Medical men assume that self-preservation is a primal instinct, and that the person who deliberately sets out to maim himself or to destroy his life is insane, even although intellectually he may appear to be quite sound. If a man become possessed by religious zeal and set out to convert his neighbours to his views, he may incidentally be a considerable nuisance to them. He may stand at street corners and annoy the surrounding inhabitants by his exhortation; but, in Glasgow at any rate, they put up with this on account of the good intention they ascribe to him. If, however, he gives up his business, and prevents other people from attending to theirs by calling on them and arguing with them, people begin to suspect his sanity; and the man who would throw a brick into another's office at the risk of hurting some of the people employed there, in order to convince their principal that if he did not accept the religion the missionary preached he would go to hell, would probably be dealt with as a lunatic. The conduct of some of the women was quite as eccentric, but people may do insane-like things without being insane. That, however, is no reason for disregarding their eccentricities, which should be taken into account when dealing with them. If the women required to be fed artificially, it by no means follows that it was a proper thing to do so in prison. It certainly was indiscreet, and it is difficult to see how, if it was justifiable to resort to this measure in order to save the life of a prisoner, it could be argued that a medical officer would not be equally justified in cutting off the injured or diseased arm of a prisoner, in spite of his protestations, in order to save his life. It is one thing to place the liberties of men, and another thing altogether to place their lives in the hands of officials. There is no official and no number of officials--by whatever name called--good enough to be entrusted, unchecked by public observation, with the lives of their fellow-citizens; and there is no criminal bad enough to be immured from the public gaze and placed wholly under the control of anyone. It is not that the officials are bad; they are no worse than unofficial persons and no better, and there is far more danger from those who have gained a reputation for humanity and for enlightened opinions, even when they have deserved the reputation, than from the others, because the former are likely to be left more to themselves on account of their good name. Few who read this could be trusted to do as good a day's work at the end of the year as they did at the beginning, if there were not someone to check and criticise them.
