Intellectual freedom begins when one says with Socrates that he knows that he knows nothing, and then goes on to add: Do you know what you don’t know and therefore what you should know? If your answer is affirmative and humble, then you are your own teacher, you are making your own assignment, and you will be your own best critic. You will not need externally imposed courses, nor marks, nor diplomas, nor a nod from your boss . . . in business or in politics. (from the essay The Last Don Rag)
