This paper probes the structure of moral feeling and reason described by Mencius＇s from five perspectives： （1） In view of the relationship between feeling and reason, is it better to use the expression ＂siduan＂ or the expression ＂sixin （Four Heart-minds）＂？ （2） In view of dispositional feeling, what are the four original sources？ （3） In view of moral feeling, what are the structural order of the four sources and the corresponding procedure of reasoning of four heart-minds of Humanity？ （4） In view of positive feeling, how does moral feeling grow out of the goodness of human nature？ （5） What is the global value of Mencius＇s ideas on human moral feeling？ The author concludes that Mencius＇s thought on moral feeing has a global value and cross-cultural significance, and that Chinese wisdom is more than regional but universally applicable. The structure of moral feeling and reason that Mencius identified is in accordance with the principles ofzhiliang （grasping the two poles of the beginning and the end） and yongzhong （emloying the middle）. The principles ofzhiliang and yongzhong are true universal wisdoms of Confucianism, which should be rekindled today. From a practical point of view, ＂the Way begins from moral feelings,＂ and Confucius and Yah Hui＇s seeking the simple, virtuous life is an ideal model of emotional well-being.展开更多

I argue that this concept is essentially a trope of reflection and that reflection is thought of itself as itself which involves a ＂turning around upon oneself.＂ But we do not see ourselves as we actually are, or in our entirety as a physical entity; self knowledge is limited by our nature. What we do not see or attend to is glossed over with the idealizations that are attached to our interest and these are informed by instinctual, or unconscious, intent. The relation between self and other is both contained by and expressed in interpersonal and societal interaction, but still there is an inner aspect that remains sovereign and intimate. Societal values inform our identity, but cannot touch the inner self （or intimate self）. We only ever experience ourselves no matter how similar or intimate we are to others. Although physically different from others we mostly aim to be known （identified） in accordance with our own sense of value and self estimation, yet we do not escape judgment from others. One may resist any evidence or opinions about themselves from others that are not in accord with this sense of self value whilst easily accepting ideas and values to be true or accurate facts about them that they only wish to be true. From these two sources of ideas of oneself, internal and externally derived, we form a sense of ourself in comparison to ideal others. This sense of identity informs our actions and choices. We may continually monitor the effect our self-belief has on others and adjust our self-attitude accordingly. Or we may fail to see that others do not share those beliefs we have about ourselves （e.g., a job interview）. Narcissism is a human tendency to either exaggerate or underrate one＇s power or beauty and this leads to false self beliefs. These ideas about oneself are ego-syntonic, within the boundary of the ego, and are thus not （immediately） experienced as being false. Thus, the question as to what is real and what is imagined is at stake in considering how we reflect upon a self which is essentially also a reflection of how others see them. The concept of Narcissism involves this inviolable choice to act for ourself or for others＇ sake in the pursuit of freedom and satisfaction in social interactions. Taken as an axiologicaUy neutral mode of analysis, Narcissism illuminates the problem of being self in the world of others and goes to the possibility of self determination and knowledge. Specifically, I aim to show that self reflection is the key element of the idea or thought of self, but that form of reflection alone is not enough to ensure error since it is based on a fundamental illusion of ego integrity. However, the attentive mindfulness or open ideation of a purer form of thought which I term ＂active reflection＂ allows the possibility of new perspectives hitherto unavailable to the self to form, ensuring that rectification can proceed from experience展开更多
