In Descartes’ Error: Emotion, Reason, and the Human Brain,2 neuroscientist Antonio Damasio explained a groundbreaking discovery he made. Studying people who had damage in the part of the brain where emotions are generated, he found that they all had something peculiar in common: They couldn’t make decisions. They could describe what they should do in logical terms, but they found it impossible to make even the simplest choice. In other words, while we may use logic to reason ourselves toward a decision, the actual decision making is governed by emotion.
