Quite apart therefore from the convenience or not of the adjustments requisite for their ocular measurement, and apart even from the facility or difficulty of comparing and coordinating these measurements, certain shapes and elements of shape are made welcome to us, and other ones made unwelcome, by the sole working of Empathy, which identifies the modes of being and moving of lines with our own. For this reason meetings of lines which affect us as neither victory nor honourable submission nor willing cooperation are felt to be ineffectual and foolish. Lines also (like those of insufficiently tapered Doric columns) which do not rise with enough impetus because they do not seem to start with sufficient pressure at the base; oblique lines (as in certain imitation Gothic) which lose their balance for lack of a countervailing thrust against them, all these, and alas many hundreds of other possible combinations, are detestable to our feelings. And similarly we are fussed and bored by the tentative lines, the uncoordinated directions and impacts, of inferior, even if technically expert and realistically learned draughtsmen, of artists whose work may charm at first glance by some vivid likeness or poetic suggestion, but reveal with every additional day their complete insignificance as movement, their utter empathic nullity. Indeed, if we analyse the censure ostensibly based upon engineering considerations of material instability, or on wrong perspective or anatomical "out of drawing" we shall find that much of this hostile criticism is really that of empathic un-satisfactoriness, which escapes verbal detection but is revealed by the finger following, as we say (and that is itself an instance of empathy) the movement, the development of, boring or fussing lines.
Empathy explains not only the universally existing preferences with regard to shape, but also those particular degrees of liking which are matters of personal temperament and even of momentary mood (cf. p. 131). Thus Mantegna, with his preponderance of horizontals and verticals will appeal to one beholder as grave and reassuring, but repel another beholder (or the same in a different mood) as dull and lifeless; while the unstable equilibrium and syncopated rythm of Botticelli may either fascinate or repel as morbidly excited. And Leonardo's systems of whirling interlaced circles will merely baffle (the "enigmatic" quality we hear so much of) the perfunctory beholder, while rewarding more adequate empathic imagination by allowing us to live, for a while, in the modes of the intensest and most purposeful and most harmonious energy.
Intensity and purposefulness and harmony. These are what everyday life affords but rarely to our longings. And this is what, thanks to this strange process of Empathy, a few inches of painted canvas, will sometimes allow us to realise completely and uninterruptedly. And it is no poetical metaphor or metaphysical figment, but mere psychological fact, to say that if the interlacing circles and pentacles of a Byzantine floor-pattern absorb us in satisfied contemplation, this is because the modes of being which we are obliged to invest them with are such as we vainly seek, or experience only to lose, in our scattered or hustled existence.
CHAPTER XII
FROM THE SHAPE TO THE THING
SUCH are the satisfactions and dissatisfactions, impersonal and unpractical, we can receive, or in reality, give ourselves, in the contemplation of shape.
But life has little leisure for contemplation; it demands recognition, inference and readiness for active adaptation. Or rather life forces us to deal with shapes mainly inasmuch as they indicate the actual or possible existence of other groups of qualities which may help or hurt us. Life hurries us into recognising Things.
Now the first peculiarity distinguishing things from shapes is that they can occupy more or less cubic space: we can hit up against them, displace them or be displaced by them, and in such process of displacing or resisting displacement, we become aware of two other peculiarities distinguishing things from shapes: they have weight in varying degrees and texture of various sorts. Otherwise expressed, things have body, they exist in three dimensional space; while shapes although they are often aspects of things (say statues or vases) having body and cubic existence, shapes as shapes are two dimensional and bodiless.
So many of the critical applications of aesthetic, as well as of the historical problems of art-evolution are connected with this fact or rather the continued misunderstanding of it, that it is well to remind the Reader of what general Psychology can teach us of the perception of the Third Dimension. A very slight knowledge of cubic existence, in the sense of relief, is undoubtedly furnished as the stereoscope furnishes it, by the inevitable slight divergence between the two eyes; an even more infinitesimal dose of such knowledge is claimed for the surfaces of each eye separately. But whatever notions of three-dimensional space might have been developed from such rudiments, the perception of cubic existence which we actually possess and employ, is undeniably based upon the incomparably more important data afforded by locomotion, under which term I include even the tiny pressure of a finger against a surface, and the exploration of a hollow tooth by the tip of the tongue. The muscular adjustments made in such locomotion become associated by repetition with the two-dimensional arrangements of colour and light revealed by the eye, the two-dimensional being thus turned into the three-dimensional in our everyday experience. But the mistakes we occasionally make, for instance taking a road seen from above for a church-tower projecting out of the plain, or the perspective of a mountain range for its cubic shape, occasionally reveal that we do not really see three-dimensional objects, but merely infer them by connecting visual data with the result of locomotor experience. The truth of this commonplace of psychology can be tested by the experiment of making now one, now the other, colour of a floor pattern seem convex or concave according as we think of it as a light flower on a dark ground, or as a white cavity banked in by a dark ridge. And when the philistine (who may be you or me!) exclaims against the "out of drawing" and false perspective of unfamiliar styles of painting, he is, nine times out of ten, merely expressing his inability to identify two-dimensional shapes as "representing" three-dimensional things; so far proving that we do not decipher the cubic relations of a picture until we have guessed what that picture is supposed to stand for. And this is my reason for saying that visible shapes, though they may be aspects of cubic objects, have no body; and that the thought of their volume, their weight and their texture, is due to an interruption of our contemplation of shape by an excursion among the recollections of qualities which shapes, as shapes, cannot possess.
