Undoubtedly we _are_ forced to this conclusion. Not one of these primordial ideas, which find their synthesis in "the invisible companions of men," can be conceived without its opposite. And it is in the process of their unending struggle that the fuller realization of all of them is attained. And this struggle must inevitably assume a double character. It must assume the character of a struggle within the individual soul and of a struggle of the individual soul with other souls and with the universe. Such a struggle must be thought of as continually maintained in the soul of the "invisible companions of men" and maintained there with a depth of dramatic intensity at which we can only guess. Only less false and dangerous than the dogma that the absolute victory of good over evil has already been achieved, is the dogma that these two eternal antagonists are in reality one and the same thing. They are only one and the same thing in the sense that neither is thinkable without the other; and in the sense that they create the universe by their conflict. It is important in a matter as crucial as this matter, concerning "the invisible companions of men," not to advance a step beyond our starting-point till we have apprehended it from several different aspects and have gone over our ground again and again--even as builders of a bridge might test the solidity of their fabric stone by stone and arch by arch. By that "conscience in reason" which never allows us pleasantly to deceive ourselves, we are bound to touch, as it were with our very hands, every piece of stone work and every patch of cement which holds this desperate bridge together over the dark waters. We have not, then, a right to say that every energy of the complex vision depends for its functioning upon the existence of these invisible companions. We have not a right to say--"if there were no such beings these energies could not function; but they do function; therefore there are such beings." What we have a right to say is simply this, that it is an actual experience that when two or more personalities come together and seek to express their various subjective impressions of these ultimate ideas there is always a tacit reference to some objective standard.
