To be dogmatic about that which is least known would appear to be an ineradicable characteristic of human nature in its present imperfect state. “Fools rush in where angels fear to tread” is still a true saying. In the treatment of nervous disease it is amply exemplified. Where we are most ignorant, there we are most uncompromising in our dealings. When we understood absolutely nothing of insanity, seeing little connection between madness and disease, we resorted to the whip and the chain. On waking to some conception of nervous disorder, we perceive similarities more readily than differences, and proceed to lump together all diseases of the nerves in the earlier stages under the name of “hysteria.” Having already some vague foolish fixed idea in our heads about “hysteria” being synonymous with idleness and general depravity, we drag our patients about, beat them with wet towels, give them frightful shocks, galvanic or otherwise, and then get rid of them as quickly as possible, so as not to have the burden of remote consequences. But when more serious mischief is set up, what then? Why, then comes tardily a perception of differences, and we divide nervous disorders into hard and fast diseases, concluding that all had been different from the very first. The later perception of underlying similarity has as yet scarcely dawned. Some of these maladies are considered curable; others, without rhyme or reason, are considered incurable. With regard to the curability of nervous disease, let us consider what happens when we travel by train from Eastbourne to London, and again from Eastbourne to Brighton. In each case we pass through Willingdon and Polegate, and stop at Lewes. We can get out at Lewes or at either of the previous stations and return to Eastbourne, but if we proceed as far as Lewes, our return journey will be longer than if we had got out at Polegate. In the same way nervous disease is more quickly cured in the early stages than in the later stages. Now, suppose that we are in a train which does not stop between Lewes and London. It is evident in this case that, if we have missed our chance of alighting at Lewes, we must go on to the final goal; no return being possible. Thus, there is a point in certain nervous diseases beyond which recovery is impossible. On the other hand, in travelling from Eastbourne to Brighton, we have several chances of retracing our steps even after leaving Lewes, where the ways diverge; and so we find that, in some cases of nervous disease, incurability is reached sooner than in others. And just as we must be content to take longer to return from Lewes than from Polegate, so we must be content with a slow cure in advanced nervous disorders, and remember that, in administering nerve-tonics, the weaker the patient, the weaker should be the dose; all attempts to hurry the cure being fatal to success. Moreover, just as, in journeying from Eastbourne to
