Reason is overrated. Many pundits have argued that a good heart and steadfast moral clarity are superior to triangulations of overeducated policy wonks, like the best and brightest and that dragged us into the quagmire of Vietnam. And wasn't it reason that gave us the means to despoil the planet and threaten our species with weapons of mass destruction? In this way of thinking, it's character and conscience, not cold-hearted calculation, that will save us. Besides, a human being is not a brain on a stick. My fellow psychologists have shown that we're led by our bodies and our emotions and use our puny powers of reason merely to rationalize our gut feelings after the fact
