本文聚焦於李光地、李清馥祖孫二人，以及其所承繼的閩地學術傳統，並透過各種史料文獻，詳細討論此一學術傳統如何由「吾學」向「閩學」轉化的思想史歷程。本研究並嘗試由地方社會史的角度，重新詮釋解讀李氏在閩地鄉里中的理學實踐，如何配合著其延續一地學術願景。經由多方面取徑來討論理學在福建地區的發展，以及其在地化的相關演變過程。筆者透過對史料文獻的討論與詳細分析，進而發現明末清初時期閩地理學傳承的形成過程中，若干師友脈絡被特別加強，但有一些師承關係卻被刻意淡化。事實上，李光地與其孫李清馥可以說在其中扮演了極為重要的角色，李光地兩代人的重要性正在於他們試圖將明中葉以來蔡清、陳琛、林希元等人的思想編纂成一地的學術淵源。我們由李氏後人李清馥編纂的《閩中理學淵源考》中，可以觀察到李氏祖孫兩代人對於閩地理學傳承的理解與編排過程，從而深入探討明清之際閩地理學的發展與變遷。最後，筆者進一步由李光地對於理學思想的轉化與實踐著手，詳論其在閩地理學思想演進中的重要地位，並且綜合討論其對閩地學術傳承的曲折延續，以及轉化的歷史進程。
