Is the Idea of God's Existence a Question of Science or the Arts?
I think this is a great topic, especially in comparison to the hoards of boring Theism threads; In fact I really never engage in these discussions anymore, but here I go.
Part of my enthusiasm is because, while reading your OP, I came to a realization that I think is relevant to the topic. I was raised in a Christian environment, and no longer identify with that or any religion. But the typical anti-religious, anti-theistic rhetoric we see so much here still rubs me the wrong way, and I think I finally know why. Hopefully this could be useful to the discussion.
Very simply, the God that atheists criticize on a philosophy forum is not the God that the masses pray to in church. There's a complete lack of communication between the two camps. They talk past one another. Armchair TPF atheists generally don't know much about Sunday morning aunts, and Sunday morning aunts generally don't know much about armchair TPF atheists. And I think you brought up a few pertinent points as to why this is, i.e.
the philosophy of religion developed in a different era. Influential writers, like Augustine and Aquinas were writing with a different understanding of the universe, as were the Biblical writers. — Jack Cummins
people being encouraged to focus on happiness in an afterlife, has lead to many rejecting the idea of 'God'. — Jack Cummins
there are still questions about where life came from and why did consciousness evolve. — Jack Cummins
This is a complex milieu. There are no easy answers, no smart-ass one-sentence (or one emoticon) responses so common to some of the atheist regulars here.
To me, the question of whether God exists is
not important. I don't care. But I'm not an atheist. What I do care about is the Sunday morning aunts, and the armchair TPF atheists. I worry about the lack of communication, the complete otherworldliness of their dispositions, despite the fact that they're all the same type of human being. There's a grave misunderstanding underlying this whole theism/atheism debate, and it's costly.
