Advancing in his progress, the candidate is invited to contemplate another series of instructions. The human senses, as the appropriate channels through which we receive all our ideas of perception, and which, therefore, constitute the most important sources of our knowledge, are here referred to as a symbol of intellectual cultivation. Architecture, as the most important of the arts which conduce to the comfort of mankind, is also alluded to here, not simply because it is so closely connected with the operative institution of Masonry, but also as the type of all the other useful arts. In his second pause, in the ascent of the Winding Stairs, the aspirant is therefore reminded of the necessity of cultivating practical knowledge.
So far, then, the instructions he has received relate to his own condition in society as a member of the great social compact, and to his means of becoming, by a knowledge of the arts of practical life, a necessary and useful member of that society.
But his motto will be, “Excelsior.” Still must he go onward and forward. The stair is still before him; its summit is not yet reached, and still further treasures of wisdom are to be sought for, or the reward will not be gained, nor the middle chamber, the abiding place of truth, be reached.
In his third pause, he therefore arrives at that point in which the whole circle of human science is to be explained. Symbols, we know, are in themselves arbitrary and of conventional signification, and the complete circle of human science might have been as well symbolized by any other sign or series of doctrines as by the seven liberal arts and sciences. But Masonry is an institution of the olden time; and this selection of the liberal arts and sciences as a symbol of the completion of human learning is one of the most pregnant evidences that we have of its antiquity.
In the seventh century, and for a long time afterwards, the circle of instruction to which all the learning of the most eminent schools and most distinguished philosophers was confined, was limited to what were then called the liberal arts and sciences, and consisted of two branches, the trivium and the quadrivium.[154] The trivium included grammar, rhetoric, and logic; the quadrivium comprehended arithmetic, geometry, music, and astronomy.
