Knowledge of the process and conditions of physical and social change through experimental science and genetic history has one result with a double name: increase of control, and increase of responsibility; increase of power to direct natural change, and increase of responsibility for its equitable direction toward fuller good. Theory located within progressive practice instead of reigning statically supreme over it, means practice itself made responsible to intelligence; to intelligence which relentlessly scrutinizes the consequences of every practice, and which exacts liability by an equally relentless publicity. As long as morals occupies itself with mere ideals, forces and conditions as they are will be good enough for “practical” men, since they are then left free to their own devices in turning these to their own account. As long as moralists plume themselves upon possession of the domain of the categorical imperative with its bare precepts, men of executive habits will always be at their elbows to regulate the concrete social conditions through which the form of law gets its actual filling of specific injunctions. When freedom is conceived to be transcendental, the coercive restraint of immediate necessity will lay its harsh hand upon the mass of men. In the end, men do what they can do. They refrain from doing what they cannot do. They do what their own specific powers in conjunction with the limitations and resources of the environment permit. The effective control of their powers is not through precepts, but through the regulation of their conditions. If this regulation is to be not merely physical or coercive, but moral, it must consist of the intelligent selection and determination of the environments in which we act; and in an intelligent exaction of responsibility for the use of men’s powers. Theorists inquire after the “motive” to morality, to virtue and the good, under such circumstances. What then, one wonders, is their conception of the make-up of human nature and of its relation to virtue and to goodness? The pessimism that dictates such a question, if it be justified, precludes any consideration of morals.
