Imagination that compares and contrasts with what is around as well as what is better and worse is the living power and prime agent of all human perception judgement and emotional reaction.
Samuel Taylor ColeridgeA grief without a pang, void, dark and drear, A drowsy, stifled, unimpassioned grief, Which finds no natural outlet or relief, In word, or sigh, or tear.
Samuel Taylor ColeridgeHe knows well the evening star, and once when he awoke, in a most distressful mood (some inward pain had made up that strange thing, an infant's dream), I hurried with him to our orchard plot, and he beheld the moon, and hushed at once. Suspends his sobs and laughs most silently. While his fair eyes, that swam with undropped tears, did glitter in the yellow moonbeam.
