imposing will, which the group, which has no will of its own, can accept from him. Le Bon then discusses the different kinds of leaders, and the means by which they work upon the group. On the whole he believes that the leaders make themselves felt by means of the ideas in which they themselves are fanatical believers.

Moreover, he ascribes both to the ideas and to the leaders a mysterious and irresistible power, which he calls 'prestige'. Prestige is a sort of domination exercised over us by an individual, a work or an idea. It entirely paralyses our critical faculty, and fills us with astonishment and respect. It would seem to arouse a feeling like that of fascination in hypnosis (p. 148). He distinguishes between acquired or artificial and personal prestige. The former is attached to persons in virtue of their name, fortune and reputation, and to opinions, works of art, etc., in virtue of tradition. Since in every case it harks back to the past, it cannot be of much help to us in understanding this puzzling influence. Personal prestige is attached to a few people, who become leaders by means of it, and it has the effect of making everything obey them as though by the operation of some magnetic magic. All prestige, however, is also dependent upon success, and is lost in the event of failure (p. 159).

We cannot feel that Le Bon has brought the function of the leader and the importance of prestige completely into harmony with his brilliantly executed picture of the group mind.

OTHER ACCOUNTS OF COLLECTIVE MENTAL LIFE

We have made use of Le Bon's description by way of introduction, because it fits in so well with our own Psychology in the emphasis which it lays upon unconscious mental life. But we must now add that as a matter of fact none of that author's statements bring forward anything new. Everything that he says to the detriment and depreciation of the manifestations of the group mind had already been said by others before him with equal distinctness and equal hostility, and has been repeated in unison by thinkers, statesmen and writers since the earliest periods of literature.[17] The two theses which comprise the most important of Le Bon's opinions, those touching upon the collective inhibition of intellectual functioning and the heightening of affectivity in groups, had been formulated shortly before by Sighele.[18] At bottom, all that is left over as being peculiar to Le Bon are the two notions of the unconscious and of the comparison with the mental life of primitive people, and even these had naturally often been alluded to before him.

But, what is more, the description and estimate of the group mind as they have been given by Le Bon and the rest have not by any means been left undisputed. There is no doubt that all the phenomena of the group mind which have just been mentioned have been correctly observed, but it is also possible to distinguish other manifestations of the group formation, which operate in a precisely opposite sense, and from which a much higher opinion of the group mind must necessarily follow.

Le Bon himself was prepared to admit that in certain circumstances the morals of a group can be higher than those of the individuals that compose it, and that only collectivities are capable of a high degree of unselfishness and devotion. 'While with isolated individuals personal interest is almost the only motive force, with groups it is very rarely prominent.' (p. 65.) Other writers adduce the fact that it is only society which prescribes any ethical standards at all for the individual, while he as a rule fails in one way or another to come up to its high demands. Or they point out that in exceptional circumstances there may arise in communities the phenomenon of enthusiasm, which has made the most splendid group achievements possible.

As regards intellectual work it remains a fact, indeed, that great decisions in the realm of thought and momentous discoveries and solutions of problems are only possible to an individual, working in solitude. But even the group mind is capable of genius in intellectual creation, as is shown above all by language itself, as well as by folk-song, folk-lore and the like. It remains an open question, moreover, how much the individual thinker or writer owes to the stimulation of the group in which he lives, or whether he does more than perfect a mental work in which the others have had a simultaneous share.

In face of these completely contradictory accounts, it looks as though the work of Group Psychology were bound to come to an ineffectual end. But it is easy to find a more hopeful escape from the dilemma. A number of very different formations have probably been merged under the term 'group' and may require to be distinguished. The assertions of Sighele, Le Bon and the rest relate to groups of a short-lived character, which some passing interest has hastily agglomerated out of various sorts of individuals. The characteristics of revolutionary groups, and especially those of the great French Revolution, have unmistakably influenced their descriptions. The opposite opinions owe their origin to the consideration of those stable groups or associations in which mankind pass their lives, and which are embodied in the institutions of society. Groups of the first kind stand in the same sort of relation to those of the second as a high but choppy sea to a ground swell.

McDougall, in his book on The Group Mind,[19] starts out from the same contradiction that has just been mentioned, and finds a solution for it in the factor of organisation. In the simplest case, he says, the 'group' possesses no organisation at all or one scarcely deserving the name. He describes a group of this kind as a 'crowd'. But he admits that a crowd of human beings can hardly come together without possessing at all events the rudiments of an organisation, and that precisely in these simple groups many of the fundamental facts of Collective Psychology can be observed with special ease (p. 22). Before the members of a random crowd of people can constitute something in the nature of a group in the psychological sense of the word, a condition has to be fulfilled; these individuals must have something in common with one another, a common interest in an object, a similar emotional bias in some situation or other, and ('consequently', I should like to interpolate) 'some degree of reciprocal influence' (p. 23). The higher the degree of 'this mental homogeneity', the more readily do the individuals form a psychological group, and the more striking are the manifestations of a group mind.

The most remarkable and also the most important result of the formation of a group is the 'exaltation or intensification of emotion' produced in every member of it (p. 24). In McDougall's opinion men's emotions are stirred in a group to a pitch that they seldom or never attain under other conditions; and it is a pleasurable experience for those who are concerned to surrender themselves so unreservedly to their passions and thus to become merged in the group and to lose the sense of the limits of their individuality. The manner in which individuals are thus carried away by a common impulse is explained by McDougall by means of what he calls the 'principle of direct induction of emotion by way of the primitive sympathetic response' (p. 25), that is, by
