道德经英文版（无用第十一）
~{ 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。~}
11. Continence
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 distinctions seem to contain,
But their use is to transform.
