“ But even from the point of view of the true visual perception (if there is such a thing) that modern art has heard so much talk of, the copying of the retina picture is not so great a success. The impression carried away from a scene that has moved us is not its complete visual aspect. Only those things that are significant to the felt impression have been retained by the mind; and if the picture is to be a true representation of this, the significant facts must be sorted out from the mass of irrelevant matter and presented in a lively manner. ”
