众所周知,道德是人类在长期的社会生活中所形成的行为原则和规范的总和,随着社会的发展变化而反映着人类的文明与进步。恩格斯说:人们自觉地或不自觉地,归根结底总是从他们的阶级地位所依据的实际关系中——从他们进行生产和交换的经济关系中,吸取自己的道德观念。这个理论就整个人类社会的道德而言,具有普遍的指导意义。 It is well known that morality is the sum of the principles and norms of behavior formed by human beings in long-term social life and reflects the civilization and progress of mankind as society develops and changes. Engels said: People consciously or unconsciously, in the final analysis, always derive their own moral values ​​from the actual relations under which their class status is based-from the economic relations in which they are producing and exchanging. This theory has universal guiding significance for the morality of the entire human society.
