作为清初普通儒家基督徒,刘凝为世人所熟知的身份是经学家、音韵学家。本文尝试通过爬梳相关文献资料对其家族、生平、著作、交往等进行详细考证。根据考证,刘凝出生于1620年,于1710年左右去世,在1687年赴任崇义训导之前即已受洗入教。刘凝不仅对文字学、音韵学有较深的造诣,而且通过他的人际网络将西学西教进一步传播出去,从而在某种程度上对清初学术界产生积极影响。 As a common Confucian Christian in the early Qing Dynasty, Liu Ning’s well-known identities are scholars and phonologists. This article attempts to carry out a detailed textual research on its family, life, works, contacts and other related documents through the book. According to textual research, Liu Ning was born in 1620 and died in about 1710, before being enrolled as a disciple of Chongyi in 1687. Liu Ning not only has deep knowledge of philology and phonology, but also spreads the western education through western communication to some extent, which has a positive impact on academia in the early Qing Dynasty.
