The emptiness of man though it resembles fullness, and seems all of a piece, actually is made of nothings, bits of emptiness, like the sponge, empty when filled, swollen like the sponge, with air, with empty air; it has copied its very structure from the sponge, it is made up in clusters, of bubbles, of non-grapes. Man’s empty fullness is like a sack filled with sponges, is filled with emptiness: man’s emptiness, or swollen emptiness, or the emptiness that swells by being empty.

― Joao Cabral De Melo Neto
