笔者读过这样一个故事:古希腊哲学家第欧根尼喜欢蹲在一只木桶里晒太阳,一边天马行空地思考池的哲学。国王亚历山大屈尊礼贤,走近问他:“我能帮您做点什么吗?”“不识抬举”的哲学家竟睨而答曰:“我需要的只是请你走开点,不要挡住我的阳光。” I read such a story: the ancient Greek philosopher Diogeni like to squat in a bucket in the sun, while abstract thinking about pool philosophy. King Alexander condescended, approached and asked him: “Can I help you to do something?” The philosopher who did not know how to lift it said: “All I need is for you to go away and not to block me The sunshine. ”
