IV. MENTAL CHARACTERISTICS OF THE GREGARIOUS ANIMAL.
(_a_) Current Views in Sociology and Psychology.
If we now assume that gregariousness may be regarded as a fundamental quality of man, it remains to discuss the effects we may expect it to have produced upon the structure of his mind. It would be well, however, first, to attempt to form some idea of how far investigation has already gone in this direction. It is of course clear that no complete review of all that has been said concerning a conception so familiar can be attempted here, and, even if it were possible, it would not be a profitable enterprise, as the great bulk of writers have not seen in the idea anything to justify a fundamental examination of it. What will be done here, therefore, will be to mention a few representative writers who have dealt with the subject, and to give in a summary way the characteristic features of their exposition.
As far as I am aware, the first person to point out any of the less obvious biological significance of gregariousness was Professor Karl Pearson.[D] { 24}
[D] Many references to the subject will be found in his published works, for example in “The Grammar of Science,” in “National Life from the Standpoint of Science,” and in “The Chances of Death.” In the collection of Essays last named the essay entitled “Socialism and Natural Selection” deals most fully with the subject.
He called attention to the enlargement of the selective unit effected by the appearance of gregariousness, and to the fact that therefore within the group the action of natural selection becomes modified. This conception had, as is well known, escaped the insight of Haeckel, of Spencer, and of Huxley, and Pearson showed into what confusions in their treatment of the problems of society these three had been led by the oversight.[E] For example may be mentioned the famous antithesis of the “cosmical” and the “ethical” processes expounded in Huxley’s Romanes Lecture. It was quite definitely indicated by Pearson that the so-called ethical process, the appearance, that is to say, of altruism, is to be regarded as a directly instinctive product of gregariousness, and as natural, therefore, as any other instinct.
