Sociobiologists point to the preeminence of heart over head at such crucial moments when they conjecture about why evolution has given emotion such a central role in the human psyche. Our emotions, they say, guide us in facing predicaments and tasks too important to leave to intellect alone — danger, painful loss, persisting toward a goal despite frustrations, bonding with a mate, building a family. Each emotion offers a distinctive readiness to act; each points us in a direction that has worked well to handle the recurring challenges of human life.
