穷理尽性

彻底探究人和事物发展变化的原理，洞察人和事物的本性。中国古人认为，认识世界和认识自我，改造世界和提升自我，是同步互动、有机统一的过程。通过这一过程的努力，才能达到人与自然和谐平衡、主体与客体融合为一的理想境界。

Explore the Nature of All Things

This term means to thoroughly explore the fundamental nature and pervasive laws of humanity and all things, which includes the exploration of natural phenomena, cosmic laws, and local events. We must fully understand how all things are connected, so that we can contribute to all things flourishing in their roles. Ancient Chinese believed that to understand the world and oneself, and to reform the world and improve oneself are a process of interaction and unity. Only when such process advances can the harmony between humanity and all things be accomplished.

引例穷理尽性，以至于命。（《周易·说卦》）（探究与人和事物有关的一切原理和规律，洞察人和事物的天性，从而达到与天命合一、安身立命的理想境界。）

Thoroughly explore the nature of humanity and all things and maximize their natural roles, then the ideal realm of people acting in line with laws and living in peace with nature can be reached.（The Book of Changes）
