It is significant, not only as an evidence of their close affiliation with the priestly craft, but also as indicating that their activity to a good extent falls under that category of conspicuous leisure known as manners and breeding, that the learned class in all primitive communities are great sticklers for form, precedent, gradations of rank, ritual, ceremonial vestments, and learned paraphernalia generally. This is of course to be expected, and it goes to say that the higher learning, in its incipient phase, is a leisure-class occupation--more specifically an occupation of the vicarious leisure class employed in the service of the supernatural leisure class. But this predilection for the paraphernalia of learning goes also to indicate a further point of contact or of continuity between the priestly office and the office of the savant. In point of derivation, learning, as well as the priestly office, is largely an outgrowth of sympathetic magic; and this magical apparatus of form and ritual therefore finds its place with the learned class of the primitive community as a matter of course. The ritual and paraphernalia have an occult efficacy for the magical purpose; so that their presence as an integral factor in the earlier phases of the development of magic and science is a matter of expediency, quite as much as of affectionate regard for symbolism simply. This sense of the efficacy of symbolic ritual, and of sympathetic effect to be wrought through dexterous rehearsal of the traditional accessories of the act or end to be compassed, is of course present more obviously and in larger measure in magical practice than in the discipline of the sciences, even of the occult sciences. But there are, I apprehend, few persons with a cultivated sense of scholastic merit to whom the ritualistic accessories of science are altogether an idle matter. The very great tenacity with which these ritualistic paraphernalia persist through the later course of the development is evident to any one who will reflect on what has been the history of learning in our civilization. Even today there are such things in the usage of the learned community as the cap and gown, matriculation, initiation, and graduation ceremonies, and the conferring of scholastic degrees, dignities, and prerogatives in a way which suggests some sort of a scholarly apostolic succession. The usage of the priestly orders is no doubt the proximate source of all these features of learned ritual, vestments, sacramental initiation, the transmission of peculiar dignities and virtues by the imposition of hands, and the like; but their derivation is traceable back of this point, to the source from which the specialized priestly class proper came to be distinguished from the sorcerer on the one hand and from the menial servant of a temporal master on the other hand. So far as regards both their derivation and their psychological content, these usages and the
