If you do not have the positive belief that something (X) exists then, by definition, you lack that positive belief that X exists. Where X is God, this is sufficient for some to use the label "atheist".
Ok. What does it mean to have “positive belief” in God, as opposed to a basic belief in God?
You have basically said that if one does not belief that God exists, it is sufficient to use the label “atheist”.
Correct because one cannot believe in a thing, concept, or ideaology if they are unknown to them. In the same breath said person cannot argue for or against something that is unknown to them. Unless of course they are fools.
Some might require one to have at least thought about X, even if only to conclude that they are not otherwise aware of it, or find a definition meaningless etc. This is to distinguish, for example, someone who has concluded that they lack belief in X, from someone who has yet to give it any thought.
Just because one does not give God any thought does not mean that person has no knowledge or understanding of God.
Concluding that one is atheist or theist does not make one an atheist or theist. The designation is already there whether you decide or not. One can however decide to move away from the designation over time. It’s not different to getting over breaking up with someone you love, and having to move on. Or when someone close to you dies. Eventually you will get over it and move on.
So, no, you don't necessarily need a known and understood definition to lack belief that the thing exists. You don't know what a Gliptz is, so you can not say that you have a positive belief that a Gliptz exists, can you. True, you also can not say that a Glipitz does not exist. But an atheist, at least as commonly understood here, only requires the former, not the latter.
This is why we don’t start threads, or have debates about Gliptz. We have no idea of what one is so believing or not in the Gliptz, or believing or not that it exists is never expressed.
OTOH God has been expressed throughout history right up to the present. Because we have some knowledge and understanding of God. We couldn’t be atheist, agnostic, or theist, if we didn’t.
What is it about God that makes one an atheist?
If one does not accept evidences for God (google evidence for God), what reasons can you give for this non acceptance?
Agnosticism is a different position, about what is known, or the knowability, of the subject matter.
What is it about the subject matter that make an agnostic believe that God as ultimate reality cannot be known?
What do they know about God (in the first place) to make that decision?
If you don't have a meaningful definition of something then that in itself is sufficient for some to consider themselves necessarily agnostic on the matter.
What do you mean by (meaningful definition)?
Does an agnostic have any idea at all about God, or even the claims made about God?
They couldn't go so far as to say that Glipitz are an unknowable phenomenon precisely because they, personally, don't know what is meant by the term.
Are you saying an agnostic does not know what is meant by the term “God”?
But in so far as they deem themselves to lack any knowledge of Glipitz, even as far as a meaningful definition, is surely sufficient to say "I don't know...".
But they don’t leave it there.
They will still argue about God.
If one has no idea of something, what are they arguing about?
Sure, but until you decide that they do exist, you necessarily lack belief that they do, right?
I would neither believe or lack a belief.
How could I?
What would it be based on?
To me "God" is a meaningless concept, akin to asking what happened before time began.
Why is it?
I therefore lack belief that God exists - i.e. an atheist (as I have at least considered the position) - and I also can not say what evidence would convince me.
So what is God to you, as opposed to what is NOT God.
I think the whole Kamala Harris/Tim Walz campaign has been meaningless, but they and it exists. I can give reasons as to why I come to that conclusion and even bring up points to back my conclusion. But it seems to me that folks here want to denigrate God and theists without offering up explanations. This thread is a prime example of that, as are all the threads relating to God. Why is that?
Maybe God exists, maybe God doesn't exist. I don't know, precisely because I find God to be a meaningless concept. I am therefore agnostic. I also consider God to be unknowable, precisely because I think it a meaningless concept.
So why do you engage in discussions about God?
Do you ever engage in discussions about Gliptz?
