"Beyond the drumfire of daily crisis, therefore, there is arising the outlines of a robust and vital world community, founded on nations secure in their own independence, and united by their allegiance to world peace. It would be foolish to say that this world will be won tomorrow, or the day after. The processes of history are fitful and uncertain and aggravating. There will be frustrations and setbacks. There will be times of anxiety and gloom. The specter of thermonuclear war will continue to hang over mankind; and we must heed the advice of Oliver Wendell Holmes of "freedom leaning on her spear" until all nations are wise enough to disarm safely and effectively. Yet we can have a new confidence today in the direction in which history is moving. Nothing is more stirring than the recognition of great public purpose. Every great age is marked by innovation and daring--by the ability to meet unprecedented problems with intelligent solutions. In a time of turbulence and change, it is more true than ever that knowledge is power; for only by true understanding and steadfast judgment are we able to master the challenge of history. If this is so, we must strive to acquire knowledge--and to apply it with wisdom."
