The Article divides socialist essence into historical one and essence of value based on ontology,and correspondingly divides the evaluation of socialism into historical one and value one based on epistemology.Meanwhile,it shows the logically isomorphic relation between the dual essence of socialism and the evaluation,and restores the relation into efficiency and fairness one.

理论界在探讨邓小平关于社会主义本质论时存在两大缺失：一是未能从本体论上区分社会主义历史本质与价值本质的关系；二是没有把社会主义二重本质与认识论上的二重评价即历史评价与价值评价结合起来，并把它们的关系还原于效率与公平的关系。

It is also a form of dualism, because it allows the irreducibility of mental states and properties.
