From a sociological perspective,understanding moral internalization becomes more comprehensive and clearer,allowing for a deeper comprehension of its profound implications for individuals and its significant importance for social development and progress.On the one hand,society grants individuals identities,compelling them to undergo moral internalization for group identification.On the other hand,individuals need moral internalization to ultimately gain a sense of belonging within the social system.Moral internalization can deepen individuals'moral identification,stimulating moral behavior;integrate moral knowledge,emotions,intentions,and actions,enhancing individual moral cultivation;assist individuals in self-reflection,promoting self-regulation;establish social bonds,strengthening individual social connections;maintain social operational order,shaping the moral atmosphere of society;and foster a positive moral ethos,promoting the positive development of society.For the formation of common values across society,moral internalization is necessary.It helps people define their own moral cognition that conforms to social norms based on common behavioral guidelines,thus nurturing their moral emotions,honing their moral will,and ultimately transforming into moral behavior,achieving a qualitative leap in moral internalization.
