And then, the moment a child is born, the face is alive. And the face communicates direct with both planes of primary consciousness. The moment a child is born, it begins to grope for the breast. And suddenly a new great circuit is established, the four poles all working at once, as the child sucks. There is the profound desirousness of the lower center of sympathy, and the superior avidity of the center of will, and at the same time, the cleaving yearning to the nipple, and the tiny curiosity of lips and gums. The nipple of the mother's breast is one of the great gates of the body, hence of the living psyche. In the nipple terminate vivid nerves which flash their very powerful vibrations through the mouth of the child and deep into its four great poles of being and knowing. Even the nipples of the man are gateways to the great dynamic flow: still gateways. Touch, taste, and smell are now active in the baby. And these senses, so-called, are strictly sensations. They are the first term of the child's mental knowledge. And on these three _cerebral_ reactions the foundation of the future mind is laid. The moment there is a perfect polarized circuit between the first four poles of dynamic consciousness, at that moment does the mind, the terminal station, flash into cognition. The first cognition is merely sensation: sensation and the remembrance of sensation being the first element in all knowing and in all conception. The circuit of touch, taste, and smell must be well established, before the eyes begin actually to see. All mental knowledge is built up of sensation and of memory. It is the continually recurring sensation of the touch of the mother which forms the basis of the first conception of the mother. After that, the gradually discriminated taste of the mother, and scent of the mother. Till gradually sight and hearing develop and largely usurp the first three senses, as medium of correspondence and of knowledge. And while, of course, the sensational _knowledge_ is being secreted in the brain, in some much more mysterious way the living individuality of the child is being developed in the four first nuclei, the four great nerve-centers of the primary field of consciousness and being. As time goes on, the child learns to see the mother. At first he sees her face as a blur, and though he knows her, knows her by a direct glow of communication, as if her face were a warm glowing life-lamp which rejoiced him. But gradually, as the circuit of touch, taste, and smell become powerfully established; gradually, as the individual develops in the child, and so retreats towards isolation; gradually, as the child stands more immune from the mother, the circuit of correspondence extends, and the eyes now communicate across space, the ears begin to discriminate sounds. Last of all develops discriminate hearing.
