One of the curious psychological facts, in connection with the various ways in which various minds function, is the fact that when in these days we seek to visualize, in some pictorial manner, our ultimate view of life, the images which are called up are geometrical or chemical rather than anthropomorphic. It is probable that even the most rational and logical among us as soon as he begins to philosophize at all is compelled by the necessity of things to form in the mind some vague pictorial representation answering to his conception of the universe. The real inherent nature of such a philosophy would be probably understood and appreciated far better, both by the philosopher himself and by his friends, if this vague pictorial projection could be actually represented, in words or in a picture. Most minds see the universe of their mental conception as something quite different from the actual stellar universe upon which we all gaze. Even the most purely rational minds who find the universe in "pure thought" are driven against their rational will to visualize this "pure thought" and to give it body and form and shape and movement. These hidden and subconscious representations, in terms of sensible imagery, of the conclusions of philosophic thought, are themselves of profound philosophical interest. We cannot afford to neglect them. They are at least proof of the inalienable part played, in the functioning of our complex vision, by _sensation_ as an organ of research. But they have a further interest. They are an illuminating revelation of the inherent character and personal bias of the individual soul who is philosophizing. I suppose to a great many minds what we call "the universe" presents itself as a colossal circle, without any circumference, filled with an innumerable number of material objects floating in some thin attenuated ether. I suppose the centre of this circle with no circumference is generally assumed to be the "self" or "soul" of the person projecting this particular image. Doubtless, in some cases, it is assumed to be such a person's physical body as it feels itself conscious of sensation and is aware of space and time. As I myself use the expression "complex vision" I suppose I call up in the minds of my various readers an extraordinary variety of pictorial images. Without laying any undue stress upon this pictorial tendency, I should like to indicate the kind of projected image which I myself am conscious of, when I use the expression, "the complex vision." I seem to visualize this thing as a wavering, moving mass of flames, taking the shape of what might be called a "horizontal pyramid," the apex of which, where the flames are fused and lost in one another, is continually cleaving the darkness like the point of a fiery arrow, while the base of it remains continually invisible by reason of some magical power which confuses the senses whenever they seek to touch or to hold it.
