We have the capacity to think morally, we have the capacity to act morally, and to be altruistic or benevolent.

The most altruistic behavior of all, giving your life to help another, can be explained in cold-blooded evolutionary terms.

最利他的行为，就是为他人牺牲自己，这也可以用毫无人情味的进化论来解释。

耶鲁公开课 - 心理学导论课程节选

So, evolution works at a level of the genes and because of that it could give rise to animals that are themselves altruistic.

进化论起作用的是我们的基因,因此进化论能产生,有利他主义的动物。

耶鲁公开课 - 心理学导论课程节选

And they're altruistic because they act to preserve other animals that share the same genes.

说它们利他，是因为它们会保护其他动物,和它们有同样基因的动物。

And I want to focus particularly on emotions that generate kind or altruistic behavior.

我想特别讲解能让人产生善意,利他主义行为的情感。

耶鲁公开课 - 心理学导论课程节选

This gives rise to some emotion including emotions that could be viewed as moral emotions, like guilt and anger, and again, grounds altruistic behavior in an evolutionary perspective.

这就产生了情绪,包括被视为道德情绪的情绪，例如内疚和愤怒，再一次，这种对利他行为的解释,也是从进化论的角度出发的。

Animals that are altruistic even to the point of dying to help another, those genes will, under some circumstances, be preserved over the genes of people who are less caring.

有强烈利它主义的动物,甚至为其他动物牺牲自己，这些基因在某些情况下，就会被保存下来,而那些不关心他人的基因则不会。

耶鲁公开课 - 心理学导论课程节选

Hence, selfish genes will lead to altruistic animals because, to the extent that evolution operates at the level of the genes, there's no hard and fast distinction between your own body and someone else's body.

所以，自私基因会导致利他行为，从这个意义上说,进化在基因层面进行，你自己的身体和别人的身体,没有严格差别。
