From an artistic standpoint, nature is no model. It exaggerates, distorts, and leaves gaps. Nature is the accident.

Context

“But look at the result!—a mass of daubs, at best a piece of mosaic, in any case something heaped together, restless and garish. The Goncourts are the greatest sinners in this respect: they cannot put three sentences together which are not absolutely painful to the eye—the eye of the psychologist. From an artistic standpoint, nature is no model. It exaggerates, distorts, and leaves gaps. Nature is the accident. To study "from nature" seems to me a bad sign: it betrays submission, weakness, fatalism—this lying in the dust before trivial facts is unworthy of a thorough artist. To see what is—is the function of another order of intellects, the anti-artistic, the matter-of-fact One must know who one is.” source
