With some primary understanding on the ideas of human rights that are developed by people of three generations and on the related concerns of contemporary Hong Kong and Taiwanese Confucians, the writer tries to explore and reflect on Tang Jun Yi's enlightenment and understanding about the modem ideas of liberty and human rights through three different perspectives: humanistic ideas about human rights, the doctrine of liberty that explicates cultural values, and the reason-oriented philosophy of human rights. Tang Jun Yi upheld the idealists' universal reason as the theoretical foundation of liberalism and commended the Confucian liberal spirits of liberty, equality, humanistic tolerance and democratic immanence.
