Some of the writers expressed a blind faith that we can still learn from our previous mistakes, while others approached the subject with a surprising resentment of our past.

resentment 是名词，来自动词 resent（怨恨、愤恨），表示"愤恨、不满"的情绪。resent 由前缀 re-（表示"再次"）和拉丁词根 sentire（感觉）组成，字面意思是"再次感受到（负面情绪）"。resentment 指因感到不公平或受伤害而产生的持续怨恨情绪。
