(_ββ_) And generally it is obvious that painting, for the reason that its function is to accept as its content the wealth of soul-life in all its detail, is, to a yet greater extent than sculpture, unable to rest satisfied with that repose on itself which is without defined situation and the conception of a character taken by itself and alone simply. It is bound to make the effort to exhibit such self-subsistency and its content in specific situation, variety, and distinction of character viewed in their mutual relations and in association with their environment. It is, in fact, just this departure from purely eclectic and traditional types, from the architectonic composition of figures and the statuesque mode of conception; it is just this liberation from all that is devoid of movement and action, this striving after a living human expression, a characteristic individuality; it is this investment of a content with all the detail of the ideal and external condition that affects it which constitutes the advance of the art, in virtue of which it secures its own unique point of view. Consequently to painting as to no other plastic art is it not merely permitted, but it is even required from it, that it should unfold dramatic realization, and by the composition of its figures display their activity in a distinctly emphasized situation.
(_γγ_) And, in the _third_ place, closely connected with this absorption in the complete wealth of existing life and the dramatic movement of circumstance and character, we are aware of the importance which is increasingly attached, both in conception and execution, to the individuality and the vital wealth of the colour aspect of all objects, in so far as in painting we attain to the supremest effects of vital truth which are capable of being expressed purely by colour.
This magical result of appearance can, however, be carried to such a pitch, that in contrast to it the exhibition of content becomes a matter of indifference, and painting tends to pass over, in the mere charm and perfume of its colour tones, and the contrast, fusion, and play of their harmonies, into the art of music, precisely as sculpture, in the elaboration of its reliefs, tends to associate itself with painting.
