suggests questions of _how_ and _why_ which get their answers in some item obliging you to take fresh stock of the picture. What Is the meaning of the angels and evidently supernatural horseman in the foreground of Raphael's _Heliodorus?_ Your mind flies to the praying High Priest in the central recess of the temple, and in going backwards and forwards between him, the main group and the scattered astonished bystanders, you are effectually enclosed within the arches of that marvellous composition, and induced to explore every detail of its lovely and noble constituent shapes. The methods employed thus to keep the beholder's attention inside the work of art while suggesting things beyond it, naturally vary with the exact nature of the non-aesthetic task which has been set to the artist; and with the artist's individual endowment and even more with the traditional artistic formulae of his country and time: Raphael's devices in _Heliodorus_ could not have been compassed by Giotto; and, on the other hand, would have been rejected as "academic" by Manet. But whatever the methods employed, and however obviously they reveal that satisfactory form-contemplation is the one and invariable _condition_ as distinguished from the innumerable varying _aims,_ of all works of art, the Reader will find them discussed not as methods for securing attention to the shape, but as methods of employing that shape for some non-aesthetic purpose; whether that purpose be inducing you to drink out of a cup by making its shape convenient or suggestive; or inducing you to buy a particular commodity by branding its name and virtues on your mind; or fixing your thoughts on the Madonna's sorrows; or awaking your sympathy for Isolde's love tragedy. And yet it is evident that the artist who shaped the cup or designed the poster would be horribly disappointed if you thought only of drinking or of shopping and never gave another look to the cup or the poster; and that Perugino or Wagner would have died of despair if his suggestion of the Madonna's sorrows or of Isolde's love-agonies had been so efficacious as to prevent anybody from looking twice at the fresco or listening to the end of the opera. This inversion of the question is worth inquiring into, because, like the analogous paradox about the pictorial "realisation" of cubic existence, it affords an illustration of some of the psychological intricacies of the relation between Art and the Beautiful. This is how I propose to explain it.
