De Witt H. Parker, The Principles of Aesthetics
“ In the first place, the color of the material is expressive. The black and gold of bronze have a depth and intensity, the whiteness of marble a coldness, clarity, and, serenity, inescapable. The weight and hardness, or lightness and softness, of the material, also count. If people do not feel the expressiveness of these qualities directly, they nevertheless do feel it indirectly, whenever they appreciate the superior fitness of marble and bronze for the embodiment of the heroic and supernatural, and of the light and fragile porcelain for the more fleeting and trivial phases of life. ”
