The modal scope fallacy isnt so fallacious. P4 already makes C contingent while P5 then instanciates P1to that single fact. This isnt done by combining across conjuncts in different worlds. There’s no distributed over conjunction error. Furthermore, the modal feature that grounds P1 could have failed to obtain, therefore admits an explanatory question. You need some sort of independent reason that totality level facts are exempt. Just an observation that P1 is intuition on smaller cases. Now, the burden is on you.
You claim that ive presented a false trillema, but I don’t see how this is the only possible solutions and none of them work. You have to give me another solution.
You asked how a necessary being can make contingent choices: There are two possible responses: 1st, we can reject event causation in favor of agent causation. Your argument assumes that identical causes must yield identical effects which wrongly assumes that a cause must be a prior state that logically entails its effect. The alternative here I present is agent causation where the ultimate explanation ends with the agent as substance not with a collection of prior states, natures, or reasons. Therefore, necessary premises do not force the final choice to be necessary as well. The second, is that explanation does not have to a forcing mechanism. The PSR of my argument only is that a choice has a reason making it rational and non-arbitrary. It does not require that the reason forced the outcome. For example, God chose explanation C as it created a uniquely great balance of good. This is not a necessary creation because he could have chosen different options.
Your problem with my PSR is a straw man, then begs the question, and then misunderstands the relationship between science and metaphysics. I did not argue that the denying it leads to saying the universe is necessary. Instead, I clearly argued that its denial leads to brute contignetism, that some contingent facts obtain without any sufficient reason why they obtain rather than not. Your arguing that contingent fact can be so and still lack a sufficient explanation. So you didnt argue anything and instead just argued its negation. You have given no argument that your theory is true. Furthermore, your claim that C has no explanation does not entail C is necessary. But this is completely irrelevant. It would only be true if weak PSR is false, so i have no clue why you brought this up. I dont kno why ur using a natural premise to go against weak PSR so ur question begging. Your just saying if we don’t assume the PSR, then PSR no follow. That doenst do anything.
You then say a contingent fact could be contingent and still be having no explanation. This just leads to brute contingent facts. ANd you have given no reason for this. A brute contingent fact could have been otherwise, actually obtains, and then there is no sufficient reason for why it obtains. That is not a natural description of reality and it’s just a metaphysical posit that is completely absurd. It says at the foundation of reality, there is an arbitrary surd something that simply is, with no reason for its being so rather than otherwise. If you want to refute Weak PSR, you need to show either: some contingent fact actually lacks a sufficient reason, or that the existence of brute contingent facts is metaphysically possible, and that this possibility is compatible with the demands of intelligibility and rational inquiry. you have done neither.
You then argue science doesnt save PSR. That was not a good reply at all.
First, Weak PSR is not a scientific hypothesis. It is a metaphysical thesis. Science neither implies nor falsifies it. The fact that science works on the basis of provisional and localized explanatory hypotheses is perfectly compatible with Weak PSR. Scientists do not have to posit the metaphysical thesis that “all contingent truths have explanations” in order to study phenomena. But that does not mean that Weak PSR is false. It merely means that science is not metaphysics.
Second, the way scientists search for explanations presupposes something along the lines of Weak PSR. When scientists come across some phenomenon they cannot explain, they don’t say, “Maybe it’s just a brute fact.” Instead, they see this phenomenon as an anomaly which has to be explained. Why? Because the presupposition of rational inquiry is that there is an explanation out there. If brute facts are possible, why not just assume that any recalcitrant anomaly is one?
Third, science cannot discover a brute fact. How can it? It may find out that the existing explanations are inadequate. It may discover that something is causeless or indeterminate. But it cannot discover that there is absolutely no explanation for something. Lack of explanation is not an empirical fact. It is a metaphysical position. Thus, scientific reasoning cannot prove brute contingency.
So either your appeal to science, in fact supports Weak PSR, which is the transcendental requirement for scientific enterprise to be possible. According to your position, it might turn out that reality includes truths which are completely arbitrary. Then there will be no guarantee that rational investigation can proceed intelligibly. Reality might just include irrationalities. The fact that reality was found to be intelligible all this time is merely a lucky coincidence. Weak PSR accounts for the reason why investigation is rational: reality is intelligible. According to your position, intelligibility is an accidental property.
This is not a refutation of Weak PSR. This is what follows from abandoning Weak PSR. This is something you do not acknowledge.
On the OMNIs, first I agree that the definition alone doesn't prove God's existence. I never claimed that it did. The argument proves the existence of something that satisfies that definition: a necessary, concrete, transcendent ground of contingent reality. That is precisely what I defined ‘God’ as. So saying your arguments about me not getting to the OMNI attributes just attacks something I never argued.
I've already conceded that OMINs need further arguments. They aren't needed to establish the proposition as I've defined it. You are attacking the definition rather than the argument that establishes the thing defined.
Here’s the issue: The core theistic claim is that God is the final and necessary ground of all contingent being. Omnipotence, omniscience, and other attributes like these follow from the definition of that which grounds all contingent reality rather than the modal subproof alone. Your objection amounts to a strawman.
You have misinterpreted P1. The proposition is not “every contingent fact does actually have an explanation,” as per the PSR. It is that contingent facts are potentially explainable. But to deny this is to claim that there is a contingent fact that is in principle unexplainable in all worlds. But C is contingent. Now, if C is potentially explainable, then its explanation cannot itself be contingent, or else it would be part of C. Thus,
C is contingent.
◇E(C)
E(C) → N
Therefore ◇N
S5: ◇□N → □N
Therefore, N exists necessarily.
It is not S5 that bears most of the weight here. What step 6 establishes is that if C is explainable, then any explanation must be non-contingent. S5 only converts the possibility into necessity.
In fact, your “unexplained contingent fact” objection isn’t even an explanation but the refusal to explain. It explains neither why C is rather than not, why C has that character, nor why the explanation should stop exactly there. Theism provides a necessarily existing ground; Brute-C provides an ungrounded assertion. Theism wins in terms of inference to the best explanation since it provides maximal scope for explanation and there is no arbitrary termination point. You have no explanation at all.
Your call for probability is misplaced. In metaphysics, “most likely” means best explanation, not probability. If you need a probability calculus for God’s existence, you need it also for brute-C, and you have no such probability calculation available. Not only does the argument state, “if my premises are right, then God exists,” it states that in light of the possibility of an explanation of the whole of contingent reality, there can be no other terminus for explanation than theism. Brute-C is not just an alternative, but explanatory failure.
Any such explanation must necessarily be concrete. There can be no getting away with any abstract object like "2+2," since abstracta have no capacity to be causally/explanatorily efficacious with respect to contingent reality. The explanation must be such that it could stand in an actual explanatory relationship to C. Such an explanation entails a concrete necessary being – God.
All you have done is presupposed that a conditional metaphysical proof must be treated like a probability theorem in order to complain that it is conditional. Yet, all metaphysical arguments are conditional upon first principles. The question at hand, then, is whether or not it is more rational to accept that contingent reality may be possibly explained or that the entire contingent order might just be a brute fact. The latter leads nowhere.
It all boils down to this: while your hypothesis makes it possible for C to be unexplained, Theism accounts for C. Hence, on the only rational measuring stick there is, God most likely exists.
