The great law of sympathetic association, once understood, will become known as it is,--viz., as the governing medium of the universe. Herein lies the secret, the revelation of which will usher in the spiritual age foretold by the Prophets of the Old Testament and the Apostles of the New Testament. Inspiration is not confined to prophets and apostles and poets: the man of science, the writer, all who reach out after the Infinite, receive their measure of inspiration according to their capacity. We need a new revelation to turn back "the tidal wave of materialism" which has rolled in upon the scientific world, as much as Moses needed one when he sought to penetrate the mysteries of the Creation; and our revelation is near at hand,--a revelation which will change the statical "I am" into the dynamical "I will,"--a revelation which, while teaching us to look from Nature up to Nature's God, will reveal to us our own powers as "children of God," as "heirs of immortality." "Knowledge," said Lord Beaconsfield, "is like the mystic ladder in the Patriarch's dream. Its base rests on the primeval earth--its crest is lost in the shadowy splendour of the empyrean; while the great authors who, for traditionary ages, have held the chain of science and philosophy, of poesy and erudition, are the angels ascending and descending the sacred scale, maintaining, as it were, the communication between man and heaven." This beautiful imagery holds within it that seed of truth, which is said to exist in the wildest fable; for, although all great discoveries, pertaining to the material world, have been made gradually, with much starting on the wrong track, much false deduction and much worthless result, spiritual truths can be revealed to man in no other way than by that spiritual influence which maintains communication between the terrestrial and the celestial, or the material and the spiritual. "Truth is attained through immediate intuition," say the Aryan teachers; but only by those who have educated their sixth sense; as will be seen in Mr. Sinclair's new work, "Vera Vita; or, the Philosophy of Sympathy." While the imaginative scientist is puzzling himself about new natural forces and the apparent suspension of old and hitherto invariable laws, Sinclair, in his writings, shows us that it is because we do not recognize the elements of nature that their influences remain mysterious to us. Mr. Sinclair is as firm in his belief as is Mr. Keely that this element is the great connecting link between the Creator and the created, and that it is capable of rendering more marvellous services to man than all the discovered uses of electricity.
