[ How have you shown the following statement to be false?]

We just went over that.. (Dyslexic question)

Saying that a person is "chasing his tail" does not show that his statement is false.

Perhaps this will help explain why hosepipe's assertion of circular reasoning was a successful debunking of the assertion:

Petitio Principii

I. Petitio Principii: (circular reasoning, circular argument, begging the question) in general, the fallacy of assuming as a premiss a statement which has the same meaning as the conclusion.

[many examples at the source]

III. The reason petitio principii is considered to be a fallacy is not that the inference is invalid (because any statement is indeed equivalent to itself), but that the argument can be deceptive. A statement cannot prove itself. A premiss must have a different source of reason, ground or evidence for its truth from that of the conclusion.
