“There are good citizens and bad citizens in every class as in every locality, and the attitude of decent people toward great public and social questions should be determined, not by the accidental questions of employment or locality, but by those deep-set principles which represent the innermost souls of men.”

1780s
Context: Such being the impressions under which I have, in obedience to the public summons, repaired to the present station; it would be peculiarly improper to omit in this first official Act, my fervent supplications to that Almighty Being who rules over the Universe, who presides in the Councils of Nations, and whose providential aids can supply every human defect, that his benediction may consecrate to the liberties and happiness of the People of the United States, a Government instituted by themselves for these essential purposes: and may enable every instrument employed in its administration to execute with success, the functions allotted to his charge. In tendering this homage to the Great Author of every public and private good, I assure myself that it expresses your sentiments not less than my own; nor those of my fellow-citizens at large, less than either. No People can be bound to acknowledge and adore the invisible hand, which conducts the Affairs of men more than the People of the United States. Every step, by which they have advanced to the character of an independent nation, seems to have been distinguished by some token of providential agency. And in the important revolution just accomplished in the system of their United Government, the tranquil deliberations and voluntary consent of so many distinct communities, from which the event has resulted, cannot be compared with the means by which most Governments have been established, without some return of pious gratitude along with an humble anticipation of the future blessings which the past seem to presage.

1961, The City upon a Hill speech
Context: During the last sixty days, I have been at the task of constructing an administration. It has been a long and deliberate process. Some have counseled greater speed. Others have counseled more expedient tests. But I have been guided by the standard John Winthrop set before his shipmates on the flagship Arbella three hundred and thirty-one years ago, as they, too, faced the task of building a new government on a perilous frontier. "We must always consider," he said, "that we shall be as a city upon a hill — the eyes of all people are upon us." Today the eyes of all people are truly upon us — and our governments, in every branch, at every level, national, state and local, must be as a city upon a hill — constructed and inhabited by men aware of their great trust and their great responsibilities. For we are setting out upon a voyage in 1961 no less hazardous than that undertaken by the Arbella in 1630. We are committing ourselves to tasks of statecraft no less awesome than that of governing the Massachusetts Bay Colony, beset as it was then by terror without and disorder within. History will not judge our endeavors — and a government cannot be selected — merely on the basis of color or creed or even party affiliation. Neither will competence and loyalty and stature, while essential to the utmost, suffice in times such as these.

Nicomachean Ethics

Views on civil rights declared in a written statement requested by Robert W. Kenny, read during fund raising luncheon at the Biltmore Hotel, in Los Angeles, in the summer of 1938, quoted in Lawyers Guild Review Vol. 13-14 (1953), p. 47; he mentions Frank Hague, who had declared earlier in the year:
Context: I believe the preservation of our civil liberties to be the most fundamental and important of all our governmental problems, because it always has been with us and always will be with us and if we ever permit those liberties to be destroyed, there will be nothing left in our system worthy of preservation. They constitute the soul of democracy. I believe that there is grave danger in this country of losing our civil liberties as they have been lost in other countries. There are things transpiring in this country today that are definitely menacing our future; among which are the activities of Mayor Hague and other little Hagues throughout the country. These activities are so basically wrong and so menacing to our institutions that every citizen and particularly every public official should oppose them to the limit of their strength.
