"Don't you see? There isn't any real progress...there is only one large circle that we march in, around and around, each of us with our own little picture in front of us-our own little mirage of what we think is the future."

"It isn't a circle-it is simply a long that reaches into infinity. And because we cannot see the end, we also cannot see how it changes. And it is very odd but those who see the changes-who dream, who will not give up- are called idealists...and those who only see the circle- we call them the 'realists.'"
