Gnostic Psychology recognizes that humanoids actually have three centers of intelligence within: an intellectual brain, an emotional brain, and a motor/instinctive/sexual brain. These are not physical brains; they are divisions of organized activity. Each one functions and operates independent of the others, and each one has a host of jobs and duties that only it can accomplish. Of course, in modern humanity the three brains are grossly out of balance and used incorrectly. See Revolutionary Psychology by Samael Aun Weor.
