There is a simple argument that demonstrates how your own analogy works against you. Those in what I shall call Group 1 (that is every person, including you) accept the reasoning that objects A may exist as state of affairs X, where A exists in general experience, but only if both A and X are subject to possible experience. Aliens exist in some part of the universe is a premise subject to possible experience in that we know by what means this could be verified, by space travel for example. But in Group 2 only those of a prejudiced mind or a dogmatic faith also believe that from the existence of A the existence of X can be assumed when only the former is available to us in general experience and the latter is excluded in possible experience. So Group 2 counters its own reasoning in Group 1 in order to make an exception, as a speculative plea from faith, while having nothing in general experience to corroborate it.
But now Ill show what is really wrong with your argument that cause is supernatural (or exists beyond what is natural)
You are arguing to a principle that: A thing that doesnt contain its own explanation must therefore be supernatural in order to state that causality is a supernatural phenomenon. The problem, though, is that could also apply to the world as a whole, since there are lots of things in the world that are yet to be explained. But the world cannot be both natural and supernatural!
We dont understand how the human brain retains information; so we might well say:
The human brain doesnt contain its own explanation
Therefore the human brain must be supernatural!
And it cannot be said: but the human brain requires a cause because everything that exists but doesnt contain within its nature the explanation for its existence must have a cause, as that also implies a cause to explain causality, which is incoherent!
But causality is contingent, and so if God is the supernatural cause of the world and causality is also supernatural, then we have something that has the possibility to not exist as an explanation for something that has no possibility of not existing, which is a contradiction.
Are you seriously trying to say those two sentences are equivalent? We do not know cause and effect apply to the supernatural. In a single sentence youve managed to beg the question and make an argument from ignorance.
This is the sun totality of what the analogy amounts to:
1) They didnt know some fact or facts about the world.
2) We dont know that there is anything other than the world we experience
Note that 2 also applies to 1
And what other realms of reality? (!) There is only reality, the one in which causality actually exists.
What Im saying is your claim is not falsifiable and you have the burden of proof that cant be met, and so its a fallacy because youre making an argument from ignorance, by which anything can absurdly suggest anything. Also if you are asserting that it is a likely truth then that is in the arena of probabilities and contingent truths, which can only be settled by general experience. So explain, without arguing in a circle, where in general experience the supernatural is confirmed?
That is not what contingency means. Even in a colloquial or vernacular sense it only means not certain or possible. Youve written it exactly as you would like to believe it, in order to suit the argument youve been making, which is incorrect. Ive given the definition again below. If you disagree you can always look up the meaning in a dictionary, adding logic or phil to the search criteria, or better still go to something like Wikepeidia for an in depth explanation.
A contingent proposition is neither true nor false. The world is contingent upon God, the Flying Spaghetti Monster or anything else, is a statement that is possibly true or possibly false. So contingent existence means that a thing may or may not be: that is to say without necessity. Whereas A triangle has three sides is a contingently true statement, necessarily so because the concept of a triangle is analyzable by its having three angles.
Everything in nature is subject to cause and effect, which necessarily requires mutation and movement, since one thing acting in relation to another in time is the definition of causality. But there was no time before the Big Bang and therefore causality could not pre-exist the beginning of the universe, and so cause and effect, which acts in relation to time as mutation and movement, is only intelligible after the universe began. Therefore causality began with the world. But if everything beyond nature was somehow subject to cause and effect, then it follows that God would have been dependent upon mutation and movement, which contradicts the notion of a timeless, immutable, unmoved mover. And if God wasnt dependent upon causation then he had no means by which he could create the world. In either case God is impossible.
