《荀子·天论》
慎子对在后服从的一面有所认识，但对在前引导的一面却毫无认识；老子对委曲忍让的一面有所认识，但对积极进取的一面却毫无认识；墨子对齐同平等的一面有所认识，但对等级差别的一面却毫无认识；宋子对寡欲的一面有所认识，但对多欲的一面却毫无认识。
老子有见于诎，无见于信。墨子有见于齐，无见于畸。宋子有见于少，无见于多。
Shenzi realized the aspect of service in later times but not the aspect of guidance in earlier times; Laozi realized the aspect of concession but not the aspect of initiative; Mozi realized the aspect of equality but not the aspect of difference; Songzi realized the aspect of abstinence but not the aspect of desire.
