Nor can you regard these strands themselves as ultimate. As the most prudent of logicians might venture to deduce from a skein of wool the probable existence of a sheep; so you, from the raw stuff of perception, may venture to deduce a universe which transcends the reproductive powers of your loom. Even the camera of the photographer, more apt at contemplation than the mind of man, has shown us how limited are these powers in some directions, and enlightened us as to a few of the cruder errors of the person who accepts its products at face-value; or, as he would say, believes his own eyes. It has shown us, for instance, that the galloping race-horse, with legs stretched out as we are used to see it, is a mythical animal, probably founded on the mental image of a running dog. No horse has ever galloped thus: but its real action is too quick for us, and we explain it to ourselves as something resembling the more deliberate dog-action which we have caught and registered as it passed. The plain man's universe is full of race-horses which are really running dogs: of conventional waves, first seen in pictures and then imagined upon the sea: of psychological situations taken from books and applied to human life: of racial peculiarities generalised from insufficient data, and then "discovered" in actuality: of theological diagrams and scientific "laws," flung upon the background of eternity as the magic lantern's image is reflected on the screen. The coloured scene at which you look so trustfully owes, in fact, much of its character to the activities of the seer: to that process of thought--concept--cogitation, from which Keats prayed with so great an ardour to escape, when he exclaimed in words which will seem to you, according to the temper of your mind, either an invitation to the higher laziness or one of the most profound aspirations of the soul, "O for a life of sensations rather than thoughts!" He felt--as all the poets have felt with him--that another, lovelier world, tinted with unimaginable wonders, alive with ultimate music, awaited those who could free themselves from the fetters of the mind, lay down the shuttle and the weaver's comb, and reach out beyond the conceptual image to intuitive contact with the Thing.
