At left is something that theologian Dietrich Bonhoeffer said shortly before he was executed by the Third Reich for his protest against the fascist regime.

Most of us have had the thought he expressed here. We may be talking with an old friend who went to a prestigious college and showed when we were young considerable intelligence, who now, when it comes to world politics is now limited to the talking points of Newsmax and Fox News.

How did this happen?

Nobody knows, but, over the last couple of decades, this subject has caught the attention of neuroscientists who believe that liberals’ and conservatives’ brains are internally connected differently from each other.

As an example, tests show that the brain activity of self-identified liberals and conservatives are vastly different when experimental subjects are shown photographs of potentially threatening animals, like spiders and snakes.  Those who think of themselves as conservatives have brain activity that show fear and hatred, while self-described liberals’ brains suggest that they perceive such animals as simply members of the planet on which we live.

Maybe no one is to blame; perhaps we just live in different worlds of consciousness.

Those hankering for a great read on this subject, albeit fiction, should check out Ian McEwan’s masterpiece “Saturday.”

Are Our Brains “Wired” Differently?
