If no thing then no thing.
If thing then thing and no thing.
Thus thing.
In other words, if there is only no thing, then there is nothing to know there is no thing.
But if there is thing, then there is thing to both know there is thing, and know there is no thing.
Thus to express fullness, there must be thing.
