Now in what way, we ask, can form in painting give me a sensation of pleasure which differs from the ordinary sensations I receive from form? How is it that an object whose recognition in nature may have given me no pleasure, becomes, when recognised in a picture, a source of aesthetic enjoyment, or that recognition pleasurable in nature becomes an enhanced pleasure the moment it is transferred to art? The answer, I believe, depends upon the fact that art stimulates to an unwonted activity psychical processes which are in themselves the source of most (if not all) of our pleasures, and which here, free from disturbing physical sensations, never tend to pass over into pain. For instance: I am in the habit of realising a given object with an intensity that we shall value as 2. If I suddenly realise this familiar object with an intensity of 4, I receive the immediate pleasure which accompanies a doubling of my mental activity. But the pleasure rarely stops here. Those who are capable of receiving direct pleasure from a work of art, are generally led on to the further pleasures of self-consciousness. The fact that the psychical process of recognition goes forward with the unusual intensity of 4 to 2, overwhelms them with the sense of having twice the capacity they had credited themselves with: their whole personality is enhanced, and, being aware that this enhancement is connected with the object in question, they for some time after take not only an increased interest in it, but continue to realise it with the new intensity. Precisely this is what form does in painting: it lends a higher coefficient of reality to the object represented, with the consequent enjoyment of accelerated psychical processes, and the exhilarating sense of increased capacity in the observer. (Hence, by the way, the greater pleasure we take in the object painted than in itself.) And it happens thus. We remember that to realise form we must give tactile values to retinal sensations. Ordinarily we have considerable difficulty in skimming off these tactile values, and by the time they have reached our consciousness, they have lost much of their strength. Obviously, the artist who gives us these values more rapidly than the object itself gives them, gives us the pleasures consequent upon a more vivid realisation of the object, and the further pleasures that come from the sense of greater psychical capacity. Furthermore, the stimulation of our tactile imagination awakens our consciousness of the importance of the tactile sense in our physical and mental functioning, and thus, again, by making us feel better provided for life than we were aware of being, gives us a heightened sense of capacity. And this brings us back once more to the statement that the chief business of the figure painter, as an artist, is to stimulate the tactile imagination.
