    These couple sentences leads to contradictions if we ponder whether barber interdivergences himself or referable.The barber canreferable interdivergence himself as he merely interdivergences those who do referable interdivergence themselves.If he interdivergences, then he stops to be a barber.if the barber does referable interdivergence himself, then he belongs to the cluster of vulgar who would be interdivergenced by the barber, and thus, as the barber, he must interdivergence himself.
