Rational and Moral Idealism —On the Spirit of Zhu Zi's Theory

：The first principle in Zhu Zi's theory is to establish the noumenal status of Li,which is regarded as the basis of real world and source of value.Zhu Zi set up the transcendental Li.His purpose is to build up a self-evident axiom for moral humanism.So ontology must be carried out through subject(distinction between Mind and Xing),which involves some problems such as Mind governing Xing and Qing,Weifa and Yifa,Heavenly li and nature of Qi,perceptual Mind and moral Mind.Theory of seeking knowledge and self-cultivation is the concrete approach to reach Zhu Zi's moral idealism.
