I see no need to call myself spiritual.
Yes, I can appreciate a sunset, or some good organ music, or most of the stuff included in the whole 'let's take "spiritual" back' stuff, but... why would I call it 'spiritual'? Even skipping the etymological connection to "spirit", i.e., soul, the fact is that it's not what the "spiritual" folks use it for anyway. Almost invariably it does seem connected to "spirit" de facto, via some woowoo or another. Or let's put it this way, they don't mean going to church just to be in awe of the acoustics of an organ concert.
So I seriously don't get this whole 'oh, I'm spiritual too, even if I have to redefine the word for that' meme.
Yes, there seems to be this 'oh, atheists are not spiritual' meme it answers to, and it's implied to be something bad or lacking, but... so what? No, seriously, why would I want to answer that by trying to fit in with the woowoo gang after all?
It's like being somewhere in the Eastern Bloc in the late 80's and countering the charge that there's something wrong with those who don't like communism (no, really, they even has it filed under a form of schizophrenia in the USSR), by pretending to be a communist too, just, err, in a different way. Why? The ones who actually made a difference were those who could say, "screw that. No, I'm not."
Well, that's not even an accurate analogy, because those at least pretended to be communists too to avoid some consequences that would be pretty brutal. Whereas the gang trying to fit in the 'spirituals' is apparently just in it for... fitting in with the 'spirituals'.
But anyway, screw that. No, I'm not.
Yes, I can appreciate an organ concert or the acoustics of a cathedral, but it's for just that, not because it makes me feel like there's some higher power watching over me. And I can appreciate the cathedral too, but not because it makes me feel closer to some woowoo deity, but even just because it's awe inspiring that they could even make buttresses that worked in an age where they didn't even have the vector notation we'd use nowadays to calculate that. And if I feel there is a greater power, a Logos of the universe as the Greeks used to call it, I'll just call it physics or social dynamics or whatever appropriate. And awe inspiring as it may be, I won't think it watches over me, nor think it's some kind of Santa that owes me something for appeasing it. And I might feel in awe about how we came to be or where we going, but not think there's some God that'll make everything right, and that we can crap all over the environment because, hey, he'll come back before we're done with that. Etc.
Am I spiritual? Not one bit. I can just have all the good parts without all the woowoo baggage.
