Such a nature, be it especially observed, is the basic condition, if not also the very inspiration of our modern industrialism. This industrial age, struggling against the old-time militarism, in its religion, in its art and in its literature, in its leisure and in its labour, in city and in country, is an age of machinery; of machinery in all the manifold forms demanded by all the various departments of human life, not of wheels and belts alone; an age of the conscious employment, for human purposes, of the resources of all sorts, the materials and the forces which the natural environment affords. Freedom, not slavery, is recognized as man's ideal portion, and in order to ensure the freedom, not human nature, but physical nature is mechanicalized; or, with the same intent, all the formal means, or instruments, of life are taken as incidents of environment, not as essential to man. So is industrialism supplanting the old-time militarism that sought, in all the relations of life, to identify the human with the instrumental. Witness the values now put upon theories and creeds, upon rites and institutions, upon personal habits and social laws. All of these, to begin with, are means, not ends; and, further, they are means whose devising--so man is insisting, as never before--must be, as near as possible, true to nature. The sovereign conviction of this age of industrialism appears to be that the only sure way to human freedom is the way of nature; employment of such instruments as she can supply; obedience to such law as she may disclose.
