Begging the question (or petitio principii) is a logical fallacy (mistake, error) in which the proposition (a point to be discussed or proved) to be proved is assumed implicitly (directly) or explicitly (indirectly) in the premises (assumptions, postulates). Begging the question is related to the fallacy known as circular argument, circulus in probando or circular reasoning. The first known definition in the West is by the Greek philosopher Aristotle around 350 BC, in his book Prior Analytics.
The phrase is also commonly used to indicate that some crucial questions are relevant to the topic at hand. For example: It begs the questions, (1) how did he do it, and (2) why? This use, however, has nothing to do with the fallacy.
Question 1:
Now I'm sure Jack stole my wrist watch. But it begs the questions, (1) why did he do it, and (2) how? I have been giving him a handsome pocket money. What thing made him to do such a cheap act.
Am I understanding it correctly?
"That begs the question" is an appropriate reply when a given argument depends on what it is trying to support, and as a result, the proposition is being used to prove itself. For example: "Why am I the boss? It's because I call the shots around here." "Of course I had a reason, or I wouldn't have done it." "I didn't steal it. I'm no thief!"
Question 2:
S/he is not using the line
The begs the question in her/his reply. Rather s/he is simply starting with ''Why am I the boss?''
To cast abortion as a solely private moral question,…is to lose touch with common sense: How human beings treat one another is practically the definition of a public moral matter. Of course, there are many private aspects of human relations,
but the question whether one human being should be allowed fatally to harm another is not one of them. Abortion is an inescapably public matter.
Question 3:
Is the phrase
whether one human being should be allowed fatally to harm another alluding to killing of fetus? Moreover, I would have written,
whether one human being should be allowed to harm another fatally, instead. Is my way also correct?
To beg the question does not mean "to raise the question." (e.g. "It begs the question, why is he so dumb?") This is a common error of usage made by those who mistake the word "question" in the phrase to refer to a literal question. Sadly, the error has grown more and more common with time, such that even journalists, advertisers, and major mass media entities have fallen prey to "BTQ Abuse."
Question 4:
To me
beg the question also means
to raise a question. The given text would make a perfect sense even if the expression
it beg the questions is substituted with
it raises the questions.
Now I'm sure Jack stole my wrist watch. But it raises the questions, (1) why did he do it, and (2) how? I have been giving him a handsome pocket money. What thing made him to do such a cheap act.
