More dared to fight against the feudalism ruler and he was a humanist. But he had his own limitations. More is not a revolutionary, nor does he intend to provoke revolutionary actions by the people or the ruled class. The slave system that solves the problem of social productivity mentioned in the book shows that utopia has not gotten rid of the characteristics of class exploitation. Living in the Middle Ages, More knew the evils of society and what society needed, but he could not find a way to achieve socialism. 莫尔敢于同封建统治者作斗争，他是一个人文主义者。莫尔不是革命者，也无意激起人民或者被统治阶级的革命行动。书中提及的解决社会生产力问题的奴隶系统说明乌托邦没有摆脱阶级剥削的特征。身处中世纪，莫尔知道社会弊端，了解社会需要什么，但是他无法找到实现社会主义的途径。
