“Each of us guard a gate of change that can only be opened from the inside.”

“No one can persuade another to change. Each of us guards a gate of change that can only be opened from the inside. We cannot open the gate of another, either by argument or by emotional appeal.”

“It is very risky. But each time a child opens a book, he pushes open the gate that separates him from Elsewhere.”

“It's common to go from 'crashing the gate' to guarding it.”

“When Muslim radicals and fundamentalists look at the West, they see only the openness that makes us, in their eyes, decadent and promiscuous. They see only the openness that has produced Britney Spears and Janet Jackson. They do not see, and do not want to see, the openness - the freedom of thought and inquiry - that has made us powerful, the openness that has produced Bill Gates and Sally Ride. They deliberately define it all as decadence. Because if openness, women's empowerment, and freedom of thought and inquiry are the real sources of the West's economic strength, then the Arab-Muslim world would have to change. And the fundamentalists and extremists do not want to change.”

“Each of us is an impregnable fortress that can be laid waste only from within.”
