We cannot for long enjoy the illusion that we have solved the riddle of the group with this formula. It is impossible to escape the immediate and disturbing recollection that all we have really done has been to shift the question on to the riddle of hypnosis, about which so many points have yet to be cleared up. And now another objection shows us our further path.

It might be said that the intense emotional ties which we observe in groups are quite sufficient to explain one of their characteristics--the lack of independence and initiative in their members, the similarity in the reactions of all of them, their reduction, so to speak, to the level of group individuals. But if we look at it as a whole, a group shows us more than this. Some of its features--the weakness of intellectual ability, the lack of emotional restraint, the incapacity for moderation and delay, the inclination to exceed every limit in the expression of emotion and to work it off completely in the form of action--these and similar features, which we find so impressively described in Le Bon, show an unmistakable picture of a regression of mental activity to an earlier stage such as we are not surprised to find among savages or children. A regression of this sort is in particular an essential characteristic of common groups, while, as we have heard, in organized and artificial groups it can to a large extent be checked.

We thus have an impression of a state in which an individual's separate emotion and personal intellectual act are too weak to come to anything by themselves and are absolutely obliged to wait till they are reinforced through being repeated in a similar way in the other members of the group. We are reminded of how many of these phenomena of dependence are part of the normal constitution of human society, of how little originality and personal courage are to be found in it, of how much every individual is ruled by those attitudes of the group mind which exhibit themselves in such forms as racial characteristics, class prejudices, public opinion, etc. The influence of suggestion becomes a greater riddle for us when we admit that it is not exercised only by the leader, but by every individual upon every other individual; and we must reproach ourselves with having unfairly emphasized the relation to the leader and with having kept the other factor of mutual suggestion too much in the background.

After this encouragement to modesty, we shall be inclined to listen to another voice, which promises us an explanation based upon simpler grounds. Such a one is to be found in Trotter's thoughtful book upon the herd instinct, concerning which my only regret is that it does not entirely escape the antipathies that were set loose by the recent great war.[50]

Trotter derives the mental phenomena that are described as occurring in groups from a herd instinct ('gregariousness'), which is innate in human beings just as in other species of animals. Biologically this gregariousness is an analogy to multicellularity and as it were a continuation of it. From the standpoint of the libido theory it is a further manifestation of the inclination, which proceeds from the libido, and which is felt by all living beings of the same kind, to combine in more and more comprehensive units.[51] The individual feels 'incomplete' if he is alone. The dread shown by small children would seem already to be an expression of this herd instinct. Opposition to the herd is as good as separation from it, and is therefore anxiously avoided. But the herd turns away from anything that is new or unusual. The herd instinct would appear to be something primary, something 'which cannot be split up'.

Trotter gives as the list of instincts which he considers as primary those of self-preservation, of nutrition, of sex, and of the herd. The last often comes into opposition with the others. The feelings of guilt and of duty are the peculiar possessions of a gregarious animal. Trotter also derives from the herd instinct the repressive forces which psycho-analysis has shown to exist in the ego, and from the same source accordingly the resistances which the physician comes up against in psycho-analytic treatment. Speech owes its importance to its aptitude for mutual understanding in the herd, and upon it the identification of the individuals with one another largely rests.

While Le Bon is principally concerned with typical transient group formations, and McDougall with stable associations, Trotter has chosen as the centre of his interest the most generalised form of assemblage in which man, that Ϛὡον πολιτικὁν, passes his life, and he gives us its psychological basis. But Trotter is under no necessity of tracing back the herd instinct, for he characterizes it as primary and not further reducible. Boris Sidis's attempt, to which he refers, at tracing the herd instinct back to suggestibility is fortunately superfluous as far as he is concerned; it is an explanation of a familiar and unsatisfactory type, and the converse proposition--that suggestibility is a derivative of the herd instinct--would seem to me to throw far more light on the subject.

But Trotter's exposition, with even more justice than the others', is open to the objection that it takes too little account of the leader's part in a group, while we incline rather to the opposite judgement, that it is impossible to grasp the nature of a group if the leader is disregarded. The herd instinct leaves no room at all for the leader; he is merely thrown in along with the herd, almost by chance; it follows, too, that no path leads from this instinct to the need for a God; the herd is without a herdsman. But besides this Trotter's exposition can be undermined psychologically; that is to say, it can be made at all events probable that the herd instinct is not irreducible, that it is not primary in the same sense as the instinct of self-preservation and the sexual instinct.

It is naturally no easy matter to trace the ontogenesis of the herd instinct. The dread which is shown by small children when they are left alone, and which Trotter claims as being already a manifestation of the instinct, nevertheless suggests more readily another interpretation. The dread relates to the child's mother, and later to other familiar persons, and it is the expression of an unfulfilled desire, which the child does not yet know how to deal with in any way except by turning it into dread.[52] Nor is the child's dread when it is alone pacified by the sight of any haphazard 'member of the herd', but on the contrary it is only brought into existence by the approach of a 'stranger' of this sort. Then for a long time nothing in the nature of herd instinct or group feeling is to be observed in children. Something like it grows up first of all, in a nursery containing many children, out of the children's relation to their parents, and it does so as a reaction to the initial envy with which the elder child receives the younger one. The elder child would certainly like to put its successor jealously aside, to keep it away from the parents, and to rob it of all its privileges; but in face of the fact that this child (like all that come later) is loved by the parents in just the same way, and in consequence of the impossibility of maintaining its hostile attitude without damaging itself, it is forced into identifying itself with the other children. So there grows up in the troop of children a communal or group feeling, which is then further developed at school. The first demand made by this reaction-formation is for justice, for equal treatment for all. We all know how loudly and implacably this claim is put forward at school. If one cannot be the favourite oneself, at all events nobody else shall be the favourite. This transformation--the replacing of jealousy by a group feeling in the nursery and classroom--might be considered improbable, if the same process could not later on be observed again in other circumstances. We have only to think of the troop of women and girls, all of them in love in an enthusiastically sentimental way, who crowd round a singer or pianist after his performance. It would certainly be easy for each of them to be jealous of the rest; but, in face of their numbers and the consequent impossibility of their reaching the aim of their love, they renounce it, and, instead of pulling out one another's hair, they act as a united group, do homage to the hero of the occasion with their common actions, and would probably be glad to have a share of his flowing locks. Originally rivals, they have succeeded in identifying themselves with one another by means of a similar love for the same object. When, as is usual, a situation in the field of the instincts is capable of various outcomes, we need not be surprised if the actual outcome is one which involves the possibility of a certain amount of satisfaction, while another, even though in itself more obvious, is passed over because the circumstances of life prevent its attaining this aim.

What appears later on in society in the shape of Gemeingeist, esprit de corps, 'group spirit', etc., does not belie its derivation from what was originally envy. No one must want to put himself forward, every one must be the same and have the same. Social justice means that we deny ourselves many things so that others may have to do without them as well, or, what is the same thing, may not be able to ask for them. This demand for equality is the root of social conscience and the sense of duty. It reveals itself unexpectedly in the syphilitic's dread of infecting other people, which psycho-analysis has taught us to understand. The dread exhibited by these poor wretches corresponds to their violent struggles against the unconscious wish to spread their infection on to other people; for why should they alone be infected and cut off from so much? why not other people as well? And the same germ is to be found in the pretty anecdote of the judgement of Solomon. If one woman's child is dead, the other shall not have a live one either. The bereaved woman is recognized by this wish.

Thus social feeling is based upon the reversal of what was first a hostile feeling into a positively-toned tie of the nature of an identification. So far as we have hitherto been able to follow the course of events, this reversal appears to be effected under the influence of a common tender tie with a person outside the group. We do not ourselves regard our analysis of identification as exhaustive, but it is enough for our present purpose that we should revert to this one feature--its demand that equalization shall be consistently carried through. We have already heard in the discussion of the two artificial groups, church and army, that their preliminary condition is that all their members should be loved in the same way by one person, the leader. Do not let us forget, however, that the demand for equality in a group applies only to its members and not to the leader. All the members must be equal to one another, but they all want to be ruled by one person. Many equals, who can identify themselves with one another, and a single person superior to them all--that is the situation that we find realised in groups which are capable of subsisting. Let us venture, then, to correct Trotter's pronouncement that man is a herd animal and assert that he is rather a horde animal, an individual creature in a horde led by a chief.
