Do you have both theTao Te Ching, along with the Zhuangzi? I read .. a few years ago, that they unearthed a readable text of both, writing on silk and still mostly legible, from 2nd Century BC. That's the earliest semi-complete compilation .. although they have found smaller portions from as early as 4th Century BC.
What's the origin of your translation. Back, looooooooong time ago, when I was reading such things ... I read a few different translations. Some of them differed a goodly amount from some of the others.
