So be it, there must be paroxysms, since there must be independence. Then the mother gets angry too. It affects her, though perhaps not as badly as it affects outsiders. Nothing acts more direct on the great primal nerve-centers than the screaming of an infant, this blind screaming negation of connections. It is the friction of irritation itself. Everybody is implicated, just as they would be if the air were surcharged with electricity. The mother is perhaps less affected because she understands primarily, or because she is polarized directly with the child. Yet she, too, must be angry, in her measure, inevitably. It is a blind, almost mechanistic effort on the part of the new organism to extricate itself from cohesion with the circumambient universe. It applies direct to the mother. But it affects everybody. The great centers of response vibrate with a maddening, sometimes unbearable friction. What centers? Not the great sympathetic plexus this time, but its corresponding voluntary ganglion. The great ganglion of the spinal system, the lumbar ganglion, negatively polarizes the solar plexus in the primal psychic activity of a human individual. When a child screams with temper, it sends out from the lumbar ganglion violent waves of frictional repudiation, extraordinary. The little back has an amazing power once it stiffens itself. In the lumbar ganglion the unconscious now vibrates tremendously in the activity of sundering, separation. Mother and child, polarized, are primarily affected. Often the mother is so _sure_ of her possession of the child that she is almost unmoved. But the child continues, till the frictional response is roused in the mother, her anger rises, there is a flash, an outburst like lightning. And then the storm subsides. The pure act of sundering is effected. Each being is clarified further into its own single, individual self, further perfected, separated. Hence a duality, now, in primal consciousness in the infant. The warm rosy abdomen, tender with chuckling unison, and the little back strengthening itself. The child kicks away, into independence. It stiffens its spine in the strength of its own private and separate, inviolable existence. It will admit now of no trespass. It is awake now in a new pride, a new self-assertion. The sense of antagonistic freedom is aroused. Clumsy old adhesions must be ruthlessly fused. And so, from the lumbar ganglion the fiery-tempered infant asserts its new, blind will.
