Interesting thought

He often argued that human intelligence was more trouble than it was worth. It was more destructive than creative, more confusing than revealing, more discouraging than satisfying, more spiteful than charitable.

There were times when he saw man, with his giant brain, as equivalent to the dinosaurs. Every schoolboy knew that dinosaurs had outgrown themselves, had become too large and ponderous to be viable. No one ever thought to consider whether the human brain, the most complex structure in the known universe, making fantastic demands on the human body in terms of nourishment and blood, was not analogous. Perhaps the human brain had become a kind of dinosaur for man and perhaps, in the end, would prove his downfall.

Already, the brain consumed one quarter of the body’s blood supply. A fourth of all blood pumped from the heart went to the brain, an organ accounting for only a small percentage of body mass. If brains grew larger, and better, then perhaps they would consume more – perhaps so much that, like an infection, they would overrun their hosts and kill the bodies that transported them.
