“How do we know what we believe we know?”
“And of how we never really know someone, no matter how much we want to believe that we do.”
“The true test of character is not how much we know how to do, but how we behave when we don't know what to do.”
“Curious creatures we mortals are-how we do not know what we want, or how to get it if we do.”
“To know that we know what we know, and to know that we do not know what we do not know, that is true knowledge.”
“What we think or what we know or what we believe is in the end of little consequence. The only thing of consequence is what we do”
