This chapter follows the research of A. C. Graham (1919Graham ( -1991 and ShěnYǒudǐng 沈有鼎 (1908-1993) on the textual history of the Gōngsūn Lóngzǐ 公孫龍子 (hereafter GSLZ). After a few introductory remarks in the first section, the second section illustrates the secondary nature of the GSLZ by giving a concise overview of the various ways its compilers drew on the "dialectical chapters" of the Mòzǐ (Mohist 'Canons'). In the third section, I gather evidence for the medieval renaissance of Mohist dialectics, which was closely associated with the figure of Gōngsūn Lóng from its beginning, in order to suggest that it was in the light of this renewed interest in language and argument that the extant GSLZ was composed. If the GSLZ is indeed as late as this, its compilation would coincide with a period during which Buddhist scholastics enjoyed increasing influence in China. Thus the main part of the chapter is dedicated to disclosing traces of a Buddhist impact on the argument, structure, and compilation of the GSLZ,o r some of its parts. Even if the GSLZ lacks manifest traces of Buddhist influence, such as quotations of Buddhist works or explicitly Buddhist terminology, there is evidence to suggest that a strong Buddhist background informed the compiler(s) of the work. In section four, I show that the argument in the 'Discourse on Hard and White' (Jiānbái lùn 堅白論, hereafter JBL) closely resembles a line of reasoning in a Buddhist work translated in the early fifth century CE. In section five, I demonstrate how certain Buddhist discourses about the nature of causation, time, and language provide the very rationale that structures the 'Discourse on Penetrating Change' (Tōngbiàn lùn 通變論, hereafter TBL) and the 'Discourse on Names and Substances' (Míngshí lùn 名 實論, hereafter MSL). The sixth section explores the composition of JBL and its pivotal role in the compilation of the entire GSLZ from the perspective of three of its crucial terms and their probable Buddhist implications. Section seven returns to Graham'sa n dS h ěn's arguments for dating the composition of the received GSLZ as late as in the second half of the seventh century CE. On the basis of various Buddhist references, this section attempts to gain additional insights into the possible history of compilation of the GSLZ. The peculiar nature of the parallels in Buddhist texts, along with internal evidence in JBL and TBL, suggest that the GSLZand especially these two chapterspossibly assumed their present shape through two different stages of editorial activity, in the fifth and the late seventh centuries CE, respectively.
