        中庸本来是孔子所倡导的最高的一种修养标准，是指处理应对任何事，都能够恰如其分、恰到好处。孔子以后，中庸逐渐成为儒家的一种方法论，即不论思维还是处事，都要尽可能符合事情的原貌，不走极端，不搞绝对。中庸之道的积极影响在于一是不走极端，不搞绝对的思维方法使得中国文化拥有极大的包容性，一切外来的异质文化，都能在中国生根，发芽，生长。二是中庸之道使人们懂得并且相信，事情的本来面目多数情况下不在极端的状态中，这种心态强化了人们思维的全面性，和人们对于正确东西的追求和接受。中庸之道也有其消极的影响，那就是一方面它使得人们的是非观不够明确；另一方面，经常对于明确的是非观的消解，也自然地妨碍了个性的明朗和发展。
