但这河水，虽然流得那么慢，却还有一种流动的感觉， 给人一种世事无常的惆怅。

How should he not know love, he, who has discovered all elements of human existence in their transitoriness, in their meaninglessness, and yet loved people thus much, to use a long, laborious life only to help them, to teach them!

他怎么会不懂得爱呢，他已经发现了人类存在的所有要素的短暂，在它们的无意义中，却如此热爱人们，用漫长而艰苦的生命来帮助他们，教导他们！
