The Lady of Shalott, sitting in her tower, looked into her magic mirror and saw the whole world go by,—monk, maiden, priest, knight, lady, and king. In the mirror of the imagination not only the world of to-day but the entire movement of human life moves before the eye as the throngs of living men move on the streets. For the imagination is the real magician, of whose marvels all simulated magic is but a clumsy and mechanical imitation. It is the real power, of which all material powers are very inadequate symbols. Rarely taken into account by teachers, largely ignored by educational systems and philosophies, it is the divinest of all the powers which men are able to put forth, because it is the creative power. It uses thought, but, in a way, it is greater than thought, because it builds out of thought that which thought alone is powerless to construct. It is, indeed, the essential element in great constructive thinking; for while we may have thoughts untouched by the imagination, one cannot think along high constructive lines without its constant aid. Isolated thoughts come unattended by it, but the thinking which issues in organised systems, in comprehensive interpretations of things and events, in those noble generalisations which have the splendour of the discovery of new worlds in them, in those concrete embodiments of idea which we call works of art, is conditioned on the use of the imagination. Plato’s Dialogues were fashioned by it as truly as Homer’s poems; Hegel’s philosophy was created by it as definitely as Shakespeare’s plays, and Newton and Kepler used it as freely as Dante or Rembrandt.
