The purpose of education...is to create in a person the ability to look at the world for [herself or] himself, to make [her or] his own decisions, to say to [herself or] himself this is black or this is white, to decide for [herself or] himself whether there is a God in heaven or not. To ask questions of the universe, and then learn to live with those questions is the way [a person] achieves her or his own identity. But no society is really anxious to have that kind of person around. What societies really, ideally want is a citizenry which will simply obey the rules of society. If a society succeeds in this, that society is about to perish. The obligation of anyone who thinks of herself or himself as responsible is to examine society and try to change it or to fight it - at no matter what risk. This is the only hope society has. This is the only way societies change.
