For physical fitness is not only one of the most important keys to a healthy body; it is the basis of dynamic and creative intellectual activity. The relationship between the soundness of the body and the activities of the mind is subtle and complex. Much is not yet understood. But we do know what the Greeks knew: that intelligence and skill can only function at the peak of their capacity when the body is healthy and strong; that hardy spirits and tough minds usually inhabit sound bodies.

Five score years ago the ground on which we here stand shuddered under the clash of arms and was consecrated for all time by the blood of American manhood. Abraham Lincoln, in dedicating this great battlefield, has expressed, in words too eloquent for paraphrase or summary, why this sacrifice was necessary. Today, we meet not to add to his words nor to amend his sentiment but to recapture the feeling of awe that comes when contemplating a memorial to so many who placed their lives at hazard for right, as God gave them to see right. Among those who fought here were young men who but a short time before were pursuing truth in the peaceful halls of the then new University of Notre Dame. Since that time men of Notre Dame have proven, on a hundred battlefields, that the words, "For God, For Country, and For Notre Dame," are full of meaning. Let us pray that God may grant us the wisdom to find and to follow a path that will enable the men of Notre Dame and all of our young men to seek truth in the halls of study rather than on the field of battle."

We are a great and strong country — perhaps the greatest and strongest in the history of the world. But greatness and strength are not our natural right. They are not gifts which are automatically ours forever. It took toil and courage and determination to build this country — and it will take those same qualities if we are to maintain it. For, although a country may stand still, history never stands still. Thus, if we do not soon begin to move forward again, we will inevitably be left behind. And I know that Americans today are tired of standing still — and that we do not intend to be left behind. But effort and courage are not enough without purpose and direction. For, as Socrates told us, "If a man does not know to what port he is sailing, no wind is favorable."
