The knowledge so required as a general and commonplace equipment requisite for the pursuit of these modern skilled occupations is of the general nature of applied mechanics, in which the essence of the undertaking is a ready apprehension of opaque facts, in passably exact quantitative terms. This class of knowledge presumes a certain intellectual or spiritual attitude on the part of the workman, such an attitude and animus as will readily apprehend and appreciate matter of fact and will guard against the suffusion of this knowledge with putative animistic or anthropomorphic subtleties, quasi-personal interpretations of the observed phenomena and of their relations to one another. The norm of systematisation is that given by the logic of the machine process, and the scope of it is that inculcated by statistical computation and the principle of material cause and effect. In some degree the routine of the machine industry necessarily induces such an animus in its employees, since such is the scope and method of its own working; and the closer and more exacting the application to work of this kind, the more thorough-going should be the effects of its discipline. But this routine and its discipline extend beyond the mechanical occupations as such, so as in great part to determine the habits of all members of the modern community. This proposition holds true more broadly for the current state of the industrial arts than any similar statement would hold, _e. g._, for the handicraft system. The ordinary routine of life is more widely and pervasively determined by the machine industry and by machine-like industrial processes today, and this determination is at the same time more rigorous, than any analogous effect that was had under the handicraft system. Within the effective bounds of modern Christendom no one can wholly escape or in any sensible degree deflect the sweep of the machine’s routine.
