Our memories are not ironclad representations of reality, but subjective perceptions.

我们的记忆并不是对现实的铁定描述，而是主观认知。

The problem with basing morality on emotions is of course that emotions are inextricably  linked with individual, subjective perception influenced by things like our cultural background, temperament, upbringing, and so on.

将道德建立在情感的基础上的问题当然在于，情感与受文化背景、气质、成长等因素影响的个人主观认知密不可分。
