苟或非义而动,背理而行；以恶为能,忍作残害；阴贼良善,暗侮君亲；慢其先生,叛其所事；诳诸无识,谤诸同学；虚诬诈伪,攻讦宗亲；刚强不仁,狠戾自用；是非不当,向背乖宜；虐下取功,谄上希旨；受恩不感,念怨不休；轻蔑天民,扰乱国政；
But sometimes there is someone who behaves without righteousness,and moves against rationality,who mistakes evil for ability,and inflicts injury on others,who secretly defames the virtuous,and behind their backs slanders his ruler or his parents,who ignores those born before him,and disobeys his masters...这一段中who ignores those born before him 应该翻译成“慢其先生”,请问这里的born是什么意思?born这个词有没有弄错?
who ignores those born before him 表示“慢其先生”，这里的“先生”应当是“教师、师傅”的意思，翻译成"those born before him”
