I will begin by drawing attention to the practical side of two of the channels for self-expression, which are specially insisted upon in schools where the new mode is being practised, namely, dancing and drawing. A friend of mine always refers to them as the two D’s, a phrase that refers very explicitly to these two forms of damnation when employed as fundamentals in education. The method of the “Free Expressionists” is to associate music with the first of these arts. Now music and dancing are, as every one knows, excitements which make a stronger emotional appeal to the primitive than to the more highly evolved races. No drunken man in our civilisation ever reaches the stage of anæsthesia and complete loss of self-control attained by the savage under the influence of these two stimuli. But in the schools where I have witnessed children’s performances, I have seen the first beginnings of that madness which is the savage’s ecstasy. Music in this connection is an artificial stimulus and a very potent one. And though artificial stimuli may be permissible in certain forms of pleasure sought by the reasoning, trained adult, they are uncommonly dangerous incitements to use in the education of a child of six. Need I defend still further my description of music as an artificial and powerful stimulus? During the present war it has been reported that the influence of alcohol and drugs has been resorted to by the Germans to drive their men to the attack. But we know that in earlier wars, the greatest effects could be attained by music, effects that drive the fighters into the most delirious excesses of savagery. And, doubtless, if the sound of music could have made itself heard above the awful din of guns that precede a modern advance, the old stimulus would have been preferred by the Germans to the administration of drugs. As it is, I have heard that bands are used whenever possible. Full-grown men and women will admit that they can become “drunk” with music and by “drunk” I mean that the motions of the subconsciousness are excited to such a pitch that they take control, until they completely dominate the reasoning faculties. Alcohol produces this result by partial paralysis of the peripheral cilia, music and dancing by overexaltation of the whole kinæsthetic system. In the latter case, however, no evil effects can be produced in the first instance, without the reasoning consent or submission of the subject. Savages and _young children have not yet learnt to withhold that consent_.
