What's the worst argument you can think of?
One of my favorites is from a Theodore Sturgeon science fiction story in which it's claimed that faster than light communication must be possible because even though stars are light years apart, a person can look from one to another in a moment.
I don't know about you, but bad logic makes my stomach hurt, especially on first exposure.
This seems rather odd-- what sort of physical connection might that be?
Also, I'm not sure how common the experience is, though a philosophy professor did confirm it for himself and (by observation) his classes. He mentioned one of the Socratic dialogues (sorry, I can't remember which one) which is a compendium of bad arguments and which seemed to have that effect on his classes.
So, how did you feel when you read that bit of sf hand-waving? If your stomach hurt, what sort of stomach pain was it? Like nausea? Like being hit? Something else? If you had some other sensory reaction, can you describe it?
For me, the sensation is some sort of internal twinge which isn't like nausea.
Anyway, both for examination and for the fun of it, please supply more bad arguments.
I think there are sensory correlates for what is perceived to be good logic (unfortunately, they don't tell you whether an argument is really sound)-- kinesthesia which has to do with solidity, certainty, and at least in my case, a feeling that all the corners are pinned down.
Addendum: It looks as though I was generalizing from one example. If you have a fast reaction to bad arguments and it isn't kinesthetic, what is it?
Interestingly, my reaction wasn't negative. Instead, my curiosity was stimulated, and I immediately set myself the task of figuring out what was wrong with it. (Turned out to be easy, of course.)
On a larger scale, I've found the exercise of going through a certain 427 pages of wrongness, and coming to precise understandings of the mistakes, to be strangely satisfying (and informative). Perhaps it could be compared to the feeling of satisfaction a repairman might get from fixing a broken machine.
On the other hand, when (the very same) bad arguments are presented in this manner, I get so enraged I can barely stand to look. (Dark techniques really grate on me when they're used in an attempt to persuade people of something I know to be incorrect; and if you're wrong, you darn well better not be sanctimonious about your wrong answer.)
I also suspect that if I had encountered the above sci-fi argument in context, where the incorrect deduction would either have been used to support a further, important, wrong conclusion, or would just have indicated carelessness on the part of the author or character, I would have been annoyed.
Sturgeon (the book is The Cosmic Rape) wanted a galactic scale group mind which could think quickly. I don't know if the book would have been better without the argument. IIRC, it was written in omniscient third person, and that argument was merely stated rather than given to a character.
