From this center, too, he learns to use his legs. The motion of walking, like the motion of breathing, is twofold. First, a sympathetic cleaving to the earth with the foot: then the voluntary rejection, the spurning, the kicking away, the exultance in power and freedom. From the upper voluntary center the child watches persistently, wilfully, for the attention of the mother: to be taken notice of, to be caressed, in short to exist in and through the mother's attention. From this center, too, he coldly refuses to notice the mother, when she insists on too much attention. This cold refusal is different from the active rejection of the lower center. It is passive, but cold and negative. It is the great force of our day. From the ganglion of the shoulders, also, the child breathes and his heart beats. From the same center he learns the first use of his arms. In the gesture of sympathy, from the upper plane, he embraces his mother with his arms. In the motion of curiosity, or interest, which derives from the thoracic ganglion, he spreads his fingers, touches, feels, explores. In the motion of rejection he drops an undesired object deliberately out of sight. And then, when the four centers of what we call the first _field_ of consciousness are fully active, then it is that the eyes begin to gather their sight, the mouth to speak, the ears to awake to their intelligent hearings; all as a result of the great fourfold activity of the first dynamic field of consciousness. And then also, as a result, the mind wakens to its impressions and to its incipient control. For at first the control is non-mental, even non-cerebral. The brain acts only as a sort of switchboard. The business of the father, in all this incipient child-development, is to stand outside as a final authority and make the necessary adjustments. Where there is too much sympathy, then the great voluntary centers of the spine are weak, the child tends to be delicate. Then the father by instinct supplies the roughness, the sternness which stiffens in the child the centers of resistance and independence, right from the very earliest days. Often, for a mere infant, it is the father's fierce or stern presence, the vibration of his voice, which starts the frictional and independent activity of the great voluntary ganglion and gives the first impulse to the independence which later on is life itself. But on the other hand, the father, from his distance, supports, protects, nourishes his child, and it is ultimately on the remote but powerful father-love that the infant rests, in a rest which is beyond mother-love. For in the male the dominant centers are naturally the volitional centers, centers of responsibility, authority, and care.
