But the soul can exist, function, desire, worship, feel pain, inhabit places without the body?
I'm not talking about AI, but about a potential future step. Perhaps man could create a real intelligence...if a soul is a body and breath of life, just like animals have (even if not in the image of God), might we create a creature that can think and feel and react with thought, and even be able to choose right vs wrong? And if so, wouldn't it be a soul, made in our image?
I'm going to take a second bite at the apple here.
The ancients including Aristotle and Aquinas assigned souls to animals and plants. One of the reasons the problem of identity is so serious is because of the unsubstitutably of humans. There isn't really a problem of identity with animals and plants since they are all genuinely substitutable or "fungible", like how gold is fungible, one piece of pure gold is as good as the next, as long as they're the same level of purity. There's no soul needed because there's no hard problem of identity that the soul needs to solve, with animals, plants (etc., including microbes for example), or with computers. There's no soul (in plants, animals, and gold) because the ontological force from us all being unsubstitutable demands that our souls are real, there is no force from those other things, because there is substitutability, because there is no ontological requirement of identity. iow that souls are confined to only human beings is straight from reason alone.
The difference between us and the Hindus who came to the same logical conclusion (even though they failed to understand how the soul is antithetical to the caste system) is that we believe our souls are intimately united with our bodies, so much so that the ability to know a person's body is insightful into knowing their soul, and we see this especially played out in our courts of law, when we sentence with justification, some people to grave penalties for what their body did. We were able to find that beyond a reasonable doubt, that convict's soul was also 100% in on it, it wasn't just their body.
And so I find the image of God in us is intimately related to our unsubstitutability–meaning that we must have been created this way (with a soul), yes, but also, in some other way then, we must evoke God in who we are (we are unsubstitutable because we are each ethically independent) and as far as I'm concerned, it's the difference between being able to choose an ethic, and not being able to make that choice, that makes us human, unsubstitutable, and made in God's image.
So if our ethical independence is the image of God in us (and is our soul), I think it's highly plausible God has the choice of ethic as well. And an "ethic" btw, under my lexical stance, is a whole moral theory, it's not partial at all, and there always needs to be a justification for whatever is done, under a particular ethic. (Theodicy btw also, is kind of trying to diagnose the ethic God chooses. From reason, from Scripture, etc. What is God's ethic? We know that God's ethic has generated the Scripture, that's 100% fact. (I am NOT suggesting here, for clarity that I think God's ethic is the Logos or the Holy Spirit.)
And the reason we want to know God's ethic, is so that we can choose the same ethic God chooses. It's not mere scholarship or academia, the intent here is to make a change.
