在臺灣當代名儒當中，陳大齊的學術思想在他本人過世之後較少受到討論。如此 的忽視會造成學界在援引前人學術資源、累積學術研究成果上的缺失。為了濟補缺漏，增益 研究資源，本文擬對陳大齊的學思之路與研究成果加以探討，使臺灣儒學史的研究更為完整 。 整體說來，陳大齊的學思之路，最初研究心理學與理則學，其後漸集中於理則學或名學，於 來臺之後轉往中國名學，最後則歸本於儒學研究。對理則學與名理的興趣貫穿他一生的學術 研究，並延伸到他對古典儒學的研究，使他的儒學研究更具論證性、分析性與嚴謹性，也因 此在當代儒學中具有不容忽視的地位。 誠如美國學者柯雄文（ Antonio Cua ）在其近著《 道德視野與傳統─中國倫理學論集》中所表示，「陳大齊的《孔子學說》是儒家倫理學概念 面向的先驅之作。」 本文為了闡明陳大齊由名學走向儒學，因而使儒學更具論證性、分析性與嚴謹性的學術道路 ，將首先簡述其生平與著作，明其一生與學術的重要轉折，進而為其學術思想發展分期；之 後再分就理則學、因明研究、古典儒學研究等三方面，討論陳大齊在學術思想方面的貢獻； 最後，再試圖提出作者對陳大齊整體學術成果的評價。

　　　　　The thought of Ch'en Ta-ch'i, though less discussed in Taiwan after his death due to the overwhelming influence of contemporary Neo-Confucian figure such as Mou Tzong-san, is significant for its logical and ethical approach to Confucianism, in contrast to Mou's transcendental and ontological approach. In the present paper, I attempt to reconstruct and evaluate the evolution and achievements of Ch'en's Confucian studies. As aptly put by Antonio Cua in his Moral Visions and Tradition--Esasays in Chinese Ethices, "The pioneering study of the conceptual aspects of Confucian ethics has been Ch'en Ta-ch'i's Kung Tzu hsuehshuo." Ch'en began his studies in psychology and logic at the beginning of the century, gradually making logical studies his main focus. On the basis of his training in logic, he first performed research on Indian logic, and then later extended his research to Chinese logic. After coming to Taiwan with the Central Government in 1948, Ch'en began to do research on the logical and conceptual aspects of Confucianism, starting with Hsun Tzu, and then tracing his way back to Confucius and Mencius. Through in-depth study of the basic concepts, ethical argumentation and ethics of virtue in Confucianism, Ch'en gained a profound understanding of Confucian ethics. Indeed, he can be considered a pioneer in these areas of research. After analyzing and evaluating Ch'en's research on logic, I conclude the paper by presenting an overall synthesis of his thought and intellectual achievements.
