But what he does insist upon is that we must beware of mixing sentimentality with the business, that we must keep the idea of expediency clear of any idea of altruism. The trouble with the world, as he describes it, is that such a corruption almost always takes place. That is to say, we too often practise charity, not because it is worth while, but merely because it is pleasant. The Christian ideal, he says, "knows how to enrapture." Starting out from the safe premise, approved by human experience, that it is sometimes a virtue--_i.e._, a measure of intelligent prudence--to help the weak, we proceed to the illogical conclusion that it is _always_ a virtue. Hence our wholesale coddling of the unfit, our enormous expenditure upon vain schemes of amelioration, our vain efforts to combat the laws of nature. We nurse the defective children of the lower classes into some appearance of health, and then turn them out to beget their kind. We parole the pickpocket, launch him upon society with a tract in his hand--and lose our pocket-books next day. We send missionaries to the heathen, build hospitals for them, civilize and educate them--and later on have to fight them. We save a pauper consumptive today, on the ostensible theory that he is more valuable saved than dead--and so open the way for saving his innumerable grandchildren in the future. In brief, our self-sacrifice of expediency seldom remains undefiled. Nine times out of ten a sentimental color quickly overcomes it, and soon or late there is apt to be more sentimentality in it than expediency.
