Neither human nature nor personality can be independent of culture. Human beings share certain social norms or rules within their cultural groups. Over 2000 years ago, Aristotle held that man is by nature a social animal. Similarly, Xun Kuang (298-238 B. C. ), a Chinese philosopher, pointed out that humans in social groups can not function without shared guidance or rules. This book is designed to provide readers with a perspective on how people are different from, and similar to, each other --both within and across cultures. One of its goals is to offer a practical guide for people preparing to interact with those whose cultural background is different from their own.
