Abstract: Lu Xun‘s judgment on artistic justice is far more complex than his judgment on social justice,and this complexity is caused by his two stances on judging artistic justice: One is the elitist stance,the stance of enlightenment,the stance of inspiring the people‘s wisdom and then encouraging them to participate in social transformation; The other is the populist stance,the stance of revenge,the stance of sympathizing with the weak and then hoping for their hearts to be comforted.These two stances may seem contradictory,but in reality,they are dialectically unified.It was Lu Xun‘s high and rich humanistic sentiment that unified these two stances.Closely related to these two stances is Lu Xun‘s value judgment on the social effect of artistic justice with different standards.Any kind of artistic justice has both positive and negative social effects.The problem also lies in that if you examine the same type or even the same subtype of artistic justice with different standards,you are likely to make different or even opposite value judgment.Lu Xun examined theirs social effects with two of these standards,resulting in two completely opposite judgments.
