"Proving" that something is true by taking your conclusion as one of your premises, usually done implicitly rather than explicitly. Few people are fooled by [[ShapedLikeItself having your conclusion as your only premise]], as in "Joe is mad at Jill, therefore Joe is mad at Jill.". Such arguments are called ''[[http://en.wikipedia.org/wiki/Tautology_%28rhetoric%29 tautologies]]'' and are valid, and they're sound if the premises are true, but they're utterly meaningless. Put broadly, this fallacy applies to any argument where one or more premises are at least as contentious as the conclusion itself, and for the same reasons, such as:

* In ''VisualNovel/UminekoWhenTheyCry'', accepting the red text as only speaking the truth requires you believe both that Beatrice is being honest and that the red text speaks only the truth when statements like "The red text speaks only the truth!" come up. [[spoiler: Well, at least that's the case until we see Battler attempt to use the red to say something that turns out to be untrue.]] That said, it does happen to be true: Anything said in red is at worst misleading.

* In the days of Website/{{Usenet}}, in a football forum, one poster postulated that you need a great coach to win a Super Bowl. He then defined a "great coach" as one who had won a Super Bowl.

** The [[RealLife Roundworld]] inspiration for this is mentioned in ''Discworld/TheScienceOfDiscworld'': Eratosthenes proved the circumference of the Earth was 252,000 stadia. This is very accurate, assuming you use the right kind of stadium (there were several different measurements of that name). How do we know which one he used? Well, if the circumference of the Earth is 252,000 stadia, then...

[[AC: Literature]]
* The ''Literature/{{Discworld}} Companion'' entry for the Ephebian philosopher Expletius says that while he proved the Disc was 10,000 miles in diameter, ''all'' philosophers had their own "proof" of the Disc's size giving wildly different numbers, but "they turned out to be wrong". With ''how'' it "turned out" they were wrong carefully elided, the suggestion is we're taking the ''actual'' diameter of the Disc as established, and judging the proofs based on that.

* A classic Bill Mauldin political cartoon from the early 1960s features an American soldier standing in a field of large cartoon mushrooms, a shout-out to the conical hats worn by Asian field workers and guerrillas, explaining to a comrade the challenge of ground combat in Vietnam: "You got your mushrooms and your toadstools. The mushrooms are harmless, the toadstools will kill you. You'll know it's a toadstool if it kills you."[[note]]A botanist would call shenanigans on this, pointing out that there are no toadstools, there are only poisonous (and harmless) mushrooms.[[/note]]

See also NoTrueScotsman. If both parties accuse each other of begging the question, then it's a philosophical impasse -- no one can agree on a common set of premises; compare ValuesDissonance. See also TautologicalTemplar, who believes that since they are good, everything they do is justified.
