“The American city should be a collection of communities where every member has a right to belong. It should be a place where every man feels safe on his streets and in the house of his friends. It should be a place where each individual’s dignity and self-respect is strengthened by the respect and affection of his neighbors. It should be a place where each of us can find the satisfaction and warmth which comes from being a member of the community of man. This is what man sought at the dawn of civilization. It is what we seek today.”

1960s, Inaugural address (1965)
Context: Liberty was the second article of our covenant. It was self-government. It was our Bill of Rights. But it was more. America would be a place where each man could be proud to be himself: stretching his talents, rejoicing in his work, important in the life of his neighbors and his nation. 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.

Context: I say this in order to impress upon you, if you are not already so impressed, that no small matter should divert us from our great purpose. There may be some irregularities in the practical application of our system. It is fair that each man shall pay taxes in exact proportion to the value of his property; but if we should wait before collecting a tax to adjust the taxes upon each man in exact proportion with every other man, we should never collect any tax at all. There may be mistakes made sometimes; things may be done wrong while the officers of the Government do all they can to prevent mistakes. But I beg of you, as citizens of this great Republic, not to let your minds to carried off from the great work we have before us. This struggle is too large for you to be diverted from it by any small matter.
