More Glitches
Here is a Sorites Failure: (in honor of Lewis Carroll)
Curly believes: that babies are logical;
that illogical people
are despised;
and that despised
people cannot manage a crocodile;
and babies can manage
a crocodile, being logical and respected.
Larry believes: that babies are illogical;
that illogical people
are not despised;
and that despised
people cannot manage a crocodile;
and babies can manage
a crocodile, being illogically respected.
Moe believes: that babies are illogical;
that illogical people
are despised;
and that despised
people can manage a crocodile;
and babies can manage
a crocodile, being despised.
Majorities agree: (L&M) Babies are illogical;
(M&K) Illogical people are despised;
(K&L) Despised people cannot manage a crocodile;
yet they all
agree that babies can manage a crocodile!
The sorites failure implies this heap
glitch:
Curly says: 100 grains of sand
are the smallest heap.
Larry says: 101 grains are the
smallest heap.
Moe says: 102 grains are the smallest heap.
Majorities believe:
* 100 grains of sand are not a
heap.
* 101 grains are a heap.
* 101 grains are not the smallest
heap.
Here is a Set Loop:
Moe Larry Curly
Apes {Dr.0} {Dr.0, #1} {}
Bozos {Dr.0, #1} {} {Dr.0}
Crooks {} {Dr.0} {Dr.0, #1}
Majorities agree that:
* All apes are bozos.
* All bozos are
crooks.
* All crooks are
apes.
Yet not the reverse! That is:
* Not all bozos are
apes.
* Not all crooks are
bozos.
* Not all apes are
crooks.
And worst of all, every
Stooge agrees:
** These three
classes form a BARBARA syllogism:
all X are Y; all Y
are Z; therefore all X are Z.
So the Stooges, those bunglers,
made a huge mess of BARBARA, in the very act of affirming it! These spinning
set loops make mincemeat of classical logic. How barbaric!
Here is a Double Bind:
Moe Larry Curly
Can we choose chocolate? yes no no
Can we choose vanilla? no no yes
Do we have to choose? yes no yes
Majorities
believe:
* We can’t choose chocolate.
* We can’t choose vanilla.
* We have to choose.
The Stooges are in a collective double-bind,
even though no one of them is!
Here is an Orlov Doubt State:
Moe Larry Curly
Can we tell chocolate from
vanilla? yes no no
Can we choose at random? no no yes
Do we have to choose? yes no yes
Majorities
believe:
* We can’t tell chocolate from
vanilla.
* We can’t choose at random.
* We have to choose.
The collective is in a quandary,
even though no individual Stooge is.
In
this Failed Reductio troika,
reductio ad absurdum fails:
Moe: Alice did not fall down a
rabbit hole
Larry: Alice fell down a rabbit
hole, and I am not a monkey’s uncle.
Curly: Alice fell down a rabbit
hole, and I am a monkey’s uncle.
So by 2/3 majorities each:
MK:
If Alice fell down a rabbit hole, then I am a monkey’s uncle.
LM:
If Alice fell down a rabbit hole, then I am not a monkey’s uncle.
KL:
Alice fell down a rabbit hole.
In
general the Failed Reductio troika looks like:
Moe: not A
Larry:
A and not B
Curly:
A and B
So by 2/3 majorities each:
MK:
If A then B
LM:
If A then not B
KL:
A
Here
is its dual; the “Failed Dilemma”;
Moe: B
Larry:
not B and A
Curly:
not B and not A
So by 2/3 majorities each:
MK:
A implies B
LM:
not A implies B
KL:
not B
For
instance, this “Permission Troika”:
Moe: Everything is permitted.
Larry:
Not everything is permitted, and God does not exist.
Curly:
Not everything is permitted, and God does exist.
So by 2/3 majorities each:
MK:
If there is no God, then everything is permitted.
LM:
If there is a God, then everything is permitted.
KL:
Not everything is permitted.
