I thought of a way to illustrate what my major problem is with this criteria. Lets say we are given an argument X. You say it is invalid according to logical validity and I say your understanding of logical validity is incorrect. Exactly how do we tell who is right.
The same way we would settle it if I said X was a triangle and you said it was not: we'd open some sources on logic, and we would find that all of them say the same thing- validity is when the conclusion of an argument follows from its premises.
For example the claim that the universe is not infinitely old is valid
Only "valid" in a different sense of the word "valid".
Do you think I do not understand what you are saying. I am saying I understand it but do not concur. I think there are many truths that would not survive the technicality wars waged against them. In the exact same way false claims can be "approved" by a criteria and be perfectly wrong. I like philosophy and science but as in all subjects it always gets pushed beyond competence. The same is true with the fact most people get promoted one level beyond competence. I understand what your saying but I do not agree with it as a criteria valid for truth.
It
isn't a criteria for truth. Validity and truth are related, but not the same. But if you understand this simple point I'm making- about validity being a necessary but not sufficient condition for a sound deductive argument (and a good deductive argument being one that is sound, or at least probably sound) then so much of what you've said is
irrelevant. More likely you just want your cake and to eat it too.
The cosmological argument is not a claim to certainty. It is a claim to logical consistency or best fit. It is logical, rational, justifiable (informally if you wish to split hairs) but has existed in formal debates and considered among the best arguments for God in academia by those most experienced with technical philosophy. In recent research I read it is the most debated argument concerning God in western culture. In (maybe) hundreds of formal debates I have seen or read I have never heard a single atheist claim the argument is technically invalid. They usually simply claim it is uncertain or other explanations can exist. To be fair they are usually not professional philosophers but are scientists or physicists.
Most of this is not relevant- what you think people say or think about the cosmological argument has no bearing on whether it is valid, sound, or compelling. It is none of these, because of the simple fact that its premises could be true, and the conclusion false.
Talk about futility of repetition. I have granted the technical basis for your objection. I just deny it's authority. Tell me something. In what field or on what basis is the criteria for logical validity useful?
Any in which deductive inference is involved.
I have said time and again each step of the argument has an individual validity or reason for acceptance. It would be very rare for a complex argument to have an identical reason to accept it's every step. There are just to name a few deductive validity, inductive validity, non-contradiction, soundness, properly basic, evidence, causal reasoning, elimination of possibilities (in known sets), inferential logic, related rates, modal logic, and even persuasiveness alone (which is hyperbolically arbitrary. Let me illustrate why I do not like these technicalities of philosophers.
Hume said: Does it contain any abstract reasoning concerning quantity or number? No. Does it contain any experimental reasoning concerning matter of fact and existence? No. Commit it then to the flames: for it can contain nothing but sophistry and illusion. - An Enquiry Concerning Human Understanding
Besides being complete crap the statement is self condemning. I do not have time for that garbage.
Someone told Craig and Plantinga that belief in God was not properly basic because it was not self evident. Now let's pretend they were right to begin with their comments dealt with the application of the standard all together.
Their response from Craig's: A reasonable response.
1. Of only self evident and incorrigible positions are properly basic, then we are all irrational, since we all commonly accept numerous beliefs that are not based on evidence and are neither self-evident nor incorrigible.
2. The proposition that "Only beliefs that are self evident or incorrigible are properly basic" is not it's self self-evident nor incorrigible.
A criteria that cannot survive it's self leaves me writing the credibility of the one who states it off entirely. There is no test for these claims. We can't go check and see if they are true. I think while they may have value their use as an arbiter is way over employed.
How is this response not guilty of it's own accusation. I was pointing out the fact that the technicalities dreamed up by philosophers do not necessarily apply top all arguments and do not always correlate with truth.
This is called "throwing a whole bunch of ***** at the wall and hoping some will stick". Good gravy, what on earth is going on here? Talk about all over the place and confused... Fortunately, none of this is really relevant at all, so we'll just move along.
Trivial or not that argument and the cosmological argument have a reasonable premise and conclusion.
"Reasonable" is very vague.
The cosmological argument is not valid- that is, even if its premises were true, the conclusion would not follow.
It's premises are also neither true nor probably true, but appeal to facts not in evidence/are extremely contentious/are extremely speculative. But since it is not valid to begin with, the truth of the premises is sort of a footnote only, since they could be true and the conclusion would nevertheless
not follow.
What is the standard for goodness?
Of a deductive argument? Validity and true premises (i.e. soundness), and pertinence.
Look I am bored stupid by this discussion so I will summarize it and leave it up to you.
1. The cosmological argument is reasonable according to the common language use of reasonable (it is absurd when qualifications like that are necessary)
Yeah, its not- or if it is, our common standard for what is reasonable has become a total joke, if it lets
invalid arguments somehow count as "reasonable".
and has been acknowledged as such for thousands of years, and still is.
Well no, not really- or at least is only "acknowledged as such" by a handful of apologists and theologians. But what people have acknowledged for thousands of years is not relevant to
what is the case- that would be an
argumentum ad popularum, and we both know you don't give fallacious arguments, so that can't be what you're trying to say, right?
2. It not meet some arbitrary criteria used in technical academia but that has little to do with it's reasonability.
An invalid deductive argument cannot be reasonable, so this objection has no teeth, as we've pointed out several times now.
3. Craig and Plantinga among others say the argument is reasonable (and technically valid)
Actually, not that its relevant, but I seem to recall Plantinga saying that he doesn't think the cosmological argument is sound, which is why he endorses a modal ontological argument for the existence of God and his foundationalist epistemology. Given the latter, Plantinga has no use or need for arguments for the existence of God since for him, belief in God constitutes epistemic bedrock. But this is merely a footnote, and I could be remembering incorrectly.
and you say (among others) it is not. I do not care. There is no way to who is right about either it's reasonability or the standard of logical validity. It simply exists in the minds of men.
4. That is a wash out and only leaves us with common sense. I claim anyone not prejudiced would conclude the argument is reasonable if not conclusive.
5. In all sincerity and honesty I have never seen anyone as aware of the technical aspects of philosophy as Craig. Right or wrong (and there is no objective standard) I have never seen his equal for pure knowledge. He is like a robot. The fact that even professionals as candid and technical as he, Aquinas, Plantinga, etc... and the fact the argument has no flaws I honestly can find personally (beyond the fact it is not a certainty), is more than enough for me to know claims of it's actual (objective) invalidity are flawed in principle.
I claim the client is guilty and obviously so whether you have a valid objection or not and am so bored as to no longer care about the technical validity of the objection.
Yeah, try as you might, validity is a crucial property of ANY good/compelling/reasonable deductive argument. And the cosmological argument
is not valid. We could grant the premises, and it would still not follow that God exists/created the universe/was the first cause/etc. This makes it a garbage argument, which is one reason why it is only of scholarly interest in the philosophy of religion- it is a
relic of a bygone age, an example of reasoning gone amok that we can learn from. Again, this isn't especially relevant to the question at hand, but it seems to me that Craig is the only contemporary thinker of ANY distinction whatsoever who endorses the cosmological argument, and that's not a good sign since Craig is considered a pariah, in part for that very reason, in most academic circles.
