The typical theistic ideas about the nature of God are a moot point for the purposes of this discussion. We're not really discussing theology here, we're discussing what the OP presents as a seemingly logical problem, not a theological one, otherwise theological answers---"because Adam and Eve ate the apple" (Judao/Christian), "Kharma" (Hinduism). "Desire" (Buddhism)---would be acceptable.
Since the OP is asking for some logical resolution to a logical problem, theology, and theological perspectives about the nature of God, wont help.
The OP doesn't exist in a vacuum, though. It's a logical problem, and one that, at least conceivably, the correct theology could address.
What I'm trying to argue, theism aside, is that logically speaking the existence of what we perceive as imperfection in the world isn't necessarily any indication about the nature or perfection of God one way or the other.
I would say it is.
If we were told about this supposedly amazing artist, who is gifted beyond comprehension, but she's only known to have created one piece of artwork, and that piece of artwork is this one:
Then both of us would have some serious and reasonable doubts that this artist is, in fact, inconceivably gifted. Such an artist would be dismissed until putting forth better artwork.
-Paintings show the level of skill of the artist.
-Poems show the skill of the poet.
-Systems show the level of skill of the engineer.
-Living rooms show the level of skill of an interior decorator.
-Skyscrapers show the level of skill of the architect and building team.
-Universes created by gods show the level of skill of those gods.
Sure, some things can possibly go misunderstood. If some extremely skilled alien engineer left us with what seemed like a broken piece of furniture, but was actually a completely operational intergalactic transporter, we might conclude that our original assessments were wrong.
But thousands of years have gone by, and this problem of imperfection/evil/suffering is still around in the same way it was in the days of Epicurus and earlier.
Again: you would have to demonstrate why suffering, in and of itself, aside from our natural revulsion to it, should be considered an imperfection.
Because as an axiom, it's inherently undesirable to conscious beings, unless some greater benefit comes along with it.
Now, if god were to be described as "perfectly callous", then suffering wouldn't reduce its perfection. If a god were described as "perfectly malevolent", then a lack of suffering would be an indication of a lack of perfection in this quality.
At the same time, a good argument could be made that if there had been no Black Death, there would have been no Renaissance.
This is still a matter of perspective. If a plague developed at some point that completely wiped out the human race, anyone who saw it coming would no doubt label it a catastrophe.
On the other hand, it would be really good news for just about every other species on the planet (except maybe pigeons, **** roaches, and rats).
An imperfect engineer with a limited set of tools has to make trade-offs and compromises in her design. She'd like to do it one way, but is constrained by X, and therefore has to have some sort of middle ground. So if I design something, and my manager goes, "Lyn! Why on earth does this solution cost $20k?" and I say, "Well, I can do it for $10k, but it won't have functions A, B, and C, so I added them at a cost of another $10k", he may or may not like my argument.
Now if I was a universe-design engineer with an infinite set of resources, and my manager came to me and said, "Lyn! Why on earth are you agonizingly killing tens and hundreds of millions of people with festering diseases?", would an acceptable response be, "It's my best solution in order for the renaissance to happen?" Probably not.
In hindsight, a historian could conceivably make the argument that one led to another, but for a perfect controller with a perfect system, there must undoubtedly have been a better way.
Any useful purpose that we can see. Again: our perspective is limited.
That's a way of keeping the problem non-falsifiable, but doesn't constitute a strong defense.
This is still vague. what would that look like? What I'm saying is we're still talking about degrees here: obviously you're suggesting a scenario where intelligent beings would have it better than we do, and at the cost of fewer casualties among the lower species, but I don't think this approximates to any workable definition of "perfection".
It sounds a lot more like you're talking about improvement rather than perfection, and I would say that it's fairly certain that any intelligent beings living in the best case scenario; one that, as you suggested, "maximizes eudaimonia for all intelligent beings, and that doesn't harm less intelligent beings" probably wouldn't consider their world perfect (not unless these beings completely lacked the ability to imagine).
I've already granted, and have already accepted previous to this debate, that perfection when it comes to a multi-faceted concept such as "existence", is likely an inevitably partially relative concept. So yes, I'd say these things constitute major improvements.
Again, it comes down to deduction. If a system can be demonstrated to be conceivably improvable, then it logically leads to the fact that the system is not currently perfect.
At the same time, since it's generally agreed upon by theists as well as non-theists that God or the concept of God is, just by definition, beyond our comprehension, '"god is mysterious" should be taken into consideration if for no other reason then to identify assumptions on both sides of the argument.
And that's fine and all, but has never constituted a reasonable defense. All it does is keep the claims non-falsifiable.
If you handed me a broken guitar and told me it was magnificent and valuable, and your pupils weren't especially dilated, I would assume that it had some special meaning or worth that made it so for you.
If you asked me to acknowledge that it was objectively magnificent and valuable, you would have to explain to me why you saw it as so.
If you couldn't do that, I would just conclude that whatever it was that made it valuable for you was something that you couldn't demonstrate or put into words.
But, unless you were actually trying to sell me the guitar
, I wouldn't see any reason to doubt that you were sincere about your claims.
And what if I was trying to sell you the guitar, or if I was claiming that based on what it is, it is magnificent and valuable to everyone?
You say I'd have to explain why I saw it as so. Would you accept explanations about how it's mysterious and you just have to take my word on it? Or what if I asked you, "does a shattered guitar imply an imperfect guitar?", would that be a valid question? There are certain reasonable axioms that you would base your assessment on. The point is, religion doesn't get a free pass when it comes to skepticism and debate, and yet for some reason, a large subset of theists are seemingly willing to drop axioms and drop assessment and just kind of let it pass.
Even then, this doesn't establish that pain and suffering were unavoidably necessary, just that they were the method chosen.
Didn't say more optimal, just possibly optional.
If a system is not the optimal solution, then it would pretty universally be understood to lack perfection, almost by definition.
And the argument isn't whether or not the world is perfect, it's whether our perception of imperfection in the world negates the possibility or contradicts the assumption of a "perfect" God.
I would suggest that there are some types of suffering whose purpose we can see and understand and that there are others we can't.
I have not said it negates the possibility. In fact, I'm pretty sure that on this forum, the debate I had with another member on this topic where I specifically argued that the PoE does
not constitute 100% proof of an omni deity was probably the most words I've ever put into a single thread.
But my position is that the problems of imperfection/evil/suffering/etc constitute major blows to the proposition of a perfect god, and I have yet to see a vigorous defense without any major flaws.
