=3. The Present Significance and Task of Scientific Method.=--In the thought that man is able to form ends which have value for all, to set up standards which all respect, and thus to achieve worth and dignity in the estimation of his fellows, the Individualism of the eighteenth century was already pointing beyond itself. For this meant that the individual attains his highest reach only as a member of a moral society. But it is one thing to point out the need and meaning of a moral society, it is another thing to bring such a society into being. It has become evident during the past century that this is the central problem for human reason to solve. The various social sciences, economics, sociology, political science, jurisprudence, social psychology, have either come into being for the first time, or have been prosecuted with new energy. Psychology has assumed new significance as their instrument. Not that the scientific progress of the century has seen its greatest triumphs in these fields. The conspicuous successes have been rather in such sciences as biology, or in the applications of science to engineering and medicine. The social sciences have been occupied largely in getting their problems stated and their methods defined. But the discoveries and constructions of the nineteenth century are none the less indispensable prerequisites for a moral society. For the new conditions of city life, the new sources of disease, the new dangers which attend every successive step away from the life of the savage, demand all the resources of the sciences.[94] And as the natural sciences overcome the technical difficulties which obstruct their work of aiding human welfare, the demand will be more insistent that the social sciences contribute their share toward enabling man to fulfil his moral life. Some of the specific demands will become more evident, as we study in subsequent chapters the present problems of political, economic, and family life.
