Fallacies: Begging the Question (narrow sense)

This video introduces the fallacy known as "begging the question". It focuses on a form of the fallacy that is also known as "circular reasoning".

Thank you! This is the best explanation of Begging the Question fallacy that I've seen on YouTube!

[PaleMist]

Another way to word the definition of  "begging the question", "circular logic", aka "circular reasoning": the use of logic or reason in which a premise is equivalent to or dependent upon the conclusion. FYI there are some cases of circular logic that are completely fair and must be used at all times when a person is thinking (and by "thinking" I mean any reason processing, not exclusively practical reasoning).

Great explanation(asserting the same thing in the premise & conclusion)

I've watched several of your videos on logic fallacy. Well done instruction. But, I've noticed that whenever you give an example of the fallacy in words, it is the conservative, religious, pro life, creationist, etc. side that is committing the fallacy and the liberal, atheist, pro choice, evolutionist, etc. side that has the sound argument. Do these educational videos have a second political purpose?

I don't see how your last example is one of circular reasoning.
1. Murder is wrong
2. assumed premise: abortion is murder
Conclusion: abortion is wrong.

Seems while the assumed premise can be challenged it is a valid logical structure. What am I missing?

[KaosEspada]

i understand how "murder is morally wrong. this being the case, then abortion must also be morally wrong" is making the assumption that abortion is murder but i dont understand is how the 2nd premise in your restatement makes the argument question begging? if someone doesnt initailly believe premise 2 then justification for that premise would be given to persuade others of the truth of the premise. i dont see how a premise has to be believed by both parties for it to be non question begging?

Love your videos... Isn't the Yaris model made by Toyota?

[Sisyphus]

I take issue with your example at 4:30. What you have identified is an enthymeme. There is nothing particularly circular about an enthymeme particularly when the assumed premise is so obviously assented to that the premise does not need stating. Such an assumption depends on jurisdiction and cultural habits of the people involved. If someone rejects the conclusion they may very well accept the hidden premise and reject the explicit premise. In other words there are cases in which murder is not morally wrong. For example killing baby Hitler. In any case, there is an obvious hidden premise and it is that hidden premise that means it isn't an example of begging the question.

"begging the question" is said here to be "calling out a logical falicy" . Which begs the question, is that truly what begging the question is?

[sinthalis]

You're giving a very good example of begging the question with that statement. I doubt you're doing that to instruct, however.

But what about this approach?

[verifiedufos]

isn't the abortion one a reasoning by analogy?

[ifhesamanandshesamanimhugh]

Is begging the question the same as a presupposition?

[lifelearnerlloyd]

Great - objective should be to show how to identify this particular fallacy. Good!

[MinePurpose]

I’m just gonna use the term circular reasoning cuz arguing is hard enough without having to explain this shit to people.

[timrussell]

I, too, enjoy your videos. I only wish that fewer of your examples were based on religious controversies because many of my students are religious. Otherwise, I would share these with them as examples of logical fallacies. Such controversies, unfortunately, shut the door to rational discourse.

[TheaDragonSpirit]

Are you not saying the same thing in the common use and in logic.

By someone being circular doesn't that mean it makes you beg the question or inspire the question on whether or not what they say could be true? Even if the way they say it isn't logical?

For example if I say that something is true because I said it is true?

Isn't that inspiring the question as to why they think it is true? Or if there is any truth to their argument. And in this isn't this similar to the common meaning?

[pseudothinker]

All humans are mortal.
Socrates is a human.
Therefore, Socrates is mortal.

Is this begging the question too?

[stevenspiker]

I think you have begged the question when you say that there is nothing wrong with using "beg the question" to mean "raise the question." I think your second premise rates low on the plausibility scale. 1. People commonly use "beg the question" to mean "raise the question." 2. If something is commonly used, that makes it all right. Conclusion: Therefore there is nothing wrong with using the term "beg the question" to mean raise the question.

100% of arguments where spherical and or rotating earth is the conclusion will beg the question.
