Before we go any further, I do appreciate your non-confrontational style and also your line of questioning.

This is the way we can (hopefully) learn from each other.

Either you think that science can answer every question (scientism/positivism) or you think it is completely useless (fideism/fundamentalism). How about a middle ground where you accept science but accept that there are questions that are outside it’s reach? This seems reasonable to me. Scientism is a philosophically untenable position, as is fideism.
I agree that this would be a false dichotomy. Science does not attempt to answer a lot of questions.
Some of those questions are subjective. An example: 1) “why does Joe prefer vanilla flavored ice-cream over the chocolate-flavored one?”. This question pertains to the objective, physical reality, and yet, science cannot answer it – and even if it could answer it, no one would care. But the knowledge is useful, if you wish to give Joe a present by inviting him to an ice-cream-parlor and wish to order for him.
Also, we need to exclude the questions pertaining to the axiomatic systems. One cannot experiment to decide if a proposition within an axiomatic is true or not. If it can be reduced to the axioms, then it is true, otherwise it is not true. (Observe: “not true” does not necessarily mean “false”).

Therefore, any immaterial realities would necessarily be outside the scope of science. Many people will tell you they have no reason to believe that there are immaterial realities because they haven’t been observed. Aside from there being logical reasons why immateriality is real, they are using a material method to search for immaterial realities. Kind of silly if you ask me. And yes you can assess how something that is immaterial can correspond to reality or not. It is either logically consistent or it is not.
Yes, here we start to deal with the crux of the problem.
The number one objection is that just because some set of propositions is internally consistent; it is not true that it corresponds to some “reality”. The “realm” of children’s fairy tales is internally consistent, but no one asserts that the world of witches, dragons, fairies is “real”. It is an
imaginary world, with no connection to reality. So, you see, the internal logical consistency is
not enough to decide if the proposition refers to “reality” or not.
The second problem is that the word “real” is undefined. What does “immaterial reality” mean? One could say that ideas, concepts, abstractions are examples of “immaterial reality” (and that is a philosophical assessment), but then some problems arise. Many critics of science operate under the false impression that materialism considers
all reality to be “physical
objects”. And that is not true. Physical objects have “immaterial aspects” to them. These are “
properties” (“red” or “sweet” are not physical objects), “
activities” (“walking” or “thinking” are not physical objects) and “
relationships” (“behind” or “next to” are not physical objects). Yet, none of these properties, actions and relationships exist independently from physical objects.
Since I don’t know (yet) what you mean by “immaterial reality”, I will have to stop here, and wait for you to clarify.
balto:
BTW, God, angels, and demons cannot be observed with physical sensation for obvious reasons (well at least if they do produce physical sensations they are not reproducible). How about using your immaterial intellect and reason to determine their existence and qualities? That seems like a more reasonable course of action.
Sadly, it is insufficient. If you wish to exclude the physical “imprint” then there is no difference between a “seven-headed, fire breathing dragon” and a “demon”. How does one decide if one is “real”, while the other one is false? You need some
actual, physical starting point upon which you build your conclusions. And here we arrive to the next stumbling block.
balto:
I would only accept B’s opinion as dependable if I had a reason to believe they had credibility.
There is a minor misunderstanding here. Obviously you need to establish credibility. (How you do it, is a different question, to be explored later.) The question was “does the person offering a criticism have sufficient knowledge about the subject to be criticized”? How can you decide if someone has sufficient knowledge to make valid criticisms about Christianity (example only; it could astrology for all I care)? We deal with the problem of “
authority” here.
Do you consider “A” who has a very thorough knowledge about Christianity and also believes it correct – to be a valid authority? Do you consider “B” who can demonstrate the same level of knowledge but rejects it – not to be an authority? You see, if the only necessary requirement is the level of knowledge, then you cannot decide between
competing authorities. In such a case you need to resort either (1) to accept the one who supports you (subjectivism), or (2) tossing a coin (random selection), or finally (3) to the “dirty” verificationism to find out which one of the authorities can support his assessment.
