Objects, like words, have a meaning; and the true artist is the interpreter of this language, which he can only do by knowing its application to a thousand other objects in a thousand other situations. Thus the eye is too blind a guide of itself to distinguish between the warm or cold tone of a deep blue sky, but another sense acts as a monitor to it, and does not err. The colour of the leaves in autumn would be nothing without the feeling that accompanies it; but it is that feeling that stamps them on the canvas, faded, seared, blighted, shrinking from the winter’s flaw, and makes the sight as true as touch— ‘And visions, as poetic eyes avow, Cling to each leaf and hang on every bough.’ The more ethereal, evanescent, more refined and sublime part of art is the seeing nature through the medium of sentiment and passion, as each object is a symbol of the affections and a link in the chain of our endless being. But the unravelling this mysterious web of thought and feeling is alone in the Muse’s gift, namely, in the power of that trembling sensibility which is awake to every change and every modification of its ever-varying impressions, that, ‘Thrills in each nerve, and lives along the line.’ This power is indifferently called genius, imagination, feeling, taste; but the manner in which it acts upon the mind can neither be defined by abstract rules, as is the case in science, nor verified by continual unvarying experiments, as is the case in mechanical performances. The mechanical excellence of the Dutch painters in colouring and handling is that which comes the nearest in fine art to the perfection of certain manual exhibitions of skill. The truth of the effect and the facility with which it is produced are equally admirable. Up to a certain point, every thing is faultless. The hand and eye have done their part. There is only a want of taste and genius. It is after we enter upon that enchanted ground that the human mind begins to droop and flag as in a strange road, or in a thick mist, benighted and making little way with many attempts and many failures, and that the best of us only escape with half a triumph. The undefined and the imaginary are the regions that we must pass like Satan, difficult and doubtful, ‘half flying, half on foot.’ The object in sense is a positive thing, and execution comes with practice.
