Our intellectual tread will be firmer if we define the imagination and consider its uses. The soul is a city; and the external senses are gateways through which sweep all the caravans of truth and beauty. Through the eye gate pass all faces, cities and landscapes. Through the ear gate pass all sweet sounds. But when the facts of land and sea and sky have reported themselves to the soul, reason sweeps these intellectual harvests into the granary of memory for future sowing. But these harvests must be arranged. In the Orient the merchant who keeps a general store puts the swords and spears upon one shelf; the tapestries and rugs upon another; the books and manuscripts upon a third; and each thing has its own shelf and drawer. So judgment comes in to sort knowledges, and puts things useful into one intellectual shelf, things beautiful upon another shelf, and puts things true apart by themselves. Afterward when the under-servant, called reason, has accumulated the materials, when memory has taken care of them, and judgment has classified all, then the constructive imagination comes in to create new objects. Working in iron and steel, the imagination of Watt organizes an engine; working midst the colors beautiful, the imagination paints pictures; working upon marble it carves statues; working in wood and stone it rears cathedrals; working in sound it creates symphonies; working with ideas it fashions intellectual systems; working in morals it constructs ethical principles; working toward immortality, it bids all cooling streams, fruitful trees, sweet sounds, all noble friendships, report themselves beyond the grave. For faith itself is but the imagination allied with confidence that God is able to realize man's highest ideals. Imagination therefore is a prophet. It is a seer for the soul. It toils as artist and architect and creator. It plants hard problems as seeds, rears these germs into trees, and from them garners the ripe fruit. It wins victory before battles are fought. Without it, civilization would be impossible. What we call progress is but society following after and realizing the visions, plans and patterns of the imagination. Now our busy, bustling age is inclined to under-estimate the imagination. Men cavil at castle-building. The pragmatist jeers at reveries. Men believe in stores, and goods in them; in factories, and wealth by them; men believe in houses and horses, but not in ideals. Nevertheless, thoughts and dreams are the stuff out of which towns and cities are builded. We may despise the silent dreamer, but in the last analysis he appears the real architect of states! Immeasurable the practical power of the vision faculty! The heroes of yesterday have all been sustained--not by swords and guns, but by the sight of the invisible!
