Liang Shuming's lifelong focus was on the future of China and the future and destiny of human beings as a whole.With a distinct social ethical concern,his cultural theory is based on the premise of theory of human body-heart,with civilization theory,human life theory and morality theory as its ultimate destination.The ethics he is concerned about is not the"small ethics"at the level of moral principles or behavioral norms,but the"big ethics"at the level of human heart and human nature,which he understands as"reason"or"reasonableness".To enhance mutual understanding among different countries and civilizations,promote peaceful coexistence of human beings,and ultimately achieve the ideal of"all people are of one family in Tianxia"and"of one civilization in Tianxia",the key is to make human beings have"clear mindedness and insight"from the perspective of world civilization,recognize the fundamental significance of universalized ethics to culture.Liang Shuming's cultural theory undoubtedly implies important insights for promoting the"second combination",building modern civilization of the Chinese nation,as well as constructing a community with a shared future for mankind.
