The chair in front of us could not exactly 'fit' the definition; if it did then the definition would only relate to that specific chair. Rather, the definition would name some particular feature of all chairs which we would both agree was present in the object in front of us. You would think that would be easy, but it turns out not to be. There is no general physical feature of a chair that will not be shared by other objects, and if we try to be too specific we will be excluding things that we want to include. Or, we will end up with something circular; 'chairs are things used as chairs'. It appears that words do not refer in that way, that the meaning of 'chair' is not contained in a definition but rather in the use we are making of it when we communicate.Gertie wrote:Londoner
Not sure the chair comparison works, as we can agree a definition of what constitutes a chair (and then agree if we both see something fitting the definition of a chair in front of us).
For example, in this post 'chair' has nothing to do with any piece of furniture, 'chair' is simply serving as an example of a certain sort of word. I understand that, you understand that, but our use of the word 'chair' would not be part of any definition of that word.
I think the problem is that we understand things by putting them in groups; 'a chair is a type of furniture'. But God (in monotheistic religion) is not a type of anything; unlike 'chair' the word 'God' only refers to one thing. And I think religious language reflects this; that God cannot be defined but only spoken about through metaphor, that none of the words we use can be understood in their normal sense. For example, God 'exists' - but not in the sense that material objects exist.Defining 'God' is much trickier, as many people have their own, sometimes idiosyncratic, sometimes not very-well defined, sometimes very obscurely defined, idea of what 'God' is. You can pretty much call anything 'God', and define it how you want. A bit like conceptual art - point to it and call it 'Art' and it's 'Art'. In a sense, everyone creates their own made-to-measure 'God', as I did myself at one time - a God just right for me.
This would seem to be putting 'God' in a special category, so an atheist might simply say they see no reason to accept that category. But - as shown with discussion of 'chair' - it turns out that the categories are not cleanly divided. That we cannot make a clean division of language into (on one side) ordinary sensible words, that refer in a straightforward way to material objects and (on the other) of all the weird language used about God. It turns out that all language is weird.
It is the same point I was making before about the metaphysical concepts that are necessary to underpin physical science. We want to find some sort of a rule, a definition, so that we can explain our atheism. So we can say: 'these ideas pass the test of being sensible, material etc. And those don't, so that is why I don't believe in them'. But we cannot formulate such a rule, because if we apply it consistently we do not just rule out God, we rule out all knowledge. Or, if we make an exception for certain areas, on the grounds that some ideas just intuitively feel right to us humans, that they help us make sense of the world, why can't the theist ask the same, for the same reasons?

But if the message was embodied in something material, then it could not be evidence of a non-material God.Scribbler60 wrote: Well, if you were a divine superintelligence, then you would be able to communicate with a fly. Or a person. How to do it? I'm not sure, but I expect something like a message embedded in DNA that could be decoded, or something similar; something that could be replicated under laboratory conditions, and that couldn't be faked. One would have to be very careful though, as we know that human beings are easily fooled, and we must be especially skeptical about hypotheses that we wish to be true.
Suppose the theist argued that life was already just the communication you describe. That we can look at what is and use it to infer the existence of a supernatural creator. If we do not think we can do this now, I cannot see what extra fact about the world would enable us to do it.
Suppose the clouds parted and a voice said 'Know that I am God'. Science would simply adjust to take that new fact in. It might hypothesise that humans were subject to collective hallucinations, or that an alien life form had arrived, or whatever. After all, many people have claimed they did hear such a voice - but we do not accept their accounts as evidence of God. In a way, we could say that an event like a voice from the sky is fairly straightforward, in that it is just an extrapolation of things we are already familiar with (beings communicating with sound, 'hearing voices' etc.). So maybe God should make himself known by creating something that entirely contradicts all our existing notions of how the universe works? How about 'black holes'? But science simply adjusts to take account of them. How about 'quantum entanglement'? How weird is that! But once again, science simply absorbs it and moves on.
So what is God to do?
