_P._ To answer that question fully would require volumes. Be content, then, for the present, with the following brief words: Hitherto science has been almost wholly materialistic in its tendencies, having nothing to do with spiritual things, but ignoring and casting doubts upon them; while _spiritual_ matters, on the other hand, have been regarded by the Church wholly as matters of faith with which science has nothing to do. But through these modern manifestations, God is providentially furnishing to the world all the elements of a spiritual science which, when established and recognized, will be the stand-point from which all physical science will be viewed. It will then be more distinctly known that all external and visible forms and motions originate from invisible, spiritual, and ultimately divine causes; that between cause and effect there is always a necessary and intimate _correspondence_; and hence that the whole outer universe is but the symbol and sure index of an invisible and _vastly more real_ universe within. From this unitary basis of thought the different sciences as now correctly understood may be co-related in harmonic order as One Grand Science, the _known_ of which, by the rule of correspondence, will lead by easy clews to the _unknown_. The true structure and government of human society will be clearly hinted by the structure and laws of the universe, and especially by that _microcosm_, or little universe, the human organization. All the great stirring questions of the day, including the questions of suffrage, woman's rights, the relations between labor and capital, and the questions of general political reform, will be put into the way of an easy and speedy solution; and mankind will be ushered into the light of a brighter day, socially, politically, and religiously, than has ever yet dawned upon the world. _I._ My invisible friend, the wonderful nature of your communication excites my curiosity to know your name ere we part. Will you have the kindness to gratify me in this particular? _P._ That I may not do. My name is of no consequence in any respect. Besides, if I should give it, you might, unconsciously to yourself, be influenced to attach to it the weight of a personal authority, which is specially to be avoided in communications of this kind. There is nothing to prevent deceiving spirits from assuming great names, and you have no way of holding them responsible for their statements. With thinkers--minds that are developed to a vigorous maturity--the truth itself should be its only and sufficient authority. If what I have told you appears intrinsically rational, logical, scientific, in harmony with known facts, and appeals to your convictions with the force of truth, accept it; if not, reject it; but I advise you not to reject it before giving it a candid and careful examination. I may tell you more at some future time, but for the present, farewell. CONCLUSION.
