"Nothing" in this context can be read in multiple ways: a) nothing as in no cause of space; b) nothing as in nothingness, a something that caused space, in which case the infinite regress towards a true first cause is under way; c) nothing as a category which includes logic, so first cause cannot be logically necessary. — ucarr
The intended way of reading it is a).
My central point continues to be the claim no causation precludes any type of sequence, including something from nothing. — ucarr
We're in agreement here then. I'm not claiming something comes from nothing. A first cause doesn't come from anything. I'm just noting that prior to a first causes inception, there is no prior causation or 'no thing'. Nothing is not a 'thing', but the absence of anything.
Also, it should be noted that a causal chain exemplifies logical continuity as expressed: A ⟹ ~A = False. In English this sentential logic statement translates to "An existing thing does not imply the negation of itself." Following from this, claiming causeless first cause tries to equate sequence with the negation of sequence, the definition of first cause. — ucarr
A first cause exists, it does not negate itself. If it did, it would be gone. I'm not understanding how you see a first cause implies its own negation.
I haven't forgotten your argument that before first cause a potential first cause can be anything, no restrictions and then, after inception of first cause, logical sequencing and its limitations are in effect.
This is an incomplete narrative of how first cause incepts because a declaration stating first cause can be anything in no way explains and justifies inception of first cause. — ucarr
You have my logic backwards. I'm not saying anything can be a first cause, thus justifying the inception of a first cause. I first establish what a first cause is, something which is not caused by anything prior or else. The consequence of this logically means that prior to the inception of a first cause, there was no reason why it should, or should not have formed. And if there is no reason why a first cause should or should not have formed, there is no limitations or rules that shape what a first cause should, or should not be.
If, as you say, even an infinitely regressive universe entails logical necessity of a first cause, that's merely saying in different words that: Everything, even an infinite universe, must have a beginning. In this situation of the causeless eternal universe, you're building a contradiction because there's no nothing for first cause to incept from. — ucarr
No, I am not saying everything needs a beginning. Again, we're taking the entire set of the eternal regressive universe and asking, "What caused this to exist?" The answer is nothing besides the fact that it exists. Thus a first cause.
If you're postulating an infinitely regressive universe that contains local first causes, then you're constructing a contradictory universe because if there comes into existence something causeless, then it's necessarily another, independent universe. — ucarr
No, its another separate causal chain inception. A first cause is the inception of a causal chain. When we're talking about 'the universe' we're implicitly talking about, "What caused the universe," What I'm noting is all causal chains have a point in which we reach an 'end', or the start of causation. When looking at a regressive infinite universe, we're going up the causal chain until we get to the point in the chain where we ask, "What caused an infinitely regressive universe to exist?" And the answer is, "Nothing, it exists without any prior causation." Thus the first cause.
Anything contained within the causeless universe cannot be first-caused because, being a part of a causeless universe, by definition it cannot be separate from said causeless universe. — ucarr
Anything within a causal chain caused by something prior cannot be a first cause. But this does not prevent something outside of that particular causal chain from appearing and starting its own causal chain.
Furthermore, the independent universe as first cause is building a contradiction because -- again -- in the situation of an eternal universe, there's no nothing for a first cause to incept from. — ucarr
The real contradiction is nothing that something else creates a first cause. It is completely in keeping with logic that the inception of a first cause entails nothing prior causes its inception. You're making the mistake of looking at the universe instead of the causal chain of that universe.
You still haven't addressed the issue of the paradox of an eternal existence being self-caused. If a thing causes itself, then simultaneously it is and is not itself. This is a logical argument against existence of first cause. — ucarr
Can you explain this? I'm not sure how you arrive at this conclusion. If something negates itself, its gone. A thing cannot both exist and not exist at the same time. How do you conclude what's being said here leads to this?
Also, in the situation of an eternal universe, the start point cannot be ascertained; it's impossible. Well, if a start point is impossible to ascertain, then logical necessity of a first cause it likewise impossible to ascertain. It can only be supposed axiomatically. — ucarr
You are confusing the "start of the universe" with the "start of the causal chain". The start of the causal chain is taking all the causation within that universe and putting it in a set. Then asking, "What caused this set?" Nothing. There is no prior cause.
Let me give you another example which might make this more clear. Lets say that there IS something which causes an eternally existing universe to be. There is an existence A which is able to retroactively cause an infinitely regressive universe B. Is this somehow less contradictory? And does it escape the inevitable question, "What caused A?" The answer is no to both. If you are stating that my conclusion is wrong, then you have to accept the alternative situation. This is what I'm trying to get you to see. All you're doing is noting, "A first cause cannot exist with an eternal universe," but you're not examining what that must necessarily entail if this is true either. Its why I'm asking you to give me an example of a universe without a first cause in its causation chain.
In the case of an eternal universe, you cannot talk rationally about nothing (or anything else) causing the universe to exist because it's impossible to ascertain any logical reason for its existence. This is so because reason_cause imply sequence, but infinite value cannot be specified and therefore cannot be sequenced. — ucarr
As I've noted, we can do this by taking the set of causation within the infinite universe and asking what caused the set.
Are you noticing how I always support my assertions with potentially falsifiable arguments? I never claim that such and such is so because my words say they are so. You do this over and over again. Your claims in this thesis always terminate in claiming it is so because the words you write say it is so. Your central claim is not potentially falsifiable — ucarr
Its very falsifiable. But I have yet to see its false. My arguments conclude it is true. That's very different from it not being falsifiable. As I've noted above, I've tried to say, "Assume it is false, what do we arrive at?" The frustration Ucarr is your inability to demonstrate it is false so far. Which is fine, keep trying. If it were clearly false, we would not be still having this discussion.
Why did one type of eternal universe exist, whereas another universe does not? There is no answer besides the fact one type of universe, space and matter, exists.
— Philosophim
It is not a presupposition, its a conclusion that we arrive at...
— Philosophim
In your example, there is no arrival and no conclusion; instead, there is an observation and a declaration without any reasoning toward it: — ucarr
You know this isn't correct at this point. This is frustration. Don't let that win. I've laid the reasoning out clearly at this point.
There is no answer besides the fact one type of universe, space and matter, exists.
— Philosophim — ucarr
You see Ucarr, the argument's conclusion is logically necessary.
— Philosophim
Don't confuse the logical decision to make an unexplainable observation axiomatically with logically explaining the content of that observation. You're doing the former, not the latter. — ucarr
If you're going to assert that, you need to demonstrate that. Otherwise this is just not wanting to accept a conclusion.
He [ucarr] doesn't like the idea that there was nothing, then something.
— Philosophim
I don't accept the claim: "Something from nothing" declared without explanation proves logical necessity of a first cause. — ucarr
Just to repeat, I am not claiming this. You have the order of logic backwards. First comes the logical necessity of a first cause, then comes the conclusion that this means the inception of a first cause cannot be explained by anything else, thus there is nothing prior which could cause a limit on what or would not incept as a first cause.
What I'm trying to show him is that an eternally self-existent thing is no different. There is nothing which explains its being.* No limitations on what could have been besides the fact of its existence.
— Philosophim
Generally, I accept all of this. Specifically, I don't accept an axiomatic declaration as a rational explanation of the logical necessity of first cause. — ucarr
Maybe you're right that its axiomatic, but can you break it down how you arrive that its merely a declaration? Let me give you an example. A declaration is "A". I could easily state, "Not A" and as far as declarations go, both are viable. But what I'm noting is that if you start with "Not A" it necessarily leads to "A", and if you declare "A", it necessarily leads to A. That's not a declaration, that's a proof where we conclude A must be true.
“When we say that a set is finite or infinite, we are referring to the number of elements in the set, not to the "extent" (putting it roughly) of those elements.” — ucarr
Correct.
The critical question pertinent to our debate is whether or not you can talk logically about the before or after of a bounded infinity. When talking logically about the start of a chain of causality, you’re talking about the beginning of a continuity. That’s talking about the extent of a series. Since the infinite number of elements populating the series precludes you from ascertaining a start point, you can’t claim logically that before the start point there were such and such necessary conditions because you cannot specify a start point. — ucarr
Your mistake is that you are looking inside the set for a start point. The start point is not inside the set. It is the question of what caused the entire set. If I have an infinite series of decimals vs an infinite series of whole numbers, they are separate infinites in what they express correct?
As an analogy, I'm asking, "What caused the universe to be a set of whole numbers vs a set of decimals?" The answer is again, nothing. There was no outside cause which necessitated it be whole numbers or decimals. There is no outside reason which caused an infinitely regressive eternal universe to be composed of space vs water. There is no outside reason for the eternal universe to exist in such a way where a big bang happened, vs none at all. And remember, if you deny it, give me the alternative Ucarr. If I'm wrong, what does that entail, and does that make any sense at all?
It's illegitimate to do so by simply making the declaration: "This is the start point, and before the start point there was nothing, thus the start point examples an uncaused start point, i.e., a first cause.” Doing this examples arbitrarily marking a start point by decree — ucarr
Again, the mistake here is only looking inside of the set for causality. The causal chain extends out to include the set itself. This is not by decree, but the natural next step in going through the chain of causality.
