To the first grade of the third class, that of Priest,[385] were admitted only such members as, in the grade Minerval, had given proof of their zeal and advancement in the particular sciences which they had chosen.[386] The initiatory ceremonies of the grade emphasized the wholly unsatisfactory character of existing political and religious systems and sounded the candidate’s readiness to serve the order in its efforts to lead the race away from the vain inventions of civil constitutions and religious dogmas from which it suffered.[387] Relieved entirely of administrative responsibilities, the members of this grade devoted themselves exclusively to the instruction of their subordinates in the following branches of science: physics, medicine, mathematics, natural history, political science, the arts and crafts, and the occult sciences. In brief, the final supervision of the teaching function of the order was in their hands, subject only to the ultimate authority of their supreme heads.[388] Knigge’s statutes provided that only a very small number of members were to be admitted to the grade of Prince.[389] From this group the highest functionaries of the order were to be drawn: National Inspectors, Provincials,[390] Prefects, and Deans of the Priests. Over them, in turn, at the apex of the system and as sovereign heads of the order, ruled the Areopagites.[391] So much for the external structure of the system which Knigge reshaped. With respect to the aims and principles of the order the modifications introduced by him were considerable, although scarcely as comprehensive as in the former case.[392] In certain instances the ideas of Weishaupt were retained and developed;[393] in others significant alterations were made or new ideas introduced. Of the new ideas the two following were unquestionably of greatest weight:[394] the notion of restricting the field of recruiting solely to the young was abandoned, and this phase of the propaganda was widened so as to include men of experience whose wisdom and influence might be counted upon to assist in attaining the objects of the order;[395] the policy was adopted that henceforth the order should not occupy itself with campaigns against particular political and religious systems, but that its energies should be exerted against superstition, despotism, and tyranny.[396] In other words, the battle for tolerance and enlightenment should be waged along universal and not local lines. Accordingly, the esoteric teaching of the order, under Knigge’s revision, was reserved to the higher grades.
