We will go to the moon. We will go to the moon and do other things, NOT because they are easy but because they are HARD.

In a very real sense, it will not be one man going to the moon it will be an entire nation. For all of us must work to put him there.

Children are the world's most valuable resource and its best hope for the future

Our children and grandchildren are not merely statistics towards which we can be indifferent

i truly believe when the dust passes over our leveled cities, the only thing that will matter is what we contribute to humankind

Mankind must put an end to war, or war will put an end to mankind... War will exist until that distant day when the conscientious objector enjoys the same reputation and prestige that the warrior does today.
