《集古今佛道论衡》是唐初释道宣编纂的一部佛道交涉著作。该书经道宣两次编纂后,又掺入了后人杜撰的一些内容。唐高宗朝的宫廷佛道论衡是该书编纂的直接诱因。因为对待掺入文献的态度不同,《集古今佛道论衡》在流传过程中形成了3个版本系统。该书在中古文献学、宗教学以及文化学研究中有着重要的参考价值,非常值得关注。 “Collection of ancient and modern Buddhist theory of balance” is the beginning of Tang Road declared compilation of a Dharma negotiations. After the book was declared twice codified, it incorporates some content invented by descendants. Tang Gaozong court palace Buddhism Lun Heng is a direct incentive for the compilation of the book. Because of the different attitudes toward the incorporation of the literature, “set ancient and modern Buddhist theory Lun Heng” in the process of formation of the three versions of the system. The book in the Middle Ages literature, religious studies and cultural studies has an important reference value, is very noteworthy.
