1940s, Fourth Inaugural Address (1945)
Context: 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 — 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.

Il est certain que pendant le seizième siècle, dans les années qui le précédèrent et le suivirent, l'empoisonnement était arrivé à une perfection inconnue à la chimie moderne et que l'histoire a constatée.

1900s, Address at Providence (1901)
Context: We are passing through a period of great commercial prosperity, and such a period is as sure as adversity itself to bring mutterings of discontent. At a time when most men prosper somewhat some men always prosper greatly; and it is as true now as when the tower of Siloam fell upon all alike, that good fortune does not come solely to the just, nor bad fortune solely to the unjust. When the weather is good for crops it is also good for weeds.
