內容摘要：羅欽順是明代中期被稱為「朱學後勁」的思想家，他亦自稱其理氣觀是繼承二程與朱熹而來。然而實際上羅欽順是以「氣」作為宇宙中最根本的存在，天地萬物莫非是一氣聚散；「理」則指稱氣運行的條理，因此理疑不可分，理氣本是一物。「理」既是「氣之理」，則代表了宇宙中的秩序性；萬物各各不同的表現中(稱之為「分殊」之「理」)，自有某些共通的，一致的道德性潛能(稱之為「理一」之「理」)，是天人相通，成聖成賢的潛在依據。因此羅欽順的理氣觀雖以「以氣為本」、「理氣一物」奠基，對「理一」之「理」的追求卻讓他仍保有「近朱」的色彩。

　　　　　Abstract: Luo Qin-shuen was known as the "successor of Neo-Confucianism" in the middle of the Ming Dyansty, claiming his ideas of Li and Qi an inheritance from Cheng Yi's, Cheng Hao and Ju Xi. Actually Luo refers to Q as the essential being of the universe. The universe is nothing but the gatherings and breakings of Qi, while Li is the law of the working of Qi. Therefore Qi and Li are one and the same. Li is the law of Chi and supposedly represents the order of the universe. The various expressions of the creations (which is called the law of "differentiation") have some consistent moral potential in common, which would possibly cause trigger the communication between Heaven and Man as well as the achievement of holiness and sageness. Though founded on Qi and the oneness of Li and Qi, Luo's Qin-shuen's interest in Li shows that he is deeply informed by Ju Xi.
