"At the foundation of well-founded belief lies belief that is not founded," observed Ludwig Wittgenstein, "Any reasonable person behaves like this."  Ludwig Wittgenstein was one of the greatest philosophers of the twentieth century.  His insights always strike to core of who we are.
     And this quote is no exception.  All of us, every last one of us, relies ultimately on beliefs which have no foundation.  Can we prove that we are here?  Can we prove that two plus two is four?  No:  we simply accept it.
     Hence, if ever we question someone's belief as being ungrounded, let us always examine our own starting points and ask ourselves:  how do we know this?
     You may be surprised at your honest answer.  Granted, although we all tend to construct our own reality, we rarely know what reality really is.
     After all, we're only human.
     And where did we come from?
