 The requirement that self-deceivers holds contradictory beliefs raises the ‘static’ paradox, since it seems to pose an impossible state of mind, namely, consciously believing that p and ~p at the same time. As deceiver, she must believe that ~p, and, as deceived, she must believe that p. Accordingly, the self-deceiver consciously believes that p and ~p. But if believing both a proposition and its negation in full awareness is an impossible state of mind to be in, then self-deception as it has traditionally been understood seems to be impossible as well.
