Finally, in subtle ways, the influence of art, while remaining indirect, may affect practical action in a more concrete fashion. For silently, unobtrusively, when constantly attended to, a work of art will transform the background of values out of which action springs. The beliefs and sentiments expressed will be accepted not for the moment only, aesthetically and playfully, but for always and practically; they will become a part of our nature. The effect is not merely to enlarge the scope of our sympathies by making us responsive, as all art does, to every human aspiration, but rather to strengthen into resolves those aspirations that meet in us an answering need. This influence is especially potent during the early years of life, before the framework of valuations has become fixed. What young man nursed on Shelley's poetry has not become a lover of freedom and an active force against all oppression? But even in maturer years art may work in this way. One cannot live constantly with the "Hermes" of Praxiteles without something of its serenity entering into one's soul to purge passion of violence, or with Goethe's poetry without its wisdom making one wise to live. The effect is not to cause any particular act, but so to mold the mind that every act performed is different because of this influence. I would compare this influence to that of friends. Friends may, of course, influence conduct directly and immediately through advice and persuasion, but that is not the most important effect of their lives. More important is the gradual diffusion of their attitudes and the enlightenment following their example. Through living their experiences with them, we come to adopt their valuations as our own; by observing how they solve their problems, we get suggestions as to how to solve ours. Art provides us with a companionship of the imagination, a new friendship. The sympathetic touch with the life there expressed enlarges our understanding of the problems and conditions of all life, and so leads to a freer and wiser direction of our own. On the one hand new and adventurous methods of living are suggested, and on the other hand the eternal limits of action are enforced.
