Inquiry concerning the complex movements of inner imitation is not yet past its opening stages, but so much seems to be established—namely, that by it are called forth movement and postural sensations (especially those of equilibrium), light muscular innervation, together with visual and respiratory movement, all of which are of great importance. Movements of the eyes have been given special attention by R. Vischer,[605] sensations of rest by Couturat.[606] Wundt has made eye movements of general psychological interest, and S. Stricker[607] has attempted to do the same for the muscular sensations called forth by the central impulses (at the present stage, including principally tactile sensations of the skin, as well as muscular and joint sensations). Intensely interesting is the article by Vernon Lee and Anstruther-Thomson on beauty and its contrary,[608] which quotes a number of observers who, as much from practice as from the possession of exceptional gifts, far transcend the limits attained by the average man in self-observation. Couturat and Stricker advance the idea that such movement processes, so far as they depend on mild muscular contraction, are due to the imitative impulse. Before adducing some examples, I must venture on one more observation. It is not, of course, to be assumed that such external movements are necessarily genuine copies of sense-perceptions. In the psychological treatment of eye movements, for example, sufficient caution has not been exercised, and consequently a false standard has arisen, transcending the facts. Here we shall find a comparison with external dramatic imitation play of great value, bearing in mind that the result of the latter is a symbol, not a counterpart. When a boy has to cut off his comrade’s head in dramatic play, a very soft blow with a stick is sufficient to indicate execution with the sword of justice, and in the same way and degree the movement of which we are speaking may be symbolic. Suppose a man fancying a huge spiral imprinted on the wall in front of him. If he remembers the motor processes he can reproduce them at will; little movements of the eyes, little tensions of the neck muscles and in the throat, together with breathing movements, are useful and (at least in my own case) even indispensable, and yet there is no really spiral motion—the symbol is sufficient.[609]
