十一章

　　三十辐共一毂，当其无，有车之用。埏埴以为器，当其无，有器之用。凿户
牖以为室，当其无，有室之用。故有之以为利，无之以为用。

Chapter 11. Tools

Thirty spokes meet at a nave;

Because of the hole we may use the wheel.

Clay is moulded into a vessel;

Because of the hollow we may use the cup.

Walls are built around a hearth;

Because of the doors we may use the house.

Thus tools come from what exists,

But use from what does not.
