南宋‧朱熹立足在孟學發展史上承先啟後的重要關鍵，以「道統」為尊的治經詮釋立場，重張儒學大旗回應當代佛、老思想挑戰，以儒者治經自許，黽勉為志集註《四書》，治經方式繼隋唐「漢學」舊風又下開「宋學」新風，以理學註經的進路重振儒學，表彰《大學》、《中庸》、推尊《論語》、《孟子》，提高《孟子》經典由子部升格至「經部」，其《四書集註》大成之功，以「集註」體例疏通儒家哲學體系，更奠定了《孟子》經典意義在經學歷史上的正統地位。朱熹治經，以返歸儒家道統為職志，由孔、孟「聖賢之意」，立「自得之意」，借鑑經典的意義視域，註經、解經，與經典文本視域融合。其集註《四書》，透過儒學語境，以註釋的方式，直探孔、孟道統，從註經解釋為宋代理學發聲，成功地直探孔孟道統的系譜傳承。本文立基在孟子學的詮釋脈絡，揭櫫朱熹建立在永恆普遍的天道性命信念上，融冶漢學／宋學，以「理學」註孟，此一通經明理所展開的新孟學，別具匠心，為孟學史開創出形上意涵，深具特殊意義。因此，本文擬以三節試析朱熹「性即理」、「心統性情」、「格物窮理」三面向析論朱熹《孟子》學說的詮解與要旨，與其所展開的形上思辨皆為本文研究之所要。
