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.
Sometimes I seem to see this "base" or "spear handle" or "arrow shaft," of my moving horizontal pyramid, as a kind of deeper darkness; sometimes as a vibration of air; sometimes as a cloud of impenetrable smoke. I am always conscious of the curious fact that, while I can most vividly see the apex-point of the thing, and while I know that this moving pyramid of fire has a base, there is for ever some drastic natural law or magical power at work that obscures my vision whenever I turn my eyes to the place where I know it exists.
I have not mentioned this particular pictorial image with any wish to lay undue stress upon it. In all rarified and subtle experiments of thought pictorial images are quite as likely to hinder us in our groping towards reality as they are to help us. If my image of a moving, horizontal pyramid with an apex-point of many names fused into one and a base of impenetrable invisibility seems to any reader of this passage a ridiculous and arbitrary fancy I would merely ask such an one to let it go, and to consider my description of the complex vision quite independently of it.
Sometimes to myself it appears ridiculous; and I only, as we put it, "throw it out" in order that, if it has the least illuminative value, such a value should not be quite lost. Any reader who regards my particular picture as absurd is perfectly at liberty to form his own pictorial image of what I am endeavouring to make clear. He may, if he pleases, visualize "the soul" as a sort of darkened planet from which the attributes of the complex vision radiate to the right or to the left, as the thing moves through immensity. All I ask is that these attributes should be thought of as converging to a point and as finding their "base" in some thing which is felt to exist but cannot be described.
Probably to a thorough-going empiricist, and certainly to a thorough-going materialist, it will appear quite unnecessary to translate the obvious spectacle of the world, with oneself as a physical body in the centre of it, into mental symbols and pictorial representations of the above character. Of such an one I would only ask, in what sort of manner he visualizes, when he thinks of it at all, the "soul" which he feels conscious of in his own body; and in the second place how he visualizes the connection between the will, the instinct, the reason and so forth, which animate his body and endow it with living purpose? It will be found much easier for critics to reject the particular image which has commended itself to me as suggestive of the mystery with which we have to deal, than for them to drive out and expel from their own thought the insidious human tendency towards pictorial representation.
I would commend to any sardonic psychologist whose "malice" leads him to derive pleasure from the little weaknesses of philosophers, to turn his attention to the ideal systems of supposedly "pure thought." He will find infinite satisfaction for his spleen in the crafty manner in which "impure" thought—that is to say thought by means of pictorial images—passes itself off as "pure" and conceals its lapses.
Truth, as the complex vision clearly enough reveals to us, refuses to be dealt with by "pure" thought. To deal with truth one has to use "impure" thought, in other words thought that is dyed in the grain by taste, instinct, intuition, imagination. And every philosopher who attempts to round off his system by pure reason alone, and who refuses to recognize that the only adequate organ of research is the complex vision, is a philosopher who sooner or later will be caught red-handed in the unphilosophic act of covering his tracks.
No philosopher is on safe ground, no philosopher can offer us a massive organic concrete representation of reality who is shy of all pictorial images. They are dangerous and treacherous things; but it is better to be led astray by them than to avoid them altogether.
