I confess, it strikes me as a self-evident truth that variety or contrast is as essential a principle in art and nature as uniformity, and as necessary to make up the harmony of the universe and the contentment of the mind. Who would destroy the shifting effects of light and shade, the sharp, lively opposition of colours in the same or in different objects, the streaks in a flower, the stains in a piece of marble, to reduce all to the same neutral, dead colouring, the same middle tint? Yet it is on this principle that Sir Joshua would get rid of all variety, character, expression, and picturesque effect in forms, or at least measure the worth or the spuriousness of all these according to their reference to or departure from a given or average standard. Surely, nature is more liberal, art is wider than Sir Joshua’s theory. Allow (for the sake of argument) that all forms are in themselves indifferent, and that beauty or the sense of pleasure in forms can therefore only arise from customary association, or from that middle impression to which they all tend: yet this cannot by the same rule apply to other things. Suppose there is no capacity in form to affect the mind except from its corresponding to previous expectation, the same thing cannot be said of the idea of power or grandeur. No one can say that the idea of power does not affect the mind with the sense of awe and sublimity. That is, power and weakness, grandeur and littleness, are not indifferent things, the perfection of which consists in a medium between both. Again, expression is not a thing indifferent in itself, which derives its value or its interest solely from its conformity to a neutral standard. Who would neutralise the expression of pleasure and pain? Or say that the passions of the human mind, pity, love, joy, sorrow, &c. are only interesting to the imagination and worth the attention of the artist, as he can reduce them to an equivocal state which is neither pleasant nor painful, neither one thing nor the other? Or who would stop short of the utmost refinement, precision, and force in the delineation of each? Ideal expression is not neutral expression, but extreme expression. Again, character is a thing of peculiarity, of striking contrast, of distinction, and not of uniformity. It is necessarily opposed to Sir Joshua’s exclusive theory, and yet it is surely a curious and interesting field of speculation for the human mind. Lively, spirited discrimination of character is one source of gratification to the lover of nature and art, which it could not be, if all truth and excellence consisted in rejecting individual traits. Ideal character is not common-place, but consistent character marked throughout, which may take place in history or portrait. Historical truth in a picture is the putting the different features of the face or muscles of the body into consistent action. The _picturesque_ altogether depends on particular points or qualities of an object, projecting as it
