对于墨家科学理性,往往是从其在物理等方面的科学成果去认识,而把墨家的中绝归结于小生产者的思想并不能顺应历史潮流,从而无法和儒道并称显学。本文认为,墨家的兼爱观中体现的绝对科学理性精神所导致的思想体系上的缺陷才是导致墨家中绝的根本原因。 For the reason of Mohist Science, it is often understood from its scientific achievements in physics and other aspects, and the idea that the Mohist School is attributed to the small producers can not conform to the historical trend, so it can not be said to be conspicuous with Confucianism and Taoism. This article argues that the defects of the ideological system caused by the absolute scientific rationality embodied in the Mohist View of Equality in Love are the fundamental reasons leading to the decline of Mohist School.
