I will be teaching a class at my church over the summer covering logical fallacies. I want to start each class by having students do a cold reading of arguments employing the fallacies the class will cover. I'm asking members here to help me out by linking debates that employ the following fallacies, which I intend to cover in the first class:

1. Begging the Question/Circular Reasoning " This can include sub-fallacies like Loaded Words or Appeal to Nature.
2. Special Pleading
3. Non Sequitur

When linking a debate, please tell me the fallacy you are linking about, the round number the fallacy occurs in, and the person committing the fallacy (Pro or Con). Something like the format below.

- Link to Debate
- Question Begging
- Round 3
- Con
- Optional Remarks

Christians using these fallacies is preferred as I believe people learn better when forced to critique material they agree with. I fully anticipate at least a couple of you linking to me own debates. So be it. I know there are couple debates I should have lost, though I'll never admit which ones. :)

I don't need a lot of links since I'll only have time to read two or three samples, so if even a handful of you link one debate, I should have plenty of material to work with. I really do appreciate it. If this works out well, I will ask for links to other types of fallacies for the other classes in the series. I plan to cover three or four fallacies in each class.

Most common one I see is the slippery slope.

I've seen quite a few of them in this debate.

Example: My opponent said "Agnosticism also illigitimately equivilates 'will not know,' with 'cannot know."

This is a slippery slope because he wrongly assumes the position that Agnostics choose to deny the proof of a God, without giving the pre-supposed proof in his argument. He made an argument in which I had no way of arguing without accepting that God exists, which defeats the purpose of my position.

Considering your teaching this in a church, I am not sure how likely you are to use my example, but maybe you can convince them to be open minded ;-)

As I stated, I'm happy to critique Christian views. I even prefer it. I appreciate your slipper slope entry, but I plan to touch on that fallacy near the end of my course. For this first class, I want to focus on the ones I mentioned in the OP. Slippery Slope is a bit tougher to identify than question begging, which is why I'm starting with the latter. I am attempting to order the fallacies into a learning curve that adults with full time jobs and kids can digest.

I wouldn't use debates, because by definition they:

1) Are usually concealed and difficult to spot. Debates are aiming to not produce these fallacies, so they are not easily spotted.

2) People find fallacies where there are not, and don't spot them where they are. This is why with examples of actual debaters you very rarely find them.

http://www.nizkor.org...

This is the best way of finding fallacies and examples.

A good example for hasty generalisations:

Smith, who is from England, decides to attend graduate school at Ohio State University. He has never been to the US before. The day after he arrives, he is walking back from an orientation session and sees two white (albino) squirrels chasing each other around a tree. In his next letter home, he tells his family that American squirrels are white.

The problem of course is that no true is that stupid.

Bill: "You know, those feminists all hate men."
Joe: "Really?"
Bill: "Yeah. I was in my philosophy class the other day and that Rachel chick gave a presentation."
Joe: "Which Rachel?"
Bill: "You know her. She's the one that runs that feminist group over at the Women's Center. She said that men are all sexist pigs. I asked her why she believed this and she said that her last few boyfriends were real sexist pigs. "
Joe: "That doesn't sound like a good reason to believe that all of us are pigs."
Bill: "That was what I said."
Joe: "What did she say?"
Bill: "She said that she had seen enough of men to know we are all pigs. She obviously hates all men."
Joe: "So you think all feminists are like her?"
Bill: "Sure. They all hate men."

A logical fallacy is based on the principal of a flawed argument.

Non sequitur isn't a fallacy. It's just a statement that a fallacy has happened. It just means "that doesn't follow." If the logic is invalid, then the conclusion doesn't follow, and it's a non-sequitur.

I'll try to dig up some threads where I had a nice conversation with v3nesl, there's bound to be a treasure trove of fallacies there.

I want real debates as examples precisely because the fallacies are difficult to find. The class will not center on these examples. Rather, I will use them to get people thinking and analyzing. The actual course material will use very simple examples to communicate the nuances of each fallacy, but I want exposure to real arguments because that's what people encounter in the world.

I am aware that non-sequitur is not a logical fallacy, but it is still a mistake people make when arguing. Therefore, it's something worth including in the course.

I'll check back periodically to see if anyone has provided examples, but based on the feedback so far, I'm getting the sense people here are not all that interested in helping.

It's a logical fallacy, but it's just a very broad one that includes many others like; undistributed middle term, non causa pro causa, ignorantio elenchi, post hoc, hasty generalization, etc. In fact it could be said that all formal fallacies are types of non-sequiturs.

"Non sequitur (Latin for "it does not follow"), in formal logic, is an argument in which its conclusion does not follow from its premises.[1] In a non sequitur, the conclusion can be either true or false, but the argument is fallacious because there is a disconnection between the premise and the conclusion. All formal fallacies are special cases of non sequitur." http://www.princeton.edu...(logic).html

I don't think it's about not being interested, it's more about people not having examples strait off the top of their head, or keeping a list of debates that contain (the said) logical fallacies. If you give people a couple of months or so, to site examples as they come across them, I'm sure people would have more examples for you.
That being said, by when do you need this stuff?
Also, maybe you could post a list of all the fallacies that you will be teaching, in order to give people more time.

Finally, I was thinking that perhaps you could record the classes and post them on DDO, I certainly would be interested. Everyone seems to be doing "shows" on DDO these days, it would be nice to have at least one serious one that actually directly deals with debating, this is after all a debate site. Plus it will probably spark some lively and interesting discussions.

The point about the broadness of Non Sequitur is well taken. I think I had "Jumping to Conclusions" in mind, but now that I ponder it further, I agree that there are many other possible fallacies that could be at play here. I'll rethink how I approaching this term, if at all. I am, after all, teaching this to a lay audience and I don't want to muddy the waters for the sake of one fallacy.

I really like the link to the Republican debates. People relate to examples like these because they might have been suckered by them in real life. I didn't want to just offer trite examples because we can too easily dismiss them as "mistakes other people make."

I've gotten some good ideas here. Thanks.

Logical fallacies from the written media:
books, newspapers, magazines, newsletters, fundraising letters, etc.. There is enough context so that the arguer's intention is not misrepresented, but excluded information irrelevant to the specific argument. You can probably find more context, I.E., the original source in full, by googling either the source, or the quoted section/text:
http://www.fallacyfiles.org...
http://www.orange-papers.org...

These are similar, but uses video clips as well,

I'll keep an eye out for logical fallacies on this site, as I come across them.

Debate: Richard Dawkins is a gratuitously unpleasant man. http://www.debate.org...

Fallacy: non-sequitur

R2: Pro argues "Richard Dawkins wants to convert everyone to atheism"

Comment: "Gratuitously unpleasant" refers to the manner of presentation, not the content of what is presented. So what it is that Dawkins is promoting does not bear upon whether he is pleasant of not. (Similarly, atheists might not like the Rev. Billy Graham's fundamentalist message, but Graham is nonetheless pleasant.) The debate is interesting, I think, because Pro went on to show that Dawkins was unpleasant, but failed to show the unpleasantness was gratuitous.
