人的差异是客观存在的,既有先天禀赋的原因又有后天机缘的原因。人既有个体属性,也有社会性属性。人的差异更多地表现为状态差异,包括生理差异、职业差异、能力差异、学识差异等。而群的差异更多的是身份差异。在几千年的社会发展中,群的差异存在着不断固化又不断打破的因果循环。群的差异可以缩小,但难以消除。 The difference between people is an objective reality, both the reasons for innate endowment and acquired opportunities. People have both individual and social attributes. Human differences are more manifested as differences in status, including physical differences, occupational differences, ability differences, differences in learning. The difference between groups is more about identity differences. In the thousands of years of social development, the difference between the groups there has been constantly curing and breaking causal cycle. The difference between the groups can be reduced, but difficult to eliminate.
