I apologize if I’m repeating previous things in this thread … I skimmed the posts.
**How do we know if a proposition concerning the supernatural is true or false? ** In other words, what are the means or methods of supernatural epistemology?
One principle that is of essential use is, of course, the principle of non-contradiction. Obviously.
God, as defined by Catholics (but don’t worry, it’s also defined this why by many non-Catholics) is
that which has all being. Oh no! Don’t role your eyes! What I mean by this is that all that all positively exists also exists in God (and this includes all that can intrinsically exist, that is, anything hypothetical thing that doesn’t break the rule of non-contradiction). There is nothing that exists that doesn’t exist in God. Things only exist because God made them exist, and since God (or anything) can’t give what He doesn’t have (you could call that another principle that I’m using here) it follows that (given that He created everything)
all things that can exist actually or potentially also exists in God. That’s what I mean when I say God is that which has all being (and as a side-note, there can’t be two such beings, because that would imply that one has something that the other doesn’t have, which by definition is impossible since such a being has everything).
Right.
Since God has all being, He thus also has all knowledge (because knowledge is something that can exist and is thus a being). How do you define knowledge? I guess we can say that it’s the
correct relation that the mind has to existence. Now, the only “things” that do not exist either actually or potentially are those, of course, which break the principle of non-contradiction. Hence,
God cannot know things that break the principle of non-contradiction; that is, He cannot know that them as existing things. I’ll give an example:
People often say something like, “God knows what you would have done if you hadn’t chosen to go through door number 1” (supposing, let’s say there are five doors). But given that you went through door number 1, God doesn’t know
what you would have chosen given that you didn’t go through door number 1. That is, for example, God doesn’t think, “I know you would’ve gone through door number 3 if you hadn’t gone through door number 1.” But such a thing breaks the principle of non-contradiction. This is because it is saying something is actual and purely potential at the same time (which is logically impossible). You see, it’s potentially true that you could have gone through any door, but none of them would ever be actual except one, if you, in fact, chose one. The four other possibilities only exist as past possibilities and never became actualities, so God cannot know any of those four to be actual in any way. They were only potentials, so God can’t saying, “Entering Door 3 is actual in a non-actual way.”
Likewise, God cannot change the past because that would mean He made an existing thing (event) exist and not exist at the same time. Definitely, a crime against the principle of non-contradiction … unless there is
SOMETHING that distinguishes the two things, like one happened in one universe and the other happened in an alternate universe.
Well, I hope that sheds light on your question. I want to honor you, Spock, for your deeply intellectual mind and love for thoroughness about everything. Few people have that.
