“What we know is not much. What we do not know is immense.”
“It is not so much what we know that is important, as what we are and what 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.”
“To know that we know what we know, and that we do not know what we do not know, that is true knowledge.”
“What we know is not much. What we don't know is enormous.”
“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.”
