近百年来 ,学界对《墨经》“类”概念的理解颇多分歧。总结前辈学者对“类”的研究 ,我们认为 ,“类”可以用“本质属性”来解释 ,但不能用“种属关系”来强解 ;在用“本质属性”解释“类”的同时 ,不能降低甚至排除用“相似性”对“类”的解释 ,因为这两方面的解释在理解《墨经》的逻辑类型时都不可或缺。 Over the past century, there have been many differences in the understanding of the concept of “class” by “Mojing” in the academic circle. To summarize the research of “class” by predecessors and scholars, we think that “class” can be explained by “essential attribute”, but can not be solved by “genus relationship”; while “class” is explained by “essential attribute” The explanation of “classes” by “similarity” can not be reduced or even ruled out, since both interpretations are indispensable in understanding the logical typology of Mohist.
