Begging the Question

Begging the Question, also referred to by its Latin name, Petitio Principii, or often called circular reasoning, is a fallacy in which the basis for a question relies on the question being true.

The phrase "Begging the Question" is frequently used incorrectly to suppose an argument, when in fact it is a specific logical fallacy.

An example of begging the question would be as follows:

"Do you know why dogs are the friendliest animal? Because all the friendliest animals I've met have been dogs."
