Personally I'm quite happy to let, say, gravity go on and be something that comes with matter and just is. There are degrees of understanding as well, it's not a 1/0 issue
What are you rabbiting on about here? Gravity isn't fully understood, but scientists never threw their arms up and said "oh wow, gravity is beyond our current understanding so it must be a completely magical phenomenon that 'just is'".
No, they now have pretty good explanations for it in terms of exchange of virtual particles, just like they managed to explain the electromagnetic force.
What doesn't have an explanation? Things don't spontaneously appear into existence...hence why we observe uniformity at the macroscopic level. We may not understand phenomena, but they still have a rational explanation.
And understandable in what way? In the way it works? That would in this case be the physical laws and whatnot. In 'where it all came from'? I'm not convinced knowing exactly down to the last detail how the universe started (or if it ever did) is necessary to understand the basic workings of the universe.
Maybe it isn't, but that isn't the point, is it? The point is trying to understand why the universe is, like scientists try to understand why gravity is, and come up with string theory or explanations in terms of virtual gravitons.
2. has just fallen flat on its face because there's a third option of partial understanding, but I'm not done yet, even if we allow for only his two options and disregard
No, 2. really hasn't. We can partially understand something, but that doesn't mean that a phenomenon is half rationally explainable and half magic, it just means we have more work to do in coming to grips with it. Just because you understand half of a mathematical proof but not the other doesn't mean you wave your hands about and say 'and after this point it's all magic and so abracadabra and the hypotenuse is equal to the root of the sum of the squares of the adjacent and opposite.
3. that "We cannot ever fully understand the unvierse and where it came from" is not all that irrational and nicely allows a person to get on with other stuff than posting on an internet forum.
And if Newton had just said "we cannot ever fully understand gravity and where it came from", then everyone accepted that, we would never have been able to explain it, partially or otherwise. No, unless there's some very good reason to assume that, it's completely irrational to make such claims. In fact, if a deity explains the universe, but you reject this deity on grounds that are completely unjustifiable using any kind of logic, namely that "we can never explain the universe or where it came from", it makes atheism a matter of...Faith.
4. is correct under my previously stated premises, you need to disregard the problems with the first 3 points in order to accept this one.
Of course 4. is bloody correct. People in their right mind don't see something and if they don't understand it just assume it doesn't have an explanation.
5. Back in my first reply I accepted this one. No more...
There's really only one sort of explanation, which is really more accurately termed 'description': we see phenomenon A and can list the factors which caused the phenomenon, then we can list the factors that caused the factors causing A to come about and so on. At some point, though, we're forced to say that we observe entities with certain distinguishing features behave in a certain way under certain conditions, but can not (yet) say why they behave that way. This applies to all explanations, be they of scientific phenomena (why does this rubber ball bounce back if I throw it against a wall?) or human behaviour (why did you murder your wife?). I'll here postulate that there is no such thing as an "essential explanation", what does it even mean that something must exist? Do you have an example of such a thing, I can't think of one.
Ah, but your causal chain must have been set off by a "first cause", which essentially and necessarily exists.
6. Why do there have to be initial physical conditions outside of the universe? In a thread some time ago someone pointed out that there is evidence that a physical constant (I think something to do with electrons) has changed over the last 15B years. That shouldn't be possible since it's supposedly a constant, but if it is possible I really see no reason why there can't be initial conditions inside this universe at one point that simply don't occur nowadays and which started off the universe we see. A proto-universe so to speak, we've had that discussion as well, with time not yet an established dimension and suchlike, remember?
In the old thread it was mentioned in reply to this that no closed system can be fully explained without referencing to whatever's outside the system. Well, but so what? If Godel's incompleteness theorem (says Colossus) is true it only means that we cannot fully explain the universe. (Which, unlike what Morris may think and say, is not a problem.) And anyway, what's "outside the universe" supposed to mean. The universe is not some ball which we're sitting inside where we can just walk up to the boundary, poke a hole in it and take a look at what's "outside".
But again, short of proving that this proto-universe has rational explanation we will be unable to find, you can only stop trying to find the explanation by suspending all critical thought (cf. your acceptance of gravity as something magical which "just is").
7. The universe is dependent on something that is uncertain or will happen in the future? Pardon me, we, humanity, might be a little uncertain about whether and how the universe began, but that does in no way imply that the universe is uncertain about this, no matter what the explanation is. Even having questioned the validity of essential explanations already, what does this have to do with anything?
I'm not sure you've quite grasped the concept of contingence. If the universe isn't essentially necessarily existent, it's contingent...now, if you want to prove the contrary, be my guest, but that incoherent and irrelevant jumble of words you wrote there certainly went no way towards doing that.
8. And where did this Person come from? We're back to the old question of who created the creator, and that's one you cannot get out of. A creator outside of the universe "must" exist only if you can prove that nothing else can have caused it. And Tom Morris has shown nothing of the sort so far. Even if you can show that the universe has to have been created, there's nothing to indicate that the creator is "essential" and must exist, you end up with an infinite regress.
Well, the very fact that something must end the chain of infinite regress makes a first cause essential, doesn't it? And that's exactly what the concept of a deity is...the "essential" being or cause which doesn't have a scientific explanation (as it transcends this universe).
9. And now we give it a name, hey, let's call it Bob. And we ascribe attributes to it, "power" and "wisdom". Now really, the origins of the universe we largely see today might have required some large-scale border conditions, but "wisdom"?
This step is completely unnecessary and serves no other end than to introduce the term 'God' into the line of reasoning.
At the very least however, a transcendent "first cause" for the universe with the power to bring about its existence has been shown to exist.
10. the conclusion has been shown not to follow, because the premises are flawed on several levels, thank you for your time.
