It's becoming increasingly difficult to find a common frame, or foundation, of belief upon which to debate.
Heh, I know what you're saying. Nice post, too. Stephen Hawking wrote about this, how we can look back at ridiculous ideas from centuries past (he specifically mentioned a flat earth on a stack of turtles) and think so highly of ourselves, but how will our descendants see the things we believe?
Considering the historical criticism that students have been learning in seminary for a couple hundred years, it's a shock to come out of the Theocratic Ministry School and see what scholars actually know, things we've been taught to dismiss. I am convinced that most elders would not pass the entry exam to seminary, and would not pass the program without abandoning their faith.
And that's just the thing. As you pursue the truth, the truth sets you free. Matt Dillahunty went to seminary as a Christian fundamentalist and now hosts the Atheist Experience in Austin, TX. Bart Ehrman went to seminary as a Christian fundamentalist and is now an agnostic seminary professor, though he insists atheism isn't an inevitable result of Bible criticism. I would say it's either that or some sort of loose, metaphorical reinterpretation. Or just dishonesty.
At this point, I'm atheist but certainly not nihilist. The world is beautiful, and it's a joy to be alive, to write and create and take things in and have an impact on the world around you. I like to think of my personal philosophy as Zen Stoicism, two things from East and West that naturally go together. And I'm certainly influenced by the monomyth of Joseph Campbell. That's just me and my way around nihilism.
