'''Begging the question''', which goes by the technical name '''petitio principii''', is a [[logical fallacy]] that occurs when an [[argument]] implicitly assumes its conclusion.
  
==Example==

For example, consider the following argument:
 +
# Q: How do you know the [[Bible]] is correct?
 +
# A: Because it was written by [[God]].
  
"How do you know [[the Bible]] is correct?"<br>
+
The answer begs the question, "How do you know that God wrote it?" (Note that if the answer is, "Because it says so in the Bible," then this is an example of [[circular reasoning]].)
"Because it was written by [[God]]."<br>

This begs the question "How do you know that god wrote it?"

(Note that if the Christian answers the latter with "Because it says in the Bible that he did" then this is an example of [[circular reasoning]].)

Often, people say "beg the question" when they really mean "raise the question", e.g., "You say that theism makes more sense then atheism, but that just begs the question of which religion I should join."

People often refer to "begging the question" when they really simply mean "raising another question". For example:

: "You say that [[theism]] makes more sense than [[atheism]], but that just ''begs the question'' of which [[religion]] I should choose to believe."

This is not an appropriate use of the term, since the question being raised is not implicit in the preceding statement.
  
"Begging the question" means "assuming one's conclusion". This is not the same as raising further questions.

For more information, see the Wikipedia article:

Begging the question, which goes by the technical name petitio principii, is a logical fallacy that occurs when an argument implicitly assumes its conclusion.

For example, consider the following argument:

  1. Q: How do you know the Bible is correct?
  2. A: Because it was written by God.

The answer begs the question, "How do you know that God wrote it?" (Note that if the answer is, "Because it says so in the Bible," then this is an example of circular reasoning.)

Grammar note

People often refer to "begging the question" when they really simply mean "raising another question". For example:

"You say that theism makes more sense than atheism, but that just begs the question of which religion I should choose to believe."

This is not an appropriate use of the term, since the question being raised is not implicit in the preceding statement.
