Yes, I agree with you. You make a good point. The scientific method seems to be the best method for the job. Of course, we need to be clear on what kind of job we are dealing with. My point is that someone shouldn’t use the scientific method as an ideology, to filter what can be true and not, simpliciter, wholly. That of course would be self-refuting. Perhaps you do not fall into this error, though some of your comments tend to lead this way.
Maybe I was not clear enough. I never stated or believed that the scientific method (observe-hypothesize-experiment-verify - shall we call it OHEV?) is the one and only method to arrive at a
true proposition (I would rather not use the generic word “truth”, because it is too vague). Also I would point out that hypotheses of science are not “proven”, they are substantiated to a certain degree. (I have no idea which remark of mine triggered your assessment that “some of my remarks tended to lead to that conclusion”. If you would be so kind and point them out, I could clarify the misunderstanding.)
Second, when I was talking about abstract systems, I meant the axiomatic structures like mathematics, formal logic, and also abstract games (like chess) etc… In these “mind-games” if you prefer, one proves propositions, by reducing them to the axioms. Let me point out that the axioms can be anything. The only requirement is that they should not contradict each other.
There are also propositions, which pertain to the past. Since the past cannot be examined directly, the usual scientific method does not work. There is no surefire way to separate true and false statements about the past. We must rely on testimonials, but as we all know (or should know) this is a
very unreliable method. No need to go into it at this moment.
Now, the epistemology should be clear. If I need to clarify something further, let me know.
The question is still there: are these two types of reality - physical and conceptual - all there is? Theists think otherwise.
I have never seen a rigorous definition of what this type of reality might be. Words like “spiritual existence” mean nothing to me.
Use reason and the laws of logic. I am not talking about theology proper here which starts from revelation and uses reason to attain further conclusions. I am talking about philosophy which can use basic observations about reality and the laws of logic to deduce necessary truths. And you are right to put the word “faith” in quotes… it is not often understood very well.
Sounds good. As I said before, if one observes physical reality, employs logical thinking starting with the
so-far-known laws of nature, and finds something that points “beyond” the physical existence then it would be a good start. Of course this line of method should avoid all the logicall fallacies. Insofar, I have never seen such an analysis. All of them contained some logical fallacy, sometimes several ones.
Next, a philospoher should be well-versed in the latest achievements of theoretical physics, and build his structure upon that. Imagine, someone coming forward today and presenting a perfect analysis which would logically lead to the unquestionable existence of God (no fallacies either) but he bases his structure upon the assumption that there are 4 basic elements: air, water, fire and earth! Can you imagine the uproar of laughter? I wish to stress this: “if metaphysics is not supported by real physics, it is useless”. Moreover, if real physics contradicts the offered metaphyics, then the metaphysics is worse than useless, it is “intellectually criminal” (sorry for the poetic language).
A real example is that according to our current knowledge (with the admitted caveat that it is never complete) causation is the actual exchange of elementary particles, and also that within the micro-world there is no strict causation. Now, this may or may not be the final word, but as of today, any philosopher who wishes to state otherwise, should be “banished”. There is no “causative” relationship without STEM being present (space-time-energy-matter). As such the proposed “first cause” is nonsensical. The old philosophers (Aristotele, Aquinas, etc) had no idea what the physical reality is all about. They merely speculated about it, and their speculation has been rendered irrelevant due to the development of actual physics. They thought that there is an absolute space and time, and our blob of matter is “floating” within it. They could not have imagined that there is no space and time without matter-energy. For them the question “what happened before the universe?”, or “what is outside the universe?” were prefectly legitimate, valid questions. Today we know that such questions are nonsensical.
So, if anyone wishes to create an acceptable metaphysics, which would include the “supernatural”, they have their task cut out for them. They had better forget about Aristotele, Aquinas etc… and start from scratch.
But even if this endeavor would be successful, and the non-physical and non-abstract reality would be established (thus leading to some unspecified creator), then the question of epistemology really raises its head. You said that it is based upon revelation. There is no such thing as revelation, there are only old, unsubstantiated stories about some alleged revelation. Furthermore these stories are highly implausible, and they do not present any guidelines, how to separate a true proposition from a false one. I am only aware of one so-called “epistemological method” (the quotes are intentional to express skepticism), namely the
authority driven method. Some self-proclaimed authority (for example the Catholic Church) declares that proposition “A” is true, while proposition “B” is false. That is it. Needless to say such an epistemological “method” is just a joke.
