A lot of fake quotes attributed to Adolf Hitler exist. Their creation was partly Allied War propaganda, and most of the rest were created by Jewish groups that apparently never tire of manufacturing them.
Among the more famous of these fake quotes has Hitler saying such things as these:
"If you repeat a lie enough, it becomes the truth."
"Make the lie big, make it simple, keep saying it, and eventually they will believe it."
Adolf Hitler never endorsed the use of Big-Lie propaganda. These fake quotes are the result of a gerrymandering and context-stripping of what Hitler said in MEIN KAMPF. I'll quote the relevant passages, from which the fake quotes were stitched together.
*** Excerpt from MEIN KAMPF, Chapter 3 ***
By far the greatest share in their political "education," which in this case is most aptly designated by the word "propaganda," falls to the account of the press. It is foremost in performing this "work of enlightenment" and thus represents a sort of school for grown-ups.
This instruction, however, is not in the hands of the state, but in the claws of forces which are in part very inferior.
In Vienna as a very young man I had the best opportunity to become acquainted with the owners and spiritual manufacturers of this machine for educating the masses.
At first I could not help but be amazed at how short a time it took this great evil power within the state to create a certain opinion even where it meant totally falsifying profound desires and views which surely existed among the public.
In a few days a ridiculous episode had become a significant state action, while, conversely, at the same time, vital problems fell a prey to public oblivion, or rather were simply filched from the memory and consciousness of the masses.
Thus, in the course of a few weeks it was possible to conjure up names out of the void, to associate them with incredible hopes on the part of the broad public, even to give them a popularity which the really great man often does not obtain his whole life long; names which a month before no one had even seen or heard of, while at the same time old and proved figures of political or other public life, though in the best of health, simply died as far as their fellow men were concerned or were heaped with such vile insults that their names soon threatened to become the symbol of some definite act of infamy or villainy.
We must study this vile Jewish technique of emptying garbage pails full of the vilest slanders and defamations from hundreds and hundreds of sources at once, suddenly and as if by magic, on the clean garments of honourable men, if we are fully to appreciate the entire menace represented by these scoundrels of the press.
There is absolutely nothing one of these spiritual robber-barons will not do to achieve his unsavoury aims.
He will poke into the most secret family affairs and not rest until his truffle searching instinct digs up some miserable incident which is calculated to finish off the unfortunate victim.
But if, after the most careful sniffing, absolutely nothing is found, either in the man's public or private life, one of these scoundrels simply seizes on slander, in the firm conviction that despite a thousand refutations something always sticks and, moreover, through the immediate and hundredfold repetition of his defamations by all his accomplices, any resistance on the part of the victim is in most cases utterly impossible; and it must be borne in mind that this rabble never acts out of motives which might seem credible or even understandable to the rest of humanity. God forbid!
While one of these scum is attacking his beloved fellow men in the most contemptible fashion, the octopus covers himself with a veritable cloud of respectability and unctuous phrases, prates about "journalistic duty" and suchlike lies, and even goes so far as to shoot off his mouth at committee meetings and congresses—that is, occasions where these pests are present in large numbers—about a very special variety of "honour," to wit, the journalistic variety, which the assembled rabble gravely and mutually confirm.
These scum manufacture more than three quarters of the so-called "public opinion," from whose foam the parliamentarian Aphrodite arises.
*** Excerpt from MEIN KAMPF, Chapter 10 ***
It required the whole bottomless falsehood of the Jews and their Marxist fighting organization to lay the blame for the collapse on that very man who alone, with superhuman energy and will power, tried to prevent the catastrophe he foresaw and save the nation from its time of deepest humiliation and disgrace.
By branding Ludendorff as guilty for the loss of the World War they took the weapon of moral right from the one dangerous accuser who could have risen against the traitors to the fatherland. In this they proceeded on the sound principle that the magnitude of a lie always contains a certain factor of credibility, since the great masses of the people in the very bottom of their hearts tend to be corrupted rather than consciously and purposely evil, and that, therefore, in view of the primitive simplicity of their minds they more easily fall a victim to a big lie than to a little one, since they themselves lie in little things, but would be ashamed of lies that were too big.
Such a falsehood will never enter their heads and they will not be able to believe in the possibility of such monstrous effrontery and infamous misrepresentation in others; yes, even when enlightened on the subject, they will long doubt and waver, and continue to accept at least one of these causes as true. Therefore, something of even the most insolent lie will always remain and stick — a fact which all the great lie-virtuosi and lying-clubs in this world know only too well and also make the most treacherous use of.
The foremost connoisseurs of this truth regarding the possibilities in the use of falsehood and slander have always been the Jews; for, after all, their whole existence is based on one single great lie, to wit, that they are a religious community while actually they are a race — and what a race! One of the greatest minds of humanity has nailed them forever as such in an eternally correct phrase of fundamental truth: he called them "the great masters of the lie." And anyone who does not recognize this or does not want to believe it will never in this world be able to help the truth to victory.
