He divided the Brothers he knew into four categories. In the first he put those who did not take an active part in the affairs of the lodges or in human affairs, but were exclusively occupied with the mystical science of the order: with questions of the threefold designation of God, the three primordial elements⁠—sulphur, mercury, and salt⁠—or the meaning of the square and all the various figures of the temple of Solomon. Pierre respected this class of Brothers to which the elder ones chiefly belonged, including, Pierre thought, Osip Alexéevich himself, but he did not share their interests. His heart was not in the mystical aspect of Freemasonry.

In the second category Pierre reckoned himself and others like him, seeking and vacillating, who had not yet found in Freemasonry a straight and comprehensible path, but hoped to do so.

In the third category he included those Brothers (the majority) who saw nothing in Freemasonry but the external forms and ceremonies, and prized the strict performance of these forms without troubling about their purport or significance. Such were Willarski and even the Grand Master of the principal lodge.
