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. III 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.
