We suggest you turn to the Tao Teh Ching:
11. The Value of Non-existence Thirty spokes together make one hub. Where the nothing is, lies the cart's use. Throwing clay to deem:make a utensil; Where the nothing is, lies the utensil's use. Sculpting windows and doors to deem:make a room; Where the nothing is, lies the room's use. So where we deem having it as 'beneficial.' We deem 'use' to consist in lacking it. -- tr. C. Hansen
