刘歆的《周礼》学及其在两汉之际的传承谱系

两汉之际是《周礼》学的奠基和发轫时期。刘歆是《周礼》学的奠基人和开拓者。约略说来刘歆对《周礼》学发展所做的贡献，主要有如下三端：首先，刘歆在与其父刘向受诏校理秘府图书时，不仅将《周官》（《周礼》）这部几乎不为世人所知的典籍著录于《七略》之中，而且还“独识”《周礼》的价值，顶住各方面的压力，不遗余力地向学术界推介这部在秘府之中新发现的典籍。其次，《周礼》一书于王莽当政时被立于学官、设博士主要应归功于刘歆的推动。复次，刘歆不仅研治《周礼》，撰著《周官传》四篇，而且还广收门徒，传授《周礼》之学。两汉之际著名经学家杜子春、郑兴、贾徽、郑众、贾逵及卫宏等人都曾直接或间接地师从刘歆学习过《周礼》。他们或是刘歆的弟子，或是刘歆的再传弟子，都出于刘歆的《周礼》学传承谱系。他们在《周礼》研究领域都做出了重要贡献，从而使《周礼》学逐步发扬光大。
