Diplomacy and defense are not substitutes for one another. Either alone would fail.

Let every nation know, whether it wishes us well or ill, that we shall pay any price, bear any burden, meet any hardship, support any friend, oppose any foe to assure the survival and the success of liberty.

I think the success of any school can be measured by the contribution the alumni make to our national life.

We do not seek the unanimity that comes to those who water down all issues to the lowest common denominator - or to those who conceal their differences behind fixed smiles - or to those who measure unity by standards of popularity and affection, instead of trust and respect. We are allies. This is a partnership, not an empire. We are bound to have differences and disappointments - and we are equally bound to bring them out into the open, to settle them where they can be settled, and to respect each other's views when they cannot be settled.

If this nation is to be wise as well as strong, if we are to achieve our destiny, then we need more new ideas for more wise men reading more good books in more public libraries.

The supreme reality of our time is the vulnerability of our planet.

Persons are judged to be great because of the positive qualities they possess, not because of the absence of faults.
