《易》是我国古代第一部系统的哲学思想典籍,涵盖了先民对宇宙现象和事物变化规律的认知与描述。在《易》当中存在着理性观念的早期萌芽,但这种理性化观念并没有在后来的文化史上持续传承。而《易》本身流传和解读也存在偏差,造成了《易》学的边缘化和神秘化,以至于其文本最终被排除在中原文化主流核心圈之外。这种现象的发生,与农耕文明体系自身特性有着密切联系。 “Yi” is the first systematic philosophical thought book in ancient China, which covers the cognition and description of the ancestors’ laws of the universe and the changes of things. There was an early sprout of the rational concept in the Book of Changes, but this concept of rationalization did not continue to be inherited in later cultural history. However, there are also some deviations in the dissemination and interpretation of “Yi” itself, resulting in the marginalization and mystification of Yi Studies so that its texts are eventually excluded from the core circle of the Central Plains culture. The occurrence of this phenomenon is closely linked with the peculiarities of the farming civilization system.
