Pseudoproof (Fallacy) |
There are encounters in arguments in which a reader will find material that may appear at first to be a proof but really is not a proof at all -- it is a pseudoproof, or what is commonly called a fallacy. Fallacies lead an audience astray, they distort and distract, they represent inadequate reasoning or nonreasoning, and they either exaggerate or oversimplify a claim instead of prooving it.
