Hello Gabriella,
I‘m afraid I don’t know what point you’re making, but in any case it’s probably something you should take up with Vlad. He’s the who introduced it as a (albeit false) analogy for “god”. It’s an old trick – you take something that observably happens (people experience love – and hate, and grief, and anger, and….) but that’s difficult to explain fully in neurological terms, and then slip “god” in through the back door as if that was an epistemically equivalent proposition. Apart from being wrong on it own terms (it conflates and observable phenomenon with an unqualified speculation) it also produces the problem that the same switcheroo would allow in leprechauns, tap dancing moomintrolls and anything else that takes your fancy: “Love is hard to explain. So are pixies. Therefore pixies”.
As for similar brain functions whether the object that causes them is real or imagined, fairly obviously yes I’d have thought. Think of the horror film trope where lots of scary stuff has happened, then a cupboard door creaks open and the “monster” falls out only it turns out to be a mop. The comely young actress screams with just as much genuine terror before the reveal as she would have done it if had been the monster after all. In short, there’s no necessary causal path from “I’m in a relationship with god” to there actually being a god at all. That’s Vlad’s problem (one of many): all he has is a belief about that, but no means to justify it.
Hi BHS - yes I would agree with you that you can't go from having a feeling or belief to demonstrating to yourself or someone else that the subject of your feeling is real. Faith in gods is belief without demonstrable evidence - especially as the subject matter - the supernatural - can only be defined very loosely if naturalistic terms cannot be applied. It would be simpler if there was clear, demonstrable evidence that could not have any other explanation than god. But clearly not having that evidence isn't going to eradicate faith for many people and not having the objective evidence is actually part of the attraction - not just for gods but for many other idealistic concepts..... or even Trump conspiracy theories about rigged elections unfortunately.
If we cannot employ naturalistic methods to demonstrate concepts, descriptions of ideas such as the supernatural are expressed and defined in many different ways by different people, much like "fairness, justice, equality, power, civilised values". There is no way of demonstrating justice to someone else - you just have to hope they agree with you that they experience justice.
One particular definition of a concept is privileged for a period of time, until its privilege is overthrown by an alternative definition. People influence and define public policy and laws that affect all of us based on their particular definition of such concepts even if we don't agree with their particular definition. So given we have a place in society for such undefined concepts, gods is just another idea to add to the list, if the idea gains traction or has public support.
Whether gods can be demonstrated to exist or not - and given we lack a method to objectively prove existence for things that cannot be measured or detected using the tools of science - atheism seems a perfectly reasonable approach until you feel a personal conviction to the contrary, which may never happen. I find many personal convictions that other people hold on many different topics unfathomable.
I think atheists and theists have an increasingly easier time figuring out a way to co-exist in society today, much like the majority of theists of different persuasions or people with different political affiliations co-exist. It's only extremists that cause problems for the rest of us. The number of traditional Labour voters who voted Tory in the last election, or the number of Republican voters who voted for Biden
https://eu.usatoday.com/story/opinion/2020/11/02/mccain-why-republican-votes-biden-column/6113484002/ even if all their other votes for the Senate and House of Representatives were for Republican candidates shows that people increasingly make pragmatic choices rather than hold blind allegiance to a single party or religious denomination. I think the less blind allegiance to a cause or idea, the better.
