孟子的义利观是孔子“义以为质”功利观在战国时期的继承和阐扬。盂子以心性之说奠定仁义的形而上基础,从谴责霸道、宣扬王道入手,树起了仁政理想的旗帜。孟子对天下逐于利的现实持有激烈的批判态度,对在利益面前人性的沦丧表示义愤,但是,他并没有把义与利断为两截,民本主义的立场使他没有由此走向极端。与其说他是从社会批判转向道德形而上建构的,不如说他是从道德形而上中找到批判现实的利器。 Mencius’s view of righteousness and benefit is the succession and expounding of Confucius’s view of utility of righteousness in the Warring States period. Gou Zi to lay the heart and soul of the metaphysical foundation of benevolence, from condemning hegemony, promote the king to start, set up a banner of benevolent ideal. Mencius held a fiercely critical attitude to the reality of world-by-vanity and expressed his indignation at the loss of humanity before the interests were gained. However, he did not take both righteousness and judgment as the two ends, and his position of the people led him not to go from here extreme. Instead of turning from social critique to moral metaphysical construction, he is better to say that he is from the metaphysics to find the real weapon of criticism.
