司马光的易学和史学互动承先秦到隋唐“易史互动”的传统而来，又受到北宋尊儒卫道和挽救时弊现实需要的影响。司马光以史证《易》思路集中在阐发阴阳相承的社会理想存在形态上；在易学影响下，司马光为人类社会发展寻到了一个根本性的规律——“易”道，还形成了辩证的历史变易观。司马光的易学思想和史学思想都以资治为导向和目标，三者相互联系、相互贯通，实现了“内圣”与“外王”的统一。

The Interaction between Sima Guang's Yi-ology and Historiography inherits the tradition of "interaction between Yi-ology and historiography" from pre Qin to Sui and Tang dynasties, and is also influenced by the practical needs of respecting Confucianism, defending orthodoxy, and treating social ills in the Northern Song Dynasty. Sima Guang's use of historical evidence to prove the ideas of Yi-ology focus on elucidating the social ideal existence form in which Yin and Yang are connected; Under the influence of Yi-ology, Sima Guang found a fundamental law for the development of human society - the "Yi" Dao, and also formed a dialectical view of historical changes. Sima Guang's Yi-ology and historical thoughts are both guided and aimed at political thoughts and practice, and the three are interconnected, achieving the unity of "internal saints" and "external kings".
