When the child of poetic genius, who has learned this intellectual and utilitarian language in the cradle, goes afield and gathers for himself the aspects of Nature, he begins to encumber his mind with the many living impressions which the intellect rejected, and which the language of the intellect can hardly convey; he labours with his nameless burden of perception, and wastes himself in aimless impulses of emotion and revery, until finally the method of some art offers a vent to his inspiration, or to such part of it as can survive the test of time and the discipline of expression.
The poet retains by nature the innocence of the eye, or recovers it easily; he disintegrates the fictions of common perception into their sensuous elements, gathers these together again into chance groups as the accidents of his environment or the affinities of his temperament may conjoin them; and this wealth of sensation and this freedom of fancy, which make an extraordinary ferment in his ignorant heart, presently bubble over into some kind of utterance.
The fulness and sensuousness of such effusions bring them nearer to our actual perceptions than common discourse could come; yet they may easily seem remote, overloaded, and obscure to those accustomed to think entirely in symbols, and never to be interrupted in the algebraic rapidity of their thinking by a moment's pause and examination of heart, nor ever to plunge for a moment into that torrent of sensation and imagery over which the bridge of prosaic associations habitually carries us safe and dry to some conventional act. How slight that bridge commonly is, how much an affair of trestles and wire, we can hardly conceive until we have trained ourselves to an extreme sharpness of introspection. But psychologists have discovered, what laymen generally will confess, that we hurry by the procession of our mental images as we do by the traffic of the street, intent on business, gladly forgetting the noise and movement of the scene, and looking only for the corner we would turn or the door we would enter. Yet in our alertest moment the depths of the soul are still dreaming; the real world stands drawn in bare outline against a background of chaos and unrest. Our logical thoughts dominate experience only as the parallels and meridians make a checker-board of the sea. They guide our voyage without controlling the waves, which toss for ever in spite of our ability to ride over them to our chosen ends. Sanity is a madness put to good uses; waking life is a dream controlled.
