i think that rationality gets extolled, especially in the tech community, as the optimal way to live, but too often its confused with stoicism. although i have no evidence from cognitive science to affirm/deny her proposition that "feelings can be deeper than thought," it is true that people are disposed to moods on a sub-conscious level. although it is also true that we can consciously work to "change" our moods, to me this is too quickly dismissing their importance in the context of our experiences. yes, moods can set the stage for irrationally poor decisions, but my point is that they're important (not that they should govern our lives). by confronting and engaging with the emotional as well as the rational aspects of a situation, we come to a more complete understanding and can take more deliberate action.
