"There are ambiguities in the art of painting but they are the ambiguities of a fine precision: the discovered fact of the image containing at the same time the reverberations of the unknown, the truly mysterious… I would take this further and add that painting is itself precise in its ideas. In the sense that the image is the idea in its purist form."
