The great importance of the contrast between the historic and the catastrophic points of view is, in the first place, that one way is on the whole right and the other on the whole wrong; but still more, that the patients whom we are going to deal with, and all the unfortunate or needy people whom the social assistant tries to help, are very fond of the wrong point of view and hang to it extraordinarily. It is _the_ natural first impression of any untrained person that his troubles "simply happen" without any explanation that he knows. So that we have to start at once to tear down a structure of innocent and lifelong belief on the part of the patient, that troubles come suddenly and by accident. We have to disillusion him, a process which naturally he does not take to particularly pleasantly. Our task in a dispensary is the same. The patient almost always starts with _the catastrophic point of view_, and can only be very gradually engineered into the other. And yet our work in relation to public health is largely to be summed up as finding out how,--that is by what history, through what chain of events, people come to be sick. Repetition and extension of disease can be checked only in case we succeed in finding such clues. Hence our labors to change people's point of view in this particular respect are as worth while as anything we can do, and we must not be discouraged by the fact that, week after week and year after year, we come up against the same difficulties, the same conviction, that troubles "just come" and have no cause.
