Once you tell a lie, the truth is your enemy; and every truth connected to that truth, and every ally of truth in general; all of these you must oppose, to protect the lie. Whether you're lying to others, or to yourself.
If the deceiver and the deceived are the same person, either the deception or being deceived failed - but the original condition was that both succeeded. Thus a contradiction. Claims it is possible to lie to yourself are often (and perhaps in this case) a 'you know what I mean' shortcut that are fruitful to question.
