Begging the Question.It doesn't mean what you think it means.
Begging the question — from the Latin
petitio principii — is a logical fallacy; it means assuming your conclusion in the course of your argument. If you say "Everything in the Bible must be true, because it's the word of God," you're taking your conclusion for granted. If you say "The defendant must be guilty because he's a criminal," you're doing the same. It's a kind of circular logic. The conclusion may be true or false, but you can't prove something by assuming it's true.
This is very different from
raising the question, though people are increasingly using the phrase that way. It's sloppy, and should be avoided. Here, for instance, is a piece from
The Times (London), 30 Nov. 2004:
The behaviour of ministers is a matter for prime ministers, who appoint and dismiss them. But this begs the question of who should find out what has gone wrong on behalf of a prime minister.
No it doesn't. It
raises the question; it
prompts the question; perhaps it
forces us to ask the question; maybe this question
begs for an answer. But it doesn't
beg the question.
