Natural history and psychology arrive at consciousness from the outside, and consequently give it an artificial articulation and rationality which are wholly alien to its essence. These sciences infer feeling from habit or expression; so that only the expressible and practical aspects of feeling figure in their calculation. But these aspects are really peripheral; the core is an irresponsible, ungoverned, irrevocable dream. Psychologists have discussed perception _ad nauseam_ and become horribly entangled in a combined idealism and physiology; for they must perforce approach the subject from the side of matter, since all science and all evidence is external; nor could they ever reach consciousness at all if they did not observe its occasions and then interpret those occasions dramatically. At the same time, the inferred mind they subject to examination will yield nothing but ideas, and it is a marvel how such a dream can regard those natural objects from which the psychologist has inferred it. Perception is in fact no primary phase of consciousness; it is an ulterior practical function acquired by a dream which has become symbolic of its conditions, and therefore relevant to its own destiny. Such relevance and symbolism are indirect and slowly acquired; their status cannot be understood unless we regard them as forms of imagination happily grown significant. In imagination, not in perception, lies the substance of experience, while knowledge and reason are but its chastened and ultimate form. [Sidenote: The mind vegetates uncontrolled save by physical forces.] Every actual animal is somewhat dull and somewhat mad. He will at times miss his signals and stare vacantly when he might well act, while at other times he will run off into convulsions and raise a dust in his own brain to no purpose. These imperfections are so human that we should hardly recognise ourselves if we could shake them off altogether. Not to retain any dulness would mean to possess untiring attention and universal interests, thus realising the boast about deeming nothing human alien to us; while to be absolutely without folly would involve perfect self-knowledge and self-control. The intelligent man known to history nourishes within a dullard and holds a lunatic in leash. He is encased in a protective shell of ignorance and insensibility which keeps him from being exhausted and confused by this too complicated world; but that integument blinds him at the same time to many of his nearest and highest interests. He is amused by the antics of the brute dreaming within his breast; he gloats on his passionate reveries, an amusement which sometimes costs him very dear. Thus the best human intelligence is still decidedly barbarous; it fights in heavy armour and keeps a fool at court. [Sidenote: Internal order supervenes.]
