All the monuments of antiquity that the ravages of time have left, combine to prove that man had no sooner emerged from the savage into the social state, than he commenced the organization of religious mysteries, and the separation, by a sort of divine instinct, of the sacred from the profane. Then came the invention of architecture as a means of providing convenient dwellings and necessary shelter from the inclemencies and vicissitudes of the seasons, with all the mechanical arts connected with it; and lastly, geometry, as a necessary science to enable the cultivators of land to measure and designate the limits of their possessions. All these are claimed as peculiar characteristics of Speculative Masonry, which may be considered as the type of civilization, the former bearing the same relation to the profane world as the latter does to the savage state. Hence we at once see the fitness of the symbolism which commences the aspirant's upward progress in the cultivation of knowledge and the search after truth, by recalling to his mind the condition of civilization and the social union of mankind as necessary preparations for the attainment of these objects. In the allusions to the officers of a lodge, and the degrees of Masonry as explanatory of the organization of our own society, we clothe in our symbolic language the history of the organization of society. 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.
