《周禮》自問世以來即爭議不斷，論者或視為周初經世大典，或說是王莽、劉歆竄亂聖經所造之偽書，評價毀譽參半。因《周禮》內容涉及古代典章制度的問題甚多，遂成為歷來今、古文家爭論之焦點。過去，由於傳世文獻殘闕不足，坊間幾部常見的經學史論著，當述及漢儒臨孝存和鄭玄首次往復論難《周禮》的這段史實時，多半輕描淡寫，未得深入考究。本文試從清儒纂輯鄭玄《答臨孝存周禮難》所得殘存佚文入手，分析鄭玄與時人辯難《周禮》之言論，歸納出臨氏對《周禮》經文於職官身份、名義稱謂、禮文詮釋、授田分配等內容的疑惑，並探討雙方進行經義疏解各自的問答意識，及運用的考證方法與侷限。藉此瞭解該次問答在《周禮》學史上占有的先驅意義，還臨氏於學術史上一應有之地位。
