Are you saying that it is only what is in nature that exists?
In effect. I'm saying that nature is another word for the world external to the self, where things with objective existence are found. If God has objective existence, that's where [he] will be found. If [he] doesn't, then [he]'s not real; instead [he]'s just an idea in someone's head.
I assume three things ─ and I assume them because I can't demonstrate they're correct without first assuming they're correct. They are ─
That a world exists external to me,
That my senses are capable of informing me of that world
That reason is a valid tool.
Fortunately, anyone who posts here demonstrates by doing so that they agree with the first two, and with ordinary luck the third as well.
From this basis the distinction between subjective and objective is much clearer. To have objective existence, a thing must exist in the world external to me, also called nature.
Whereas mermaids and unicorns and magic and ghosts and souls and "the immaterial" exist only as concepts / things imagined in individual brains.
Are you saying that if there is only one example of a being with all the qualities you mentioned that this being does not exist?
I'm saying that the qualities/properties I listed are not found in nature any more (it appears) than God is.
How are you so sure?
Isn't there something watching the thoughts of the brain.
At least one of our brain functions is overseeing (some of) the workings of the brain. This interconnectivity has been hypothesized to be the basis of creative thought, mixing and matching ideas from one set of concepts, one style of thinking, with another, different one. It's also a fundamental part of human learning.
More specifically on your question, I don't believe there are any absolute statements about reality; nothing protects the best theories of our science from unknown unknowns. Any God will have the same problem, being unable to show there's nothing [he] doesn't know [he] doesn't know, nor that [he] did not come into existence ex nihilo, along with [his] memories and the rest of the universe, at ten to midday Rejkjavik time last Thursday.
You already have a description.
No, no one has offered a description of a real God ─ size, sex, number of limbs, number and nature of sensory organs, metabolism, brain functions &c. Instead, total silence.
