I'm a bit tired of people constantly misusing the phrase "begging the question" or "begs the question."
This is not correct usage:
"Mary Jane switched coaches in the middle of the season which seemed to upset her racing a bit. This begs the question - why did she switch coaches in the first place?"
Begging the question is something completely different. It is a logical fallacy somewhat related to circular reasoning. It is when the conclusion of an argument is hidden in an assumption of a premise in the argument.
Here is a famous example (from Richard Whately in 1862):
"To allow every man an unbounded freedom of speech must always be, on the whole advantageous to the State, for it is highly conducive to the interests of the community that each individual should enjoy a liberty perfectly unlimited of expressing his sentiments."
The conclusion of his argument says exactly the same thing as the premise. It is just hidden through synonymy. The speaker seems to be making a point, though. In reality his conclusion begs the question, as the premise (which starts at "for") does not prove anything but simply restates the conclusion.
Anyway, I don't expect people to stop incorrectly using the expression "begs the question," but I would at least like people to know that it is used incorrectly.
