In the masonic system there are two temples; the first temple, in which the degrees of Ancient Craft Masonry are concerned, and the second temple, with which the higher degrees, and especially the Royal Arch, are related. The first temple is symbolic of the present life; the second temple is symbolic of the life to come. The first temple, the present life, must be destroyed; on its foundations the second temple, the life eternal, must be built. But the mystical stone was placed by King Solomon in the foundations of the first temple. That is to say, the first temple of our present life must be built on the sure foundation of divine truth, "for other foundation can no man lay." But although the present life is necessarily built upon the foundation of truth, yet we never thoroughly attain it in this sublunary sphere. The Foundation Stone is concealed in the first temple, and the Master Mason knows it not. He has not the true word. He receives only a substitute. But in the second temple of the future life, we have passed from the grave, which had been the end of our labors in the first. We have removed the rubbish, and have found that Stone of Foundation which had been hitherto concealed from our eyes. We now throw aside the substitute for truth which had contented us in the former temple, and the brilliant effulgence of the tetragrammaton and the Stone of Foundation are discovered, and thenceforth we are the possessors of the true word--of divine truth. And in this way, the Stone of Foundation, or divine truth, concealed in the first temple, but discovered and brought to light in the second, will explain that passage of the apostle, "For now we see through a glass darkly, but then face to face: now I know in part; but then shall I know even as also I am known." And so, the result of this inquiry is, that the masonic Stone of Foundation is a symbol of divine truth, upon which all Speculative Masonry is built, and the legends and traditions which refer to it are intended to describe, in an allegorical way, the progress of truth in the soul, the search for which is a Mason's labor, and the discovery of which is his reward. XXXI. The Lost Word. The last of the symbols, depending for its existence on its connection with a myth to which I shall invite attention, is _the Lost Word, and the search for it_. Very appropriately may this symbol terminate our investigations, since it includes within its comprehensive scope all the others, being itself the very essence of the science of masonic symbolism. The other symbols require for their just appreciation a knowledge of the origin of the order, because they owe their birth to its relationship with kindred and anterior institutions. But the symbolism of the Lost Word has reference exclusively to the design and the objects of the institution. First, let us define the symbol, and then investigate its interpretation.
