well awake, the guidance which the artist gives him should be full and authoritative: the beholder's imagination must not be suffered to take its own way, or wander hither and thither; but neither must it be left at rest; and the right point of realization, for any given work of art, is that which will enable the spectator to complete it for himself, in the exact way the artist would have him, but not that which will save him the trouble of effecting the completion. So soon as the idea is entirely conveyed, the artist's labor should cease; and every touch which he adds beyond the point when, with the help of the beholder's imagination, the story ought to have been told, is a degradation to his work. So that the art is wrong, which either realizes its subject completely, or fails in giving such definite aid as shall enable it to be realized by the beholding imagination. § XXII. It follows, therefore, that the quantity of finish or detail which may rightly be bestowed upon any work, depends on the number and kind of ideas which the artist wishes to convey, much more than on the amount of realization necessary to enable the imagination to grasp them. It is true that the differences of judgment formed by one or another observer are in great degree dependent on their unequal imaginative powers, as well as their unequal efforts in following the artist's intention; and it constantly happens that the drawing which appears clear to the painter in whose mind the thought is formed, is slightly inadequate to suggest it to the spectator. These causes of false judgment, or imperfect achievement, must always exist, but they are of no importance. For, in nearly every mind, the imaginative power, however unable to act independently, is so easily helped and so brightly animated by the most obscure suggestion, that there is no form of artistical language which will not readily be seized by it, if once it set itself intelligently to the task; and even without such effort there are few hieroglyphics of which, once understanding that it is to take them as hieroglyphics, it cannot make itself a pleasant picture.
