One readily recognized example of question begging goes thus:
“God must exist.”
“How do you know?”
“Well, the Bible says so.”
“But why should I believe the Bible?”
“Because the Bible was written by God.”
And we all laugh at the dumb theist, who may have other good reasons for his faith, as he clearly doesn’t realize how silly that argument sounds. Now, claiming that God exists is a bold claim; therefore, the evidence needs to be good if we are going to accept it from an intellectual standpoint. In Monday’s Guardian, one author makes another bold claim: “Liberty is not what it once was.” Forgetting for the moment that he holds John Stuart Mill as the philosopher of liberty, I found the argument a little wanting in general, and I couldn’t help but think of the ‘God’ conversation above when I ran into this section of text:
Mill’s libertarian philosophy is based on two precepts … The first principle asserts that “all errors which (a man) is likely to commit against advice and warning, are far outweighed by the evil of allowing others to constrain him to what they deem his good”. Only cranks believe that now. If it were a generally held view, we would not prohibit the use of recreational drugs or require passengers in the back seats of motor cars to wear safety belts.
Were the paragraph above simply a description of common public opinion there would be nothing fallacious at play — aside from his unwarranted use of the word crank, that is, which appears to signify “someone not agreeing with the majority” for this author. (You know, like all those “cranks” who voted against Bush in ‘04.) But, alas, description is replaced with prescription when the text above is implicitly used as evidence later:
The philosophy for our time ought to concern a consensus about civilised conduct, not extol irresponsible individualism. And it ought to be based on a definition of liberty that is far more meaningful to the majority of mankind than Mill’s notion that freedom is no more than the absence of restraint.

The following conversation then took place in my mind:
Daniel: “This doesn’t seem philosophically sound to me.”
G: “You mean you’d prefer a Mill-style freedom?”
Daniel: “Yes; I think I would.”
G: “But that’s preposterous, for the first thing to go would be seat-belt safety laws and anti-drug laws.”
Daniel: “Great! . . .Oh, there’s a problem?”
G: “Well, it’s obvious that only cranks think that, so you’ll need to get with the times, if you want to propose a serious version of liberty. . .”
