The opinion most widely accepted is that the artist creates beauty; that in some mysterious way, by virtue of a special gift, he does actually evolve from within his own consciousness forms of grace and loveliness; that however deeply the artist sinks himself in nature, art yet remains intensely individual; that in representing nature he adds to that which he secures from nature a personal quality which becomes the most important part of the work. This is the theory of art accepted very generally, but it is not supported by evidence. The main purpose of this writing is, in fact, to establish by the evidence of the men who are quoted that their reliance has been solely upon nature and their success in exact proportion to their knowledge of nature and their ability to portray her predominant qualities. Let me repeat, however, that the ability to see and understand nature is dependent upon mental power. The man of limited mental power will see little; the one of great power will see much. The latter will apprehend the subtle, elusive qualities in a way impossible to the former. This, I know, is equivalent to saying that the great artist must bring to his task a great mind. This assumption is quite correct. A great mind is that power which is vaguely described as genius; it is what enables men to accomplish great things in every field of human endeavor. The question, therefore, is not whether the great artist possesses superior power, but rather how important are the inevitable traces of personal predilection or technical manner revealed in nearly all works of art as compared with the truthful presentation of the fundamental qualities the artist has discovered and undertaken to represent. Let us examine this phase of the question more fully. A painting by Corot for instance bears, first, the evidence of Corot’s choice of subject. That which appealed to him in nature he painted. The kind of thing he loved, the phase of nature he chose, unquestionably bore evidence of his personal temperament or predilection. By this he expressed his personal taste, his discriminating judgment, himself, in fact. If the artist be a man of gentle and sensitive quality, he will select for representation, as Corot did, a phase of nature which is in accord with his feeling.
