At this point I think we're both a little confused.
In an attempt to clarify my understanding I'm going to ask what may seem like a nonsensical question. I'm hoping that it'll make sense, but there's a good chance that it won't.
You stated:
How do you differentiate an "endemic intent" from "mindless determinism"? The former would seem to imply a conscious agent, but I see no reason to assume the existence of a conscious agent when mindless determinism may well produce the exact same results.
Or perhaps I'm just confused by exactly what you mean by 'intent'. After all, even mindless determinism would seem to have a teleological aspect to it.
"Teleological", at least to my mind, is another one of the necessarily human considerations of a thing. That is to say, we describe things according to their end [result]; that may help us understand the thing being considered, but it does not define the thing. Or at least, it is does not accurately nor completely explain the thing. It is just part of our way of thinking —our language.
So, if "mindless determinism" has a teleological aspect to it, that fact does not imply purpose, and
there is the difference. You seem (to me) to be saying that 'mindless determinism' has the same [apparent] end result as 'endemic intent'. And yes, as far as empirical science can tell, this is true. But it doesn't describe how it is possible for 'mindless determinism' to do anything, nevermind to actually begin any new thing. It only assumes that 'mindless determinism' can cause things.
Science has a way of finding a cause by way of empirical effect(s). That, really, is all it does. (And it is easy to get confused as to whether we are looking for God as a teleological effect of our investigating, instead of as the cause of the effects we are trying to consider. Or at least, it is easy for me to get confused and lose track of the logical trail I was trying to present —just ask
@Hans Blaster !) Science's reasoning is drawn on the effects, but Theism sees that God, as the uncaused first cause, is the only brute fact; that God is the source, the default, and that a good definition of God is necessary for seeing the effects clearly. Science does not oppose this, but scientists sometimes do, claiming it is begging the question to begin with God. But consider an argument I got into with a skeptic on another site.
Skeptic: "Just one look at the Bible story about the serpent in the garden, or the donkey speaking, tells you the book is worth about the same as a fairy tale."
Me: "Well, IF Omnipotent God exists, then that whole statement falls apart."
Skeptic: "Well, you've got a long way to go to show that God exists."
Me: "Tell me about it! You won't accept the short version as valid: That God is the only valid explanation for existence itself."
Skeptic: "Well? So start showing it!"
Me: I just did, sort of. If you begin with God, the whole business falls into place, including every effect's cause and every cause's effect. Empiricism can't do that —at least, not yet. Begin with God, and the empirical makes sense. Begin with strict empiricism, and you can fool yourself, thinking that existence doesn't demand a cause.
Skeptic: Rolls eyes.
