Expedience Quotes (2 quotes)
Gather round while I sing you of Wernher von Braun,
A man whose allegiance
Is ruled by expedience.
Call him a Nazi, he won't even frown.
“ha, Nazi sch-mazi,” says Wernher von Braun.
Stanza from song, 'Wernher von Braun' on record That Was the Year That Was (Jul 1965). Collected in script to musical, Tom Foolery: The Words and Music of Tom Lehrer (1986), 35.
The way of pure research is opposed to all the copy-book maxims concerning the virtues of industry and a fixed purpose, and the evils of guessing, but it is damned useful when it comes off. It is the diametrical opposite of Edison’s reputed method of trying every conceivable expedient until he hit the right one. It requires, not diligence, but experience, information, and a good nose for the essence of a problem.
Letter to Paul de Kruif (3 Aug 1933), as quoted in Nathan Reingold, Science in America: A Documentary History 1900-1939 (1981), 409.
In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
(1987) --
