The third is that the group should be brought into interaction (perhaps in the form of rivalry) with other groups similar to it but differing from it in many respects.

The fourth is that the group should possess traditions, customs and habits, and especially such as determine the relations of its members to one another.

The fifth is that the group should have a definite structure, expressed in the specialisation and differentiation of the functions of its constituents.

According to McDougall, if these conditions are fulfilled, the psychological disadvantages of the group formation are removed. The collective lowering of intellectual ability is avoided by withdrawing the performance of intellectual tasks from the group and reserving them for individual members of it.

It seems to us that the condition which McDougall designates as the 'organisation' of a group can with more justification be described in another way. The problem consists in how to procure for the group precisely those features which were characteristic of the individual and which are extinguished in him by the formation of the group. For the individual, outside the primitive group, possessed his own continuity, his self-consciousness, his traditions and customs, his own particular functions and position, and kept apart from his rivals. Owing to his entry into an 'unorganised' group he had lost this distinctiveness for a time. If we thus recognise that the aim is to equip the group with the attributes of the individual, we shall be reminded of a valuable remark of Trotter's,[20] to the effect that the tendency towards the formation of groups is biologically a continuation of the multicellular character of all the higher organisms.

IV
SUGGESTION AND LIBIDO

We started from the fundamental fact that an individual in a group is subjected through its influence to what is often a profound alteration in his mental activity. His emotions become extraordinarily intensified, while his intellectual ability becomes markedly reduced, both processes being evidently in the direction of an approximation to the other individuals in the group; and this result can only be reached by the removal of those inhibitions upon his instincts which are peculiar to each individual, and by his resigning those expressions of his inclinations which are especially his own. We have heard that these often unwelcome consequences are to some extent at least prevented by a higher 'organisation' of the group; but this does not contradict the fundamental fact of Group Psychology—the two theses as to the intensification of the emotions and the inhibition of the intellect in primitive groups. Our interest is now directed to discovering the psychological explanation of this mental change which is experienced by the individual in a group.

It is clear that rational factors (such as the intimidation of the individual which has already been mentioned, that is, the action of his instinct of self-preservation) do not cover the observable phenomena. Beyond this what we are offered as an explanation by authorities upon Sociology and Group Psychology is always the same, even though it is given various names, and that is—the magic word 'suggestion'. Tarde calls it 'imitation'; but we cannot help agreeing with a writer who protests that imitation comes under the concept of suggestion, and is in fact one of its results.[21] Le Bon traces back all the puzzling features of social phenomena to two factors: the mutual suggestion of individuals and the prestige of leaders. But prestige, again, is only recognizable by its capacity for evoking suggestion. McDougall for a moment gives us an impression that his principle of 'primitive induction of emotion' might enable us to do without the assumption of suggestion. But on further consideration we are forced to perceive that this principle says no more than the familiar assertions about 'imitation' or 'contagion', except for a decided stress upon the emotional factor. There is no doubt that something exists in us which, when we become aware of signs of an emotion in someone else, tends to make us fall into the same emotion; but how often do we not successfully oppose it, resist the emotion, and react in quite an opposite way? Why, therefore, do we invariably give way to this contagion when we are in a group? Once more we should have to say that what compels us to obey this tendency is imitation, and what induces the emotion in us is the group's suggestive influence. Moreover, quite apart from this, McDougall does not enable us to evade suggestion; we hear from him as well as from other writers that groups are distinguished by their special suggestibility.

We shall therefore be prepared for the statement that suggestion (or more correctly suggestibility) is actually an irreducible, primitive phenomenon, a fundamental fact in the mental life of man. Such, too, was the opinion of Bernheim, of whose astonishing arts I was a witness in the year 1889. But I can remember even then feeling a muffled hostility to this tyranny of suggestion. When a patient who showed himself unamenable was met with the shout: 'What are you doing? Vous vous contresuggestionnez!', I said to myself that this was an evident injustice and an act of violence. For the man certainly had a right to counter-suggestions if they were trying to subdue him with suggestions. Later on my resistance took the direction of protesting against the view that suggestion, which explained everything, was itself to be preserved from explanation. Thinking of it, I repeated the old conundrum:[22]

Christoph trug Christum,
Christus trug die ganze Welt,
Sag' wo hat Christoph
Damals hin den Fuss gestellt?[23]
