Dust can't be eradicated - only moved around.
If you knew of someone who "knew the Truth about Life and Man", would you ask him to tell it to you?
If you knew YOU "knew the Truth", would you tell it?
If you knew such "a someone", would it be Crime, to not "spread the good word?" Would one be "required" by certain Laws, to make others aware of that person? Or, would it be "required" to conceal from all, that fact - even yourself (eventually)?
Truth, either, only moved around.
