"Let us look at a Dutch interior and at an interior painted by an artist of the present day. The latter no longer touches us, because it does not possess the qualities of depth and volume, the science of distances. The artist who paints it does not know how to reproduce a cube. An interior by Van der Meer is a cubic painting. The atmosphere is in it and the exact volume of the objects ; the place of these objects has been respected, the modem painter places them, arranges them as models. The Dutchmen did not touch them, but set themselves to render the distances that separated them, that is, the depth. And then, if I go so far as to say that cubic truth, not appearance, is the mistress of things, if I add that the sight of the plains and woods and country views gives me the principle of the plans that I employ on my statues, that I feel cubic truth everywhere, and that plan and volume appear to me as laws of all life and ail beauty, will it be said that I am a symbolist, that I generalise, that I am a metaphysician ? It seems to me that I have remained a sculptor and a realist. Unity oppresses and haunts me."
