摘要： 在“孔孟之道”所象征的儒家文化传统中，“孔仁孟义”中的“义”和“思孟学派”中的“心性”都与孟子的思想人格紧密关联。“义”具有“天下道义”的奥义，它对于“家”中的“亲长”权力和“国”中的“君父”权力均有神圣的超越性，常以“大义灭亲”和“替天行道”标而出之；“心性”则是对《中庸》“性命”观念的创造性转化，突出了儒家的认识论和宇宙论的主体性与伦理性。在孟子思想体系中，“心性”与“道义”的结合，揭示出了人的普遍道德权利和伦理义务，也蕴含着其对天子、国君和权臣的世俗权力的伦理性超越和限制，其辩证的结论就是：当世俗权力侵害普遍道德权利时，社会变革就成为维护人的普遍道德权利的必然而正当的选择。

Abstract: In the Confucian tradition symbolized by The Tao of Confucius and Mencius, the doctrine of Mencius' Righteousness in the Paragon of Confucian Humaneness （kong ren） and Mencius' Righteousness （meng yi） has beenassociated with Heart-Nature（xin xing），which leads consequently to an intended personality of Confucian ethicsand politics. The concept of righteousness, for Mencius, connotes the cosmological ethics under the heaven,transcending the secular powers of father in family and monarch in country under the auspices of heavenly sanctity. Such transcendence is often vindicated by Righteousness-Oriented Destruction of One's Relatives（da yi mieqin） and The Overthrow of Government by Performing Heaven’s Mandate（ti tian xing dao）．The concept of Heart-Nature in Mencius was the transformation of Heaven-Mandated-Nature （xing ming） from the Doctrine of theMean （zhong yong），attesting to the subjectivity and ethics in Confucian epistemology and cosmology. The combination between Heart-Nature and Tao-Righteousness in Mencius reveals the universally existed moral rights andethical obligations of human beings as well as the ethical transcendence and restrictions on secular powers of Sonof Heaven, monarchs and dukes. The dialectics exposed in this relation between moral rights and its restrictionson administrative powers justifies social changes in cases of moral rights being violated and abused by administra-tive powers.
