Many studies and sciences have been highly developed in the 20th century. They promoted the quality of human life, and changed the human life style fundamentally. Individual freedom and right in Political system, material abundance in capitalist economic system, liberation from the physical labor, treatment of disease, life prolongation, accumulation and exchange of information might be evaluated like as positive sides, as if ideal utopia should be realized. But there are lots of negative effect behind these growth and development at the same time. We experienced twice World war, and yet face with lots of local dispute and civil war, hunger and disease, economic and social inequality, egoism and moral frigidity, dismantlement of family, infringement of human right, global environmental pollution etc. In these crises situation, the 21st century universal ethics is presented in order to promote mankind happiness and prosperity. But there are some critics that new universal ethics has limits of being individual, abstract, and western-centric.
My paper aims are as follows : to emphasize that Hyoje as the core of family ethics in oriental confucian culture can be a base that makes up for the weak points of the new universal ethics, ; the social expansion of Hyoje can be helpful to overcome the various ethical crises situations lately, ; and ultimately it can improve mankind happiness and prosperity. To put it concretely, 1) to survey the arguments about the 21st new universal ethics for mankind happiness and prosperity, 2) by the expansion oriental confucian cultural Hyoje ethics from family to society-state-world-things, it can be a consistently penetrated base of universal ethics, 3) in order to reestablish Hyoje ethics more adamantly, we need seriously reflect and accept the critics, 4) and we must harmonize Hyoje ethics with modern demands, and re-explain the essential meaning of Hyoje.
