How can we make things beautiful, attractive, and desirable for us when they are not? And I rather think that in themselves they never are. Here we could learn something from physicians, when for example they dilute what is bitter or add wine and sugar to a mixture—but even more from artists who are really continually trying to bring off such inventions and feats.
Moving away from things until there is a good deal that one no longer sees and there is much that our eye has to add if we are still to see them at all; or seeing things around a corner and as cut out and framed; or to place them so that they partially conceal each other and grant us only glimpses of architectural perspectives; or looking at them through tinted glasses or in the light of the sunset; or giving them a surface and skin that is not really transparent—all this we should learn from artists while being wiser than they are in other matters.
For with them this subtle power usually comes to an end where art ends and life begins; but we want to be the poets of our life—first of all in the smallest, most everyday matters.
