Hello, I was wondering if someone could help me write a logical proof..

I am trying to express that "Belief that God exists" and Belief that God does not exist is a false dichotomy, because there is the possibility that someone can lack a belief in both propositions..

I am not sure exactly how to do this..

pic not related

>> No.2285809

are you askinf sci to argue pro religion? O_o

>> No.2285814

>>2285809
No, actually, I am trying to argue that the term Atheism does not imply a belief that God does not exist.. Only a lack of belief that God exists...

The person I am arguing with believes that non-belief in God = belief that God does not exist...

I am trying to prove logically that this is a false dichotomy.. Because the two propositions are mutually exclusive, but not jointly exhaustive..

I dont know how to express this in a logical proof..

>> No.2285818

Not knowing is the same as not believing. Because if you don't know then how can you possibly believe? You can't, therefore you don't believe in a god.

Also I suspect this is a troll thread.

Also I have a question of my own:

How is it that believing in a god is not considered a mental disorder? I mean, if I told you I believe in a santa claus then you would label me insane, but if it's a god then it's all fine and i'm not mental? Doesn't make sense...

"Atheism" means literally, "without theism". If you don't know or don't believe in a god then you are without theism.

Does it look like a religion board to you?

saged and reported, enjoy your ban.

>> No.2285837

Right.. I am an Atheist.. I am "Without Theism".. In other words, I am "without the belief in God"

That does not mean, I am "With the belief that God does not exist"..., I could not justify that claim...

So I lack a belief in God...

This is why I say "Belief that God exists" Vs "Belief that God does not exist is a false dichotomy..

Does anyone know how I could express that in a logical formula??

It's kind of like the heisenberg uncertainty principle. You are asking someone to prove an unprovable proposition. Same thing like the principle- you can never know the answer of the position of a quantum particle, because your interaction changes the outcome.

Make sense?

Something like this-

X has a value of either 0 or 1.
Both 0 and 1 are equally possible values of X.
It is impossible to determine the value of X.
Because it is impossible to determine the value of X, both 0 and 1 remain equally possible values.

Use the heisenberg uncertainty principle as a real world example of what you are trying to tell him- that there are real world examples of definitively unknowable values.

Schrodinger's Cat paradox is sort of the inverse of what you are trying to prove- that you can describe a situation where BOTH states exist simultaneously.

Easily done, they're both non zero values of belief. one is a 1 and the other -1 someone with 0 belief would have no notion a god could exist.

OP, you're going to have to stick to definitions to clarify your point. >>2285822 is right. This is the dictionary definition of atheism, and the etymology is sound. Tell your opponent that lacking a belief is simply not the same as asserting a lack of existence of something. Someone who says that god does not exist could be termed an 'anti-theist'. I believe Hitchens describes himself as one.

You may be accused of being an agnostic instead of atheist. Tell your opponent that such labels are not an either or as gnosticism and agnosticism speak to knowledge, whereas theism and atheism speak to belief.

Most atheists would be described as agnostic atheists. The term is often referred to as 'weak atheism'. It's why most simply identify as simply atheists.

I try to avoid using the word atheist when discussing my beliefs, simply because it carries with it a lot of baggage. Sam Harris said correctly that the argument that Pol Pot, Stalin and Hitler were atheists isn't going away. No matter how specious a claim it may be, no matter how weak an argument it may be. This isn't a tactic I take out of shame of my position, but out of a need to clarify and open up discussion about belief.

When someone asks me what religion I am, I simply tell them that I don't subscribe to any religious tradition. If they ask how I was raised, or what I believe I explain it to them what I believe and why. I then turn it around on them and ask them what they believe and why. Normally, by the end of the conversation I've gotten them to think about what it is they believe and why they do. Most religious people are never called upon to consider their beliefs, and it ends up being a real eye-opener for them.

OP here.. I don't believe that God exists.. But I also can't justify the belief that God does not exist..

But since I lack the belief that God exists, I consider myself an Atheist..

Because only theists believe God exists, if I am not a Theist, then I must be a nontheist (Atheist)

Anyway, is there a way to write this in a formula

(T) = Theist
(A) = Belief that God does not exist

I am trying to prove that it is possible to be (not T) and (not A) at the same time

Therefore you do believe that God does lack existence.

There are at least 3 stances on whether or not God exists...

A: "I believe God exists"
B: "I believe God does not exist"
and
C: "I do not believe God exists"


Now... it is possible that B and C are logically equivalent although I do not consider them so... but heck I might be wrong (I've been wrong in the past and I'll be wrong in the future).

Anyway let us consider a situation in which while talking with a Theist you state, "I don't believe in God" and they responded "pffft, you mean you believe God does not exit"...

They either believe that B and C are different statements, hence the need for them to put words into your mouth and attempt to make your position a belief...

OR they actually believe that B and C are logically identical... in which case why are they making an issue of the difference?


If someone asks you, "Do you believe in God/Magic/Voodoo/Unicorns?", then your response will generally be in the form "No, I don't believe in that/those"...

>> No.2286183

This isn't logic, it's semantics. And those two positions are identical. "I lack a belief in the tooth fairy," and "I believe the tooth fairy does not exist" mean the same exact thing. If you need to fine-tune your position beyond that, you need extra words, like, "But I haven't read all of the arguments FOR the tooth-fairy," or "But I'm really not that certain about the tooth-fairy one way or another."

But your original statements mean the same thing. "Weak atheism" and "Strong atheism" are useful shorthand ways of clarifying your--for lack of a better word--certainty on the subject, but it's not like they differ in kind or anything. I'm a weak atheist when it comes to deism's god (I just don't feel that the concept explains anything, and in fact only confuses the issues), and I'm a strong atheist when it comes to the wide variety of crazy-ass Muslim and Christian gods who hate gays and practically everyone else but are still all-loving.

To the question of whether or not god exists there are two possible answers: yes or no.

that coin example is saying "i dont know, i cant say onething or another".
with this in mind lets look at math.

Math is fact. Its eighter this or that.
Lets make math of your claims.

1 + 1 = 2
-1 + 1 = 0
1 + -1 = 0
-1 + -1 = -2

positive = god exists
negative = god does not exist.
0 = not positive, not negative

I am trying to show that there are more than just two options.. I managed to come up with 4:

b(G) = Belief in Gods existence
¬b(G) = Nonbelief in Gods existence
b(¬G) = Belief in Gods nonexistence
¬b(¬G) = Nonbelief in Gods nonexistence
..

I think there is a subtle difference in the wording to be honest... HOWEVER I'm willing to concede that they maybe logically equivalent BUT that does raise a question, why do people often try to force you to switch from one to the other?
T: Do you believe god exists?
A: No, I don't believe god exists.
T: HA! you mean You believe God doesn't exist!
A: ... um either they mean different things, in which case I stand by what I said or they mean the exact same thing, in which case you're actually just being a jerk...

a = b
a^2 = a*b
a^2-b^2 = a*b-b^2

Logical proofs can only operate on propositions. They don't operate on statements of belief or disbelief. You can have a proposition A: God exists or a proposition B: God does not exist. But logic doesn't deal with statements, "I believe A is wrong" or "I don't believe that A is right" (two differing statements).

You could set up some axioms maybe, like if B() is a belief function, you could specify
~(~B(A)=>B(~A))
That is, not believing in proposition A does not imply belief that proposition A is false. That is a true statement, but there's no way to prove it without defining what belief and lack of belief are.

>> No.2286445

>>2286404
From the axiom that ¬b(A) and ¬b(B) are compatible for all A and B. In other words, there are incompatible beliefs, but there are no incompatible lack of beliefs.

Sorry, I don't know how to prove it, it's just the nature of non-belief. It's sort of like a non-statement. Two non-statements can never contradict each other.

So he's saying that
¬b(G) => b(¬G)
It's fallacious because it's not supported. If you got rid of the belief function, so it was just
¬(G) => (¬G)
Then it would be true. But a lack of belief doesn't imply a belief in the opposite. Unless you were to spuriously define belief that way.

>>2287054

OP you have to define what it means to exist.

You have to show that the object "God" is beyond the category of existence.

If you can show that it is possible for God to neither exist nor not-exist, then the two positions you stated create a false dichotomy and it is possible to gave a third position and rationally suppose that God is neither an existing being nor a non-existing being. (This is not to say that he exists and doesn't exist at the same time, instead it says that such a being doesn't belong to the category of existence)

However this is extremely hard to do, existence seems to be a binary position.

Usually there are only two rational positions to hold regarding the existence of an object: either object X exists or does not.

You have to show that there is a third position, object X neither exists nor does not exist.

Good luck

>> No.2287137

>>2287108

Strictly speaking there is no false dichotomy between
those two beliefs.

Existence is binary.

If someone lacks belief in both those statements, then he holds the belief that an object (God) neither exists nor does not exist. Which violates the principle of excluded middle.

You have to show how existence is not binary and that there is a third and perhaps forth position:

A thing can exist and not exist at same time (typically contradiction)

A thing can neither exist nor not exist (typically violates excluded middle)

OP has to come up with a new foundation for what it means to exist.

>there is the possibility that someone can lack a belief in both propositions..

A false dichotomy occurs when there is a third option, that is rational.

For example, there is no third belief-option when it comes to someone's marriage status.


You believe X is a bachelor or not-a-bachelor.
The fact that you lack a belief about X's status doesn't mean those two are false dichotomies, it just means you can't form a belief.

They are only false dichotomies, if it is possible for X to be married and not-married at once, or neither married nor not-married.

Which are absurdities.

2 l B => N (belief => faith he doesn't exist)

3 l l B (auxilary assumption)

7 l B => [E & N] (conditional introduciton, 3-6)
