We have two brains, two minds--and two different kinds of intelligence: rational and emotional. How we do in life is determined by both--it is not just IQ, but emotional intelligence that matters. Indeed, intellect cannot work at its best without emotional intelligence. Ordinarily the complementarity of limbic system and neocortex, amygdala and prefrontal lobes, means each is a full partner in mental life. When these partners interact well, emotional intelligence rises--as does intellectual ability.
