汉藏语系关注传承和习惯，而非语法，因此其人善于应变又崇尚传统，却不喜欢钻研本质和原理，于是其社会更多的是渐进式演进；印欧语系强调规则和语法，喜欢探讨本质和原理，因此其人讲原则却不重传统，于是其社会经常是颠覆性地变化。总之，人类都充满矛盾。
The Sino-Tibetan languages are concerned with inheritance and habits than grammar, then the people are adaptable and respectful of tradition, care less about the essence and principles, so its society often evolves gradually; While the Indo-European languages emphasize rules and grammar, and likes to explore the essence and principles, then the people focuse on principles not on traditions, so its society often undergoes subversive changes. In short, human beings are full of contradictions.
