“The attention given to the side of the head which has received the injury, in connection with a specific reference to the side of the body nervously affected, is in itself evidence that in this case the ancient surgeon was already beginning observations on the localization of functions in the brain.”

“The seat of consciousness and intelligence was from the earliest times regarded by the Egyptians as both the heart and the bowels or abdomen. Our surgeon, however, has observed the fact that injuries to the brain affect other parts of the body, especially in his experience the lower limbs. He notes the drag or shuffle of one foot, presumably the partial paralysis resulting from a cranial wound, and the ancient commentator carefully explains the meaning of the obsolete word used for "shuffle.”

“Here we see the word "brain" occurring for the first time in human speech, as far as it is known to us; and in discussing injuries affecting the brain, we note the surgeon's effort to delimit his terms as he selects for specialization a series of common and current words to designate three degrees of injury to the skull indicated in modern surgery by the terms "fracture", "compound fracture," and "compound comminuted fracture," all of which the ancient commentator carefully explains.”

“The combination of the Main brain with its central nervous system, and the ancient Animal Brain with its somatic, enteric nervous system in the inner body—in the gut—and the constant dialog between them provides a self-correcting feedback system, which regulates the behavioral qualities of the organism when consciously cultivated—preferably in early youth.”

“With him everything is a test, affection is measured, that given weighed against that which has been received, and the balance, more often than not, disappointing him.”

“Having a body is in itself the greatest threat to the mind... The body encloses the mind in a fortress; before long the mind is besieged on all sides, and in the end the mind has to give itself up.”
