The so-called Critical Buddhism was originated by two Buddhist scholars at Komazawa University: Hakamaya Noriaki and Matsumoto Shiro. It stirred up great controversy by its claims that the teachings of Tathagatagarbha, Buddha-nature, original enlightenment, and the philosophy of Kyoto School are not Buddhist, and aroused great interest and responses from Buddhists and Buddhologist in Japan.( Shih, Heng-Ching¡F2001) They condemn the ideas of Buddha Nature, Tathāgatagarbha and Original Enlightenment developed in China and Japan as deviating from the fundamental Buddhist thoughts of pratītyasamutpāda and śūnyatā, thereby backtracking to the substantialism of the idea of Brahman in the Upaniṣads.At the level of social criticism, Critical Buddhism blamed the idea of Wa (harmony), which derives from Tathaagatagarbha thought, for social discrimination and injustice.(Yu-Kwan Ng¡F2009) The same controversy caused by Zhi Na Nei Xue Yuan and New Confucianism also occurred in China. Therefore,the development of Buddhism in China and Japan both became the representations of East Asia. The development of Buddhism became not only the characteristic of civilization, but aslo the public philosophy of East Asia through the concept of ¡§Nothing¡§(µL).
