The presence of absence is a curious thing. From Lao Tze through to logical incompleteness as a function of the indefinite extensibility of all non-trivially sophisticated complex information and energy-processing (i.e. natural, computational) systems.
What is really interesting, though, is that the absence of overarching structure and patterned grammar or organisational unity is an inverse approximation to the logical self-containment that biological systems have been leveraging for billions of years, effortlessly, and that human beings are still bumbling around in the shallows of.
That which does not exist makes that which does more useful. Simultaneously, that which does not exist represents the sum total and structural unification of all that does. It is a subtle matter that can not be easily explained.
