To give you a quick example of nature creating incentives that lead to individuals pursuing their own interests that result in the advancement of the whole, look at sex and natural selection. Nature gave us one hell of an incentive to have sex in the form of the great pleasure it provides, even though the purpose of having sex is to contribute to the advancement of the DNA. That way, we individually get what we want while contributing to the evolution of the whole.
为了给你一个简单的例子，说明大自然创造激励措施，导致个人追求自己的利益，从而导致整体的进步，看看性别和自然选择。尽管性行为的目的是为了促进 DNA 的进步，但大自然却以性行为带来的巨大愉悦为我们提供了极大的动力。这样，我们就可以单独得到我们想要的东西，同时为整体的进化做出贡献。
