The strange thing about us humans is that we sometimes learn to see something we hold as truth in a new light. We learned something new, and looking back, we find it hard to understand how we could ever have been so foolish. But then, we keep on living and believing many of our other and sometimes older beliefs. Are we so hardwired to believe what is in us despite the knowledge that we have been wrong many times? Intelligence might be just a trick we dumb animals are only good at when we play.
