I walked up to the great German philosopher Wittgenstein and observed, “What a bunch of morons the people of the Middle Ages must have been to have looked every morning at the dawn and to have thought what they were seeing was the sun going around the earth. But every school kid knows the earth goes around the sun and it doesn’t take too many brains to understand that.”
Wittgenstein responded: “I wonder what it would have looked like if the sun was indeed going around the earth.”
The point is the dawn would have looked exactly the same. We see what our knowledge tells us to see; what you think the universe is, and how you react to that along with everything you do, depends entirely on what you know; and when that knowledge changes, for you the universe changes; and that is as true for the whole of society as it is for the individual—we all are what we know today. What we knew yesterday was different and so were we.
This is humbling if you understand the implications. If you don’t understand, then it’s probably just nonsense.
