Humorous irony shines through most of the harsh glances turned towards the idea of an experimental basis and career for morals. Some shiver in the fear that morals will be plunged into anarchic confusion--a view well expressed by a recent writer in the saying that if the _a priori_ and transcendental basis of morals be abandoned “we shall have merely the same certainty that now exists in physics and chemistry”! Elsewhere lurks the apprehension that the progress of scientific method will deliver the purposive freedom of man bound hand and foot to the fatal decrees of iron necessity, called natural law. The notion that laws govern and forces rule is an animistic survival. It is a product of reading nature in terms of politics in order to turn around and then read politics in the light of supposed sanctions of nature. This idea passed from medieval theology into the science of Newton, to whom the universe was the dominion of a sovereign whose laws were the laws of nature. From Newton it passed into the deism of the eighteenth century, whence it migrated into the philosophy of the Enlightenment, to make its last stand in Spencer’s philosophy of the fixed environment and the static goal. No, nature is not an unchangeable order, unwinding itself majestically from the reel of law under the control of deified forces. It is an indefinite congeries of changes. Laws are not governmental regulations which limit change, but are convenient formulations of selected portions of change followed through a longer or shorter period of time, and then registered in statistical forms that are amenable to mathematical manipulation. That this device of shorthand symbolization presages the subjection of man’s intelligent effort to fixity of law and environment is interesting as a culture survival, but is not important for moral theory. Savage and child delight in creating bogeys from which, their origin and structure being conveniently concealed, interesting thrills and shudders may be had. Civilized man in the nineteenth century outdid these bugaboos in his image of a fixed universe hung on a cast-iron framework of fixed, necessary, and universal laws. Knowledge of nature does not mean subjection to predestination, but insight into courses of change; an insight which is formulated in “laws,” that is, methods of subsequent procedure.
