As the term implies, applied sociology treats of techniques for improving the quality of human living. The best techniques have been developed experimentally, but by persons who have combined a high estimate of social theory with practical programs of activity. The useful concept of social technology, a more accurate term perhaps than applied sociology, was given to society by Charles R. Henderson, whose balanced thinking, sane judgment, and important ameliorative activities made him the founder of this branch of sociological science. Dr. Henderson’s name is synonymous with a practical interpretation of both democracy and Christianity, with the spirit of vigorous yet kindly reformation in penology, with the concept of prevention in philanthropic endeavors, and with justice and love in all the fields of human achievement. There are many other important names in the list of those persons who helped to found applied sociology; for example, such individuals as Canon Barnett, Arnold Toynbee, Jacob Riis, Jane Addams, and many other social welfare saints. Poverty and crime have been the two chief phenomena with which welfare work has been concerned. Until the present century the attempts to meet the problems of poverty have been largely remedial. Jesus said that the poor are always present in any age of society. St. Francis of Assisi, tiring of monastery life, sought out the poor in the natural walks of life, and dedicated himself in their behalf. For centuries England has experimented with solutions for the problems of poverty and pauperism. She has learned that when she cares too assiduously for the poor she encourages the spirit of pauperism and increases the numbers of dependents. When she provided liberal aid for illegitimate children, she found that illegitimacy was furthered. England has had a series of important literary leaders who have interested themselves in behalf of the poor and outcast. Dickens drew minute word pictures of poverty. Carlyle, the iconoclast and individualist, pierced repeatedly the shams of society which are partly responsible for the perpetual existence of social misery. In beautiful diction Ruskin spoke in behalf of social justice. In similar fields, France has her Hugo and Balzac; Germany, her Hauptmann; Russia, her Tolstoi and Gorky; Scandinavia, her Bjornson, Ibsen, and Strindberg. Individuals of this type, however, cannot be considered social technologists. They have directed public opinion to specific social problems, but rarely offered technological programs of practical value.
