Of course, if those who occupy these positions of prestige feel no responsibility of this sort and make no effort to exert such influence, but rather aim at striking terror in the foe at all costs, if they countenance acts of savagery such as the destruction of cities, looting, and rapine, if they publicly instruct their soldiers to behave as Huns or savages; then the organisation of the army works in the opposite way—namely, to degrade all members below their normal individual level, rather than to raise them above it; and then we hear of acts of brutality on the part of the rank and file which are almost incredible.
But the main point to be insisted on here is that the raising of the moral level is not effected only by example, suggestion, and emotional contagion, spreading from those in the positions of prestige; that, where the group spirit exists, those enjoying prestige can, if they wish, greatly promote the end of raising the moral tone of the whole by appealing to that group spirit; as when Lord Kitchener asked the men to obey his injunctions for the sake of the honour of the British Army.
And the group spirit not only yields this direct response to moral exhortation; it operates in another no less important manner. Each member of a group pervaded by the collective sentiment, such as a well-organised army of high traditions, becomes in a special sense his brother’s keeper. Each feels an interest in the conduct of every other member, because the conduct of each affects the reputation of the whole; each man, therefore, punishes bad conduct of any fellow soldier by scorn and by withdrawal of sympathy and companionship; and each one rewards with praise and admiration the conduct that conforms to the standards demanded and admired. And so each member acts always under the jealous eyes of all his fellows, under the threat of general disapprobation, contempt, and moral isolation for bad conduct; under the promise of general approval and admiration for any act of special excellence.
The development of the group spirit, with the appropriate sentiment of attachment or devotion to the whole and therefore also to its parts, is the essence of the higher form of military discipline. There is a lower form of discipline which aims only at rendering each man perfectly subservient to his officers and trained to respond promptly and invariably, in precise, semi-mechanical, habitual fashion, to every word of command. But even the drill and the system of penalties and minute supervision, which are the means chosen to bring about this result, cannot fail to achieve certain effects on a higher moral and intellectual level than the mere formation of bodily habits of response. By rendering each soldier apt and exact in his response to commands, they enable each one to foresee the actions of his fellows in all ordinary circumstances, and therefore to rely upon that co-operation towards the common end, be it merely a turning movement on the drill ground or the winning of a battle, which is the essential aim and justification of all group life.
The group spirit, involving knowledge of the group as such, some idea of the group, and some sentiment of devotion or attachment to the group, is then the essential condition of all developed collective life, and of all effective collective action; but it is by no means confined to highly developed human associations of a voluntary kind.
Whether the group spirit is possessed in any degree by animal societies is a very difficult question. We certainly do not need to postulate it in order to account for the existence of more or less enduring associations of animals; just as we do not need to postulate it to account for the coming together of any fortuitous human mob. Even in such animal societies as those of the ants and bees, its presence, though often asserted, seems to be highly questionable. When we observe the division of labour that characterises the hive, how some bees ventilate, some build the comb, some feed the larvae and so on; and especially when we hear that the departure of a swarm from the hive is preceded by the explorations of a small number which seek a suitable place for the new home of the swarm and then guide it to the chosen spot, it seems difficult to deny that some idea of the community and its needs is present to the minds of its members. But we know so little as yet of the limits of purely instinctive behaviour (and by that I mean immediate reactions upon sense-perceptions determined by the innate constitution) that it would be rash to make any such inference. The same may be said of associations of birds or mammals, in which division of labour is frequently displayed; when, for example, it is found that one or more sentinels constantly keep watch while a flock or herd feeds or rests, as is reported of many gregarious species.
But, however it may be with animal societies, we may confidently assert that the group spirit has played an important part in the lives of all enduring human groups, from the most primitive ages onwards.
It has even been maintained with some plausibility that group self-consciousness preceded individual self-consciousness in the course of the evolution of the human mind. That again is, it seems to me, a proposition which cannot be substantiated. But it is, I think, true to say that the two kinds of self-consciousness must have been achieved by parallel processes, which constantly reacted upon one another in reciprocal promotion.
In the lives of the humblest savages the group spirit plays an immensely important part. It is the rule that a savage is born into a small closed community. Such a community generally has its own locality within which it remains, even if nomadic; and, if settled, it wholly lives in a village, widely separated in space from all others. In this small community the child grows up, becoming more or less intimately acquainted with every member of it, and having practically no intercourse with any other persons. Throughout his childhood he learns its laws and traditions, becomes acutely aware of its public opinion, and finds his welfare absolutely bound up with that of the village community. He cannot leave it if he would; the only alternative open to him is to become an outcast, as which he would very soon succumb in the struggle for life. There is nothing comparable with this in our complex civilised societies. The nearest parallel to it is the case of the young child growing up in a peculiarly secluded family isolated in the depths of the country.
