Big Lie
Frequently misattributed to Joseph Goebbels, the oft-cited "Big Lie Theory" appears instead to have been Adolf Hitler's explanation for how people came to believe that Germany lost World War I in the field -- a "big lie" which Hitler attributed to Jewish influence on the press.
Hitler writes in "Mein Kampf" (James Murphy translation, page 134):
"All this was inspired by the principle - which is quite true in itself -
that in the big lie there is always a certain force of credibility; because
the broad masses of a nation are always more easily corrupted in the deeper
strata of their emotional nature than consciously or voluntarily; and thus
in the primitive simplicity of their minds they more readily fall victims to
the big lie than the small lie, since they themselves often tell small lies
in little matters but would be ashamed to resort to large-scale falsehoods.
It would never come into their heads to fabricate colossal untruths, and
they would not believe that others could have the impudence to distort the
truth so infamously. Even though the facts which prove this to be so may be
brought clearly to their minds, they will still doubt and waver and will
continue to think that there may be some other explanation. For the grossly
impudent lie always leaves traces behind it, even after it has been nailed
down, a fact which is known to all expert liars in this world and to all who
conspire together in the art of lying. These people know only too well how
to use falsehood for the basest purposes.
"From time immemorial. however, the Jews have known better than any others
how falsehood and calumny can be exploited. Is not their very existence
founded on one great lie, namely, that they are a religious community, where
as in reality they are a race? And what a race! One of the greatest thinkers
that mankind has produced has branded the Jews for all time with a statement
which is profoundly and exactly true. Schopenhauer called the Jew "The Great Master of Lies". Those who do not realize the truth of that statement, or do not wish to believe it, will never be able to lend a hand in helping Truth to prevail."
