All mysteries are said to be either truths concealing deeper truths, or errors concealing deeper errors; and thus, as the mysteries unfold, truth or error will show itself in a gradually clearer light, enabling us to distinguish between the two. It is now left for men of science to decide as to the nature of the mysteries which Keely is slowly unfolding, and whether his demonstrations substantiate his theories. They have been invited to follow him in his experimental research, step by step; to bestow upon him sympathy and encouragement, so long withheld, until he reaches that stage where he will no longer need their protection. Then, if science is satisfied that he has gained a treasure for her, in his years of dead-work, she must step aside and wait patiently until he has fulfilled his obligations to those who organized themselves into a company to aid him, long before she came forward to interest herself in his behalf. Those men of science who have refused to countenance this great work, even by witnessing experiments made to prove the discovery of an unknown force, are men who attempt no explanation of the miracles of nature by which we are surrounded, assuming that no explanation can be given; but, as Bacon has said, he is a bad mariner, who concludes, when all is sea around him, that there is no land beyond. If the multitude of so-called laws of nature could be resolved into one grand universal law, would it not be considered a great step in the progress of scientific knowledge? This is what our pioneer claims for his discoveries, one law working throughout nature, in all things; for, as Macvicar says, the productive and conservative agency in creation, as it exists and acts, does not consist of two things, "idea" and "power"; but of a unity embracing both, for which there is no special name. The relation between the Creator and the Creation, the First Cause and what he has effected, is altogether inscrutable; but intelligence acting analytically, as it cannot be kept from doing, insists on these two elements in the problem, viz. idea and power. "The law of the universe is a distinct dualism while the creative energies are at work; and of a compound union when at rest."
