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. — Philosophim
There is the question whether a first cause, lacking a precedent, must be eternal. Also, there is the question whether or not an eternal existence is self-caused rather than uncaused.
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... — Philosophim
Following from this we have: a) there is no something-from-nothing, so, no first cause from nothing; b) there is no other thing in the role of a precedent for first cause. Given these restrictions, first cause cannot pop into existence from nothing and it cannot come from a precedent, thus it must be eternally self-caused. But here we encounter a contradiction: causation separates the causal force from the thing it causes, however, in the case of self-causation, this separation evaluates as self ⟹ ~self (self implies not-self), a contradiction. This therefore leads us to claim existence (of the universe) is eternal and there is no 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. — Philosophim
Given: No should and no should not, we have equilibrium as nothing. Given: No restrictions and no intentions, again we have equilibrium as nothing.
I'm not seeing how this is any different from claiming: "First cause popped into existence from nothing."
It's okay to claim: "First cause popped into existence from nothing." Maybe so. I'm only claiming this declaration is not the conclusion of a logical sequence of reasoning. This is an issue because of what your title for this conversation claims: "A Logical first cause is necessary." You can't fulfill the claim of your title until you present a logical sequence of reasoning that necessarily concludes with: "First cause popped into existence from nothing." When you say you establish what a first cause is, you merely define first cause. That's okay to do. However, it's a claim of truth based on words asserted without a logical sequence of reasoning to justify them. Proceeding from here, you claim no reasons for or against existence of a first cause and no restrictions or intentions as to what the identity of first cause shall be. That's okay to do. However, again, it's a claim of truth based on words asserted without a logical sequence of reasoning to justify them.
...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. — Philosophim
Okay. You're saying a first cause is uncaused. I think we agree this is a definition for which logical proof is impossible. An uncaused first exists without explanation. Fine. But don't claim your observation of the unexplainable equals proof of logical necessity. As I cautioned in my previous post, don't confuse the logical decision to merely observe and accept the existence of the unexplainable with the logical explanation of the unexplainable.
If first cause refers to an eternal universe, there follows the question whether anything is caused because everything has always existed, whether actually or potentially.
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?" — Philosophim
Going up an infinite causal regression does not conclude with arrival at a point; the points continue without arrival being possible. For this reason, there can be no
logical assessment of what constitutes a first cause. All you can ever do, given the definition of first cause, is declare it without logical proof. Each time you declare a first cause, you're logically concluding its a concept the existence of which can only be accepted without an explanatory sequence of reasoning. Again, don't confuse your logical conclusion about what you can know and explain regarding a first cause with a logical explanation of the inception of a first cause. Perhaps your conversation title should be:
Concluding A First Cause Simply Exists is a Logical Necessity. Isn't this what you've been saying over and over? If you had used this title in the first place, most folks would've agreed with you and this conversation would've ended long ago.
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. — Philosophim
If something is part of an existing universe, how can it be without precedent? No, a first cause, by your oft-repeated definition: "Something which is not caused by anything else." cannot be other than a new and independent universe. An existing universe cannot spawn a first cause.
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. — Philosophim
There might be a first-cause-as-universe within another separate universe, but an existing universe cannot spawn something not related to itself. So, this appears to be a restriction upon what a first cause can be: it must be its own universe.
You're making the mistake of looking at the universe instead of the causal chain of that universe. — Philosophim
Since I reject logical first cause I look at something similar in terms of uncaused eternal universe.
If something negates itself, its gone. A thing cannot both exist and not exist at the same time. — Philosophim
. That's why there's the question whether or not self-causation is fatal:
"...causation separates the causal force from the thing it causes, however, in the case of self-causation, this separation evaluates as self ⟹ ~self (self implies not-self), a contradiction."
I'm asking you to give me an example of a universe without a first cause in its causation chain. — Philosophim
An eternal universe is an example because it has no beginning and no causation. I can't prove existence of such a universe logically. I can only declare it as an axiom from which reasoning follows. This axiom cannot be derived logically. It is, however, logical for me to conclude that this axiom is a necessary start point for reasoning. Since an unexplainable axiom is a necessary start point for a sequence of reasoning, it's clear the axiom stands beyond the reach of logic.
"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. — Philosophim
Below I reprint an argument you haven't responded to:
...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 [logically] sequenced. — ucarr
Here I'm talking about infinite-causal-chain-as-universe. I'm claiming you can't posit a first cause start point of an infinite-causal-chain-as-universe because any sequence -- once identified as infinite -- has no specifiable start point or end point. My logic is simple: if you can't find something, you can't claim it's either a start point or an end point. If this is true, then your claim a first-cause start point (for an infinite causal chain) is logically necessary is false because the math logic of infinity denies existence of start points and end points within infinite sequences.*
I wonder if you'll oblige my explicit request for you to counter-argue the specific points I've raised here.
*This is even true for infinite sequences that have boundaries. Such infinite sequences lie within specified start and end points, but the volume of the members is a separate thing (infinite) from the extent of the members (finite). Consider the sequence from 0 to 1.
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
This is not a sequence of reasoning. If it were, you would include a list of possible reasons for only one type of universe. All entries but one on this list would be crossed out and a sequence of reasoning provided to explain and justify the exclusions. Instead, it's an axiomatic statement about space and matter used as a premise for claiming there is but one type of universe. It's okay to do this, but it's an axiomatic claim, not a logical explanation.
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. — Philosophim
You think claiming as fact "there is but one type of universe" is reasoning? Give me a logical explanation for your belief. See my statement above (infinity cannot be sequenced) for an example of
reasoning toward a conclusion.
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. — Philosophim
Imagine I don't know that a certain plastic, being a non-conductor, acts as an insulator against the flow of electric current. After repeatedly trying to get current to pass through the plastic to another conductor that completes a circuit that makes a motor run, I run a series of tests and see that whenever the plastic is excluded from the circuit, the motor runs. I therefore conclude, logically, that completing the circuit requires bypassing the plastic. I've made a logical conclusion about a state of affairs I've observed. Indeed, this is logical thinking. However, I shouldn't go forth to other people claiming I have a logical explanation for
why the plastic keeps the motor from running. I'm merely observing
what is happening as an axiom of unexplained truth that the motor doesn't run when the plastic is included in the circuit.*
*A chemist might enter the narrative with an explanation
why the motor doesn't run with the plastic included in the circuit: it lacks the loosely bonded electrons needed to supply the current necessary to complete the circuit.
My example parallels:
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
This is an observation, not an explanation. You have no argument towards claiming logically only one type of universe exists. On the basis of your information-scarce observation, there's no logical reason to conclude there exists only one type of universe. You insist people believe your claim because you say so.
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. — Philosophim
You merely state as fact: "logical necessity of a first cause." There's no explanation why logical necessity of first cause. Your state an observed what; you don't state an explained why.
Maybe you're right that its axiomatic, but can you break it down how you arrive that its merely a declaration? — Philosophim
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. — ucarr
I've put in bold letters what's at the center of our debate: "There is nothing that explains the being of a first cause."
Here we have your fatal mistake in mostly your own words. By definition -- not by a sequence of reasoning -- you state without explanation the truth about a first cause: it's an axiom by supposition. Moreover, it cannot be explained logically because, as you say, "There is (by definition) nothing which explains its being."
