I'm asserting one must be aware of such a concept to either believe it or disbelieve it, and there is no such a thing as a lack of belief in God in a baby without first a belief in God. A baby cannot have a lack of belief in God because that asserts that a baby is deficient of something or does not have something....which creates a negative position. That's why there is a third category, a default position. Basically you have a scale, with atheism on the left, a neutral position in the middle and theism on the right. Because again, atheism cannot exist unless theism does. Both theism and atheism create such a contrast, and if there is a contrast of beliefs then that makes a middle ground.
Not true. Atheists can exist without theism or theists, if there are people who aren't theists then they are by definition atheists. They wouldn't know they were atheists, but they would fit the criteria to be atheists. They would be people who lack belief in god. I fail to see why this presents an issue for you. The Oxford dictionary defines an atheist as someone who disbelieves or lacks belief in the existence of a god or gods. The Oxford dictionary defines lack as:
NOUN
mass nounusually lack of
The state of being without or not having enough of something.
‘there is no lack of entertainment aboard ship’
VERB
[WITH OBJECT]
Be without or deficient in.
‘the novel lacks imagination’
Note that both the definitions for lack given accept that to be without something is to lack it. Are you suggesting that the Oxford Dictionary isn't using the Oxford Dictionaries definition of lack in its definition or atheist? Or are you suggesting that we can not believe in god while also not being without that belief?
But that is how it is defined, "Disbelief or lack of belief in the existence of God or gods". My claim is that there cannot be a disbelief or a lack of that belief, which would require the missing of something. A baby is not missing a belief in God, they simply can't have belief either way. Again which is why we have a neutral category.
A baby is without belief in the existence of god.
VERB
[WITH OBJECT]
Be without or deficient in.
‘the novel lacks imagination’
so by definition, infants lack belief in the existence of god unless you are saying they believe in the existence of god.
They are not lacking anything, they are neither having nor missing something.
Then you wouldn't say that not having something is to be without it? You're really making some efforts at linguistic acrobatics at this point.
They neither have a belief nor a lack of belief. And lets not pretend that atheism is not defined as a disbelief.
I am pretending nothing. The fact is that by definition all that is required for one to be an atheist is that they be a person who disbelieves or lacks belief in the existence of a god or gods, as defined by the Oxford dictionary. The oxford dictionary defines lack several ways, but they all include being without as sufficient. As such being a person and being without belief in the existence of god fits all the necessary criteria to be an atheist.
I'm saying there is a default position, with theism and atheism being positions.
If the default position is anything other than the belief in the existence of a god or gods then it's a lack of belief in the existence of a god or gods, using definitions I've shown above cited from the same source as the definition for atheism we've both been using for a while and is as such atheism.
to be deficient or missing
to be short or have need of something
deficiency or absence of something needed
something missing or needed
A baby is not lacking belief in gods existence or disbelieving it, an atheist is. A baby is in a position of not missing anything, it is not lacking anything, and it does not disbelieve. It is agnostic if anything, do you make the claim agnosticism is not a usable term? if it is, could you please explain why a baby is not an agnostic?
Where did you get that definition of lack? Because as I've shown above the oxford dictionary definition is clear that being without something is to lack it. Since the definition of atheism I've been using is drawn from the definition in the Oxford dictionary and you seem to have been using the same definition, it stands to reason that the oxford dictionary's definition of lack is what they mean. Or do you suppose they use a different definition for lack?
Agnostic
Oxford Dictionary.
Notice that this is an active belief. Infants can't logically be agnostic any more than they can be theists unless they have a concept of god. Yet that can be without belief in the existence of any god, regardless of their knowledge of the concept of god. In fact if they have no concept of god, they can't help but be without belief in the existence of gods, that makes them atheists.
