But I assume you would say that the matter in your vicinity is subject to natural laws, but that God can break those laws at any time. Sounds like two very different kinds of things -- the stuff that's subject to natural law (everything except God) and the stuff that's not (God) -- as opposed one kind of thing (everything, all of which is subject to natural laws).
But even in nature there are things that certain laws don't apply to. There are particles that the electromagnetic force applies to, and particles that it doesn't affect. Particles that the strong force applies to, and particles that it doesn't affect.
Or, to use an analogy to Orbiter, the laws of physics that apply within the sim do not apply outside of it (very nearly, but Newtonian Physics is only an approximation, and even if Orbiter did simulate the laws of physics perfectly, it would not be Orbiter code that made the real Moon orbit the real Earth.) The laws of physics outside of Orbiter do not apply within the sim. They *do* however, determine how the computer the sim is being run on can be built, and how the hardware is built puts constraints on how the software must be put together. Reality inside the sim is not separate from reality outside the sim, it is a subset of reality outside the sim. And while certain laws of physics determine *for the most part* how things happen in the sim, there are "backdoor laws of physics" that determine how the sim interacts with the outside, the spacecraft control interface is one, the scenario editor is another.
Likewise, physical reality is not separate from "the supernatural," but rather a subset of it. And while the laws of physics determine *for the most part* what happens in physical reality, there are backdoor laws. To go back to the computer analogy, God can be considered a user of physical reality with admin priveleges. We can be considered users who each have direct control over one object in the sim.
In my experience, the opposition of most religious people to human augmentation is rooted in religious belief or sentiment -- "This is how God made us, this is how we're supposed to be."
Many religious people will object to various technologies by saying that pursuing those technologies is "playing God." I generally answer that sentiment with this scripture: "It is the glory of God to conceal a matter; to search out a matter is the glory of kings." (Proverbs 25:2, NIV).
Nevertheless, I do have some objections to human augmentation. With certain things it's more of a "Good luck" thing (ie, you can try human level AI and uploading if you want, but I don't think you'll manage it), but with other things it's more of a human rights thing. For instance, I don't think that germline genetic engineering of human beings is wrong in itself, but I do think that it runs into serious issues with things like experimenting on a subject that cannot give consent. If germline engineering is ever carried out on humans, I think it's likely that within a generation you'll get lawsuits from engineered individuals born with debilitating birth defects from botched engineering. Once it's actually carried out, I think a big portion of objection to such engineering will come from engineered individuals themselves. But in a perfect world, I don't think germline engineering of humans would be a bad or ungodly thing. The process just runs into problems with the fact that this isn't a perfect world, and that while progress is good, we can't run roughshod over other obligations to accomplish it.
I have encountered a very few religious people who will say that the capacity to transcend the current state of human nature is within the scope of the endowment supplied by God,therefore, it's OK.
Actually, a big part of the Christian worldview is that Adam and Eve sold all of our souls to the devil and got us into the current state of human nature, and that what Jesus did for us was to buy back our souls (or at least the souls of those willing to have their souls bought back) and make it possible to transcend our current state (our current state being less than what God intended). Of course, this is talking from the spiritual and not the physical perspective, but from the physical perspective technology and (if possible) transcendence are double edged swords: They make good people able to do more good and bad people able to do more evil.
But the fact is that most religious authority figures and scholars firmly oppose human augmentation.
To at least some degree, yes. I think you'll find that more than you think think like me (but probably not all). I have my doubts about the possibility of certain types of augmentation and I think other types can go horribly wrong, but insofar as things are possible and you can avoid abuses, I'm all for it, as long as you don't start thinking that it will create any more of a utopia than any other technology, or that augmenting yourself somehow makes you God.
