and glory of the state, at such a moment the individual comprehends that he is only a small part of a large whole and that he belongs to the collectivity of which he is a member. The proof that he is entirely penetrated by the social consciousness is the fact that in order to maintain its existence he is willing to sacrifice his own.[33]
