Leaving this aspect of the subject for a time, let us look more closely at the process of conversion. It has already been pointed out that one great feature of adolescence is susceptibility to impressions and suggestions. One is not surprised to find, therefore, that in Starbuck's collection of cases 34 per cent. of the females and 29 per cent. of the males described their conversion as being directly due to imitation, social pressure, and example. If we were to add to these the cases where unconscious imitation and suggestion is at work, the proportion would be much greater. Religion, like dress, has its modes, and imitation will occur in the one direction as readily as in the other. Nothing is more striking in the records of conversion than the monotony of the language used to describe the feelings experienced. It is exactly as though the converts had been learning a regular catechism, as in a way they have been. Young boys and girls will confess their sinful state in language identical with that used by one who has actually lived a career of vice and crime. Others of an aggressively commonplace character will use the language of exalted mysticism suitable to an Augustine or a Jacob Boehme. In these cases we have not identity of feeling finding expression in identity of language; it is pure imitation and suggestion without the least regard to the fitness of the language employed. The full power of suggestion would be more fitly considered in connection with waves of religious feeling that have assumed an epidemic form; but it will not be out of place here to call attention to this factor in such a recent case as the outbreaks in Wales under the leadership of persons such as Evan Roberts. Quite apart from the suggestion and imitation operating in the gatherings themselves, it is plain that many went to the meetings quite prepared to act in accordance with what had gone before. Newspapers had published elaborate reports of the 'scenes,' certain manifestations were recognised as signs of the "workings of the Spirit," with the result that all these operated as powerful suggestions, particularly with those of a hysterical disposition. And behind this particular revival there were the traditions of other revivals, all of which had created a heritage as coercive as any purely social tradition. A crowd of people in a state of eager expectancy, exposed to the assaults of a preacher skilled in rousing their emotion to fever pitch, is naturally ready to see and hear things that none would see and hear in their normal moments. No better field for the study of crowd psychology, particularly at the point at which it merges into the abnormal, could be imagined than the ordinary revival.
