Certainly you will see many pictures that seem to justify this explanation. But as a rule they will not be examples of good painting. You remember our talk on texture. Well, only some textures are sleek and shiny and polished. So, if this whole picture is of that character, some of the textures must have suffered. Then again, life is not uniform, it does not show itself in all people and things in the same way. Therefore it is very likely that the uniform polish and precision of this picture has interfered with its expression of life. The whole thing is mechanical rather than vital.
