You can neither determine true or false in nothing. It’s as simple as that. Your attempt to derive anything out of nothing is the source of contradiction, not nothing.
There is an ambiguity in the word nothing that allows the kind of confusion your points highlight. The word
nothing is a compound of the words “no” and “thing” which can be taken as the absence of something, as in your blank paper example. There is no writing on the paper, therefore there is nothing, i.e., no-thing on the paper, understood as “the absence of what is expected.” This use of no-thing is understood because it is stated with reference to an expected quality.
What ReapReason is talking about is absolute nothingness, the absence of all being. On the surface this sounds as if it ought to be unproblematic because absence and being both make sense and form the ”data" that you asked about previously, just as square and circle form the data of the concept squared circle. The question though, is: Can you square a circle? Even though a question seems on the surface to be possible, the answer for it is clearly, No, because a contradiction arises. The resulting answer is incoherent, no meaning can be ascribed because you cannot have a circle with corners.
A similar question can be formed for absolute nothingness: Can you coherently remove everything and have absolute nothingness? The answer again is clearly, No, because nothingness is not a thing that you can have. It has no ontological status. Nothingness in this sense cannot exist on its own, it absolutely depends on the existence of something. It is a “privation” of being, completely parasitic on there being something to begin with. No-thing makes no sense without a “thing” to be the “no” about.
What ReapReason argued is that a state of absolute nothingness is incoherent (a contradiction) because it is meaningless without presuming something. So something is a necessary precondition for nothing to be meaningful.
Absolute nothingness, i.e., the state of not requiring something, cannot, at the same time, be the state of presuming something, so there is a logical inconsistency, a contradiction, that arises.
Now the case could be argued that absolute nothingness is a kind of “factual” contradiction, as in “after the fact.” A table cannot logically be a chair, but as a matter of fact it might have been a chair if it wasn’t a table. So the question could be asked if absolute nothingness might have existed as a possibility, i.e., the mere absence of everything, simply non-being, instead of the being that we have.
In a sense, it is our understanding of the word nothingness that limits it to a dependence on something, so this is a factual or semantic contradiction. Can we rightfully ascribe to it a kind of ontological status? Can our “factually” limited idea of absolute nothingness force reality to conform to it? Is it a true logical contradiction?
If it is true that “from nothing, nothing comes” then clearly there is a factual case that since there exists something now, there could not have been a time of absolute nothingness, which I think is the crux of the cosmological argument.
Somewhere along the line ReapReason’s argument does a sort of piggyback on the cosmological argument. He may be “skirting” the idea of the possibility of absolute nothingness as
an alternative to somethingness, which is your point.
But is he?
Does it make any sense to speak of the non-existence of existence? That existence
might not have existed?
