egoists

While some individualists are egoists, they usually do not argue that selfishness is inherently good.

虽然有些个人主义者，利己主义者，他们通常不认为自私是人性本善。

Human beings are such egoists that even the weaker thinks that somehow he is going to win.

人类是那样一种自我中心者，连弱者都认为他有赢的可能。

But you are not alone in this world. There are other beings of whom you must think. You must not be egoists.

这是再好不过的，但你们不是单身汉，要想到其他的人，不要自私。
