Thirty spokes join at a single hub;
its use depends on the hole in the center.
Clay is formed into a pot;
its use depends on the hole in the center.
Doors and windows make a building;
its use depends on the hole in the center.

Thus, though something may have value,
it is the nothing that makes it useful.

 


chapter notes:

This chapter has no deliberate misappropriation at all. Only the title (“The Empty Disk”) suggests a computerish relevance.
