Someone used this phrase in the correct way, which got me thinking that I need to have this “correct way” written down. Interesting topic.
In classical rhetoric and logic, begging the question is an informal fallacy that occurs when an argument’s premises assume the truth of the conclusion, instead of supporting it. It is a type of circular reasoning: an argument that requires that the desired conclusion be true. This often occurs in an indirect way such that the fallacy’s presence is hidden, or at least not easily apparent.
It occurred to on re-reading this that the above needs an example. Which I found here
Paranormal activity is real because I have experienced what can only be described as paranormal activity.
The claim, “paranormal activity is real” is supported by the premise, “I have experienced what can only be described as paranormal activity.” The premise presupposes, or assumes, that the claim, “paranormal activity is real” is already true.
And now back to the Wikipedia page.
In modern vernacular usage, however, begging the question is often used to mean “raising the question” or “suggesting the question”. Sometimes it is confused with “dodging the question”, an attempt to avoid it.
The phrase begging the question originated in the 16th century as a mistranslation of the Latin petitio principii, which actually translates to “assuming the initial point”.
