However much the artistic impulse may become differentiated with the progress of culture, its innermost nature will always remain the same. However complex its manifestations, their aim is always to secure a faithful response to an overmastering feeling. The more accomplished the work of art, the more its creator will become independent of the chance audience, which by its sympathetic expression produces an enhancing retroaction on his feeling. He learns to give his mental states an embodiment which facilitates their reproduction in wider surroundings. Thus the expressional impulse directs him to place himself in sympathetic rapport with a fictitious public. He creates, that is to say, expresses himself, for an ideal spectator,—for posterity or for himself. With a proud indifference to his most immediate social environment, he may thus consider his own production as perfectly exempt of any social motivation. The aphorism of Mill, “All poetry is a soliloquy,” would no doubt be accepted by many of the most eminent poets. But the psychological observer cannot help remarking that in such soliloquies the ego serves as a substitute for an external public. The artist has in a sense a double capacity; and artistic creation in solitude may be always explained by the fact that the creator exists also as his own spectator. The production of even the most individualistic and most isolated artists can therefore be explained only by sociological considerations. And the same is the case with those artists who work only for posterity. It would be wrong to say that art in any one of its higher manifestations aims at transmitting a feeling. Its purpose is far rather an immortalisation. But this very desire to perpetuate a mental state, this desire which constrains the artist to strive indefatigably for the attainment of a form, capable of imparting to all men of every country and every age the same enhancement and the same rapture which he has himself experienced—this highest manifestation of the expressional impulse—can be fully explained only by reference to the enhancing and relieving power of social expression. In whatever light the art-impulse may appear to the reflecting consciousness of the producing artist, this is the only consistent interpretation at which we can arrive by an examination of the artistic activity on psychological grounds.
