The imperfect offices of prayer and praise,

His mind was a thanksgiving to the power

That made him; it was blessedness and love.”

As we read such a passage, the thought involuntarily arises, What if the said youth, instead of being a nursling of nature among the hills of Atholl, had been college-bred, and crammed with all the ’ologies which Physical Science now teaches, would he still have had the same elevated joy in presence of that spectacle? It is the old question which Plato asked, and which many since have asked down to our own time. In 1842 Haydon wrote to Wordsworth, recalling a dinner-party which took place many years before at the painter’s house: “Don’t you remember Keats proposing ‘Confusion to the memory of Newton,’ and upon your insisting on an explanation before you drank it, his saying, Because he destroyed the poetry of the rainbow by reducing it to a prism?” Suppose the Atholl shepherd lad had been an optician, and understood all the laws of light by which the effulgent hues of sunrise were elicited; suppose, further, that he had been an astronomer, and as he saw the sunrise had begun to reflect, It is not the sun that I see rising, but it is the earth that is rotating on her own axis, and now turning her side toward the sun, that causes all that I now see; and that axis is not vertical, but slants obliquely to the plane of its orbit,—supposing these, and a hundred other truths, which Physical Astronomy teaches, had come into his mind, would he still have had that sublime joy?

Or suppose, again, he had been a geologist, and, as he gazed over the mountain ridges, had begun to think of them as a record of commotions that took place in far-back geological eras, and to reflect how the stratified layers of which these mountains are composed had been formed by the slime deposited at the bottom of a long since vanished sea; how they had been upheaved by the action of subterranean forces; how some of the great depressions which we call valleys, or those rents in the mountains, now filled by sea-lochs, had been caused by the cracking of the earth’s crust, while it was still a heated mass, glowing from the primeval fires; how other lesser glens and corries had been sculptured out of the solid earth by Nature’s graving tools, ice-wedges, glaciers, rain, and rivers,—in the presence of such scientific thoughts as these, what would become of the boy’s imaginative and devout ecstasy?

In answer, it may be said that whether the scientific man shall feel this spontaneous glow in the presence of the great spectacles of Nature or not, depends not on his scientific knowledge, but on his natural temperament, on the amount of soul there is in him, underlying his attainments. If he be so entirely the man of science, if the intellect has so entirely absorbed his being that he never gets beyond analyzing, comparing, and reasoning on the appearances he sees, then he will look without emotion on the grandest ongoings of Nature; he will see in them only a subject for investigation—nothing more. But if, as has often been the case, the physicist be a man not only of wide and accurate knowledge, but of large soul,—if his knowledge has become a part of him, has melted into his being, then his heart will be free to kindle and rejoice at the great things of Nature which he sees, as genuinely as the unreflecting child, the thoughtful peasant, or the most spontaneous poet.

As genuinely, but with a difference: the eye of the imaginative man of science will take in all that these others do, and more. His admiration will be fuller, larger, more instructed. The knowledge that has been gradually lodged in his mind, and become a part of it, will pass into his eye, and enable him to see, on whatever side of the Universe he looks, more complicated marvels, more wonderful correspondences.

“In Wonder,” says Coleridge, “all Philosophy began: in Wonder it ends: and Admiration fills up the interspace.” The last clause I should change thus,—and Investigation fills up the interspace. In the first Wonder and in the last the Philosopher and the Poet are akin to each other. Both wonder, both admire what they see, but this incipient wonder tends to different results. The unscientific poet, just like the child and the thoughtful peasant, wonders at the beauty that is in the face of Nature, and at its mystery, seeks no physical explanations of it, but reads its moral and spiritual meaning, and tries to utter it. The man of science equally begins with wonder at what he sees, but his wonder leads him on to seek for an explanation, to search for the laws which regulate the appearances, if haply he may find them.

Then comes the long interspace of toilsome labor, of painful analysis, of rigorous induction. Experiment, analysis, deductive and inductive reasoning, by which chiefly Science works, are intellectual acts quite distinct from imaginative intuition and emotion, and, in some degree, opposed to them. It cannot be that these distinct processes can be combined in one intellectual act. They can hardly go on in one mind at the same time. While a man is immersed in these scientific processes, they preclude the poetic vision for the time. For many men they scare away poetry from the world forever.

Not so with the largest, most sovereign minds of Science. Lesser men of dry or narrow minds may be so entangled in the meshes of their own understanding as never to escape from them, or may find more delight in the cleverness of their own explanations than in the wonderful things which they explain. But the larger minds, when they have done their work, emerge in time from the study and the laboratory, and look abroad with expanded vision and profounder reverence on that Universe, some small part only of which it has been given them to understand. Kepler, after he had discovered so far the laws of planetary motion, said that all that he had been able to do was to read a few of the thoughts of God. A short time before his death, Newton is reported to have said, and I give the oft-told story in the authentic words, “I do not know what I may appear to the world, but to myself I seem to have been only like a boy playing on the sea-shore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me.”[6] A lesson surely to all future investigators, and, as his latest biographer has said, “to those especially who have never even found the smoother pebble or the prettier shell.” These great men, so feeling, are in the attitude of philosophic wonder—wonder both at part of the ways of God which it has been given them to see, and at that vaster part which they feel to lie beyond their vision. These laws which they have discovered, what are they? whence come they? They know that they themselves did not make them, only attained to catch sight of them. They know too that the laws did not make themselves. They are beautiful in themselves and in their benign operation; they are wonderful in their origin and continuance. This is what those great discoverers felt. And when they stood on the utmost verge of their scientific knowledge, and looked from what they had been allowed to see out upon the great beyond, they were rapt into that mood of wonder, akin to awe, which is the very essence of Poetry. Had they, in addition to their great scientific insight, been endowed with the gift of poetic utterance to express the wonder which they felt, they might have left to the world a poem of scientific truth transfigured by the imagination, such as has never yet been uttered.
