The horizons for the modern study on Zhu Xi are pluralistic; while the Marxist and historical approaches are based on historical criticism, Chien Mu and Yu Ying-shih's historical approach is meant to explicate its historical rationality and solve contemporary cultural conflicts. Mo Zong-san approaches Zhu Xi through Kant's philosophy and the philosophy of mind to facilitate the further development of Confucianism, while Lo Kuang's scholastic approach, meaning to introduce Catholic philosophy into Chinese culture, is also an important dimension in the modern study of Zhu Xi. Alternating between the systematic and the historic methodologies, Lo Kuang strongly approved Zhu Xi's doctrine because his philosophical system of benevolence, theory of mind-nature and theory of moral cultivation are supplementary to scholastic philosophy. Based on scholasticism, Lo Kuang redressed the problems with Zhu's philosophy: the conflicts caused by the dichotomy of Ii and qi, the insufficiency of essence as the criterion of good and evil and the inability to solve the problem with the cause of the individual being. Exploring deeply Lo's study of Zhu Xi and the possible approaches to assimilate Chinese and western philosophies, we could see how to understand Chinese philosophical frameworks creatively and promote the autonomy of contemporary Chinese philosophy.
