朱一新(鼎甫)之學，論述甚廣。<<無邪堂答問>>所載，舉凡政治、經濟、軍 事、文化、教育諸事，皆所涵蓋。其中最值一提，當為乾嘉學風的評駁。先生以宋 學精神和之以漢學的精謹，於乾嘉諸儒有所論斷。尤以戴(震)、阮(元)之作，迭 有評議。以為二氏之述，直就論經的考據以言，持論與義理的微言頗有懸殊；如純 就考據，則雖立漢學之名，終不免泥沼之譏。後之究思想史者，雖歸先生於漢、宋 和同，然自書中微意相觀，則先生必為立宋而摒漢；亦可謂正宋學而斥漢學，此與 陳澧以漢、宋相合之說，大抵未同。因之，本章之論，所謂「漢學者之弊」、「重訓 詁的經說」也者，所採諸見，皆源先生之用思，亦見先生微義之所在；而如沿波以 循，尋繹所致，不出程、朱之涂，則振葉探根，蓋亦知先生學之所本。是晚清之際， 公羊諸說紛起，先生獨能別樹一幟，於清之儒者，可謂非等閒之人。本文綜述先生 之作，或未全然環窺全豹，但能得其一體，亦允知先生言談謦欬，指尺之間，道亦 在其中矣!
