Confronted with people's troubles, whether physical or mental or spiritual, we are tempted, and above all _they_ are tempted to regard the sickness, the poverty, or the sorrow in the light of an emergency, an accident, and therefore as something to be treated at once and by means which have little to do with the past and the future. On the other hand, the standpoint of science and philosophy, and of any one who has labored long in the field of social work with or without science or philosophy, is the point of view of history. This is the habit of mind which makes us believe that a supposed "accident" belongs in a long sequence, a long chain of events, so that it is impossible to understand or to help it without knowledge, as extensive as our time and our wisdom will allow, of that whole chain. Consider a few examples which contrast these two points of view. When a boy is brought into court for stealing, it is almost always his attempt, and the attempt of those who defend him, to show that such a thing has never happened in his life before; he "just _happened_ to steal." But as we inquire more closely into the facts, we almost always find that this is a fundamentally untrue statement of the case. For the offence which brought him into court is almost never the first offence. He has always stolen before. On the present occasion he was a member of a boy's gang; it was not in the least accidental that he got into that group of boys. As we search back in his history, and perhaps into his father's history, we find reasons why he is what he is now. Again, we are trying to help some wayward girl who has taken an immoral step. We are told what a wholly unforeseeable _accident_ it was that got her into her trouble. But if we can get a good picture of her past, we find that we could have traced the tendency to weakness of this kind from the time she was born. So it is in medical matters. _Emergencies are rare._ I remember being called out of a sound sleep one night to go "as quickly as possible" to see a man who had discovered a lump upon his breast bone. He was quite sure that the swelling had appeared since the time when he went to bed. It was then one o'clock in the morning, and he had gone to bed at eleven. Well, I found a slight bony irregularity in his breast bone which doubtless had been there about forty-five years, as he was forty-six years old. He did not pretend that it hurt him, and did not undertake to show that he was ill in any other way. But this lump had come and naturally he wanted help at once.
