When charity had thus accepted the necessity of using scientific methods there ensued immediate and far-reaching results. Chief of these have been the three developments which transformed charity into social work. It is possible to trace them in performance and to trace a parallel development of philosophy in the literature of the subject. These developments can be simply indicated as (1) a systematization of service; (2) an interest in causes of disaster, and (3) an extension of charitable interest into new fields.[20] THE SYSTEMATIZATION OF SERVICE The converts to a scientific method undertook to work within the traditional field of charity with a new thoroughness and system.[21] Fired with the belief of their times in a tenable norm of prosperity and a continuous progress dependent only on scientific control of our environment they naturally hoped that the most stubborn situation could be harmonized with the general melioration by the use of appropriate methods and they were no longer content to offer only relief, work, care for the helpless and such simple services as were once all that was thought of. They constantly challenged the applicability of old palliative expedients and looked for reconstructive measures. “For every one thing,” writes Miss Richmond, “that could then (1832) be done about a man’s attitude toward his life and his social relations, about his health, housing, work and recreation, there are now (1917) a dozen things to do. The power to analyze a human situation closely as distinguished from the old method of falling back upon a few general classifications, grows with the consciousness of the power to get things done.”[22] This change in expectation may be seen in the nomenclature of the tasks which social work has set itself. At first “relief” was the objective, then “_adequate_ relief” and now it is “rehabilitation.” The methods were, first the alternatives “relief” or “corrective treatment,” for there were sheep and goats in those days, then “preventive treatment” and now “adjustment.”
