Bob is tall.
Bob is a man.
therefore
All men are tall.
True or False?
Bob is a man.
All men are tall.
therefore
Bob is tall.
True or false?
First false, second true.
Splendid. Second question:
How did you "know" the first one was false?
What if were are a Maasai warrior named Bob and never left the village?
Actually, nature has made things such that you can't
know what's true,period, with or without logic.

Both are false, because the premises are false.
Bob is actually a woman genetically. And she's
only tall relative to runty short guys.
Exactly - it is a false premise to suppose that all men are tall and
as you say tallness is subjective.
No inclusivity function in the first two statements, but there is in the
last which is supposed to be derived from the previous two.

The categories for "tallness" and "man" are arbitrarily defined
elsewhere. Maybe you prefer this re-statement
B = T
B = M
Therefore M = T for all M
Sure. Though the word, "truth," in the title
might lead you to expect that we're talking
about all truth. But consider the following
paradox:
If this statement is true, then there is no god.
Clearly the above statement is true, since
the condition does imply the consequent.
The consequent is in fact irrelevant to its
truth, therefore any arbitrary statement is true.
Everthing is true, according to logic, even
the statement, "nothing is true."
Assumed knowledge/accepted wisdom has been a problem with many IQ
tests.

The term "inclusivity function" is new to me, but I think you mean what some
people call a universal quantifier - "for all" as in "All ravens are black".
But then it is not true that universally-quantified sentences have to be
derived from other universally-quantified sentences
e.g. "Bob is tall" implies "All non-tall people are non-Bobs" (provided
"Bob" is understood to refer to a unique person)
you may be both completely logical and completely insane

Dodgy notation. "=" normally denotes a symmetric relation, which is not the
case here. Bob is an example of a tall person, but a tall person is not an
example of Bob. You are better off with set-theoretic (or indeed logical)

Silly wabbit. That's too easy.
Now, why do you think logic (and there are many forms of logic) is
truth? Logic cannot inform us of nature or reality.

... dreary
All animals are colored plaid
Bob is an animal
Therefore Bob is the color of plaid
Better:
"You Can't Know What's True Until You Understand Logic" because "that's
just the way nature "made" things".
Can logic apply here?
So, Nature made some things things that can never know what is true
because it is possible to both never understand logic and/or be made by
nature without even this potential. Rocks, for instance, can never know
what is true since they can not understand logic, or so they keep
insisting.
Yet it's true rocks exist. Rocks are part of what's true even if they are
incapable of knowing, of understanding and of certain forms of logic. Can
a 'you' who does not understand logic then know a rock as being just not
what's true? Or are all rocks just beyond the scope of all understanding
of this most unfortunate, void of logic 'you' who can not know what's
true?
AKA "Philosophical Masturbation"
Which goes to show your ignorance of logic
1) Those statements ONLY apply to the problem posed
They are NOT necessarily statements about anything else.
2) In problem 2), the predicate (and NOT a "supposition" as you claim),
that "All men are tall" is NOT a premise
It's a statement made SOLELY for the logical problem given.
Whether it is true or false in the real world has NOTHING to do with
the logical problem posed
SNAP!!!! You're fucking awesome!
Reminds me of that joke about economists...,
Two economists are stranded on a desert island with only a tin of
beans.
One says to the other “let’s suppose we have a tin opener”
Wouldn’t that be a joke about philosophers, and economists are shown
to use logic and reason?
If we supposed we had a tin-opener, then we could open the tin,
therefore... let us build a tin-opener. (resolved)
I will add the tile, it's 3 falsehoods.
Ah, so how exactly would you render this notation on Usenet? Felt pen, or

>Sorry but, that's just the way nature "made" things.
Logic is inherent in itself.
People who need to render mathematical notation in ascii usually find ways
of doing so. I'm not at all sure that any form of notation really gives an
advantage here, because the natural language is both precise and concise.
But if you're going to introduce a symbolic notation, it doesn't make sense
to use one that's less precise than the natural languange, IMHO.

Explain to me why the 3 are false, please.
It changes nothing to the fact that the second is false because of

end in the uncomfortable situation of having to consider that both

And by the way "All men are tall" *IS* a premise in the second

Sorry, but the post in question was a test of Formal Logic and Formal
Logic need not address the natural world. It is contained in itself. A
common criticism of Formal Logic is that it cannot inform us of nature.
It need not, either.
Consider that a free education from 'a prof'.
> No stupid,
Speaking of stupid, ewe are dropping context, the topic still existing
between ewe and me is the one ewe ran away from.
YOUR claim was, that with your beliefs you dont bother to check
whether or not they correspond to reality.
YOU stated your "belief" was that your mind was a part and product of
your body (has a material basis) you then claimed another belief of
yours is, that the mind has no material basis.
I pointed out the blatant contradiction, to which you then said, that,
just because ewe have beliefs that doesn't mean ewe have checked them
against reality.
At that point ewe ran away.

I disagree. They are fruads.
Ironic that even though it was clearly stated, it was ignored
But it happens on lot on tests as well
One defines strict parameters, and there will always be some who will ignore
them and then come back later to whine that it's "not fair" to be failed
because they ignored the rules.

And yet for all that time, humans have have plenty of innate unreason
and illogic.
Your claim is incorrect and obviously so. The lack of reason has been
demonstrated in only the most recent of that long history. Let's start
from when centralized decision makers began to serve themselves rather
than the people they were supposed to represent. That's not to say
there wasn't conflict during those 200,000 years, there most certainly
was. But we have never before witnessed fraud on such a grand scale,
which serves so few at the expense of so many. The many, are going to
put an end to it eventually either by agreement or by force.
Let's begin by addressing why the GDP equation rewards vice. What say
you?
I don't want to split hair, you respect definitions, period.
Formal logic can inform us about nature, it just that it is not
considered as a complete mean of justification or its aim, with
reason.
Formal logic don't contain the condemnation of the application of
reason on false premises ? Serious ?
Do you understand and accept that if you were using Meldon's original
post in an examination, and tryied to evaluate the answers in all
fairness, you will have a problem ? Why motivate "what that cretin
want me to answer, I'm supposed to be tested on logic and the idiot
shot himself in the foot ?" in the mind of your students ? That's a
situation you really should avoid if you want the respect necessary
for your condition.
Messing with questions should be your nightmare as a teacher.
I don't want to harass you, I respect your function and I know it can
be difficult but a teacher of logic is not supposed to behave like an
"artist".
The warnings and exceptions about logic are part of the matter, you
are a vandal if you don't take the whole together.
You are the splitter and consequently, destroyer.
You separate what should not be separated and then condemn the parts
like an idiot. What is your reason for doing so ?
Who cares if an idiot calls me a vandal
You see, I can do the name-calling thing as well
The fact that seems to confuse you is that in the stated syllogisms, there
is no need for the predicates to be true, real, or in any way related to
nature
In actual fact, in a syllogism, the two predicates can be COMPLETELY FALSE
when compared in nature
For example:
The Moon is green
All green objects are cheese
The Moon is cheese.
Neither of the predicates are true in "real life"
But as a logical syllogism, it does not matter that the predicates are not
true in real life.
Their only purpose is to set up the logical conclusion in THIS and ONLY THIS
exercise
Now you're responding to yourself too ?
An idiot conversing with an idiot..
Who would have thought it ....
More name-calling from a loser
You see, I can do this too...
They are categorical arguments that turn out, after being examined
using the
methods developed by Aristotle, to be unsound.
Thank goodness Aristotle wasn't around 200,000 years ago. LMAO
And apparently, you are either unable to identify a complement for
clarification or are completly dishonest.
What's so funny?
Unable to make a distinction between name-calling and accurate
description of reality ?

That changes nothing because the actual question is "true or false ?"
You could have a case if the question was "Does the conclusion is
logically valid in the context of the premises ?"
If I say that I'm master in applied science, will it ease things ?
It would certainly offer a possible explaination for your motives. LMAO

That would be the first moment that centralized decision making began.
In fact for most of history, it never crossed the minds of centralized
decision makers that that they were even supposed to be "representing"
those they ruled. Even when they had some kind of representative
government all they were representing was a small minority of the
populace. The "right people". The rest were rabble at best, and
outright property at worst. Not that this was in fact illogical.
After all logic is entirely dependant on the premises you put into it.
And lacking mass communication or even widespread literacy, the degree
to which a civilizations could be representative of its constituents
was limited.
Wow! From the first chiefs right through to Babylon, the central power
served itself exclusively and ignored the well being of the people and
still survived without being killed? (yeesh) I don't deny some
corruption along the way, but to assume central power didn't give a
shit about the people is completely contrary to every example I've
ever seen in the animal world including our own species. That reminds
me of Greenspan claiming the problem is “human nature” implying of
course, that we are inherently greedy while 100,000 years of trade
indicates we were inherently fair. How bizarre! One must question a
person's motives for propogating such a myth.
The welfare of the people was important to the extent that it served
the monarch's power. But of course the important thing was to keep the
alliegiance of the warrior class. Inured to suffering and aware of
the futility of rebellion, most of the time peasants and slaves
remained compliiant.

There are many forms of logic. Formal logic is the most simple. Its
rules are not concerned with the veracity of the premises (as they
relate to the world).
Zeda is a menchza.
All menchzas are katable.
Zeda is katable.
Logic cannot inform us of nature. We bring premises into a true/false
structure, and therein begins the fundamental problem.
It might be immoral or just plain stupid to make false premises, and
that's the matter at hand. Formal logic cannot help that case.
Ok, but I still consider there is a potential pedagological problem
with the questions asked. I discussed it with a pedagogue yesterday,
it seems to me that she agreed with me that the historical/
pedagological separation of the matter into submatter should not lead
to the punishement of accuracy.

I have a problem with the transformation of a limit into an
impossibility. Maybe we don't put the same weight on "inform" or I
would prefer more subtility with that kind of claim. I would evaluate
it as false too.
Should I read that as "Formal Logic cannot inform us of nature." ?
Currently I hold that "Logic, alone is unsufficient to lead to a
complet understanding of nature".

The problem, it's that it is not a true/false structure and I don't
understand why it should be evaluated in such a way when it can be
solved easily by changing the questions ?

The matter at hand, from my point of view, is an other art, education.
I'm more interested in discussing "teaching formal logic" than "formal
logic", am I more or less understandable (english is not my mother
tongue) ?
The matter at hand, from my point of view, is what seems to be a
tradition that maybe need to be changed.

I was attempting to show how fundamental logic is to human
understanding. I should have known that sort of thing would not sit
well with the “authorities”. Lol
