(_β_) Conversely, however, the art of painting, as we have seen, ought to advance further than this exclusive absorption in the ideal and infinite content of man's soul-life; its function is equally to assert the subsistency and freedom of detail, which however incidental it may be, contributes to the environment and background of the work. In this advance from the profoundest seriousness to the objective features of independent detail it is bound to force its way to the extreme articulation of the purely phenomenal, where any and every content is a matter of indifference, and artistic illusion in a realistic sense is the main interest. In such a type of art we find depicted for us the most fugitive aspect of the sky, the time of day, the lighting up of the woods, the gleam and reflection of the clouds, waves, lakes, streams, the shimmer and glitter of wine in the glass, the glance of the eye, and every conceivable look and smile of the human countenance. Painting in such cases moves from the idealistic standpoint to that of living reality, whose phenomenal effect it mainly seeks to reproduce by means of accuracy in the execution of every bit of detail[248]. Yet this effort is no mere assiduity of elaboration, but a real exercise of genuine talent, which strives to present every kind of detail in its independent perfection, and yet retain the whole composition in unity and fusion, and this can only be done by the finest art. In such work the vital force of the realistic appearance thus secured tends to be more near to the artist's aim than the Ideal; and it is precisely this kind of art, as I have already found occasion to remark, which raises, as no other, controversial points over the significance of the Ideal and Nature. No doubt it is very possible to blame the use of the most elaborate technique in subjects of little importance by themselves as mere extravagance; yet there is no real reason for rejecting such material, and it is precisely of that kind which ought to be treated in this way by art, and be permitted to keep every conceivable subtlety and refinement of surface appearance that it possesses.
