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.
