There was a time when it was common knowledge that the world was flat and the sun, moon, stars and all the planets revolved around it. There was a time when everyone was sure that demons caused illness and drought. Today we have made discoveries that disprove those “facts” of long ago and we have replaced them with new “facts” accepted by most of us on this planet. But just how accurate are these things we hold as common knowledge? Will they, too, be disproved one day? Remember that there is no proof that something is correct, only the inability to prove that it is no…for now!

I am reminded that back in the 1970’s we were told by the “experts” that we were entering a mini ice age.  Well, that has morphed into global warming and again into climate change.

There was a time when it was commonly accepted that some ethnic groups were not as intelligent as others, or that lightning never strikes the same place twice.  We know today that both of these are untrue.

My point is not to attempt to dispel current beliefs or argue today’s contested topics.  I simply wish to point out that before we blindly accept “common knowledge” as fact we should ask questions, do our own research and think independently…like a free person!
