爱是唯一能拯救我们自己的东西。

The truth is rarely pure and never simple.

We die containing a richness of lovers and tribes, tastes we have swallowed, bodies we have plunged into and swum up as if rivers of wisdom, characters we have climbed into as if trees, fears we have hidden in as if caves.

科学是一种思维方式，远不止是一堆知识。
