 Para-consistent logic is the study of logical schemas or
 systems in which the fundamental paradigms are paradoxes. It's a way of
 dealing with logical situations in which true/false can't be determined
 even axiomatically.

Most paraconsistent logics deal with paradoxes, but I know of none whose
fundamental paradigms are paradoxes. That barely makes sense to me, and is
certainly not true.

Paraconsistent logics often* allow some but not all sentences within the
logic to be both true and false. In paraconsistent logics that have simple
notions of true and false** it is usually (at least sometimes) possible to
axiomatically determine whether a sentence is true or/and false - they
wouldn't be much use if you couldn't! (not that they are much use anyway).

* Many logicians would say they all do, according to Vasiliev and Da Costa's
original definition. Some would say only some do. And some logician
somewhere will disagree with almost anything you say about paraconsistent
logics...

** Not all do, eg some have multi-value truths. Some have conditional
truths, or truths valid only in some worlds. Some have true, false, both and
neither. And so on. As usual, some logicians will disagree with this.




For those who might care, paraconsistent logics are usually defined as
non-explosive* logics. Ha! There is some argument (lots!**) about that, but
it's the generally accepted modern definition (or at least the one most
often argued about).

* logics in which ECQ does not hold. ECQ = Ex Contradictione Quodlibet,
anything follows from a contradiction. In most normal logics, if any
single sentence and it's negation can both be proved, then _every_ sentence
can be proved both true and false. This property is known as explosiveness.

** For instance, it has recently been shown that some logics traditionally
known as paraconsistent, eg Sette's atomic P1 logic, are explosive, contrary
to that definition. There are arguments about the meaning of negation as
well, all of which confuse the issue.



BTW, the name doesn't have anything to do with paradoxes, at least according
to the guy who invented it. The para bit is supposedly from an extinct
word (I forget the language, Puppy-something, really) for arising out of,
coming from. Some say it's from the Greek para- beyond; but I've never
heard the paradox story before.


I hope this at least interested some, and was not just troll-food.

 Indeed.

Hardly. What I suspect is that the effect is more related to the mental
hardiness of the subject. Their ability to step outside of their normal
perceptions and beliefs. Are they driven by fear or curiosity. The fact is
that most people (I'd say somewhere in the mid to high 90%'s) are driven
by fear. Those who can't would seem to have a much harder time of it.
I've also noted that females (no insult intended, just a non-scientific
observation) tend to last a considerably shorter time than males.

I found the experience interesting but after a few times rather boring
because the experience wasn't that different after you'd built up some
experience.

When I was 12 I was in a shop accident and lost the sight in my L. eye. As
a consequence I spent about six weeks with both eyes patched so I'm quite
familiar with SD effects. Perhaps that had something to do with it
shrug. Pretty light shows for the first couple of days, after that it
was just an annoying pain in the ass.

I also suspect that a lot of people expand upon the experience since they
expect it to be 'wild' because that's what they've been told it would be.

 Don't think I turned into an ape, but for
 about 30hrs (reconstructed) I'm not
 sure what I was.

 PS, anything less than a full cycle in a tank
 (16 hrs at least) is a bad place from whence to
 judge.

Spent way more than that in there, and more than one or two times. I
operated that tank for about six months. We finally ended up using it on
the back porch to put a couch in so it was protected from the rain.

Thanks, but no thanks. I picked minder because it
does not filter. 

minder seems to be back up now.
