When a lie is told it starts out small and usually has the purpose of keeping the truth concealed. However, if a lie is told to a mass of people as a cover-up of sorts, it is only a matter of time before the truth gets out. As the fabrication grows, it begins to morph and spread like a disease. One lie follows with multiple corresponding lies to maintain the "accuracy" of the deception. Soon, keeping this web of lies alive becomes of vital importance, but simply in fear of the consequences that would come with the uncovering of the truth. That being the case, I do in fact agree with the quote. Replacing a falsehood with the truth soon enough becomes an attempt to prove the truth itself as false, as shown in The Village and The Crucible when the creation of a lie turns into a battle between those hiding the secret and the truth itself.
