We Americans of today， together with our allies， are passing through a period of supreme test.It is a test of our courage， of our resolve， of our wisdom and our essential democracy.If we meet that test successfully and honorably， we shall perform a service of historic importance which men and women and children will honor throughout all time.As I stand here today， having taken the solemn oath of office in the presence of my fellow countrymen—in the presence of our God—I know that it is America"s purpose that we shall not fail.
AIn the days and in the years that are to come we shall work for a just and honorable peace， a durable peace， as today we work and fight for total victory in war. We can and we will achieve such a peace.We shall strive for perfection.We shall not achieve it immediately—but we still shall strive.BWe may make mistakes—but they must never be mistakes which result from faintness of heart or abandonment of moral principle.
I remember that my old schoolmaster， Dr. Peabody， said， in days that seemed to us then to be secure and untroubled：“Things in life will not always run smoothly.Sometimes we will be rising toward the heights—then all will seem to reverse itself and start downward.The great fact to remember is that the trend of civilization itself is forever upward；that a line drawn through the middle of the peaks and the valleys of the centuries always has an upward trend.”
Our Constitution of 1787 was not a perfect instrument；it is not perfect yet. But it provided a firm base upon which all manner of men， of all races and colors and creeds， could build our solid structure of democracy.
And so today， in this year of war，1945，we have learned lessons—at a fearful cost—and we shall profit by them. We have learned that we cannot live alone， at peace；that our own well-being is dependent on the well-being of other nations far away.CWe have learned that we must live as men， not as ostriches， nor as dogs in the manger.
