We live in a world of diverse cultures, and we know very little about social engineering and how to ‘build nations.’ And when we cannot be sure how to improve the world, hubristic visions pose a grave danger.
There is no reason inherent in the real resources available to us why we cannot move rapidly within the next two or three years to a state of genuine full employment.
We know we cannot plant seeds with closed fists. To sow, we must open our hands.
When we cannot hope to win, it is an advantage to yield.
We cannot fight new wars with old weapons.
We cannot even recollect the actions of our infancy, our childhood is like something written on a slate and rubbed off.
Knowledge is not eating, and we cannot expect to devour and possess what we mean. Knowledge is recognition of something absent; it is a salutation, not an embrace.
If we attend continually and promptly to the little that we can do, we shall ere long be surprised to find how little remains that we cannot do.
We cannot be sure of having something to live for unless we are willing to die for it.
We cannot seek achievement for ourselves and forget about progress and prosperity for our community… Our ambitions must be broad enough to include the aspirations and needs of others, for their sakes and for our own.
