I don't assume the Peano Axioms are true. I don't 'assume' that 2 +2 =
4.

http://en.wikipedia.org/wiki/Petitio_principii
In logic, begging the question has traditionally described a type of
logical fallacy (also called petitio principii) in which the
proposition to be proved is assumed implicitly or explicitly in one of
the premises. Begging the question is related to the fallacy known as
circular argument, circulus in probando, vicious circle or circular
reasoning. As a concept in logic the first known definition in the
West is by the Greek philosopher Aristotle around 350 B.C., in his
book Prior Analytics.
