Clearly, if a man holds a self-contradictory belief, then his belief cannot be rational, for there can be no set of evidence sufficient to justify it. This is most apparent when the self contradictory belief is a belief in a conjunction, (e.g., a belief that p & ~p), rather than when it is a non-conjunctive self-contradictory belief, e.g. a belief that red is not a color.
