To answer the question bluntly... yes and no
See for me, I don't believe in spirits and souls and all the mumbo jumbo. But I don't speak for every agnostic. Again.... an agnostic is a person that believes you can neither prove nor disprove God. They are not atheists or theists who think they already know.
So some agnostics can find other ways of being spiritual. Some agnostics believe that we do have souls they will just willingly admit that doesn't necessarily mean there is or isn't a God. It just means that they believe there may be a life force behind life itself.
Again Grant,
I have to disagree with most of what you said. You're looking at it from the perspective of someone who needs a supreme deity to give them purpose. You see it as a sad meaningless existance without a deity because you don't know how to live without that. Emotions are not meaningless. True in scientific terms they are just chemical reactions but in our social environment they mean a great deal. Try telling a greaving mother of her dead child emotions are meaningless. I've seen and felt emotions cause actual physical pain. But then what is pain? It's just eletrical messages sent to your brain and the way your brain interprets them. But is pain meaningless?
Not needing to know that there is some deity watching over all 6 billion of us listening to every one of our prayers but wondering why ours isn't answered is liberating. Not depressing. It gives you a sense of control over your life. I know what you're getting at though. You're talking about when times get tough and you can't turn to God. Hard to imagine what you'd do if you couldn't turn to God isn't it?
But that's because that's the way you were taught. That's what you are used to. It's like waking up from the matrix and finding out that there is no spoon. Congratulations... you are now truly responsible for your actions. Now what are you going to do with that newfound responsibility?
Change is tough. But once you start looking at it not as a problem, but as an opportunity to fix the problem you'll be better off. Each person has his or her own journey though. Some people just aren't cut out to be agnostic just like some aren't cut out to go to Harvard. If you're not emotionally capable of living with the possibility that you may not have a supernatural babysitter to help you through life then I am the last one to fault anyone who holds on to that belief.
