From the conversion of industry into a profession those who at present do its intellectual work have as much to gain as the manual workers. For the principle of function, for which we have pleaded as the basis of industrial organization, supplies the only intelligible standard by which the powers and duties of the different groups engaged in industry can be determined. At the present time no such standard exists. The social order of the pre-industrial era, of which faint traces have survived in the forms of academic organization, was marked by a careful grading of the successive stages in the progress from apprentice to master, each of which was distinguished by clearly defined rights and duties, varying from grade to grade and together forming a hierarchy of functions. The industrial system which developed in the course of the nineteenth century did not admit any principle of organization other than the convenience of the individual, who by enterprise, skill, good fortune, unscrupulous energy or mere nepotism, happened at any moment to be in a position to wield economic authority. His powers were what he could exercise; his rights were what at any time he could assert. The Lancashire mill-owner of the fifties was, like the Cyclops, a law unto himself. Hence, since subordination and discipline are indispensable in any complex undertaking, the subordination which emerged in industry was that of servant to master, and the discipline such as economic strength could impose upon economic weakness.
