These hidden listeners, these tacit arbiters, these assumed and implied witnesses of our life, give value to every attempt we make at arriving at some unity amid our differences; and their vision seems, as the eternal duality presses upon us, to be at once the thing from which we start and the thing towards which, moulding the future as we go, we find ourselves moving. In the unfathomable depths of the past we are aware of a form, a shape, a principle, a premonition; and into the unfathomable depths of the future we project the fulfilled reality of this. We are as gods creating something out of nothing. But when we have created it . . . behold! it was there from the beginning; and the nothing out of which we have created it has receded into a second future from which it mocks and menaces us again. The full significance of this ultimate duality would be rendered abortive if the future were determined in any more definite way than by the premonition, the hope, the dream, the passion, the prophecy, the vision, of those invisible companions whose existence is implied whenever two separate souls communicate their thoughts to one another. It is by our will that the future is created; but around the will hover intermittently many unfathomable motives. And the pre-existent motive, which finally gives the shape to the future, holds the future already in its hand. And this surviving motive, ultimately selected by our will, is of necessity purged and tested by a continual comparison with that form, that idea, that dream, that vision, which is implied from the beginning and which I name "the vision of the invisible companions." The philosophical enquiry upon which we are engaged finds its starting point, then, in nothing less than that revelation of the complex vision which is also the goal of its journey. The complex vision, in the rhythmic play of its united attributes, makes use of a synthetic power which I call its apex-thought. The supreme activity of this apex-thought is centred about those primordial ideas of truth, beauty and nobility which are the very stuff and texture of its being. In the ecstasy of its creative and receptive "rapport" with these it becomes aware of the presence of certain immortal companions whose vision is at once the objective standard of such ideas and the premonition of their fuller realization. In thus attempting to articulate and clarify the main outlines of our starting point, a curious situation emerges. The actual _spectacle_, or mass of impressions to be dealt with, presents itself, we are forced to suppose, as more or less identical, in its general appearance, in every human consciousness. And this "general situation" is strange enough.
