Marco Polo describes a bridge, stone by stone.
"But which is the stone that supports the bridge?" Kublai Khan asks.
"The bridge is not supported by one stone or another,"
Marco answers, "but by the line of the arch that they form."
Kublai Khan remains silent, reflecting. Then he adds:
"Why do you speak to me of the stones? It is only the arch that matters to me."
Polo answers: "Without stones there is no arch."
-p.82, "Invisible Cities"; Italo Calvino
Thirty spokes share the wheel's hub;
It is the center hole that makes it useful.
Shape clay into a vessel;
It is the space within that makes it useful.
Cut doors and windows for a room;
It is the holes which make it useful.
Therefore profit comes from what is there;
Usefulness from what is not there.
ch. 11, "Tao Te Ching"; Lao Tsu
