Atheist do not believe in a transcendental/spiritual realm. They claim there is no evidence to support. But they believe in the material, because they can see evidence of it. Right?
So you live your life in a world where everything is entirely natural (as far as you can see). Right?
Is that any clearer?
Some atheists do believe in a transcendental/spiritual realm... they just do not believe in God.
So my point is not that ''if we can think of something it must exist'', it is that everything that exists is natural. It is nothing but an expression of the sum total of nature. Clear?
In that way, you (being nothing but nature) are stating that another aspect of nature doesn't exist (as in God) on a day to day basis (until evidence of God arises, you live as though God does not exist). But another aspect of nature believes that God does exist, and live their lives as though God exists. This is also nature (from your real time pov).
So how can nature, deem that nature doesn't exist?
Nature does not deem that nature does not exist... they deem that a specific claim of what nature includes or is (depending on one's concept of God) does not exist.
If one wishes to merely say "God is nature" or "God is the universe" without adding any clothing for that God to wear, then none will quibble with your claim, other than ask why you would want to call it God rather than one of the words we already have for it.
It is when "God" is given clothing to wear that one enters the realm of claims of what nature is (or includes) - if one is suggesting that nature is God / God is nature - and at that point atheists do not "deem that nature doesn't exist" but they perhaps deem that those aspects of nature do not exist that you claim does exist.
Nature is nature regardless of what we claim about it.
I'm sure I've used as part of my definition of God, ''The Cause of All Causes'' so I'm not sure how you arrive at that point.
So you have a concept of God. QED. Your attempt to wave away belief that atheists used to have as mere belief in a concept is thus, by your own admission here, hypocritical.
And if you continue to argue that there is a meaningful difference it will be nothing but hypocritical dishonesty.
Why would there be a need to form a concept of God?
One can not believe in God without forming some concept. Even you have a concept - as you have acknowledged above.
I understand that connection to be God, not that I had some understanding, then decided to create a being to fit.
That's not how theist's think.
So when you concluded on God, you now claim to have had no concept of what you were concluding on, despite your admission not a few sentences before?
As said, Jan, you are running round in circles here.
Skilled musicians know how to evoke feeling and emotions through the mixing notes together. They understand how it's done. Not that they understand what it is they want to achieve, then create a concept that is different to the norm.
Skilled musicians learn that from all the practice they have put in to the instrument. They do not come to that state without it... they have a concept of music, of the instrument etc.
Your analogy is thus woeful.
Oh, so my existence is also a concept?
I am not my body, is my concept also?
I have not said that. But to reach such a conclusion you must have a concept of what your existence is, what your body is etc.
One simply can not form a thought without some concept behind the words being used.
Terribly sorry. You believed in God, now God doesn't exist for you unless He comes to see you personally. What was I thinking? You were a true blue theist.
I was, yes, despite your incredulity.
That initial belief may have been built on shaky ground and easily tumbled, but it was still belief in God.
Yours may be a less shaky belief, and thus you perhaps can not understand how others had a more fragile structure to theirs. But whatever structure we both had, we were both looking at the same view.
My belief collapsed. I am now of the opinion that the view is not what you claim it to be of, or that I used to claim it to be of.
For some reason you see belief as the structure and reasoning, which for you must be, by default, unshakable.
For me belief is not the reasoning for reaching that point, or the structure, but the view once you are there - however you got there.
