It is not only a stronger glass that the remote giant would need to disclose to him the life of the earth; he would need imagination akin to the human, which such a giant would probably not possess. For suppose anatomy had done its best or its worst, and had completely mapped the machinery of the human automaton; and suppose at the same time the modern dream-readers and diviners had unearthed all a man's infant concupiscences and secret thoughts: there would still be something essential undiscovered. I do not mean that behind the whole physical machinery there would be another material agency, another force or set of events; nor that besides the totality of mental discourse, remembered or unremembered, there would be more thinking elsewhere: the hypothesis is that all that exists in these spheres has been surveyed, and assigned to its place in the evolving system. What has been so far ignored is something on another plane of being altogether, which this automatic life and this mental discourse involve, but do not contain. It is the _principle_ of both and of their relation; the system of repetitions, correspondences, developments, and ideal unities created by this march of human life in double column. For instance, men are mortal; they are born; they are begotten by sexual fertilization; they have a childhood; their passions and thoughts flow in a certain general order; and there are units in the human world called persons, nations, interests, purposes. I do not refer to the _ideas_ of these things in the mental discourse of this or that man; but to the groups or cycles of facts designated by these ideas. To perceive these groups or cycles requires a certain type of intelligence: but intelligence does not invent them without cause; it _finds_ the order which it designates by some word, some metaphor, or some image.
