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.
