It is like the Greek fire used in ancient warfare, which burnt unquenched beneath the water; or like the weeds which, when you have extirpated them in one place, are sprouting forth vigorously in another spot, at the distance of many hundred yards; or, to use the metaphor of St. James, it is like the wheel which catches fire as it goes, and burns with fiercer conflagration as its own speed increases. [ F. W. Robertson ]

Poetry reveals to us the loveliness of nature, brings back the freshness of youthful feeling, revives the relish of simple pleasures, keeps unquenched the enthusiasm which warmed the springtime of our being, refines youthful love, strengthens our interest in human nature, by vivid delineations of its tenderest and softest feelings, and, through the brightness of its prophetic visions, helps faith to lay hold on the future life. [ Channing ]
