exempt the operative employees from taking thought of pecuniary matters. Now, as to the bearing of all this upon cultural changes that are in progress or in the outlook. Leaving the "backward," relatively unspecialised, industries on one side, as being of an equivocal character for the point in hand and as not differing characteristically from the corresponding industries in the past so far as regards their disciplinary value; modern occupations may, for the sake of the argument, be broadly distinguished, as economic employments have been distinguished above, into business and industrial. The modern industrial and the modern business occupations are fairly comparable as regards the degree of intelligence required in both, if it be borne in mind that the former occupations comprise the highly trained technological experts and engineers as well as the highly skilled mechanics. The two classes of occupations differ in that the men in the pecuniary occupations work within the lines and under the guidance of the great institution of ownership, with its ramifications of custom, prerogative, and legal right; whereas those in the industrial occupations are, in their work, relatively free from the constraint of this conventional norm of truth and validity. It is, of course, not true that the work of the latter class lies outside the reach of the institution of ownership; but it is true that, in the heat and strain of the work, when the agent's powers and attention are fully taken up with the work which he has in hand, that of which he has perforce to take cognisance is not conventional law, but the conditions impersonally imposed by the nature of material things. This is the meaning of the current commonplace that the required close and continuous application of the operative in mechanical industry bars him out of all chance for an all-around development of the cultural graces and amenities. It is the periods of close attention and hard work that seem to count for most in the formation of habits of thought. An _a priori_ argument as to what cultural effects should naturally follow from such a difference in discipline between occupations, past and present, would probably not be convincing, as _a priori_ arguments from half-authenticated premises commonly are not. And the experiments along this line which later economic developments have so far exhibited have been neither neat enough, comprehensive enough, nor long continued enough to give definite results. Still, there is something to be said under this latter head, even if this something may turn out to be somewhat familiar.
