The first thing to remark is, that in the presence of Nature the poet and the man of science are alike observers. But in respect of time the poet has the precedence. Long before the botanist had applied his microscope to the flower, or the geologist his hammer to the rock, the poet’s eye had rested upon these objects, and noted the beauty of their lineaments. The poets were the first observers, and the earliest and greatest poets were the most exact and faithful in their observations. In the Psalms of Israel and in the Poems of Homer how many of the most beautiful and affecting images of Nature have been seized and embalmed in language which for exactness can not be surpassed, and for beauty can never grow obsolete! Indeed, fidelity to the truth of Nature, even in its minutest details, may be almost taken as a special note of the higher order of poets. It is not Homer but Dryden who to express the silence of night makes the drowsy mountains nod. It is a vulgar error which supposes that it is the privilege of imagination to absolve the poet from the duty of exact truth, and to set him free to make of Nature what he pleases. True imagination shows itself by nothing more than by that exquisite sensibility to beauty which makes it love and reverence Nature as it is. It feels instinctively that “He hath made everything beautiful in his time;” therefore it would not displace a blade of grass nor neglect the veining of a single leaf. Of course, from the touch of a great poet, the commonest objects acquire something more than exactness and truth of detail; they become forms of beauty, vehicles of human sentiment and emotion. But before they can be so used, fidelity to fact must first be secured. They cannot be made symbols of higher truth unless justice has first been done to the truth of fact concerning them. Hence it is that the works of the great poets of all ages are very repositories in which the features and ever-changing aspects of the outward world are rendered with the most loving fidelity and “vivid exactness.” This is one very delicate service which genuine poets have done to their fellow-men. They have by an instinct of their own noted the appearance of earth and sky, and kept alive the sense of their beauty during long ages when the world was little heedful of these things. How many are there who would own that there are features in the landscape, wild-flowers by the way-side, tender lights in the sky, which they would have passed forever unheeded, had not the remembered words of some poet awakened their eye to look on these things and to discern their beauty! Who ever now sees the “wee, modest, crimson-tipped flower,” and notes the peculiar coloring of the petals, without a new feeling of beauty in the flower itself, and of the added beauty it has received since the eye of Burns dwelt so lovingly upon it!
