I don’t know what a spiritual notion is. There’s a lot of words I don’t really understand. Faith, belief, spirit. They’re intangibles likely measurable by areas of activation in the brain and/or by levels of biochemicals. So I interpret as best I can.
well, there’s a lot of concepts that describe intangible things that don’t correspond to reality in a 1:1 fashion. But they’re useful.
I’ve thought it likely that there’s higher dimensions since I was a kid. Is it part of the physical material world? No. But it seemed reasonable. That’s about as close to spiritual as I can go or vague notions such as “this place needs more candles to be spiritual” – a lighting situation that evokes emotional states. But there’s a number of concepts I don’t understand fully because they don’t really correspond to anything particularly unique in me that I can understand them with.
For me I suspect it’s autism-spectrum related: Bayesian belief notions don’t jive with me. I have confidence levels but I don’t grok belief very well. As a form of hope? Ok. But as a thing-in-itself, it doesn’t compute.
