 A Cerebral Cortex Makes Animals Programmable

As we ascend the scale of cerebral development the possibility of teaching increases. It becomes possible to domesticate and train these higher-brain animals in just the measure that their brains are developed. You can teach very little to a fish or a reptile, but directly you come to the higher cerebral mammals you are confronted by the new possibility of establishing an artificial, taught, motive system to control, supplement or altogether replace natural instinct. You must catch them young...

 One Who Can See in the Country of the Blind

"Why did you not come when I called you?" said the blind man. "Must you be led like a child? Cannot you hear the path as you walk?" Nunez laughed. "I can see it," he said.

"You'll learn," the blind man answered. "There is much to learn in the world." "Has no one told you, 'In the Country of the Blind the On...
