Reality

There were European philosophers who argued that we create the world with our minds. That's paranoia, but maybe all they meant was that we perceive the world from a human point of view. Of course,  if they said it that way, without exaggeration, who would buy their books?

The Nazis believed that if you told a big lie often enough, people would believe it.  The lie would become real. Later we had post-structuralists who argued that there are no facts and no genuine truths. The Bush folks mocked Democrats for their belief in a "fact-based world." And so on. 

Right now we have the Trumpfolk telling us that the Democrats do not have a genuine impeachment committee working in the House. They seem to believe that if every Republican says this three times, the impeachment process will vanish.    

The Republicans are in for a surprise when Trump gets impeached.

As Peter Viereck, a conservative thinker of the last century, wrote, "Reality is that which, when you don't believe in it, doesn't go away."
