This has become more difficult in a world where change and growth seem to tower beyond the control and even the judgment of men.  We must work to provide the knowledge and the surroundings which can enlarge the possibilities of every citizen.

The American covenant called on us to help show the way for the liberation of man.  And that is today our goal.  Thus, if as a nation there is much outside our control, as a people no stranger is outside our hope.

Change has brought new meaning to that old mission.  We can never again stand aside, prideful in isolation.  Terrific dangers and troubles that we once called “foreign” now constantly live among us.  If American lives must end, and American treasure be spilled, in countries we barely know, that is the price that change has demanded of conviction and of our enduring covenant.

Think of our world as it looks from the rocket that is heading toward Mars.  It is like a child’s globe, hanging in space, the continents stuck to its side like colored maps.  We are all fellow passengers on a dot of earth.  And each of us, in the span of time, has really only a moment among our companions.

How incredible it is that in this fragile existence, we should hate and destroy one another.  There are possibilities enough for all who will abandon mastery over others to pursue mastery over nature.  There is world enough for all to seek their happiness in their own way.

Our Nation’s course is abundantly clear.  We aspire to nothing that belongs to others.  We seek no dominion over our fellow man, but man’s dominion over tyranny and misery.

But more is required.  Men want to be a part of a common enterprise—­a cause greater than themselves.  Each of us must find a way to advance the purpose of the Nation, thus finding new purpose for ourselves.  Without this, we shall become a nation of strangers.

UNION AND CHANGE

The third article was union.  To those who were small and few against the wilderness, the success of liberty demanded the strength of union.  Two centuries of change have made this true again.

No longer need capitalist and worker, farmer and clerk, city and countryside, struggle to divide our bounty.  By working shoulder to shoulder, together we can increase the bounty of all.  We have discovered that every child who learns, every man who finds work, every sick body that is made whole—­like a candle added to an altar—­brightens the hope of all the faithful.

So let us reject any among us who seek to reopen old wounds and to rekindle old hatreds.  They stand in the way of a seeking nation.

Let us now join reason to faith and action to experience, to transform our unity of interest into a unity of purpose.  For the hour and the day and the time are here to achieve progress without strife, to achieve change without hatred—­not without difference of opinion, but without the deep and abiding divisions which scar the union for generations.
