What is "logical"? Two people are having an argument about gun control. For example, this latest Oregon shooter. person "A" says this is another
example of a lack of gun control, and logically, as this incident proves, we need to ban AR-15s. Person "B" says this is a perfect example of gun
control, and had the mall not "banned" the presence of guns, an armed citizen could have had a chance of taking out this scum, but since this was a
"gun free zone," no one was prepared. Logically, to him, gun control helped cause this situation. Both people believe they are being "logical" and
will decry the "lack of logic" in the other person's argument.
Long time ago I took a class in symbolic logic from the department of philosophy. We did the old "If A implies B and B imples C then A implies C"
schtick using the symbolic logic character set, where "implies was a left opening "U" I can't show on this page. Some of the problems were very
very complex and, frankly, it was a lot of fun doing them.
But the one thing I remember was that depending on which way you went with your logic, you could prove "A" or you could prove "Not A" and if you
substituted statements for "A", "B", etc. you got yourself a bona fide argument. Now I can't do that today. The problems took up the entire
blackboard, but they are in Copi's "Introduction to Logic," still available, albeit expensive, if you want to check out the veracity of what I'm
saying.
So I pointed this out to the Prof, that you could prove "A" or "Not A" depending on the route and the transformations you made, and he said,
"Well, that's considered cheating." with kind of a wry grin.
What people normally mean when they say, "That person is illogical," is that "He doesn't agree with me."
Another issue is that we base our perception of "logic" on our own premis of how we suppose capital-R Reality to be. I've been doing some extensive
research into Steven Greer lately. He's considered a charlatan by most on ATS, someone who has gone off the deep end, is crazy and "illogical," But
that's really way too easy a claim. His Reality is different than yours or mine. Where we see a blinking light, at best, he sees a spaceship.
Now you may scoff and call him illogical with disdain in your voice, but if you went one on one with Greer about the issue, you'd probably lose.
Notice I'm not saying you'd be WRONG. I'm saying you would LOSE a "logical" argument because, frankly, Greer is a pretty smart guy, quick on his
feet, and quiet capable of turning you into a pretzel with his brand of "logic."
So when I hear these arguments about OTHER people being illogical, I just grin.
