Wikipedia: Flat Earth
The flat Earth model is an archaic conception of Earth’s shape as a plane or disk. Many ancient cultures subscribed to a flat Earth cosmography, including Greece until the classical period, the Bronze Age and Iron Age civilizations of the Near East until the Hellenistic period, India until the Gupta period (early centuries AD), and China until the 17th century. That paradigm was also typically held in the aboriginal cultures of the Americas, and the notion of a flat Earth domed by the firmament in the shape of an inverted bowl was common in pre-scientific societies.
 
Wikiquote: Franklin D. Roosevelt
Franklin Delano Roosevelt (30 January 1882 – 12 April 1945), and and often referred to by his initials FDR, was an American statesman and political leader who served as the President of the United States from 1933 to 1945

First Inaugural Address (1933)
These dark days will be worth all they cost us if they teach us that our true destiny is not to be ministered unto but to minister to ourselves and to our fellow men.
This is preeminently the time to speak the truth, the whole truth, frankly and boldly. Nor need we shrink from honestly facing conditions in our country today. This great Nation will endure as it has endured, will revive and will prosper. So, first of all, let me assert my firm belief that the only thing we have to fear is fear itself — nameless, unreasoning, unjustified terror which paralyzes needed efforts to convert retreat into advance. In every dark hour of our national life a leadership of frankness and vigor has met with that understanding and support of the people themselves which is essential to victory.
. Part of this is often misquoted as “We have nothing to fear but fear itself,” most notably by Martin Luther King, Jr. in his I’ve Been To The Mountaintop speech. Similar expressions were used in ancient times, for example by Seneca the Younger (Ep. Mor. 3.24.12): scies nihil esse in istis terribile nisi ipsum timorem (“You will understand that there is nothing dreadful in this except fear itself”), and by Michel de Montaigne: “The thing I fear most is fear”, in Essays (1580), Book I, Ch. 17.
