Thanks for sharing your thoughts. I don't mind discussing, but I don't debate.

1. Knowledge is fundamentally spiritual, not rational. The limits of rationality are demonstrable in multiple ways, and it is easy to see that what is called "knowledge" by the rational mind cannot be knowledge at all, if knowledge exists. I think that analysis is more complex, but also demonstrable. Rationality floats on a spiritual sea. Can it be proven? The idea is a non sequitur, because spirit transcends reason and cannot be reduced to rational terms. It is more useful to approach the question of proof itself. All so-called proof is relative, not absolute; the axioms upon which it is forced to rely are themselves unprovable.

2. Divine encounter takes place in the spiritual realm, and is reflected in the rational mind -- kind of like Plato's shadows. Yes, we need to express our spiritual experience in rational terms, but we can never explain that experience in rational terms.

3. "How do we know that we know?" Discernment is strictly individual, because each person's relationship with God is individual. The experiences of other people can be useful, but they are not defining or delimiting. St. Paul encountered Christ on the road to Damascus, but not everyone accepted what he had to say. God, Himself, is His own witness -- not to this or that doctrine, necessarily, but to Himself. The relationship with God is the Truth that underlies all "truth." When you have a revelation or realization of God, you know.

4. See #3.

As for reality ... you have to do what works for you. My purpose in responding is not to convince you or convert you to my point of view, but to show that there are answers to your objections.

If you reflect on Goedel's incompleteness theorems, you can see that all rational thought draws meaning from outside itself. What, then, is the source of meaning? I call it Spirit; you can call it what you like. But there is something beyond rational awareness that gives meaning to thought. The insufficiency of rational thought is everywhere visible; for one, all definitions are, in the end circular, and, for another, how does communication take place? Do people ever really connect with each other, or is it all pantomime? Is love real? These are questions for which reason has no answer.
