Yeah, I know it was long. thanks for your patience. It's just if I only say half of what needs to be said, it has too many holes in it. But if I say it all, it's a truckload dumped on you. Sorry.
The point is that eventually, no matter what the pursuit, evidences ultimately fail. I've read books on the philosophy of science, and they debunk even simple empirical observations. Fascinating stuff, and I'm reluctant to go that far, but I know what they mean. I know Christians get slaughtered because their arguments are not 100% air-tight, but the issue is that they are far superior to anything else out there. The argument is that with so many variables, perspectives, and alternatives, we have to infer to the most reasonable conclusion, even if evidences are less than 100%. The way I said it was "that for any person there are direct arguments for the propositions in question, and given that there is no comparable evidence against them, they must be more probable than not on his total evidence. The bulk of my commonsense beliefs about minds and mental states must be more probable than not on my total evidence." In other words, I have to infer to the most reasonable conclusion, use common sense (not just philosophy and argument), assume certain presuppositions (without which I can hardly jump off the starting blocks), and if the arguments against what I am thinking from those points aren't nearly as strong, I should go with the strongest case.
As far as design is concerned, the idea behind that is that when we see something that shows purpose in the way it works (the proverbial watch on the beach, or even a chair or a car, or a door), we always find out that somebody designed this thing to be a watch, chair, car, or door. From our experience, the things that look like they've been designed and have characteristics of design have indeed been designed. That's intuitive, common sense, and empirical. We can't always guarantee it, but we can infer to a reasonable conclusion. the argument goes: there are critical pieces of the universe that have characteristics of design. Certainly not every piece in the universe (far from it), but big things, in critical places, bear the marks of design. Intuition, reason, and empiricism take us to the most reasonable conclusion: they are possibly designed, and logic would say so. I'm not claiming that necessarily ARE the product of intelligent design, but they sure exhibit characteristics of it. And if they do, it's logical to proceed to the conclusion that not only possibly, but probably they are.
Contingency: As far as metaphysics (the science of being), contingent means it's dependent on something else for its existence. As far as logic, it means it's neither logically necessary or logically impossible. So all Moreland is saying is that the physical states and the mental states don't give evidence of some kind of necessary connection between the two. They more seem to have characteristics of being separate entities.
Corrigible means changeable. Plantinga is saying that we are wise to hold positions, even though they are not ultimately provable (not logically necessary), as long as they make good sense (not logically impossible), and we are willing to change those beliefs as evidence arises, even if we can't absolutely prove how we absolutely know it's true. We infer to the most logical conclusion, and it's OK to do that. We all do.
> The important phrase here is "thus far"
But then you're basing your conclusion not on information or evidence, but on faith that "Well I believe it anyway, and maybe someday resolution will come." You say consciousness is an emergent property of the brain, but, as Moreland said, "no naturalistic explanation postulated thus far has been capable of accounting for how the mental can arise from the physical." If we go with what we know, it will lead us far closer to a theistic conclusion than a naturalist one. But if you want to go by blind faith, then you go the naturalist route.
> " If the explanation is personal, then it is theistic." How so? Did you leave out a couple of steps here? What did I miss?
Because science claims an impersonal beginning, and that there is nothing personal in the sequence until it mysteriously arises inexplicably and illogically from matter (physical stuff). Everything started from mass, energy, or motion—all equally impersonal. And if everything is impersonal, there is no meaning in any of the particulars. Nothing has any meaning.
But if we are going to claim personality, it makes more sense that there was a personal source. In this case it makes sense that man is person, and that particulars have meaning. There is such a thing as purpose (purpose can only exist with a free agent as the source). Therefore if the explanation is personal, then it is theistic.
> "The conditional probability that our cognitive faculties are reliable, given naturalism together with the proposition that we have come to be by way of evolution, is low." Why do you say that?
Because all we have at play in the system is random mutations plus natural selection. And if it's random mutations, I can neither postulate purpose or reliability in it. If my iPhone is playing songs on shuffle, I can never say, when a second good song comes up: "Good decision." It wasn't a decision. We're on random. And if "random" is the only player in the system, even thoughts that come to my head are random. Can I trust them? Who knows—they were by presupposition and definition random. Are they reliable? It's an idiotic question. Anything that arises from impersonal, mechanistic, random processes is by definition impersonal, mechanistic, and random. "Trust", truth, or purpose, are concepts that have nothing to do with anything. We mutate; we survive. Mutations happen at the molecular level, but natural selection happens at the organism level—and the two are both blind processes based in survival. Nothing is "reliable". That's like asking if a cloud formation is "reliable." No, it's random, that's all. Can we trust our thoughts to be reliable beliefs or giving us truth? Wrong question. Not reasonable in the system you've built. It's only reasonable if there is reason in the system.
> This conception could be an illusion.
It could be, but we have to infer to the most reasonable conclusion.
> Do you think Chimpanzees have a soul? How about dogs? Snails? Single cell amoebas? Algae? Plants? Rocks? Have you said no yet? If you have, where did you draw the line, and why did you draw it there?
The question of a soul is a different conversation. Let's not get the two tangled up.
