We have a duty to speak even more clearly and courageously, to work hard, and to keep fighting this battle while the strength is still in us.... Even those of us who have reached and passed our 70th birthdays cannot afford to rest on our oars and spend the rest of our lives dozing in the Florida sun. The times call for courage. The times call for hard work. But if the demands are high, it is because the stakes are even higher. They are nothing less than the future of liberty, which means the future of civilization.
