Thus we see there is a poetic glow of wonder and emotion before Science begins its work; there is a larger, deeper, more instructed wonder when it ends. And either of these may naturally express itself in poetry, though the earlier wonder has done so far more frequently than the later. That the contemplation of the Universe does awaken this wonder in minds of the highest scientific order appears in the instances of Kepler and Newton. It has been shown in the case of an original discovery nearer our own day than either of these—I mean in that of Faraday. The following account of the imaginative delight which he felt in his scientific investigations I venture to quote from a very suggestive lecture of Mr. Stopford Brooke. “Nature and her contemplation, says Professor Tyndall, produced in him a kind of spiritual exaltation: his delight in a sunset or a thunderstorm amounted to ecstasy. Our subjects are so glorious, he says himself, that to work at them rejoices and encourages the feeblest, delights and contents the strongest. In this delight and enchantment he was always in the temper of the poet, and, like the poet, he continually reached that point of emotion which produces poetic creation. Once, after long brooding on the subject of force and matter, he saw, and I am sure suddenly, as a poet sees a song from end to end before he writes it down,—he saw, as if lit by a stream of sudden light, the whole of the Universe traversed by lines of force, and these lines in their ceaseless tremors producing light and radiant heat; and dashing forward on the trail of his ideas, and thrilled into creation by the emotion which he felt, declared that these lines were the lines of gravitating force, and that the gravitating force itself constituted matter; that is, he made force identical with matter. It was a speculation which abolished at a stroke the atomic theory and the notion of an ether. Of the possibility of the truth of this I am no judge,” says Mr. Stopford Brooke. “Faraday himself calls it the shadow of a speculation. But who does not see that it proceeded after the manner of poetry; that in it poetry and philosophy went hand in hand? It was one of those inspired, sudden guesses which come to the poet who writes of the soul, coming to the philosopher who writes of the universe. In the midst of unremitting work at details suddenly a vision of the glory of the sum of things flashed upon his sight.” CHAPTER IV. WILL SCIENCE PUT OUT POETRY?
