It's a fact – everyone is ignorant in some way or another. Ignorance is our deepest secret. And it is one of the scariest things out there, because those of us who are most ignorant are also
the ones who often don't know it or don't want to admit it.
Here is a quick test:
If you have never changed your mind about some fundamental tenet of your belief, if you have never questioned the basics, and if you have no wish to do so, then you are likely ignorant. Before it is too late, go out there and find someone who, in your opinion, believes, assumes or considers certain things very strongly and very differently from you, and just have a basic honest conversation. It will do both of you good.
