In order to establish his "school of principle" system of thought, which was founded on objective idealism, Zhu Xi proposed a theory of "investigating things and exhausting principles" [gewu qiongli]. This became the epistemological foundation for his system of thought. This epistemology formed an organic whole with his world view. On the one hand, his "theory-of-investigating-things" epistemology opened up pathways for his system of objective idealism; on the other hand, his "school-of-principle" system formed the theoretical foundation for his epistemology of (...) "investigating things" and gave this epistemology its obviously metaphysical characteristics. (shrink)
