Few examples could be found to illustrate better such conditions than alcoholism. Almost universally regarded as either, on the one hand, a sin or vice, or on the other hand, as a disease, there can be little doubt that in fact it is essentially a response to a psychological necessity. In the tragic conflict between what he has been taught to desire and what he is allowed to get, man has found in alcohol, as he has found in certain other drugs, a sinister but effective peacemaker, a means of securing, for however short a time, some way out of the prison house of reality back to the Golden Age. There can be equally little doubt that it is but a comparatively small proportion of the victims of conflict who find a solace in alcohol, and the prevalence of alcoholism and the punishments entailed by the use of that dreadful remedy cannot fail to impress upon us how great must be the number of those whose need was just as great, but who were too ignorant, too cowardly, or perhaps too brave to find a release there. We have seen that mental instability must be regarded as a condition extremely common, and produced by the mental conflict forced upon man by his sensitiveness to herd suggestion on the one hand and to experience on the other. It remains for us to estimate in some rough way the characteristics of the unstable, in order that we may be able to judge of their value or otherwise to the State and the species. Such an estimate must necessarily be exaggerated, over-sharp in its outlines, omitting {59} much, and therefore in many respects false. The most prominent characteristic in which the mentally unstable contrast with the “normal” is what we may vaguely call motive. They tend to be weak in energy, and especially in persistence of energy. Such weakness may translate itself into a vague scepticism as to the value of things in general, or into a definite defect of what is popularly called will power, or into many other forms, but it is always of the same fundamental significance, for it is always the result of the thwarting of the primary impulses to action resident in herd suggestion by the influence of an experience which cannot be disregarded. Such minds cannot be stimulated for long by objects adequate to normal ambition; they are apt to be sceptical in such matters as patriotism, religion, politics, social success, but the scepticism is incomplete, so that they are readily won to new causes, new religions, new quacks, and as readily fall away therefrom.
