Chapter 11 第十一章

第十一章

　　三十輻共一轂，當其無，有車之用。埏埴以為器，當其無，有器之用。鑿戶牖以為室，當其無，有室之用。故有之以為利，無之以為用。

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.

The thirty spokes unite in the one nave; but it is on the empty
space (for the axle), that the use of the wheel depends. Clay is
fashioned into vessels; but it is on their empty hollowness, that
their use depends. The door and windows are cut out (from the walls)
to form an apartment; but it is on the empty space (within), that its
use depends. Therefore, what has a (positive) existence serves for
profitable adaptation, and what has not that for (actual) usefulness.
