     Americans wear black for mourning while Chinese wear white. Westerners think of dragons as monsters

while Chinese honor them as symbols of God. Chinese civilization has often shown such polarities (极性)

with the West, as though each stands at extreme ends of a global string. Now in the University of California,

Berkeley, a psychologist has discovered deeper polarities between Chinese and American cultures-polarities

that go to the heart of how we reason and discover truth.

     His findings go far toward explaining why American cultures seem to be contentious and Chinese cultures

so passive, when compared to each other. More importantly, the research opens the way for the peoples of

the East and the West to learn from each other in fundamental ways. The Chinese could leam much from

Western methods for determining scientific truth, said Kaiping Peng, a former Beijing scholar, who is now

a UC Berkeley assistant professor of psychology. And Americans could profit enormously from the Chinese

tolerance for accepting contradictions in social and personal life, he said.

     "Americans have a terrible need to find out who is right in an argument," said Peng. "The problem is that

at the interpersonal level you really don't need to find the truth, or maybe there isn't any." Chinese people, said

Peng, are far more content to think that both sides have flaws and virtues, because they have a holistic (整体

的) awareness that life is full of contradictions. They do far less blaming of the individual than Americans do,

he added.

     In studies of interpersonal argument, for example, when subjects were asked to deal with contradictory

information stemming from conflict between a mother and a daughter or a student and a school, Peng found

that Americans were "non-compromising, blaming one side-usually the mother-for the causes of the problems,

demanding changes from one side to attain a solution and offering no compromise" in dealing with the conflict.

Compared to this angry, blaming American stance, the Chinese were paragons (模范) of compromise, finding

fault on both sides and looking for solutions that moved both sides to the middle.
