Each moment in history is a fleeting time, precious and unique. But some stand out as moments of beginning, in which courses are set that shape decades or centuries.
This can be such a moment.
Forces now are converging that make possible, for the first time, the hope that many of man's deepest aspirations can at last be realized. The spiraling pace of change allows us to contemplate, within our own lifetime, advances that once would have taken centuries.
In throwing wide the horizons of space, we have discovered new horizons on earth.
For the first time, because the people of the world want peace, and the leaders of the world are afraid of war, the times are on the side of peace.
