begging the question

(also called Petitio Principii, this term is sometimes used interchangeably with Circular Reasoning): If writers assume as evidence for their argument the very conclusion they are attempting to prove, they engage in the fallacy of begging the question. The most common form of this fallacy is when the first claim is initially loaded with the very conclusion one has yet to prove. For instance, suppose a particular student group states, "Useless courses like English 101 should be dropped from the college's curriculum." The members of the student group then immediately move on in the argument, illustrating that spending money on a useless course is something nobody wants. Yes, we all agree that spending money on useless courses is a bad thing. However, those students never did prove that English 101 was itself a useless course--they merely "begged the question" and moved on to the next "safe" part of the argument, skipping over the part that's the real controversy, the heart of the matter, the most important component. Begging the question is often hidden in the form of a complex question (see below).
