Clarity largely. I find the "lack of belief" definition far too murky to be desirable for general use.So, having read the OP by AronRa, I'm wondering what your issue really is here.
The word atheist is fine if the question is about belief/disbelief. What anyone "claims to know" is irrelevant. It would be odd if every question about what someone believes regarding a particular topic also required that they give an answer about whether they "claim to know."And also wondering why you didn't respond to my earlier post about just laying down the position and then using any word you want for it? Is it just the word atheism that bothers you? Which word would you prefer to use for someone who neither believes in the existence of, nor claims to have knowledge of the existence of anything which could reasonably be referred to as a God?
Yes, it's the same way we "demonstrate" anything—through the application of argument and evidence, discussion, study, etc.I think I see my mistake and I am sorry for being unclear. I am asking how we would go about determining there is a god(s), this is a separate question of whether or not someone believes in it. I can demonstrate that evolution is true regardless of whether or not the person I am talking to believes it or not. Is there a way to do the same for a deity(s)?
