Whilst the following sheets were going through the press, my friend Mr. Newton, who has not only assisted me in a variety of ways, but who has taken a great deal of interest in the subject of symbolism, gave me to understand that there were some matters in which he differed very strongly from me in opinion. One of these was as to the correct interpretation of the so-called Assyrian grove; another was the signification of one of Lajard's gems, Plate iv., Fig. 3; and the most conspicuous of our divergencies was respecting the fundamental, or basic idea, which prompted the use in religion of those organs of reproduction which have, from time immemorial, been venerated in Hindostan, and, as far as we can learn, in Ancient Egypt, Babylonia, Assyria, Tyre, Sidon, Carthage, Jerusalem, Etruria, Greece, and Rome, as well as in countries called uncivilised. I feel quite disposed to acquiesce in the opinions which my old friend has formed respecting the Assyrian grove, but I am not equally ready to assent to his other opinions. Where two individuals are working earnestly for the elucidation of truth, there ought, in my opinion, to be not only a tolerance of disagreement, but an honest effort to submit the subject to a jury of thoughtful readers. As I should not feel satisfied to allow any other person to express my opinions in his words, it seemed to me only fair to Mr. Newton to give him the facility of enunciating his views in his own language. It was intended, originally, that my friend's observations upon the "grove" should be followed by a dissertation upon other relics of antiquity--notably upon that known as Stonehenge--but circumstances have prevented this design being carried into execution. When two individuals who have much in common go over the same ground, it is natural, indeed almost necessary, that they should dwell upon identical topics. Hence it will be found that there are points which are referred to by us both, although possibly in differing relationship. As my own part of the following remarks were printed long before I saw Mr. Newton's manuscript, I hope to be pardoned for allowing them to stand. The bulk of the volume will not be increased to the extent of a full page. If I were to be asked the reason why I differ from Mr. Newton in his exalted idea about the adoption of certain bodily organs as types, tokens, or emblems of an unseen and an inscrutable Creator, my answer would be drawn from the observations made upon every known order of priesthood, from the most remote antiquity to the present time. No matter what the creed, whether Ancient or Modern, the main object of its exponents and supporters is to gain over the minds of the populace. This has never yet been done, and probably never will be attempted, by educating the mind of the multitude to think. In Great Britain we find three sets of hierarchs opposed to each other, and all equally, by every means in their power, prohibit independent inquiry.
