Honestly the gain from this thread would be for atheists (and others) to think more deeply about their metaphysic and how its logically inconsistent. I'm not trying to pwn you, but I do want to explicitly call out things that are simply not possible. If I come off smug, I apologize.
Fine, I'll concede your point on epistemology and the definition of atheism. That doesn't mean atheists don't have an epistemology that reflects their metaphysic of believing there is no God (and all that that entails). You can't separate those two things and that's the real point I'm trying to make. However, to do that requires the use of logic and a completely fair question is to then ask how does that metaphysic produce absolute principles that govern creation, but are somehow not contingent, but are in fact necessary and objective. There's no rational mechanism for that.
And yes, I saw your responses above, so I get where you stand on this and I appreciate that. But, I do hope however you can get to a point where you will reject atheism and will see that Christianity is the framework for what is real.
This ended up much longer than expected - sorry. . . .
Oh, I am all for thinking more deeply and challenging my own worldview. However, I do believe that having a fully internally consistent system of metaphysics which explains everything is hugely overrated. Having a worldview that offers an explanation and is internally consistent offers zero guarantee of correctness. A fantasy world like in Lord of the Rings could offer something like a fully internally consistent creation narrative and rules and laws explaining the the most fundamental metaphysical nature and characteristics of reality. That, of course, doesn't make it correct.
I want to build on Rocag's first paragraph directly above in my own way -
It seems to me that we all operate with some level of base level presupposition. That is to say we all hold ideas that we do not prove, but rather use as a starting point in order to reason about anything at all. Presuppositions are unavoidable from a practical sense and how we justify them varies.
Take something like a presupposition about the value of inductive reasoning. The sun has risen every day that I have observed, therefore I expect it to rise tomorrow. Seems reasonable and straight forward, right? Of course, I can't see the future. And I don't actually KNOW, the way an omniscient source would know, that the sun will rise tomorrow. But, it is entirely justified from a pragmatic point of view to believe the sun will rise tomorrow. SO - I believe the sun will rise tomorrow despite the fact that I don't actually know that it will because I grant justification to a sort of reasoning which predicts this to be the case.
So, I have my own set of presuppositions. Nothing formalized, but roughly the following: I believe the natural world is our primary reality or at least the reality we have access to. Knowledge comes through observation and reason (empiricism). The universe operates according to consistent laws. Moral systems can be grounded without religion. Beliefs should be proportional to evidence, and in some cases pragmatism. And a reliability of human reason, but which acknowledges its own limitations.
Now, you can go through these and pick them apart. You wouldn't be the first. We are talking about base assumptions which cannot be proven. . . it should be easy to pick them apart.
Hopefully this isn't controversial, but I would say that you also operate using base level presuppositions. And they are equally just assumptions that cannot be proven. Maybe you think they are more justifiable. . . thats fine. But, what are these presuppositions? That the universe depends on God. Purpose and moral truth comes from God. That fundamental laws of reality, nature, and logic are derived from God. You tell me what your presuppositions are, I don't want to put words in your mouth.
The point I am working toward is this. You hold a set of base level assumptions which is your starting point for your reasoning. And those assumptions can only be subjectively justified, but not proven. You simply believe them to be reliable for describing reality. And so when you start from an assumptive position of "Logic derives from the Christian God" its no real wonder why you come to the conclusion that an atheist using logic is borrowing from Christianity.
If you want to make sense of a materialist or empiricist position, then you have to recognize that we don't start from the base assumption that all forms of logic are derived from God. I'm not asking you to agree with my base level assumptions - just saying that unless you are willing to consider reality from a different set of presuppositions, then of course my positions will seem absurd. Your base level presuppositions might as well include that atheism is absurd. And so your comments just become redundant statements about your presuppositions.
And so how does an atheist justify the existence of abstract concepts like logic? I don't have an answer, just ideas. Maybe its simply a material product of human evolution and cognition. Maybe its just a feature of the natural world or necessary in the same manner in which theists conclude God must be necessary. And maybe there is a God who is the source of rules of logic and reason. I don't proclaim that there must not be a God. I'm open to the idea that there could be a Creator - even if I think the Christian description of God is faulty. This takes me back to my original paragraph. I am okay with uncertainty. I'd like to know the answers, but I accept uncertainty as a reality that every person has to deal with. I am much more comfortable with 'I don't know' than I am with accepting a fully internally consistent set of metaphysical laws which I don't actually believe to be true.
