“In sculpture the projection of the fasciculi must be accentuated, the foreshortening forced, the hollows deepened; sculpture is the art of the hole and the lump, not of clear, well-smoothed, unmodelled figures. Ignorant people, when they see close-knitted true surfaces, say that 'it is not finished.' No notion is falser than that of finish unless it be that of elegance; by means of these two ideas people would kill our art. The way to obtain solidity and life is by work carried out to the fullest, not in the direction of achievement and of copying détails, but in that of truth in the successive schemes. The public, perverted by académie préjudices, confounds art with neatness. The simplicity of the 'École' is a painted cardboard ideal, A cast from life is a copy, the exactest possible copy, and yet it has neither motion nor eloquence. Art intervenes to exaggerate certain surfaces, and also to fine down others. In sculpture everything depends upon the way in which the modelling is carried out with a constant thought of the main line of the scheme, upon the rendering of the hollows, of the projections and of their connections; thus it is that one may get fine lights, and especially fine shadows that are not opaque. Everything should be emphasised according to the accent that it is desired to render, and the degree of amplification is personal, according to the tact and the temperament of each sculptor; and for this reason there is no transmissible process, no studio recipe, but only a true law. I see it in the antique and in Michael Angelo. To work by the profiles, in depth not by surfaces, always thinking of the few geometrical forms from which all nature proceeds, and to make these eternal forms perceptible in the individual case of the object studied, that is my criterion. That is not idealism, it is a part of the handicraft. My ideas have nothing to do with it but for that method; my Danaids and my Dante figures would be weak, bad things. From the large design that I get your mind deduces ideas.”
