You have not convinced me of the cogency of your objections.
For the FTA to have any utility, it needs to have some persuasive power. No belief is held in isolation, and this makes it difficult to judge an argument the same way a non-theist would (even an open-minded agnostic who is open to both God's existence and non-existence). The fact that you bring up intentionality demonstrates that you aren't judging the FTA apart from your related beliefs.
BTW, I haven't mentioned my own position. I call myself an "agnostic deist." This means that I consider it possible that there exists some sort of entity that created the world, but it is also possible that the world is simple a brute fact. My reason for thinking a "deity" is a distinct possibility is the existence of consciousness - which is difficult to account for under materialism. It actually would have bearing on my position if the FTA were at all convincing. I try to look at it as objectively as I can, although I'd never claim I'm better than anyone else at this.
there are definite ends (aka "final states" -- which need not be "final") to which physical processes tend... If we then say that any source of intentionality is, by definition, a mind, then a mind is responsible for the laws of nature
Interesting perspective, but I have two questions about it:
1) How is it not arbitrary to label any state as a "definite end" or "final state", if every state will evolve to another through a potentially infinite future?
2) How would one distinguish a non-intentional state from an intentional one? I ask because your claims seem based on the assumption of intentionality ("knowing" that God did it) rather than demonstrating it.
I agree, that is why there is no scientific support for a multiverse...
There's also no scientific support for intentionality or God. You seem to be doing exactly what I anticipated: only considering metaphysical possibility to admit God into consideration, and refusing to admit it for anything else. This is inconsistent.
Relativist: "if we're including God among the possibilities to consider, we have to consider all metaphysically possible worlds"
No, we don't. We only have to consider actual evidence
Then this removes God from consideration.
Possible worlds talk is just a way of injecting baseless speculation into philosophical discourse.
Possible worlds is just a semantics for discussing modal claims. You are inconsistent in your use of modality. What exactly is the modality you propose to use to "baselessly" (without evidence) propose God as the solution? For God to be the answer, God must be "possible" and possibility entails a modality. You could use epistemic possibility (as far as we know, there might be a God), or conceptual possibility (God is conceivable, and therefore possible), or broadly logical possibility (God's existence entails no broadly logical contradictions). But whatever modality you use, consistency demands using the same modality to consider multiverse. Clearly, God is not physically possible, so you can't use this.
(re: sandstone and snowflakes) The existence of the required elements (H, O, Si) does not require nuclear fusion in stars and so is far less constrained than the existence of life.
Snowflakes depends on a variety of elements, planet formation, atmosphere, liquid water on the planet surface, evaporation, a narrow range of atmospheric and surface temperatures, dust in the atmosphere.
Sandstone also requires a planet with certain minerals present, water flowing - and thus the presence of sufficient water so that it will pool and flow, a narrow range of temperature on the surface, and in the atmosphere. Silicon only exists because very large stars previously existed that could fused it and later when supernova. Water itself is dependent on the production of oxygen by stars as well.
Snowflakes and sandstone are probably more prevalent than life in the universe, but their existence is still dependent on prior conditions - conditions whose probability is indeterminable.
No, again. God is a metaphysical necessity. The only possibility that can be attributed to God is epistemological -- due to ignorance. The evidence for God's existence is all being. If anything is, we can conclude, with metaphysical certainty, that God is.
More correctly: it is epistemically possible that a metaphysically necessary God exists. The only modality in which the possibilities for both God's existence and non-existence can be evaluated is epistemic modality. But a multiverse is also epistemically possible - you admitted this.
While I don't deny the biological importance of DNA, your genetic coding doesn't enter into my judgement that you're human and Fido is a dog.... What does that have to do with anything?
The issue is that "essence" is a concept based on a primitive analysis of human-ness and dog-ness (etc). If everything that makes us human or dog is an accident (as genetics and evolution suggest) then there is no reason to think there IS such a thing.
I don't see that you've shown that there is no basis in reality for saying that a thing is (existence) or what it is (essence).
You're forgetting that my original issue is that the existence of "essence" is an assumption. I didn't claim it was incoherent. Again: every metaphysical theory depends on assumptions. This seems so trivially true, I can't understand why you'd deny it.
I showed that it is not a postulate, but names something found in reality -- i.e., the objective basis of essential definitions -- what it is about concrete individuals that allows us to apply our species concepts to them.
No you didn't! You denied the concept is related to DNA, even though you earlier claimed species entailed essential kinds. That is contradictory. Now you've claimed it's not just a sortal of accidental properties, and made the vague assertion "what is essential to my concept of humans -- a concept that is largely transcultural". What exactly does essence refer to? Identify something about dogs that set them apart as an essential kind from wolves, that is not simply the accident of DNA variation.
Relativist: " Aquinas paradigm also postulates: act, potency, form, substance, and accident."
All of which we find in our experience of reality and its conceptualization.
Seriously, do you not understand that this is a postulated pardigm? It is a way to account for the things that exist. Earlier I referenced Armstrong's ontology. He accounts for existents differently, and it's every bit as complete and coherent. I'm not going to argue that Armstrong's account is true and Aquinas is false, because they both account for everything - they are simply different, unproveable paradigms.
the fact that we have one reality based conceptual space that can be used to analyze reality does not, by any means preclude the possibility of other, equally reality-based, conceptual spaces that can be used to analyze reality. Given that reality is far too complex to be exhausted by the stupid human trick of abstraction, the more ways we think of reality, the more projections we use, the better.
What you call a "conceptual space" is what I'm calling a "paradigm" - but other than this, I agree completely. But there's an important corollary: one can't "prove" any particular "conceptual space" is true. Thomistic metaphysics is popular with theists because it entails a God, but if someone claims this constitutes an objective proof of God's existence, they are ignoring the epistemically contingent nature of the Thomist paradigm.
