Flatland, Cognitive Paleolithic & More Dimensions

My life objective is to get us on the path to cognitive expanse, out of the Cognitive Paleolithic. What does that mean and how can we get there? Could the answer lie in “dimensionality”?

Clues may be in that famous little book, Edwin Abbott’s old, fun thought experiment called Flatland. Carl Sagan explains Flatland brilliantly in only a few minutes here, my much less brilliant, two-second explanation is just imagine living in a totally flat, 2D world and you’re visited by someone from the 3rd dimension!

Spoiler alert: the the visitor from the 3rd dimension breaks the brain of the citizen of the 2D world. It’s well worth your time to watch the above video or read the book to understand why.

A few Einstein biographies credit Flatland as helping him conceptualize his theories.

Could we experience the world in significantly more dimensions? Can we create a higher dimensional language or communication protocol?

Are these even the right question?

What is happening in the brain when we imagine higher or lower dimensions?

How can we as as species get better at this imagination exercise? Would higher dimensionality help us become Future Literate (something the UN cares a lot about too), so that we may better understand, prepare, and survive an increasingly complex future?
