For the first time in the history of mankind, one generation literally has the power to destroy the past, the present and the future, the power to bring time to an end.

If today there is a proper American "sphere of influence" it is this fragile sphere called earth upon which all men live and share a common fate--a sphere where our influence must be for peace and justice.

The great challenge which faces us is to assure that, in our society of big-ness, we do not strangle the voice of creativity, that the rules of the game do not come to overshadow its purpose, that the grand orchestration of society leaves ample room for the man who marches to the music of another drummer.

Leadership in today's world requires far more than a large stock of gunboats and a hard fist at the conference table.

Much of our American progress has been the product of the individual who had an idea; pursued it; fashioned it; tenaciously clung to it against all odds; and then produced it, sold it, and profited from it.

To be realistic today is to be visionary. To be realistic is to be starry-eyed.

The essence of statesmanship is not a rigid adherence to the past, but a prudent and probing concern for the future.
