Having emotions represents what people value. Just as cognition concerns whether things are true and false; emotion is about whether they are good or bad. Thus, emotion may be a necessity for rationality, rather than its antithesis. Our emotion research shows that emotional feelings provide compelling information about the value of outcomes, actions, and objects. As a result, although it can also lead to excess, emotions provide a coherent basis for judgment and decision. In addition, I suggest that the current psychological theory is helpful in thinking about rationality because it assumes more than one mode of reasoning. Similarly, current emotion theory is helpful because it assumes more than one kind of good.
