把这一句，留给此刻的你
Introspection and preserved writings give us far more insight into the ways of past humans than we have into the ways of past dinosaurs. For that reason, I'm optimistic that we can eventually arrive at convincing explanations for these broadest patterns of human history.
自省和保存下来的文字让我们对过去人类的生活方式有了更多的了解，而不是我们对过去恐龙生活方式的了解。因此，我乐观地认为，我们最终能够对这些人类历史上最广泛的模式做出令人信服的解释。
