Off topic.
But curious. Does something have to be factual to be true?

It depends
what you mean by true. LOL. Whole books have been written on this but
essentially there are two types of truth in philosophy...
|
|
3
|
|
|
- A necessary
truth cannot possibly be false e.g. 1+1=2. If you negate a necessary truth,
you contradict reality hence the negation is impossible.
|
|
4
|
|
|
- A
contingent truth is a true statement that could be false. So for example
“Greg read a book last weekend" is a contingent truth, because the
statement “Greg did not read a book last weekend" could have been true,
without creating a contradiction in the fabric of reality. Greg could have
chosen not to read a book, or to have read the book next weekend. Note that
additional information could turn this into a necessary truth (or necessary
falsehood) for example, if Greg has been dead for 10 years.

|
|
So to answer
your question, a necessary truth is factual. A contingent truth is a
hypothesis or theory. We may be able to verify if Greg read a book.

The
numbers one plus one is defined as equaling the number two.
|
No. The
words and symbols have their definitions, but they are not the necessary
truth. They represent it.
Key Point
Each
individual symbol has a definition like words in a language, but 1+1 is not defined
as being equal to 2. It is equal to 2 in reality.
|
11
|
|
|
In
the first of your claims regarding a so-called "necessary truth,"
you state: "A necessary truth cannot possibly be false e.g. 1+1=2. If
you negate a necessary truth, you contradict reality hence the negation is
impossible." That would imply that (1) a "necessary truth" is
actually discernible beyond all doubt and (2) that an abstraction that is
artificially defined as truth is actually meaningful and remains completely
truthful when applied to concrete situations.
|
It’s true
that experience can be used to validate the truth of 1+1=2 but one
cannot get necessity from experience. A necessary truth does not come from
experience.
Key Point
A necessary
truth exists independently of our experience.
|
12
|
|
|
For
example, in the abstract, the numbers one plus one is defined as equaling the
number two.
|
It’s not true
to say that 1+1 is defined as equalling 2 (see line 10) but the subject of
definitions raises several key points listed below
Key Point
The truth of
1+1=2 is not abstract. The ability to count from 1 to 2 (and beyond) is a
fundamental requirement for living day to day and it couldn’t be more
concrete.
The same is
true of other mathematical principles which may begin life as apparently
abstract but are later discovered to define an aspect of reality. Roger
Penrose provides an elegant explanation of numbers in the physical world in
chapter 3 of this book…
|
13
|
|
|
|
Key Point
In everyday
language, the symbols used in 1+1=2 have default meanings which are well
understood. Arguing that 1+1=2 is a fallacy by referring to different uses of
the symbols is a fallacious argument. Inventing a new language does not
negate truth.
The symbols
have definitions of course (see line 10) and different symbols can be used
(and are used) to represent the same necessary truth, just like different
languages can describe the same concept. For example, we could express 1+1=2
in binary or in Japanese or using Roman numerals…
1 + 1 = 2
1 + 1 = 102
I + I = II
いちたすいちはに一足す一波に
These
statements all say the same thing – they all refer to the same necessary
truth. A necessary truth is true in all possible worlds, and hence all
languages.
An example
where the symbols have different meanings exists in Boolean Algebra where
1+1=1. That’s because…
1 is the
symbol for TRUE
0 is the
symbol for FALSE
+ is the
symbol for OR
This does not
negate 1+1=2 because in Boolean Algebra, the symbols “1” and “0” do not
represent numerical values and the "+" symbol does not represent addition.
|
14
|
|
|
|
Key Point
1+1
essentially represents counting. In terms of a formal proof, Peano shows that
starting from zero, we can always add one to a whole number. Peano
defined axioms that accurately capture how the integers act and 1+1=2 is an
act of the integers.
|
15
|
|
|
|
Key
Point
Bertrand
Russell went even further and used formal logic to prove Peano’s axioms. It’s
not until page 362 (!) that Russell gets to the point of saying 1+1=2
The full text of the book can be found
here…

16
|
|
|
Certain
concrete examples support this interpretation and apply. If there is one coin
on a table and another coin is added, there are then two coins on the
table--or at least we perceive such to be the case through observation.
|
There are two
coins on the table even if no one observes them (see line #11)
|
17
|
|
|
A
skilled prestidigitationist can make all number of coins appear and disappear
through manipulating our perception based on observation, and through smoke and
mirrors do likewise with quite large objects--including large animals--as
well.
|
Illusionists
can create the illusion of coins (or animals) appearing and disappearing. If
an illusionist puts a coin on a table and then adds another coin and we see
three coins, we know that does not reflect reality. We know that 1+1=2 is a
necessary truth. That’s how we know what we’ve seen is an illusion. It’s not
real.
|
18
|
|
|
Note
also that when we add one and one we don't necessarily get two
|
Yes we do.
This is fallacy #1 – see line 10
|
19
|
|
|
They
could combine into a larger "one," or partially combine with
perhaps multiple fragments being left over, or one plus one could cause an
explosion with nothing left but radically transformed fragments or vapor.
|
That is a
different definition of addition.
Key Point
The
symbols “1+1” do not represent the combining of substances, chemical
reactions and physical reactions. There are different symbols for those
situations, for example:
2Na + 2H2O
→
2NaOH + H2
(see also
line 67).
|
20
|
|
|
|
Key point
The word
“addition” has two different meanings:
1 1) The action of adding something to
something else
2 2) The process of calculating the total of
two or more amounts
The necessary
truth of 1+1=2 is addition according to definition #2. Definition #1 is a
different process, for example, mixing different substances together. 1+1
does not represent the mixing of substances and any resulting chemical or
physical reactions.

A necessary
truth cannot be false e.g. 1+1=2. Why? Because if you negate a necessary
truth, you contradict reality, hence the negation is impossible. Your example
illustrates this nicely: A man puts one coin in his hand, then another coin.
He opens his hand, and there are three coins. There are two options here: The
man has contradicted reality thereby negating a necessary truth, or it's an
illusion. Turns out was an illusion using sleight of hand. In reality, he had
a hidden coin, thereby demonstrating another fact: 1+1+1=3.
|
|
22
|
|
|
Another
example from my own experience. A teacher presented a proof to the class I
was in that 1=2 (shown here) This was a shocking
moment because the teacher had contradicted reality and negated a necessary
truth. Except of course, he hadn't, because the so-called proof contained a
flaw (see if you can spot it). Turns out it's a famous puzzle but as
children, we didn't know that. The so-called proof did not reflect reality,
where 1=1, 2=2, 1+1=2 are all necessary truths.
|
True
story! It was an epiphany for me.

When
you state that "necessary truths are necessary truths" that is a
truism.
|
That
is indeed a truism – but I didn’t say it.
|
24
|
|
|
My
point again was that "necessary truths" can not necessarily be
established
in the real world.
|
They
can. This is a repeat of fallacy #2 (see line #11). A necessary truth
is true in all possible worlds. Furthermore, they are not just established by
experience, they are true even in the absence of experience
|
25
|
|
|
By
the way, you ignored my specific examples of one plus one NOT equaling two
because claiming one plus one must always equal two was itself false.
|
No
I didn’t. I explained that the third coin was an illusion. The examples
of one plus one not equalling two were based on the wrong definition of “addition”.
We know the illusionist is fooling us because nothing can negate the
necessary truth of 1+1=2.
|
26
|
|
|
Combining
one and another one of something in the real world does not necessarily
produce two of the same kind, but their combination might yield something
entirely different. Once you leave the abstract and enter the realm of
"reality," you will always face these issues.
|
This
is a repeat of fallacy #6. See line #20.

I didn't
state that "necessary truths are necessary truths" but if I had
said that, you're right, that would have been a truism. The point is that
necessary truths can be established, and 1+1=2 is perhaps the most obvious
example of a necessary truth, because if you negate that, you negate reality.
I explained this with regard to your stage magician example, and we can also
use your latest example where two things can be combined to make something
different. So let's assume we have two things: a glass of water and a spoonful
of salt. If we combine them we no longer have two things, we have one thing
(a glass of salty water). But the point is that one glass of water and one
spoonful of salt equals two things. The fact that you've combined them
afterwards is irrelevant. In order to create the salty water you needed two
things: salt and water. If you need two things, that's one thing plus another
thing.

Now
you are interpreting your abstract truism to state something slightly
different: that two things are needed to create one thing in cases where they
are combined. What if one thing plus another thing led to a chemical reaction
that resulted in any number of things--say, the detritus from an explosive
reaction that yields different bits of altered fragments? Can you still state
that one plus one still was responsible when such needed to take place in an
atmosphere where oxygen was present? I can add as many variables as you like
to demonstrate how one plus one yields a different result once it leaves the
abstract realm of pure mathematics and is applied to the "real"
world.
|
This
is a repeat of fallacies #4 and #6.

So to use
your latest example: We have one thing and another thing which when mixed
together, lead to a violent chemical reaction. So in your example we have two
things because we have one thing plus another thing. Let's assume we have a
spoonful of sodium and a beaker of water. So the question is, how many things
do we need to create that reaction? And the answer is we need two things:
Sodium and water. One thing plus another thing equals two things.
1+1=2.
|
|
30
|
|
|
If I
understand you correctly, you're trying to say that in your example, 1+1=52
because 1 spoon of sodium and 1 beaker of water can result in sodium
hydroxide, hydrogen, and 50 pieces of broken glass.
|
|
31
|
|
|
I'm wondering
if the confusion here is your not understanding what the plus sign
"+" means. It's the symbol for addition, and addition means finding
a total number of things. It does not represent the resulting quantities in a
chemical reaction.
|
|
32
|
|
|
Let's build
on the concept of 1+1=2 and see how we can count larger quantities. So for
example, if you want to bake a sponge cake you need five ingredients:
Flour
Butter
Sugar
Eggs
Baking Powder
How do we
know how many ingredients? We use addition: 1+1+1+1+1 = 5 ingredients.
But, you may
ask, how many eggs? Well, for the size of cake I have in mind, we need four
eggs. That's an egg, and another egg, and another egg and another egg. Which
is four eggs. 1+1+1+1 = 4
|
|
33
|
|
|
Before we
start cooking we put all the things we need on a table. We have a bag of
flour, a pack of butter, a bag of sugar, 4 eggs, a sachet of baking powder, a
bowl, a whisk and a cake tin. How many things are on the table? The answer is
eleven things:
|
|
34
|
|
|
|
|
35
|
|
|
|
|
36
|
|
Apologist
|
Let's
not forget how we got off on this tangent. You stated: "A necessary
truth cannot possibly be false e.g. 1+1=2. If you negate a necessary truth,
you contradict "reality" hence the negation is impossible."
|
|
37
|
|
|
What
I'm continuing to demonstrate is that such a "necessary truth" is
only an abstraction and that "reality" is another matter entirely!
|
So far, all
such demonstrations have been fallacious.
|
38
|
|
|
As
the observation that "the whole is greater than the sum of its
parts" suggests, abstractions do not necessarily retain their meaning
and quality in "real world" situations. Likewise with defining a
word in common usage per its chemical structure in its abstractly-defined
"pure" state--a state that will never be manifest in "real
world" situations. That's the point you keep missing--or ignoring!
|
?
|
39
|
|
|
Your
cake example is all artificially-defined.
|
Eh?
Artificially defined? It’s a real life example!
|
40
|
|
|
You
are likely to mis-measure and/or spill a bit of the ingredients as you
prepare the cake--and such ingredients were artificially-defined in the first
place. As long as you define what is happening in an abstract sense, you are
correct: you have A bag of flour and A bag of sugar, etc. in
your example, although all ingredients would be adulterated in a practical
sense and there is no standard measure for the volume of "an
egg"--nor would the recipe or results ever be exactly duplicated.
|
None of this
has anything to do with 1+1. So what if we “mis-measure”? The point of 1+1 is
counting. Maybe we don’t know the volume of an egg but we know how many
eggs there are. We are counting the eggs, not measuring their volume. We can
count how many ingredients we need. And there was nothing abstract
about the example.
|
41
|
|
|
My
point, as always: an abstraction does not equal a "real life"
scenario in a practical sense!
|
This is a
repeat of fallcy #7 (see line 12)
|
42
|

JimC
|
It is indeed
possible that some ingredients will be spilled or wrongly measured while
making the cake. But that doesn’t alter the fact that we needed the five
specified ingredients to make the cake. Perhaps I was a bit hasty jumping to
counting five things before resolving how to count two things. So let’s
rewind and imagine that we are going to make an omelet using these eggs:
|
|
43
|
|
|
I hope you
can see that we have an egg, and another egg. How many eggs is that? We use
he fact that 1+1=2 so, 1 egg + 1 egg = 2 eggs. We have two eggs.
But those are
contingent truths. 1+1=2 is a necessary truth. 1 egg plus 1 egg
= 1 omelette is a contingent possibility, but it's not a necessary
truth.
|
|
44
|
|
|
If you want
to challenge the concept of necessary truth, I suggest you use a different
approach, i.e. that obviously 1+1=2 because that’s how 2 is defined,
therefore it’s a truism.
|
|
45
|
|
|
Now, you may
argue that in reality, 1+1=1 because one egg and another egg makes one
omelet.
|
|
46
|
|
|
But the plus
symbol doesn't represent the process of cracking eggs into a bowl and
whisking them together. It represents addition, which means finding a total
number of things. In this case, the total number of eggs.
|
|
|
|
|
You might
argue that we could have used three eggs or one egg, you might say that no
two eggs are identical and no two omelets are identical, you might argue that
1+1=3 because we could have made three small omelets. And so on.

Apologist
|
You
are beginning with the "real world" practical sense of one plus one
yielding two of the same sort of object.
|
Doesn’t have
to be the same sort of object. See line 51.
|
48
|
|
|
I
agree with this understanding of one like "thing" plus another like
"thing" equaling two of those like "things," assuming
those like things are stable enough not to produce volatility when being
thusly combined,
|
Doesn’t have
to be a “like thing”. And it doesn’t matter if they are volatile when
combined. That is a repeat of fallacy #4 (see line 19)
|
49
|
|
|
and
further recognizing this wouldn't be strictly accurate in a fundamental
sense, where virtually everything from the eggs to the hands to the
surrounding atmosphere to whatever else is present is to be understood as energy
in motion in a vast interactive matrix.
|
We could
indeed argue that an egg, or any object, is almost entirely empty space and
consists of a swirling cloud of electrons which only give the illusion of
being solid, but that’s not the point. 1+1=2 is a necessary truth when we are
counting objects, regardless of what those objects are composed of.
|
50
|
|
JimC
|
1+1=2 is not
limited to counting the same the of object. For example, here are two
different things, a pot plant and sunglasses...
|
|
51
|
|
|
How do we
know there are two things? Because 1+1=2 (one thing and another thing gives
us two things). They don't have to be the same type of thing.
|
|
52
|
|
|
Here are two
things which, to use your words "produce volatility when being thusly
combined"…
|
|
53
|
|
|
|
|
54
|
|
|
How many
things do we need to cause volatility when thusly combined? We need two
things: A bottle of coke and a packet of mentos. We know it's two things
because 1+1=2.
|
|
55
|
|
|
Note that the
Plus sign and the Equals sign do not represent the combining of chemicals to
create an explosion. They represent addition, which means finding a total
number of things.
|
The second
definition of addition - see line 20.
|
56
|
|
|
So again note
that a necessary truth cannot be false e.g. 1+1=2. Why? Because if you negate
a necessary truth, you contradict reality, hence the negation is impossible.
Now of course, reality is complex and arguably unknowable, but the truth of
1+1=2 is part of reality. If I was to put two coins in the palm of your hand,
and you looked down and saw three coins, you'd suspect some trickery, because
you know that 1+1=2. Not 3.

The
"result" is one "thing" and another "thing"
being combined--both of which are basically inert in relation to each
other--hence two separate "things" are the result of this
combination. The transition from abstract "truth" to
"reality" applies in this case.
|
It doesn’t
matter whether they are inert or not. 1+1=2 does not represent the mixing
together of different substances, inert or otherwise.
|
58
|
|
|
Your
second example is false. The "equal" sign does not apply in this
example.
|
The equals
sign applies when we are counting. There are two objects: A packet of mentos
and a bottle of coke. One object + another object = 2 objects. The “+” sign
does not represent inserting the mentos into the coke bottle. The equals sign
represents equality.
|
59
|
|
|
One
thing and another thing are combined, but unlike your previous example, we do
not then get "two" things but something "other"--in this
case, a likely foam--so this is best translated as one plus one equals
"something else."
|
This is a
repeat of fallacy #6 (see line 20) and also note that 1+1=(something else) is
a terminology that is never used, because it’s not true.

Your
statement that 1+1 represents two things being "combined"
demonstrates your misunderstanding. 1+1=2 represents addition in order
to find a total number of things. So Coke is one thing and Mentos are another
thing. How many things do you need to create a Coke geyser? You need two
things. How do we know it's two things? Because 1+1=2. But that doesn't describe
what you refer to as "volatility when being thusly combined".
|
|
62
|
|
|
Perhaps it
will help if we use notation to describe the chemical and physical reactions
you have in mind. We've seen that 1+1=2 does not represent a physical
reaction so below is a symbolic representation that does represent "volatility
when being thusly combined"…
|
|
62
|
|
|
|
1+1=(something)
does not represent this situation and is never used to represent it.
|
63
|
|
|
That picture
represents a contingent truth rather than a necessary truth.
|
|
64
|
|
|
Now let's
look at how to represent a chemical reaction. You may remember the explosive
reaction between sodium and water from your schooldays and I hope you agree
that is a good example of what you call "volatility when being thusly
combined". To cause that reaction we need two chemicals: Sodium and
water. That's one thing plus another thing, which is two things because
1+1=2.
|
|
65
|
|
|
However we've
seen that 1+1=2 does not represent any kind of physical or chemical
combination or reaction. We can represent the sodium and water chemical
reaction in words...
sodium and
water produces sodium hydroxide and hydrogen
|
|
66
|
|
|
...and
symbolically...
|
|
67
|
|
|
2Na + 2H2O
→
2NaOH + H2

Note the use
of “→”
instead of “=”

|
All of this
science stuff is fun but it has nothing to do with God or religion so let's
use a theological example - the concept of the Trinity. Christianity teaches
that God consists of three persons: The Father, The Son and the Holy Spirit.
Is that two persons? No because 1+1=2. It's three persons because 1+1+1=3. So
if anyone asks you how many persons comprise the Trinity, you can confidently
say "three" because you know it's one person and another and
another.
|
|
70
|
|
|
However...
this concept is akin to your "volatility when being thusly combined"
concept because Christianity teaches that those three persons are distinct
from one another in terms of their origin and relationship, but they are one
in all else, co-equal, co-eternal and consubstantial, and each is God, whole
and entire. So we see the fact of 1+1+1=3 doesn't help to describe that
concept beyond counting the number of persons.
|
The concept
of the Trinity can only be described in words or pictures. 1+1+1=3 does not
describe that concept.
|
71
|
|
|
Just like the
physical and chemical reactions described above, we need a different
symbolism, and here it is…

No,
Jim. "1+1" represents addition of one thing and another, of
course--but even that is only half of this very basic equation. It's the
"=2" where the issue is, since that isn't necessarily the result of
adding one thing and another thing.
|
This is a repeat
of fallacy #6 (see line 20)
|
74
|
|
|
We
start with two things--but that doesn't necessarily mean that two things are
the result of their being added together. Don't forget the "equals"
part of the equation!
|
This is a
repeat of fallacy #6 (see line 20)
The “equals
part of the equation” is what represents equality. I will have to try and
explain how equations are balanced.
I’m
reminded of the quote by Sam Harris: “If someone doesn’t value
logic, what logical argument could you provide to show the importance of
logic?”
|
75
|
|
|
A
necessary truth must remain true in ALL situations--and we have already seen
that it doesn't.
|
A necessary
truth does indeed remain true in all situations – and we have seen that it
does. This is fallacy #8.
|
76
|
|
|
The
reaction equation is a fascinating matter to discuss indeed but irrelevant to
the point at hand.
|
It’s
completely relevant. It represents the situation that the Apologist has
described. He has simply ignored a point that demolishes his argument.
|
77
|
|
|
If
you refer to "1+1=2" as a NECESSARY truth, it is only a NECESSARY
truth in the ABSTRACT--by DEFINITION! Even then I could refer to other ways
of using such symbols--for example in binary, 1+1 would equal 10--and in
advanced mathematics even in referencing a decimal base there are exceptions
as well.
|
This is a
repeat of fallacy #3 (see line 13).
Also note
that if using binary, this would be written 1 + 1 = 102
In order to
indicate the result is binary. The default assumption is decimal.
|
78
|
|
|
|
|
79
|
|
|
The
only reason for taking this matter to such a ridiculous extreme was to
indicate a more basic truth: what a "necessary truth" is in the
abstract--by symbolic definition--is not a necessary truth in
"reality."
|
This is a
repeat of fallacy #7 (see line 12)
|
80
|
|
|
What
is "absolute" proof in the abstract--by symbolic definition--does
not lead to conclusions that prove anything infallibly in concrete reality.
|
Nothing could
be more concrete than the necessary truth of 1+1=2.
|
81
|
|
|
So
again, the best we can hope for are reasoned conclusions based on reasonable faith
that our perceptions and evidence that we reference are accurate. It is
impossible to get beyond that faith basis when concluding ANYTHING when
referencing "reality."
|
The necessary
truth of 1+1=2 does not require faith. It doesn’t even require people!
|
82
|
|
|
Regarding
the Holy Trinity - Agreed--and in this case you reference three entities
which, in combination, are partially distinct and partially part of a common
whole. This is an instance that can be symbolized 1+1+1=3, or again could be
symbolized as 1+1+1=1. This would not apply to all combinations of 1+1+1.
|
It can’t be
symbolised as 1+1+1=1 because that is not true. The equals sign
represents equality so if 1+1+1=2 then that could be rearranged to show that
1+1=1-1 which is nonsense.
The Concept
of the Trinity can be symbolised graphically or in words, but not
arithmetically, because it is not an example of values being counted.

I think I see
where your confusion is – it’s with the word “addition”. The word has two
meanings and you are equivocating them (in the same way you equivocate
different meanings of the word "faith" and so on). You are right to
say, for example, that two chemicals can be added together to make a new
compound. That’s the first definition of “addition”
• • The action or process of adding
something to something else.
But addition
has another meaning:
• • The process of calculating the total
of two or more numbers or amounts.
|
I should have
made this clearer before now. See line 20.
|
84
|
|
|
1+1=2
represents the second definition. Mathematical notation doesn't make sense
with regard to the first definition. That's why for the examples you provide,
we need to use pictures...
|
|
85
|
|
|
|
|
86
|
|
|
...or
words...
sodium +
water →
sodium hydroxide + hydrogen
|
|
87
|
|
|
...or
different symbols...
2Na + 2H2O
→
2NaOH + H2
|
Key Point
When
describing physical reactions, the equals sign “=” is not used because this
is not the calculation of a total number of things. The arrow represents a
process whereby different substances are produced by the reaction.
|
88
|
|
|
...but what
we can't do is use 1+1=2 because that equation does not represent adding
substances together, it represents the calculation of a total.
|
|
89
|
|
|
You also seem
confused about the meaning of the equals sign. The "=" symbol is
used in an equation to represent equality. In other words, (1+1) and (2) are
equal to each other. The equation remains valid when reversed...
2=1+1
…because the
expression “2” and the expression “1+1” have the same value.
|
Key Point
The symbol
“=” represents equality, and is a fulcrum upon which an equation is balanced,
like a set of scales. This means 1+1=2 can be rearranged as long as the
balance is maintained, for example:
1=2-1
…and this represents
another necessary truth - If someone has two things and one is taken away,
they have one thing left. But if two substances are mixed together, it
doesn’t follow that the reaction is reversible. See also fallacy #4.
|
90
|
|
|
So to
reiterate: 1+1=2 does not represent the action or process of adding something
to something else, e.g. adding Mentos to Diet Coke, or sodium to water, or
flour with milk and eggs, and so on. It represents a total.
|
|
91
|
|
|
Coincidentally,
I’ve been babysitting my youngest grandchild all day (she’s 10 months old),
and she has learned to stack plastic cups (and knock them down). Her cousins
who are 9 and 6 joined us after school and I mentioned a funny man in America
who thinks 1+1=1. The nine year old suggested I send you a pic of what his
baby cousin was up to, so here it is…
|
This is all
true by the way. I’m not making this up.
|
92
|
|
|
|
|
93
|
|
|
His question
to you is this: How many cups can you see stacked on the book? (The answer is
two by the way). Supplementary question: How many cups in the picture? (I
will let you work that one out yourself but as a clue, they are each a
different colour: one green, one pink and one yellow).
|
|
94
|
|
|
And again
from a philosophical angle – note the difference between the necessary
truth of 1+1=2 and the contingent truth of flour, eggs and milk
making a pancake.
|
|
95
|
|
|
You are of
course correct to point out that 1+1=10 in binary. I made an assumption that
in everyday language, human beings use base 10. So for future reference, note
that whenever I refer to numbers, I am using base 10 unless stated otherwise.
That's why there are three divine persons in the trinity, not 11
(binary).

I
think the original point The Apologist was making has been lost; that
bringing concepts into a concrete world, or the "real" world,
sometimes does not translate completely (see lines 10 to 16)
|
Sometimes,
yes.
|
97
|
|
|
So,
if you were to ask me "hey, what does 1 quart of milk plus 1 quart of
water equal?" I would pipe up fairly quickly: 2 quarts. I'm using your
definition of addition: (The process of calculating the total of two or
more numbers or amounts.) and They represents addition, which means
finding a total number of things. As you illustrated with your picture of
a plant and sunglasses, they don’t necessarily have to be the same items.
|
If we are
looking at two vessels, one containing water and one containing milk, then
yes we have two containers, each containing a quart of liquid. We can count
the containers. 1+1=2
Perhaps it’s
natural to assume that if we then pour a quart of water into a large bucket
followed by a quart of milk we will have 2 quarts of liquid in the bucket,
but it’s not necessarily true. A quart is a unit of volume, and volumes vary
according to many factors, such as density and temperature. Or maybe there’s
a subtle chemical reaction between water and milk that changes the density. I
don’t know. The point is that 1+1 does not represent pouring liquid into a
bucket. It represents counting. See line 14.
|
98
|
|
|
Yet
there is this:
(Please
see 1. Examples that illustrate the difference between a priori and a
posteriori (empirical) justification)
|
The
Stanford Encyclopedia of Philosophy – my favourite resource for
philosophy! The link contains many helpful examples…
|
99
|
|
|
a.
2 + 2 = 4.
b.
2 quarts of any liquid added to 2 more quarts of any liquid = 4 quarts of
liquid
(9b)
is false, for if you add two quarts of carbon tetrachloride to two quarts of
water you will get less than four quarts of liquid because the molecules pack
together in a way that diminishes the total volume. Still, someone not
knowing of such examples might be justified in believing (9b).
|
This is a
more extreme example of the milk and water mixture which illustrates the
point that 1+1=2 does not represent the mixture of substances.
The
Stanford Encyclopedia of Philosophy makes the point that 2+2=4 is true but it
doesn’t represent a situation where chemicals are mixed together. See lines
14 and 19.
|
100
|
|
|
So,
the "funny man in America who thinks 1+1=1" came up with examples
that are valid in my opinion.
|
They are not
valid examples for the reasons explained in the encyclopaedia…
“The
first member of the pair is supposed to be an example in which, if we are
justified in believing the proposition, we are a priori justified in
believing it, and the second member an example in which, if we are justified
in believing the proposition, we are a posteriori (that is, empirically)
justified in believing it.”
2+2=4
is a necessary truth hence it is justified a priori. But the result of mixing
two liquids together cannot be justified a priori – it can only be confirmed
empirically.
We
are also seeing fallacy #9 here (see line 87) because the equation is not
balanced. If 1+1=1 then rearranging gives 1=0 which we know is not
true. So 1 + 1 ≠ 1
|
101
|
|
|
That's
coming from a "funny woman in America" who only viewed the
totality: 1 quart + 1 quart = 2 quarts.
|
It depends
how the funny woman is using the plus symbol “+”. Is she counting or is she
mixing liquids together? If she’s counting, the answer is 2 quarts. If she’s
mixing, the total volume might be 2 quarts but not necessarily.

As I said,
the word "addition" has two different meanings.
|
See line 20
|
104
|
|
|
The
arithmetical notation of "plus" and "equals" signs does
not describe the combining of substances and chemical or physical redactions.
It describes numerical values. So if you add two quarts of carbon
tetrachloride to two quarts of water you may well get less than four quarts
of liquid because of a chemical reaction. There is a special notation for
that kind of process which uses an arrow instead of equals sign, or you can
describe the process in words (as you have).
|
Also see line
67
|
105
|
|
|
But you can't
describe the mixing of two substances using the arithmetical notation 2+2=4
because that describes values. If you want to do the carbon tetrachloride
experiment you describe, you will need to acquire 2 quarts of each liquid
which is 4 quarts. That's a fact because 2+2=4. If you subsequently mix them
together, you can't describe that process with arithmetic notation. The
notation 2+2=4 is not applicable to chemical or physical reactions.

I
agree the word "addition" has two different meanings.
|
Yay!
|
107
|
|
|
Chemical
notation is a horse of a different color. And the equation stays in balance.
If you start with 2H you end with 2H even after the chemical reaction.
|
Yes it is
indeed a different type of horse– because it describes a different situation.
It applies to the other meaning of “addition” – it doesn’t apply to the
meaning used in 1+1=2. And yes chemical reaction equations are balanced – but
that doesn’t make chemical reactions a necessary truth. They are a contingent
truth.
|
108
|
|
|
But
one of your points was this the different meanings of addition (see lines 83
and 84). Doesn't change my opinion that the examples were valid in
translating from the abstract to the concrete.
|
This is a
repeat of fallacy #6. The examples didn’t demonstrate a translation from
abstract to concrete. They falsely compared two different phenomena. See line
20
|
109
|
|
|
So
if you see 1+1=2, you need to consider in the concrete world what you are
doing…
|
EXACTLY. If
you see 1+1=2 you are counting from 1 to 2 in the concrete world.
|

|
|
…
or combining things: 2H + O --> H20
|
NO! Notice
the absence of the equals sign. The student of philosophy was absolutely
right to use the arrow symbol which represents a net forward reaction.
A chemical reaction is never represented as 1+1=2 because it’s not counting
values and it’s not necessarily true. The water equation (when balanced)
looks like this…
2H2
+ O2 → 2H2O
…but this is
not a necessary truth because hydrogen and water don’t always combine to form
water. That equation represents what happens when they do. But that’s very
different to 1+1=2 which is a necessary truth.
|
112
|
|
|
I
could be wrong, but I don't think the majority of people seeing 1+1=2 think
to themselves: "Wait - that's mathematical notation, so I need to
calculate the total, not add one thing to another thing".
|
I agree.
People know intuitively what 1+1=2 means when they see it. They know
it’s true, and they intuitively know that 1+1=1 is not true. No one ever
uses the symbols “1+1” to describe the combining of substances. Also,
the link on line 98 explains this in terms of a priori and a posteriori

If you refer
to the link you provided, you will see what I mean:
9a. 2 + 2 = 4.
9b
2 quarts of any liquid added to 2 more quarts of any liquid = 4 quarts of
liquid.
9a is a true
proposition 9b is a false proposition.
https://plato.stanford.edu/entries/apriori/
Similarly for
the other examples in that article.
|
|
114
|
|
|
In the
concrete world, 1+1=2 represents a total number of things, it does not
represent the combining or mixing of things. 1+1=2 does not represent pouring
a quart of one liquid into a container with a quart of another liquid.
I think the
majority of people understand what 1+1=2 means. Perhaps not everyone realises
what happens if you combine chemicals, but nevertheless, 1+1=2 is not a
notation that is used when combining chemicals.

|
In
referring back to the link I provided, I think it is important to include the
information that follows after 9b was determined to be a false proposition.
I've cited the site, as you have, so I won't again, but the article also says:
(9b)
is false, for if you add two quarts of carbon tetrachloride to two quarts of
water you will get less than four quarts of liquid because the molecules pack
together in a way that diminishes the total volume. Still, someone not
knowing of such examples might be justified in believing (9b). And in the second paragraph:
Just as we can be empirically justified in believing a false proposition
(e.g., 9b), we can also be a priori justified in believing a false
proposition.
|
That is the
point. 9(b) is false even if some people believe that it’s true. We can
refer back to the water and milk example on line 97. It’s natural to assume
that a quart of water and a quart of milk makes two quarts of liquid, but it
might not be true. It’s not a necessary truth. 1+1=2 is a necessary truth but
doesn’t represent the mixing of substances. It’s how we count values.
1+1=2 is a
necessary truth because it is independent of our experience.
|
116
|
|
|
I
agree that 1+1=2 is not a notation that is used when combining chemicals. I
think it's pertinent that the article did not say the proposition was false
because you cannot pour one liquid into another; rather, that the total
volume was diminished because of the way the molecules pack in the
combination of the two.
|
The
proposition was false because when you pour one liquid into another, we cause
a chemical or physical reaction. We have to measure the outcome. We are not
counting values. Hence that situation is not represented by 1+1.
|
117
|
|
|
I
also think it's important the words "empirically justified" were
used in the second paragraph. So I think you are saying is that you can place
a coin on the table, and then another coin on the table, to equal two coins.
You then can place a quart of milk on the table, and a quart of water on the
table, and you have two quarts. (using the 2nd definition you provided,
mathematical notation).
|
Correct. But
the 2nd definition doesn’t refer to mathematical notation. It’s a
definition of addition in the sense of counting values. Mathematical notation
is just language to express that truth.
|
118
|
|
|
Then,
if you want to determine the total volume of the two quarts, you combine them
(determining value by the first definition of addition you provided, and
excluding items that are either physically or chemically reactive). Is this
right?
|
That sounds
over complicated. If you want to estimate the value of the total volume when
two substances are mixed together, and you are not an expert in chemistry,
you can add the two volumes together, but you won’t know for sure what the
actual resulting volume is unless you measure the volume of the mixture after
the mixture has been created. One doesn’t need to be an expert I anything to
know that 1+1=2.

The result of
any situation where substances are added together does not qualify as a
necessary truth. It is a contingent truth at best, for the reason explained
(a priori) in the article you linked to.
"A
priori justification is a type of epistemic justification that is, in some
sense, independent of experience."
With regard
to the example you give, if you place a quart of milk on the table, and a
quart of water on the table, you have two quarts of liquid on the table
because 1+1=2. We can count the items but even if we couldn't, it's a
necessary truth that if you have a bottle of something and a bottle of
something else then you have two bottles.
If you
combine the water and milk into a single container, it is tempting to believe
we have two quarts of liquid and you could reasonably predict that it will
consist of two quarts. But whatever you believe or predict, whatever your
justification, it's not necessarily true. The only way to be sure of the
volume of the milk/water mixture is to measure it. 1+1=2 is a necessary truth
but a quart of milk added to a quart of water might not have a volume of two
quarts. It's an a posteriori situation. As the article says, we can be
empirically justified in believing a false proposition. But, the only way to
verify that proposition is to measure it empirically.
Note the
symbols you used previously for your hydrogen and oxygen reaction. You didn't
use an equals sign, you used an arrow -> and you were absolutely right to
do so. That arrow represents produces rather than equals because
an equation representing the mixing of substances does not represent equality
in the way 1+1=2 does.

If
you place a quart of milk on the table, and a quart of water on the table,
you have two quarts of liquid on the table because the abstract happens to
translate well into the concrete in this example.
|
1+1=2
translates perfectly when we are counting values, which is what it represents
and which is what is happening in this example.
|
121
|
|
|
But
remember what you just said above: "The result of any situation where
substances are added together does not qualify as a necessary
truth."
|
That’s
correct. Adding substances together is not the same as counting values. Once
you’ve counted your ingredients, you could mix them up in all sorts of ways.
The necessary truth of 1+1=2 applies when you count them. See line 20.
|
122
|
|
|
It's
the "=" that is at issue here, and that "=" symbol
appears in the equation you proffered as a "necessary" truth.
|
The ‘=” sign
is not the issue. This is a repeat of fallacy #9 (see line 89). The symbol
“=” represent equality and the equation is balanced like a set of scales,
around the “=”. That’s why the following are all necessary truths:
1+1=2
2=1+1
1=2-1
They are all
balanced rearrangements of the same equation. That’s what the “=” allows us
to do.
|
123
|
|
|
You
say 1+1=2 but it is '10' in the case of , or 'II' in the case of Roman numerals, and
that's just while we're in the process of interpreting your given abstract
offering of "1+1=2" and claiming that it is a "necessary"
truth!
|
This is a
repeat of fallacy #3. “2”, “10”, “two” and “II” are just some ways of
representing “2”. There are many others. But they all represent the same
thing. If we write 1+1=2 in Japanese or Arabic characters, it’s still a
necessary truth because it’s true in all possible worlds which means it’s true
in all possible languages. See line 13
|
124
|
|
|
We
can count
bottles if bottles are the subject because they are (presumably) inert
relative to each other and remain distinct entities when combined, with the
result being two distinct entities. we've already noted that combining two
volatile substances "equals" something else entirely!
|
This is a
repeat of fallacy #4 (see line 19)
|
125
|
|
|
You
asked us to take at face value--without elaboration or explanation or
qualification or even defining the symbols themselves--that "1+1=2"
is a NECESSARY truth!
|
That’s true.
I took it for granted that the symbols I used for 1+1=2 would be well understood
(and it seemed to be by the person I addressed it to). It didn’t occur
to me that someone would consider “1+1” as an appropriate way to describe
combining substances.
|
126
|
|
|
Need
I state it one more time? The point--the fundamental point--the ONLY relevant
point in discussion here at this point--is that "absolute" and
"necessary" truths only exist in the abstract! Sometimes those
abstractions translate well and are relevant to real life circumstances--
sometimes they do not and are not.
|
This is a repeat
of fallacy #7 (see line 12)
|
127
|
|
|
So--once
again--referring to "necessary truths" that exist only in the realm
of the abstract will never allow us to bridge the gap in our own
interpretations of "reality" without our relying on a necessary
faith component in the process. That is also true of "scientific"
experiments on supposedly falsifiable matters and whatever "verification"
processes are offered as evidence for conclusions drawn from such. Any claim
that "faith" can be ruled out by following such processes only
reflects the illusions of those proffering such assertions!
|
This is a
repeat of fallacy #7 (see line 12)
The comments
regarding faith don’t seem relevant at all!

The equals
sign represents equality. The equation 1+1=2 represents the necessary truth.
Note that "10" in binary and "II" in Roman numerals are
all equivalent to "2" in base 10. They are all different symbols
for the same necessary truth. It doesn't matter what language we use:
"uno mas uno es igual a dos" is just as true as "one plus one
equals two". 1+1=2 is a necessary truth even if there were no symbols,
even if human beings never existed. It is "true in all possible
worlds."
|
|
129
|
|
|
I think
you've become further confused about the symbols thing because you've
responded to what I've said without reading what a
student of philosophy provided. To clarify, when A student of philosophy referred to a chemical
reaction, she (rightly) used the arrow symbol rather than equals. That is the
convention in chemistry. Here's a clue. I previously showed what happens when
sodium is put in water and here is the chemical equation:
|
|
130
|
|
|
2Na + 2H2O → 2NaOH + H2
|
|
131
|
|
|
The arrow
means "produces" or "yields". An equals sign is
inappropriate when describing chemical or physical reactions. Can you guess
why?
|
|
132

If you're
still unsure about the concept, I would refer you to the link A student of philosophy provided which explains a

I
note that you are now adding multiple qualifiers to your original
statement--"1+1=2" as a "necessary" truth--and continue
to ignore the matter of combining one thing and another thing does not
necessarily result in two "things" at all when those two things are
not distinct and/or are volatile in combination, nor when this formula does
not even necessarily apply in higher mathematics.
|
This is a
repeat of fallacy #4 - see line 19
|
134
|
|
|
All
of this is not to say that abstractions aren't useful or that
"1+1=2" is a generally sound and meaningful understanding of
mathematics applied to "real" life in many--if not most-- practical
circumstances.
|
This is a
repeat of fallacy #7 – see line 12. Interestingly, the Apologist seems to
have his own rules on when it’s appropriate to apply 1+1=2. I wonder how he
determines when it’s appropriate and when it’s not?
|
135
|
|
|
This
all brings us back to the original point: when attempting to apply abstract "absolutes"
to "real life" circumstances/scenarios, things get murky.
"Necessary" truths lose their necessity unless qualified to such an
extent that they become meaningless.
|
This is a
repeat of fallacy #7 – see line 12. Things only get murky when they are not
applied properly. The necessary truth of 1+1=2 is perfectly clear to anyone
who has learned how to count – that’s one of the most basic skills that we
are taught even before we attend school. Far from being meaningless, it
is fundamentally meaningful.
|
136
|
|
|
The
biggest revelation of failure when one relies on abstract constructs and
principles, of course, eventually leads to the collapse of
"scientific" abstractions--including the "laws" of
physics and chemistry--to account for the creation of our universe per its
principles, and for that matter for life, consciousness, and independent
thought and creativity itself.

This is
irrelevant. The laws of physics and chemistry are not necessary truths.

As I said,
1+1=2 is a necessary truth even if there were no symbols, even if human
beings never existed. It is "true in all possible worlds." Your so
called "real life examples" are not examples of 1+1=2 which is why
they are irrelevant. If the necessary truth of 1+1=2 didn't apply in real
life (which is what you seem to be suggesting) then reality would be very
different.
A question
for you: If 1+1=2 was not a necessary truth, would our universe even be able
to exist?
I've been
looking for some online resources which will help explain the concept, and I think this is good: but
please note it goes much further than 1+1=2 (it progresses to 2+2=4 and 4+4=8
for example). It also alludes to subtraction. So for example, the necessary
truth of 1+1=2 can be rearranged to illustrate another necessary truth: 2-1=1
so for example, if you have two things, and I take one away, you will be left
with one thing.
Note that
your reference to the laws of physics and chemistry is a completely different
topic. The laws of nature are not necessary truths. The laws of nature are
defined by human beings and they have been revised and created many times and
continue to be. From a philosophical angle, they are contingent truths,
not necessary truths because the laws of nature may not be true in all
possible worlds. However, some philosophers disagree. For example, there's an
argument from Intelligent Design that says certain forces (such as the strong
force and the electromagnetic force) are a necessary truth because they are
"fine tuned" to a precise value and therefore God designed the
universe. Creationists therefore deny the existence of other universes (or
regions in our universe) where those values can be different.

Oh the number
one is not my favourite number
Cos one means
only me and there’s no you.
But just add
one more you’ll see
That makes
two that’s you and me!
Adding makes
things fun when one and one are two.
Adding,
adding, adding
Such a nifty
thing to do
It’s such fun
to add when one and one make two.
Oh the number
two is not my favourite number
Though two is
fine, I’d love to add some more.
So let’s add
another two
That’s the
perfect thing to do
Adding makes
things fun when two and two are four.
Adding,
adding, adding
It’s a thing
that I adore
It’s such fun
to add when two and two make four.
The number
four is not my favourite number
C’mon let’s
add some more I just can’t wait.
Cos right now
we have four
I say why not
add four more?
Adding makes
things fun when four and four are eight.
Adding,
adding, adding
Boy oh boy is
adding great
It’s such fun
to add when four and four make eight.
Now four and
four are eight
And that’s
really kinda great.
Eight and one
is nine
And that’s
one more friend of mine.
Now if we add
one more
You know what
happens then?
Nine and one
makes ten of us and so let’s sing again
Adding,
adding adding
Boy oh boy is
adding fun
But now our
little adding song is done
Yes now our
little adding song is done
We’ve added
up together song is done.
See how great
adding is Bert?

"1+1=2"
is an arrangement of visible linear shapes requiring interpretation.
Interpreting "1+1=2" as "one plus one equals two" gives
those shapes limited meaning in the abstract.
|
This is a
repeat of fallacy #7 – see line 12.
Not limited
meaning. Fundamental meaning.
|
139
|
|
|
Applying
that abstraction to real life circumstances requires further clarification as
to when how and why that applies. Real life circumstances consist of endless
variables and myriads of approaches to interpreting such. Applying an
abstraction to all of those circumstances, variables and approaches requires
further and further elaboration and noting of exceptions to the abstract
principle. "Necessary truth"--which brooks no exceptions--gets lost
in the process.
|
Hopefully I
have provided that clarification, but I must admit it’s rare to meet an adult
who needs the concept of 1+1=2 to be clarified.
|
|
|
|
The
universe is able to exist whether or not "1+1=2" applies in all
circumstances. The universe needn't explain or account for its existence
through your assertion on the matter, Jim--rather the other way around!
|
If the result
of 1+1 was variable, there would be no universe. Even if there was, the
Apologist wouldn’t know how old he was, what day it was, what time it was, or
how many children he had. We wouldn’t be having this conversation because
there’d be no computers. 1+1=2 is true in all possible worlds.
|
140
|
|
|
No
Sesame Street or pre-school concept applies to my reasoned response, Jim--
but I completely understand how your mind set is locked that way!
|
Sesame Street
and pre-school concepts are what the Apologist has failed to grasp.
They are vital concepts – that’s why they are taught in
pre-school.
|
141
|
|
|
Necessary
truths brook no exception, Jim--if what we learn from contingent truths
demonstrate otherwise, then necessary truths aren't necessary truths!
|
It’s true
that a necessary truth brooks no exception. Contingent truths are not
necessary truths (there are several types of truth). But contingent are not
exceptions to necessary truths. They represent a different situation.
|
142
|
|
|
Who
in the world is presenting an argument from the perspective of intelligent
design here? Are you again proffering unsupported insinuations and
suggestions and pretending that they have a rational basis?
|
The Apologist
introduced the laws of physics on line 136. Given the context of
necessary truth and contingent truth, it seemed reasonable to me to examine
those laws in that context and to consider if anyone considers the laws of
physics to be necessary truth. The only example of that I can think of is
intelligent design and the concept of fine tuning.

Your
introduction of the nature of language and symbols takes us in a different
direction, but let's run with it. The necessary truth of 1+1=2 doesn't lie
any "visible linear shapes" as you put it, be they numeric,
English, Japanese, Spanish, Braille or whatever. It was always a necessary
truth even before human beings existed, and it always will be. "True in
all possible worlds".
Bonus
question for you: What's the best way to illustrate 1+1=2 if not using
symbols and text? Clue: How would teach 1+1=2 to a two year old child?
What human
beings have been able to do, beginning (I think) with Isaac Newton, is
to provide formal proofs that 1+1=2.
But again
note: the necessary truth of 1+1=2 does not come from human beings. Let me
give you a religious analogy.
From a
theistic point of view:
a) The
reality of God doesn't come from words or symbols on a page.
b) The
reality of God is independent of how any such statement is written or
expressed
c) Any
attempt to express the reality of God using any kind of written text or
symbols is bound to fall short of describing the true nature of God
Do you
disagree with any of those points?
You shouldn't
dismiss what you call "pre-school concepts" because that's where we
have to learn necessary truths such as 1+1=2. The importance of what we learn
before we are 5 years old cannot be overstated. So much else is built on that
and follows on from that. Imagine how your life would be if you could not
count (and neither could your calculator or computer). Your life would be
impossible.
|
|
144
|
|
|
And again
regarding your point on laws of nature - note the difference between a
necessary truth such as 1+1=2 and the laws of nature. The laws of nature are not
necessary truths. They are defined by human beings and they have been
revised and created many times and continue to be. They are contingent
truths.
I think by
far the best resource provided on this topic here came from A Student of Philosophy and so I provide it again...
|
|
145
|
|
|
On the other
hand, some philosophers disagree that the laws of nature are contingent
truth, and argue that they are necessary truths. For example, philosophers
who advocate Intelligent Design argue that certain forces are a necessary
truth because they are "fine tuned" to a precise value - the
universe wouldn't exist if they were not true and therefore God designed the
universe.

You
didn't begin by stating that "one plus one equals two" is a
necessary truth--you began by stating "1+1=2" is a necessary truth.
That's the first error, because it relies on our assumption that we interpret
"1+1=2" as "one plus one equals two." A trivial matter in
and of itself, but part of my overall point that anything proffered as a
"fundamental truth" needs to be deconstructed and examined from the
start to see how--or if--it translates from the abstract to
"reality" without further qualifications and definitions becoming
necessary.
|
The first
part of this paragraph is a repeat of fallacy #3 – see line 13. The second
part is a repeat of fallacy #7 (see line 12)
|
|
|
|
1+1=2
is not true in all possible worlds, Jim, because I've demonstrated otherwise.
Adding one thing to another thing does not necessarily give you two
"things." Adding one thing to another thing might yield an entirely
different result. I've made this point over and over, and you are ignoring
it.
|
This is a
repeat of fallacy #8 – see line 75.
|
|
|
|
With
regard to teaching 1+1=2 to a two year old child, one could just use language
without using symbols or writing systems at all--one need not even be literate
to understand the concept--or for that matter one could silently place one
inert thing next to another inert thing, and repeat as often and with as many
"things" as necessary to impart the idea.
|
Language is
not a great idea (just look at the confusion in the preceding posts) but
silently placing things next to other things is much better. For example,
wooden blocks are a great way to teach the necessary truth of 1+1=2 to
infants. I think I remember being taught that way. They can see a thing and a
thing. It can also demonstrate subtraction. However, I have used that
approach here by means of graphical images, and it hasn’t worked.
|
|
|
|
That
might lead to a more fundamental grasp on "reality" than relying on
symbols and abstractions because doing so--your case being a good
example--might lead one to invest more "absolute certainty" in the
symbols themselves and what they stand for in a practical sense than is
really justifiable.
|
I have never
claimed “absolute certainty in the symbols themselves” – this is a repeat of
fallacy #3
|
147
|
|
|
It
is a useful fundamental concept with myriads of applications--but it
isn't an "absolute truth" in all circumstances.
|
This is a
repeat of fallacy #8 (see line 75)
|
148
|
|
|
Your
conclusion on intelligent design and fine tuning is a non sequitur, as you
very well know--not that it is the wrong conclusion, but that it requires
further explanation.
|
If something
requires further explanation, that doesn’t make it a non sequitur. I’d
be happy to provide further explanation if it’s needed.
|
149
|
|
|
Because
you know this, you falsely state the issue as well because that isn't the
only reasoning involved and that is not the way those who advocate
intelligent design arrive at their conclusion. therefore, false
representation followed by false reasoning is a straw man
|
Falsely
state? I stated a fact - philosophers who advocate Intelligent Design argue
that certain forces are a necessary truth because they are "fine
tuned" to a precise value - the universe wouldn't exist if they were not
true and therefore God designed the universe. Those philosophers are taking
the “all possible worlds” one step further and saying there is only one
possible world. (And it’s obviously not a straw man).

It’s true
that I began by stating that 1+1=2 is a necessary truth. I made the
assumption that you would know what those symbols meant but you are
absolutely correct to say that any proposition must be clearly defined. I was
hoping that had now been done, but I see you continue to choose the wrong
meaning of the word “addition”. The word has two meanings as I said before,
and your examples of chemical and physical reactions are not examples of 1+1
so they are irrelevant.
|
|
151
|
|
|
You gave the
wrong answer to the bonus question. The best way to illustrate 1+1=2 to a two
year old child is definitely not to use language. That’s probably the
worst method (and if you look at this discussion you can see why!) The best
way to demonstrate any necessary truth is by means of reality. For example,
we can use small wooden blocks. Without using words or symbols one can
experience that block and block is block block. And if you have block block,
taking away a block leaves block. We can of course represent that
symbolically as;
|
|
|
|
|
1+1=2
2-1=1
|
|
152
|
|
|
... or we can
describe it in words etc. but the important thing is that the symbols and
words are not the necessary truth, they are simply a way of representing it.
The necessary truth exists in the absence of words, symbols and indeed, human
beings, because it is true in all possible worlds, and it would indeed be
possible to have a world that does not include human beings.
|
|
153
|
|
|
Regarding
your point that the “laws of physics and chemistry cannot account for the
creation of our universe, life, consciousness”, etc. - you have to bear in
mind that those laws are not necessary truths. They are contingent truths.
Or are they? Some philosophers argue that they are necessary truths. For
example, philosophers who advocate Intelligent Design argue that certain
forces are a necessary truth because they are "fine tuned" to a
precise value - the universe wouldn't exist if they were not true and
therefore God designed the universe. I think your point is that there’s no
such thing as a necessary truth, in which case I assume you disagree with the
argument that the laws of nature are necessary truths (as I do).

My
examples of chemical and physical reactions are not irrelevant at all, Jim. "One
plus one" is also in need of elaboration and clarification. If
"one" chemical component is added to "one" other chemical
component, the result is not necessarily a "two" as I have amply
demonstrated.
|
This is a
repeat of fallacy #4 – see line 19
|
155
|
|
|
You
now object and claim that there is a separate "meaning" of the word
where your necessary truth still applies, even though it obviously doesn't
apply in the "other" meaning for which I provided an example.
|
I made it
clear there were different meanings some time ago – see line 83. Of
course the necessary truth of 1+1 doesn’t apply to the other meaning.
That’s the point.
|
156
|
|
|
All
this leads to a more fundamental point: when we attempt to apply absolutist
abstractions to "reality" they don't necessarily apply in the way
in which they were presented, and actually the more variables that exist in
"reality" the more and more qualifications, explanations and
exceptions to the rule must be added to the original abstraction in order for
it to retain any meaning or relevance.
|
This is a
repeat of fallacy #7
|
157
|
|
|
All
this leads to the most fundamental point: statements which are self-defined
by our terminology as "necessary" truths tend to lose their
"necessariniss" the more complex the situation one applies such in
matters of "reality." "Necessary" in its abstract
definition in human language--not necessarily "necessary" as
understood in those terms when applied to "reality."
|
This is a
repeat of fallacy #8
|
158
|
|
|
My
way of teaching 1+1=2 to children is superior because the child does not have
to learn theoretical definitions that come with a claim that they
"necessarily" apply to "reality"--s/he can merely witness
"reality" and draw conclusions of how to conceptualize and describe
such on their own, in a much more relevant and open minded manner.
|
My suggestion
of using wooden blocks or pictures does not require theoretical definitions.
The necessary truth of 1+1=2 can be observed. Although I do wonder if we are
both advocating the same method here i.e. to avoid any kind of language.
Perhaps we are at cross-purposes? I will provide some exercises which
may help to clarify.

I thought I
had explained that "one plus one" does not represent adding
chemical components together. That is a different meaning of the word
"add". If you are struggling to understand the necessary truth of
1+1=2 then think of counting and imagine what would happen to reality
counting from 1 to 2 wasn't a necessary truth. Learning to count is different
to learning about chemical or physical reactions and you have to master the
former before you can master the latter. The examples you are providing are contingent
truths not necessary truths. For more detail, refer to the
explanation of chemical and physical reactions earlier in the thread. Also I
implore you to read the material A Student of
Philosophy provided.
|
|
160
|
|
|
Your
suggestion to use language to teach children how to count is definitely not
superior - it couldn't be worse! That's because of the ambiguity of language
which you yourself have highlighted the problems of. Your approach is further
compounded by your logorrhoea which would baffle any child and most adults!
So the best way to illustrate 1+1=2 (or any necessary truth) to a two year
old child is by means of demonstrating reality itself without resorting to
language at all. For example, we can use small wooden blocks. Without using
words or symbols one can experience that block and block is block block. One
can feel them if one is blind, one can see them if one is deaf. And
furthermore, it is easy to demonstrate that if you have block block, taking
away a block leaves block. So another necessary truth emerges which is 2-1=1
which I hope you can see is simply a rearrangement of 1+1=2. We can of course
represent all of that symbolically and verbally as well, but that can come
later.
|
|

Have a go at
these exercises (just Set A for now) and see how you get on. I can provide the solutions.

Regarding
your point that the “laws of physics and chemistry cannot account for the
creation of our universe, life, consciousness”, etc. - I'm not sure why
you raised that point in this thread, but anyway, you have to bear in mind
that those laws are not necessary truths. They are contingent
truths. They may not be true in all possible worlds. But is it that
simple? Some philosophers argue that they are necessary truths. For example,
philosophers who advocate Intelligent Design argue that certain forces are a
necessary truth because they are "fine tuned" to a precise value -
the universe wouldn't exist if they were not true and therefore God designed
the universe. I think your point is that there’s no such thing as a necessary
truth (correct me if I'm wrong). If that is your argument, it would be
interesting to see how you would challenge the creationist argument.

Stop
right there, Jim. You made the posit that "1+1=2 is a NECESSARY
truth." Period! No explanations--no further
"clarifications"--just a "necessary" truth, in and of
itself! In the abstract that would be generally correct, although I could
also demonstrate that there are exceptions to 1+1=2 even in the abstract
structure of mathematics itself.
|
This is a
repeat of fallacy #3 and fallacy #8.
|
164
|
|
|
Yet
a single exception demolishes your "necessary" truth, and that has
been more than provided. So back to the basic point: absolutes and
"necessary" matters (where they actually exist) as defined in the
abstract do not necessarily translate well when applied to
"reality." Got it?
|
A single
exception would negate the concept of necessary truth, but the apologist has
not provided a single exception. All his examples are fallacious,
specifically fallacies #4 #6 and #8
|
165
|
|
|
What
part of silently demonstrating the result of combining one object with
another would you define as "logorrhoea" Jim?
|
Silently
demonstrating would be a good thing, and that was my point all along.
Hence my use of graphics during the course of this conversation. But
using language… nope.
|
166
|
|
|
I
didn't say that there are no necessary truths, Jim--just that they may
generally be beyond our grasp.
|
I wonder if
he can give an example of a necessary truth?
|
167
|
|
|
"Necessary"
truths for someone like you--who thinks in terms of rigid categorizations--
may have trouble grasping that concept, as already demonstrated in your
assertion of "1+1=2" being a "necessary" truth in and of
itself. Basically, you believe that the human constructs that have been
devised within the limits of human language and understanding and bound by
the limitations of the human condition have meaning and applicability beyond
those constraints.
|
This is a
repeat of fallacy #3
|
168
|
|
|
As
for "creationists" arguing--in your view--on behalf of "fine
tuning," I see those arguments as hoisting those who believe in
Scientism on their own petard. They are using the arguments of scientific
naturalists and their subscription to the philosophical assumptions of
logical positivism to demonstrate how the universe could not have come about
per their assumptions. Also, whether you admit it or not (which you won't),
your assertion that god's existence is "unlikely" ultimately rests
on those same deconstructed and discredited assumptions--and that is what
makes your desperate ploys to avoid admitting such to be such a fascinating
thing to witness!
|
None of this
addresses the point regarding necessary truth of the laws of physics
according to Creationism and Fine Tuning.

It's true
that I assumed that the necessary truth of 1+1=2 didn’t need an explanation,
but I hope you agree I have subsequently provided you with an explanation and
many, many examples. Also note
the examples
and source material provided by A Student of
Philosohy and the differences between a priori, a posteriori,
necessary truth, contingent truth, the analytic and the synthetic and so
on.
|
|
170
|
|
|
I wonder if
you're now confusing demonstrating with proof. Note that demonstrating 1+1=2
using two objects is very different to proving 1+1=2. Let me know if
you want to see the formal proof but in the meantime note another basic
philosophical principle: We cannot get necessity from experience. 1+1=2 is a
necessary truth because it is independent of any experience. It is a necessary
truth even if there is no life existing to experience it. Hence it is true in
all possible worlds.
|
|
171
|
|
|
Later in your
post you seem to suggest that you agree there is such a thing as necessary truth.
If you don't accept 1+1=2 is a necessary truth, then can you give an example
of what you do consider to be a necessary truth? As a prompt, here are two
more necessary truths. Tell me what you think...
a) 17 is a
prime number.
b) If Greg is a bachelor, he is unmarried.

When
you refer to the examples and source material provided by A Student of

parroting a matter that has been deconstructed and responded to multiple
times. If you have nothing to offer in response to such, I accept your tacit
concession to my perspective on such matters.

Here's
more food for thought on the matter:
https://www.quora.com/When-does-one-plus-one-not-equal-two-1
|
This is
pretty good and illustrates what I’ve said with regard to the use of symbols
on lines 31, 49, 128 etc. Symbols are of no use if they are not defined. So
for the necessary truth of 1+1=2 we have to define what "1" means,
what "+" means what "2" means and what "="
means. And that's exactly what Russell’s formal proof does (see line 15).
|
174
|
|
|
It’s
true that 17 is a prime number in the abstract, by definition.
|
This is a
variation of fallacy #1. The number 17 is not a prime number by definition;
it is a prime number because it fits the definition of a prime number.
|
175
|
|
|
Note
that it is consistent with the definition of a prime number.
|
Yes! That’s
more like it.
|
176
|
|
|
"1+1=2"
is not a definition, but a formula.
|
1+1=2
is not a formula, it is an equation. This is because of the equals sign and
because there are no variables. A formula has more than one variable –
it is more like a recipe. For example, Coca Cola have a secret formula.
If we stick to mathematical examples…
x
= 2y - 1 is a formula (two variables, x and )
a2
+ b2 = c2 is a formula (three variables, a, b and c)
x2
– 16 = 0 is an equation
And
again note the point on line #89 – the equals sign is like a pivot about
which the equation balances. 1+1=2 therefore 1=2-1. And so on.
|
177
|
|
|
1+1=2
is a claim that one added to one equals two
|
It’s not a
claim. It’s a necessary truth.
|
|
|
|
As
for the statement “If Greg is a bachelor, he is unmarried” - Same point as above.

The link you've
provided illustrates my point: language and symbols are of no use if they are
not defined. So for the necessary truth of 1+1=2 we have to define what
"1" means, what "+" means what "2" means and
what "=" means. And that's exactly what the formal proof does (in
fact most of the formal proof consists of those definitions). As I said
before, if you want to see the formal proof, let me know. But the important
point here is that the necessary truth of 1+1=2 is a necessary truth
regardless of the language or symbols. Those are just a means of expressing a
necessary truth.
I didn't
quite follow your final point - are you saying "17 is prime" is a
necessary truth?

don't have to take this conversation in the direction of having to explain to

for error, such as when attempting to divide by zero.
|
So far, the
exceptions haven’t been exceptions. They’ve been examples of a different
situation rather than 1+1. This is fallacy #8 again.
The reference
to divide by zero harks back to another misunderstanding of mathematics the
Apologist revealed a few years ago, where he claimed divide by zero was “a
built in glitch” in mathematics!
This time he
thinks divide by zero is a structural weakness. LOL

significantly, we know of exceptions in the "real" world. Adding
one "thing" to another "thing" quite often can result in
something other than two discreet "things."
|
This is a repeat
of fallacy #4. See line 19.
|
184
|
|
|
You
are lost in abstract theories and fail to note when they don't translate well
to concrete "reality."
|
1+1=2
translates perfectly well into concrete reality. Life would be impossible if
it didn’t.
|
185
|
|
|
The
definition of a prime number is quite straightforward: it is a number not
divisible by any other whole number other than one or itself.
|
Close.
To be strictly accurate, a prime number is a natural
number greater than 1 that has no positive divisors
other than 1 and itself.
|
186
|
|
|
It
is a definition that only exists in the abstract, however, relevant only to
the artificial construct of mathematics itself.
|
That’s not
true. Prime numbers are extremely relevant in real life.
|
187
|
|
|
It
is not a formula which makes a claim--such as "one thing plus another
thing equals two things."
|
A prime
number isn’t a formula, it’s a number. But there are formulas which generate
prime numbers, such as…
where n+1 is
prime if and only if n!mod(n+1)=n.
Note that
“one thing plus another thing equals two things is not a formula – it’s an
equation.”

The
number "1" would fit that definition but it is not regarded as a
prime number

True. The
definition provided by the Apologist wasn’t the full definition.

Yes,
it's all about the way abstract concepts happen to be defined for abstract
purposes--again a matter that may or may not translate well into "real
life" situations and purposes.
|
That’s his
way of saying he got the definition wrong. LOL

I was hoping
you were now up to speed with the definitions of "1" "+"
"2" and "=" but your comment that "adding one
thing to another thing quite often can result in something other than two
discreet things" suggests that you don't. Your comment about
dividing by zero illustrates a deeper issue with your understanding of
mathematics, which is disappointing because I've addressed that before,
albeit a couple of years ago. Here's a reminder
|
|
191
|
|
|
Your comments
regarding prime number suggests you don't appreciate how mathematics models
reality. Imagine you had 17 things and you wanted to distribute them equally
to people, yet keep the things whole. What are your options? If you don't
know what I mean imagine you had 8 things and you wanted to distribute them
equally. Your options would be to give them all to one person, or one thing
to 8 people, or 2 things to 4 people, or 4 things to 2 people. So... if you
had 17 things your options are...? For bonus points, can you think of other
practical applications of prime numbers?
|
Should I mention
the application of prime numbers in cryptography? Nah.
|
192
|
|
|
As a
footnote, I again plead with you to refer to the source material provided
originally regarding the nature of truth.

Your
reference to definitions is just you parroting a matter that has already
been deconstructed and responded to. If you have nothing further to offer, I
accept your tacit concession to my perspective on the matter.
|
LOL
|
194
|
|
|
As
for the practical applications of prime numbers, same point as above. I never
claimed that mathematics has no useful applications, much less that it isn't
reliable in a vast number of such--under specific circumstances.
|
The point
being avoided here is the Apologist’s false assertion that necessary truth
only exists as an abstract concept, not in reality. This is fallacy #7.
|
195
|
|
|
The
issue, again, has to do with FUNDAMENTAL TRUTH(S)--which brook NO
EXCEPTIONS!
|
It’s not an
issue. A necessary truth is true in all possible worlds.
|
196
|
|
|
The
next point following that observation is that "fundamental"
truths--as defined in the abstract--can quickly get "messy" when
applied to real-life situations, requiring further and further nuanced
explanations to apply to the situation at hand for whatever purpose is
relevant to its application.
|
It became
messy when the Apologist introduced “real life situations” that were not
examples of 1+1. And it became messier as he tried to justify his false
analogy. This is a repeat of fallacy #4.
|
197
|
|
|
That's
it, and as far as I can see it's the only relevance to the subject at hand
for religious discussion purposes. If you believe that what you are stating
above regarding mathematics is relevant in any other way to purposes under
discussion here, then clarify that matter and we'll take it from there.
|
The Apologist
seems to have forgotten that he started this entire conversation when he
jumped in after I answered a question for someone else (see lines 1 to 9). I
have tried to introduce a religious angle (see lines 69-72, 137, 143, 145,
153, 162, etc.) but the Apologist wasn’t interested.
|
198
|
|
|
I
won’t refer to the source material provided originally regarding the nature
of truth without your clarification of the points you are claiming are
relevant to the subject at hand, Jim. State such clearly, along with what
your reasoning on the matter, and we can take the discussion from there.
|

If you read
the thread from the top you can see things only get messy when you misapply
the concepts so that they don't reflect real life situations or when you use
the wrong definitions.
|
|

|
|
|
But on a
wider point - are you saying there's no such thing as a necessary truth?
Again - look at the philosophy sources provided by A
Student of Philosophy and myself towards the start of the
thread.

Rather
the opposite, Jim--I'm the one providing "real life" examples and
noting how your abstract concepts don't necessarily apply--remember?
|
This is a
repeat of fallacy #8 (see line 75)
|
202
|
|
|
Of
course "necessary truths" exist--they're just difficult to
translate from abstractions to real life situations. Even the way we
conceptualize them may be faulty, given that they are supposed to have
applicability beyond our human limitations of language and reasoning.
|
Excellent. I
will ask him for an example of a necessary truth. That will help.

Hold
it right there, Jim,--you can't see the forest for the trees! Remember how
this all started?
|
Yep! See line
1.
|
207
|
|
|
I
refer you back yet again to your original quote:
"A
necessary truth cannot possibly be false e.g. 1+1=2. If you negate a
necessary truth, you contradict reality hence the negation is impossible."
|
Correct.
|
208
|
|
|
Now
I gave you the benefit of the doubt in rendering "1+1=2" as
"one plus one equals two," except where I pointed out the binary
equation, where 1+1=10. Note that I also mentioned instances in higher math
where this equation is also not a "necessary truth" even in a
decimal system--happy to elaborate--but that would be irrelevant to the
point.
|
Actually,
when using binary, it would be written 1 + 1 = 102
The default
number system which people use in day to day conversation, is decimal, so the
subscript ”2” would be used to denote binary is being used. Perhaps the
apologist thinks 10 in binary is “ten” but 10 in binary is actually 2. Or to
use the correct notation, 2 = 102
In any case
this is a repeat of fallacy #3 (see line 13)
|
209
|
|
|
The
point is that you made an assertion which you claimed was a NECESSARY TRUTH.
A NECESSARY truth would not brook a single exception.
|
Correct
|
210
|
|
|
In
admitting two definitions to "addition" you have already demolished
the basis of your assertion!
|
The fact that
the Apologist bases his examples on the wrong definition demolishes his
argument. See fallacy #4 on line 19
|
211
|
|
|
So
once again, the basic point: "NECESSARY" truths expressed in
precisely defined abstract terms don't necessarily translate from the
abstract to "reality." Got it?
|
This is a
repeat of fallacy #7 – see line 12

Your reference
to binary is confusing. 10 is the binary representation of two so 1+1=2 in
decimal is equivalent to 1+1=10 in binary. They are both saying one plus one
equals two. You're not suggesting that 10 in binary represents ten are you?
Regardless of what symbols or language we use, 1+1=2 remains a necessary
truth. (It's true in "every possible world" as the philosophers
say). We could for example, use the Roman system where: I + I = II (that's
not eleven by the way).

|
But
that's not the way you put it. You wrote "1+1=2," and tried to pass
it off as a "necessary truth" and you are still doing so!
|
I didn’t try
to pass it off as a necessary truth. It is a necessary truth (see line
8)
|
214
|
|
|
I
provided the interpretation "one plus one equals two," remember? A
small difference, but one which yet again demonstrates how translation from
abstract to concrete can go awry--even on the symbolic level.
|
That’s not an
interpretation. That’s the same thing. There’s no difference. This is
a repeat of fallacy #3 (see line 13)

If you prefer
to state 1+1=2 in English: "one plus one equals two" - that's fine
with me.
