#utility

We join spokes together in a wheel, but it is the center hole that makes the wagon move.

We shape clay into a pot, but it is the emptiness inside that holds whatever we want.

We hammer wood for a house, but it is the inner space that makes it livable.

Any idea upon which we can ride, any idea that will carry us prosperously from any one part of our experience to any other, is true for just so much.

All men know the usefulness of the useful, but nobody knows the usefulness of the useless.
