accepted in our society should be adopted and obeyed. This is true, however, only because it is impossible for nearly all of us to investigate for ourselves and win personal convictions, and it is impossible for any of us to do so except in a few special matters. Nevertheless, all this sets out only in so much clearer light the pre-eminent value of science, because science extends, over the whole domain of human experience, a gradually wider and wider perception of those relations of man to earth and man to man on which human welfare depends. Science is investigation of facts by sound methods, and deduction of inferences by sound processes. The further it goes the more it enlightens us as to consequences which must ensue if acts are executed by which things and men are brought into the relations which science has elucidated. At the present moment civilized society stands at a point in the development of the applications of science to human interests, at which the thing of the highest importance is the subjection of societal phenomena to scientific investigation, together with the elimination of metaphysics from this entire domain.
