If our history teaches us anything, it is this lesson: so far as the economic potential of our nation is concerned, the believers in the future of America have always been the realists. I count myself as one of this company.

The stupid speak of the past, the wise of the present, and fools of the future.

The past is a rich resource on which we can draw in order to make decisions for the future, but it does not dictate our choices. We should look back at the past and select what is good, and leave behind what is bad.

A nation that forgets its past has no future.

Everyone can recognize history when it happens. Everyone can recognize history after is has happened; but only the wise man knows at the moment what is vital and permanent, what is lasting and memorable.

The attempt to combine wisdom and power has only rarely been successful and then only for a short while.
