The Competing Subsystems of the Brain

The brain is made up of competing subsystems, says David Frum. The rational system cares about analysis of things in the outside world, while the emotional system monitors your internal state and worries whether things will be good or bad. If you were an emotionless robot who rolled into a room, you might be able to analyze the stuff around you, but you would be frozen with indecision on what to do next.
