You know, we should add links to threads on the brain in a vat thing to the FAQ thread. Unfortunately, I can’t look up “vat” in the forum’s search engine because it won’t look up anything less than four letters long. :glare:
“I read many works regarding Objectivism and listened to Objectivist philosophers . . .”
Such as? You’ve got to be more specific because some sources are much more reliable than others and they cover different topics.
“but how could you affirm that if you exist inside the matrix? What if you’re just a program and you don’t really exist outside the Matrix?”
Do you have any evidence to suggest this is the case? If not, then don’t worry about it. It’s about as credible as there being purple unicorns in a fight to the death underground in one of the moon’s of Jupiter. That one can imagine something doesn’t mean it must be “possible” – we can imagine all kinds of ridiculous junk. The burden of proof logically rests on somebody who says something is or “may” be the case. It isn’t up to others to disprove whatever random claims somebody may spew.
“If you believe that everything is governed by natural law than whatever causes Neo to dodge bullets has to be also governed by natural law.”
Yes. I already stated the machine running the Matrix would have to be operating naturally, not “supernaturally.” I already mentioned before how it is possible to use natural things to present an image which some may mistake for something impossible, like sawing a lady in half without killing her.
“You cannot say that there is probably a World outside if you believe you live inside the bounds of nature.”
Supposing one had the kind of evidence and experiences that Neo did in The Matrix, why not? Throughout that whole first movie there was nothing which happened which could not have been the product of natural occurrences. The Matrix itself and the world outside it - neither were supernatural, both are the product of the natural. For something that you may be more familiar with, have you not had a dream before where it seems like something is not how it should be and asked yourself if you were dreaming as a possible or even likely explanation for what seems to be happening? One has not stepped outside the bounds of nature when they dream. The weird things we may see when we dream are the result of our brain working according to its nature.
“You can only say that our knowledge of nature is incomplete and we don’t know how Neo does his thing.”
Also possible, but various things could happen to raise the suspicion that one may be in a virtual reality program of some sort - glitches, getting chased by fishy agents, hearing rumors about the program and, you know, actually taking a pill that takes you outside the program. A brain in a vat type situation just isn’t a reasonable quick assumption any time you see something you don’t understand, like every time you go see a magician in Vegas you start looking for an exit from the world.
I’m not going to entertain the idea of what to do if one really experienced the supernatural though since, as I explained earlier, the supernatural is impossible due to inherent contradiction and therefore one never would experience supernatural things. If you think you did, you just are missing part of the story that explains what happened and how, like where that rabbit was before it was taken out of the hat.
“If a donkey started talking that would be totally normal as well, because everything is normal…”
Natural and normal are not the same thing. A talking donkey would not be normal, however if you look around you may find a hidden microphone or that this is some weird genetic experiment animal with a different kind of vocal chords and such from other donkeys so that it is capable of mimicking the sounds of human languages much like some birds can.
“We assume nothing can interact with Nature, but isn’t that just an assumption?”
There’s no assumption. Nature, as it is meant in this discussion (as opposed to the usage of the word which only refers to things which have not been created through human intervention) is everything. There is no other, separate thing for nature to possibly interact with.
Not sure what the big bang theory has to do with this discussion. That would not be supernatural either.
There is nothing which exists outside of nature though. Assuming we mean by “nature” here that things are “natural”, ie, that they have a particular nature (a specific identity), then for something to be outside nature would have to mean it does not obey itself, it contradicts itself, it is itself and it is not itself simultaneously and in the same sense. This goes against the axiom of identity as mentioned earlier, that a thing is itself. One cannot possibly present a coherent defense of contradictions existing either because all communication rests on the law of identity. Proving yourself right would then simultaneously invalidate all your previous argument in favor of contradictions and thus leave you again with no case. Throw out the law of identity as an absolute and your words could no longer convey any meaning. You can speak as clearly as you want but there’s no guarantee what those words intend to convey. You can say green and mean dog, pizza and mean liquid, stop and mean go, et cetera since things can be themselves and not themselves at the same time. You just become incoherent.
“Supernature” IS within the realm of philosophy because it is an issue related to metaphysics and epistemology. If you realize something is impossible, you know trying to actually go physically hunt it down would be a futile pursuit.
