These nineteen propositions, which have been submitted in the present essay, constitute a brief summary or outline of a theory of the true origin of Freemasonry, which long and patient investigation has led me to adopt. To attempt to prove the truth of each of these propositions in its order by logical demonstration, or by historical evidence, would involve the writing of an elaborate treatise. They are now offered simply as suggestions on which the Masonic student may ponder. They are but intended as guide-posts, which may direct him in his journey should he undertake the pleasant although difficult task of instituting an inquiry into the origin and progress of Freemasonry from its birth to its present state of full-grown manhood. But even in this abridged form they are absolutely necessary as preliminary to any true understanding of the symbolism of Freemasonry. II. The Noachidæ. I proceed, then, to inquire into the historical origin of Freemasonry, as a necessary introduction to any inquiry into the character of its symbolism. To do this, with any expectation of rendering justice to the subject, it is evident that I shall have to take my point of departure at a very remote era. I shall, however, review the early and antecedent history of the institution with as much brevity as a distinct understanding of the subject will admit. Passing over all that is within the antediluvian history of the world, as something that exerted, so far as our subject is concerned, no influence on the new world which sprang forth from the ruins of the old, we find, soon after the cataclysm, the immediate descendants of Noah in the possession of at least two religious truths, which they received from their common father, and which he must have derived from the line of patriarchs who preceded him. These truths were the doctrine of the existence of a Supreme Intelligence, the Creator, Preserver, and Ruler of the Universe, and, as a necessary corollary, the belief in the immortality of the soul[1], which, as an emanation from that primal cause, was to be distinguished, by a future and eternal life, from the vile and perishable dust which forms its earthly tabernacle. The assertion that these doctrines were known to and recognized by Noah will not appear as an assumption to the believer in divine revelation. But any philosophic mind must, I conceive, come to the same conclusion, independently of any other authority than that of reason. The religious sentiment, so far, at least, as it relates to the belief in the existence of God, appears to be in some sense innate, or instinctive, and consequently universal in the human mind[2]. There is no record of any nation, however intellectually and morally debased, that has not given some evidence of a tendency to such belief. The sentiment may be perverted, the idea may be grossly corrupted, but it is nevertheless there, and shows the source whence it sprang[3].
