The plumb is a symbol of rectitude of conduct, and inculcates that integrity of life and undeviating course of moral uprightness which can alone distinguish the good and just man. As the operative workman erects his temporal building with strict observance of that plumb-line, which will not permit him to deviate a hair's breadth to the right or to the left, so the speculative Mason, guided by the unerring principles of right and truth inculcated in the symbolic teachings of the same implement, is steadfast in the pursuit of truth, neither bending beneath the frowns of adversity nor yielding to the seductions of prosperity.[61] The level, the last of the three working tools of the operative craftsman, is a symbol of equality of station. Not that equality of civil or social position which is to be found only in the vain dreams of the anarchist or the Utopian, but that great moral and physical equality which affects the whole human race as the children of one common Father, who causes his sun to shine and his rain to fall on all alike, and who has so appointed the universal lot of humanity, that death, the leveller of all human greatness, is made to visit with equal pace the prince's palace and the peasant's hut.[62] Here, then, we have three more signs or hieroglyphics added to our alphabet of symbolism. Others there are in this degree, but they belong to a higher grade of interpretation, and cannot be appropriately discussed in an essay on temple symbolism only. We now reach the third degree, the Master Masons of the modern science, and the Epopts, or beholders of the sacred things in the ancient Mysteries.
