not permitted to turn away

First, artistic perception had to overcome itself to the point of realizing that even something horrible, something that seems no more than disgusting, is, and shares the truth of its being with everything else that exists. Just as the creative artist is not permitted to choose, neither is he permitted to turn his back on anything: a single refusal, and he is cast out of the state of grace and becomes sinful all the way through. (Paris, 1907)
