Abstract
I intend to trace the original meaning of "unifying two into one" as it is treated in the Tung-hsi chün. The phrase "unifying two into one" appears in the chapter entitled "The Three Verifications" [San cheng] of Fang I-chih's most representative work, the Tung-hsi chün. I am not very familiar with this book, and feel that there are still many places which I do not understand even though I have read it several times. Nonetheless, the philosophical system of the Tung-hsi chün is relatively clear, and if we try to place the notion "unifying two into one" in the whole context of this book, we then can decipher its original meaning and some of its real ideas. I now present my personal opinion about this book to our comrades for their reference
