This generalization, which we saw variously illustrated by political institutions and ecclesiastical institutions, we now see again illustrated by professional institutions. As the foregoing chapters have shown, all the professions originate by differentiation from the agency which, beginning as political, becomes, with the apotheosis of the dead ruler, politico-ecclesiastical, and thereafter develops the professions chiefly from its ecclesiastical element. Egypt, which, by its records and remains, exhibits so well the early phases of social progress, shows us how at first various governmental functions, including the professional, were mingled in the king and in the cluster of those who surrounded the king. Says Tiele:—
And again—
And since, as Brugsch tells us, "Pharaoh's architects (the Murket) . . . were often of the number of the king's sons and grandsons," we see that in the governing group the political, ecclesiastical, and professional functions were united.
No group of institutions illustrates with greater clearness the process of social evolution; and none shows more undeniably how social evolution conforms to the law of evolution at large. The germs out of which the professional agencies arise, forming at first a part of the regulative agency, differentiate from it at the same time that they differentiate from one another; and, while severally being rendered more multiform by the rise of subdivisions, severally become more coherent within themselves and more definitely marked off. The process parallels completely that by which the parts of an individual organism pass from their initial state of simplicity to their ultimate state of complexity.
Originally one who was believed by himself and others to have power over demons—the mystery-man or medicine-man—using coercive methods to expel disease-producing spirits, stood in the place of doctor; and when his appliances, at first supposed to act supernaturally, came to be understood as acting naturally his office eventually lost its priestly character altogether: the resulting physician class, originally uniform, eventually dividing
