Citing authorities, without mentioning or paraphrasing their argument, is not an acceptable scholarly practice, and you will not find it in professional debates, peer-reviewed journals, and so on. Nice try.
That is not even a correct counter to even one of my five examples, among many. That was at best a get me out of this "hail Mary". Since I could not even get you to respond to what I stated let me make a different illustration. On another site years ago I was debating the certainty of an age of the earth, or an evolutionary claim, or something very similar against 5 or 6 atheists. Back then I worked with peer reviewed engineer who was very interested in these issues. I used several arguments he gave me. No one could counter any of them. Every single person I was debating abandoned every deductive claim and concentrated on only the number of scientists who had adopted what ever views was under discussion. Now the important part is this. I did not yell fallacy to get out of an inconvenient fact. I said despite the weakness of their counter arguments that the numbers of experts who held the conclusions they held was the most persuasive argument they made, and it was. BTW if you make it worth doing I will look up and post that discussion.
No the only use of experts is not in connection with their entire arguments. I have heard on both sides entire lists of experts that simply agreed to a claim or held a position. Of course in many cased their arguments of more often a fragment from it is used, but there is no mandate to do so. Since you did not even attempt to address my other examples there is nothing left to contend with, here.
No, not in the manner you have been doing; i.e. citing the bare agreement as evidence. As I said, citing an expert is hardly fallacious- but you actually need to cite them; paraphrase/mention their argument- not just name-drop and say "so-and-so agrees with me".
It is completely impractical to list every argument (and if done so it must be done in full) of every expert who is cited in a post. I have included a great many of their arguments. In fact another non-theist told me to stop doing so the other day for Craig's arguments. The most effective and efficient way to use scholarship is by citing who agrees with a proposition. If you claim they do not in fact agree then you may of course request I supply their arguments or statements demonstrating what I claimed and I would do so. You cannot by any means mandate I supply every argument of every scholar I use up front and I do not believe you nor anyone else has been consistent with that contrived mandate.
Your claims belie one another; if you've spent any amount of time looking into multiverse models, then you know they are speculative, but nevertheless based on actual data. If you don't know this, then you clearly are unfamiliar with them- can't have it both ways. Multiverse models are, like all scientific models, posited to explain some set of data (in this case, CMB variations, fine-tuning, etc.), and which makes some predictions. Are they currently testable? No, and thats one reason why the theory remains speculative- but it does make predictions (Mersini-Houghtons, Aguirre), and it is based on empirical data- to claim otherwise is plain ignorance or dishonesty. Neither would surprise me in this case.
I have spent way more time chasing down links provided as evidence for them than they deserved. In a philosophic view every additional universe makes God more likely. If you posit infinite universes (which make as much sense as any additional universes) God becomes absolutely existent by necessity, so multiverse are no threat to my views. They are just quite simply the worst science I have ever run across. I notice you not only appealed to authority without their argument but did not even bother with a link. I will track down the best link you have, if supplied, but I am burned out on these false trails and will not go further.
Very convenient for you, then, that my intolerable sarcasm happens to occur during points which you are unable to answer, and so you have an easy excuse not to do so. Very, very convenient.
I never read the points that followed the sarcasm. In fact if you restate the point minus the arrogance I will deal with it.
No, you whined and complained about how I never did what I had in fact offered to do- an offer you refused, BTW. Once again, you can't have things both ways.
I know what I did. I did it. I am the worlds greatest expert on what I did and why. I did what I said for the reasons I said.
"A deductive argument is said to be valid if and only if it takes a form that makes it impossible for the premises to be true and the conclusion nevertheless to be false. "
-http://www.iep.utm.edu/val-snd/
"An argument form is deductively valid if and only if it is impossible that its conclusion is false given its premises are true."
-https://www.msu.edu/user/blmiller/BasicLogic/DeductiveArguments.htm
"An argument is valid if it is impossible for its premises to be true while its conclusion is false. In other words, the conclusion must be true if the premises are true. An argument can be valid even though the premises are false."

We could go on here, since every single source under the sun that we care to pick will say the same thing, but hopefully you get the idea.
I can engage in quote wars if you wish but it is futile:
III Deductive Arguments: Validity and Soundness
When evaluating arguments, i.e. determining whether they are good or bad, strong or weak, persuasive or not persuasive, there are two questions we should ask (1) whether the premises provided appropriate support for the conclusion; (2) whether the premises are, in fact, true. These are the steps taken when evaluating a single argument. When evaluating a complex argument each of the single arguments of which it is composed must be evaluated and then an overall evaluation of how the single arguments fit together must be made.
https://www.msu.edu/user/blmiller/BasicLogic/DeductiveArguments.htm
An argument is considered valid if the premises genuinely support the conclusion. This concerns the connection between the premises and the conclusion, and has nothing to do with the truth of the premises or conclusion. In this sense a valid argument is NOT the same as a cogent argument.
Deductive Validity
I hope you get these are all opinions and worse still opinions that have no possible verification. Instead I would like to do something different. Tell me what claim you can make that is consistent with your own criteria. Make any claim that has a conclusion that is impossible to be false.
There exists no argument beyond the fact we think that produces a conclusion that must be true even if the premise is true and knowable that I am aware of. Every example I saw of a valid deductive argument was of a failure. It either had an unknowable premise, it assumed the truth of a premise, or it's conclusion was not inescapable.
Yeah, none of this is relevant- the question was whether the cosmological argument was logically/deductively valid, which means that it logically entails the conclusion- it does not. And moving the goalposts isn't going to work here.
Common language use and technical semantics many times over lap. When I was discussing logical validity I was not intending to make a statement about a semantic technicality that exists in some form of rigors philosophy. I was intending to convey the deduction was rational and reasonable as is commonly understood. I do not care what the philosophic community officially determines by opinion what a properly basic argument is, a logically deductive validity means, or what the definition is of a necessary being (which no one has ever tested or seen) is.
1. I do not think your official definitions are accurate.
2. If accurate I do not think they are binding on anything even if technically true. They are opinion based agreements used for conventional convenience and are not knowable).
3. They are not related to the permissibility of a deduction, only related to arbitrary technicality based on opinion.
4. I did not realize exactly what you meant. It was not what I was intending to convey.
The cosmological argument is valid even if there are semantic technical objections to it. Now that I understand in what context you are operating I will restate the "official" justification for the argument. I have to find it so it may be tomorrow. I have the justification for each step of the argument listed individually somewhere. When I find it I will supply the "official" philosophic validation for each step even though I hate this kind of crap. That argument makes perfect common sense, regardless of what semantic technicality is appealed to. Remind me if I forget. Even if I do not find it meaningful I do want to provide the "official" justifications for it's steps. I have to leave. I wil try and get to the rest tomorrow.
