Definition: The truth of the conclusion is assumed by the premises
The truth of the conclusion is assumed by the premises. Often, the conclusion is simply restated in the premises in a slightly different form. In more difficult cases, the premise is a consequence of the conclusion.
Show that in order to believe that the premises are true we must already agree that the conclusion is true. (Barker: 159, Cedarblom and Paulsen: 144, Copi and Cohen: 102, Davis: 33)
