Maybe the solution is not so much accepting complexity, as understanding simplicity.
Consider that galaxies are energy radiating out, as structure coalesces in.
The emotional appetites and desires of the digestive and respiratory systems seeking and circulating energy drive us on, while the central nervous system sorts through the forms and information, to direct our actions.
Society is the organic social energies driving it, while the civil and cultural forms give it structure and stability.
One is centrifugal, while the other is centripetal. So there will aways be those pushing the boundaries and those enforcing the structures. Too far one direction and it's anarchy. Too far the other direction and it's tyranny.
We fluctuate in the middle. Which is where complexity is greatest.
As for complexity versus simplicity, there are reasons the people leading armies are called generals and specialist is about one rank above private.
Maybe our problem is it has become the age of specialization and the effect is this global Tower of Babel.
We are linear, goal oriented creatures in a cyclical, circular, reciprocal, feedback generated reality.
