Premise: But the power of words is such that I contend their impact is totally lost if not treated  somehow, there is a difference between  Someone had written shit on the wall  and  Some asshole had written shit on the wall : the writer of the former has more credibility; the writer of the latter was, very likely, the very asshole who had written shit on the wall.

Hypothesis: No one wrote shit on the wall.
Relation: contradiction
