For his faith at root is a very simple one: the love of beauty and the expression of it; only beauty with him is one of essence and significance, quite removed from any literary allusiveness, and as far as possible expressed by means which are solely the products of brush or etching needle, sensation and method approximating as much as may be to the exclusively abstract ones of music. He cannot escape the concrete altogether and must often use as vehicles of expression things to which the dictionary assigns terms, and to which the association of memory and ideas has given a verbal significance. But even in using these he feels such significance extraneous, and subordinates it as far as possible to the special æsthetic significance of the pictorial art. It is the meaning that these things have for the artist’s peculiar vision that he tries to keep free from other allusion--abstract. It is not the object before him for the time being that is worth his consideration, but the enjoyment of the purely æsthetic impression of it aroused in his own mind, of which he seeks to express the essence in his picture. It is a theory of art all but too subtle for human nature’s daily food; in a world in which we are continually confusing cause and effect, the object with the subject, the source of our enjoyment with the enjoyment itself; a theory quite intolerable when exploited by a mediocre painter, or by a facile painter of mediocre mind; only, perhaps, so acceptable in Whistler’s case, because it is essentially a product of his own unique originality. It was his craving for abstract expression as well as for abstract sensation that led to his symphonies; and the storm of abuse and ridicule which they aroused gave him, no doubt, a keener relish for such studies. It would be too much to say that any of them were done deliberately to mystify the public; but that he found a sly relish in the mystification is most probable, and one may believe that some of these, to him only experiments in the record of impressions, were exhibited with the Satanic purpose of infuriating a public, so enamoured of the “finished picture.” Today, however, these studies are applauded, and Whistler is probably as contemptuous of the undiscriminating approval as of the indiscriminate abuse. For really their vogue is as open to suspicion as would be a vogue of Bach. In their lack of any graspable theme and in their delicately elaborated orchestration of tone they can be appreciated, priced, that is to say, at their proper worth, only by those whose sense of colour is very cultivated; nor even, perhaps, by all of them, for these impressions are so personal to their author that they must always mean more and otherwise to him than to others.
