A compilation of Macvicar's "Sketch of a Philosophy," entitled "Ether the true Protoplasm," was sent to Mr. Keely; and shortly after, Mrs. Hughes' book on the evolution of tones and colours. Mr. Keely will himself, in his theoretical exposé make known the manner in which he was led, by the writings of Dr. Macvicar and Mrs. Hughes, into the knowledge which raised the veil that had before hidden from him the operations of Nature with this "the most powerful and most general of all her forces;" operations which will explain all that is now mysterious to us in the workings of gravity. The question has been asked whether science, having destroyed faith, has supplied us with anything better. But has science destroyed faith? Certainly not. There would be no such thing as counterfeit coin were it not for the existence of sterling gold. True science has its counterfeit, and it is due to spurious science that the bulwarks of religious faith have been besieged; but they are not destroyed. Drummond says that it will be the splendid task of the future theology to disclose to scepticism the naturalness of the supernatural. The pure Philosophy which true science seems about to reveal discloses not a universe of dead matter, but a universe alive from its core to its outermost extremity, and animated by mind and means, to which matter, perfectly organized, is absolutely subservient. It illuminates mysteries of nature which have only been partially revealed to us, and lifts the veil which has hitherto shrouded in darkness still greater mysteries involved in this universal power, which keeps and sustains all systems of worlds in their relation towards each and all. More and more clearly shall we be led by true science to see that the universe "is founded upon a distinct idea," and that the harmony of this distinct idea is manifested in all of God's works. Sir Isaac Newton, in his "Fundamental Principles of Natural Philosophy," calls the great magnetic agent "the soul of the world," and says, "all senses are excited by this spirit, and through it the animals move their limbs; but these things cannot be explained in few words, and we have not yet sufficient experience to determine fully the laws by which this universal spirit operates." Centuries may pass before these laws will be "fully understood"; but Etheric Philosophy casts a plummet into depths that have never been sounded, and reveals this "unparticled substance," "the cosmic matter," "the primal stuff," "the celestial ocean of universal ether," as the true protoplasm, and the medium by which mind shapes matter and gives it all its properties. It teaches us that, through it, we are connected in sympathy with all other souls and with all the objects of nature, even, to the stars and all the heavenly bodies. But even though we do not understand the laws which control its operations, we find therein a legitimate field of research. It is surely more legitimate for
