Another primate wrote that every primate infant goes through a stage of being chiefly concerned with bio-survival, i.e., food, i.e., Mommie’s Titty. He called this the Oral Stage. He said the infant next went on to a stage of learning mammalian politics, i.e., recognizing the Father (alpha-male) and his Authority and territorial demands. He called this, with an insight that few primates shared, the Anal Stage. This primate was named Freud. He had taken his own nervous system apart and examined its component circuits by periodically altering its structure with neurochemicals.
