Lao Tze saidthis about seeing the hole:Thirty spokes are joined together in a wheel,but it is the center holethat allows the wheel to function.We mold clay into a pot,but it is the emptiness insidethat makes the vessel useful.We fashion wood for a house,but it is the emptiness insidethat makes it livable.We work with the substantial,but the emptiness is what we use.—from the Tao Te Ching, translated for public domain by j. h. mcdonaldIt’s easier to critique something that exists than to create from nothing.
