There is, however, one condition that may raise the behaviour of a temporary and unorganised crowd to a higher plane, namely the presence of a clearly defined common purpose in the minds of all its members. Such a crowd, for example a crowd of white men in one of the Southern States of North America setting out to lynch a negro who is supposed to have committed some flagrant crime, will display most of the characteristics of the common crowd, the violence and brutality of emotion and impulse, the lack of restraint, the diminished sense of responsibility, the increased suggestibility and incapacity for arriving at correct conclusions by deliberation and the weighing of evidence. But it will not exhibit the fickleness of a common crowd, the easy yielding to distracting impressions and to suggestions that are opposed to the common purpose. Such a crowd may seize and execute its victim with inflexible determination, perhaps with a brutality and a ruthless disregard of all deterrent considerations of which no one of its members would be individually capable; and may then at once break up, each man returning quietly and seriously to his home, in a way which has often been described by witnesses astonished at the contrast between the behaviour of the crowd and that of the individuals into which it suddenly resolves itself. The behaviour of a crowd of this kind raises the problem of the general or collective will. It was said in the foregoing chapter that the actions of a common crowd cannot properly be regarded as volitional, because they are the immediate outcome of the primary impulses. Yet the actions of a crowd of the kind we are now considering are the issue of true resolutions formed by each member of the crowd, and are, therefore, truly volitional. Nevertheless, they are the expression not of a general or collective will, but merely of the wills of all the individuals; and, even if there arise differences between the members and a conflict of wills as to the mode of achieving the common end, and if the issue be determined simply by the stronger party overbearing the weaker and securing their co-operation, that still does not constitute the expression of a general will. For a collective or general will only exists where some idea of the whole group and some sentiment for it as such exists in the minds of the persons composing it. But we may with advantage examine the nature of collective volition on a later page, in relation to the life of a highly organised group, such as an army.
