Moral value and what it tells you about you. "Not because of the shape or size or colour or location of your physical body. For if your body was a different shape, or size, or colour, or location, this would not affect your moral value. Plus I myself do not seem to have any of those features, yet I seem morally valuable (it is my body - not me - that seems to have a size, shape, colour and location)."
Each body is valuable and unique
"It also seems obvious that when a mind is not present in a body, the body has no moral value and its destruction is not morally bad. For instance, a mindless foetus or a corpse both seem to be things whose destruction is not morally bad (those who think it is always bad to destroy a foetus, think a mind is always present from conception - which as well as being implausible, just underlines that it is the presence of a mind, not the presence of this or that physical feature, that is doing the moral work)."
Well abortion is immoral but that's a different question. The issue is live humans and what makes them valuable
"What about consciousness? I don't think so because a) when I am unconscious I am still morally valuable - it is not morally ok to destroy those who are unconscious, other things being equal and b) many conscious states are morally disvaluable - such as undeserved pain - yet a mind that is in undeserved pain does not thereby come itself to be morally disvaluable. I can have thoroughly bad mental states, yet still be morally valuable. So, if a mind can have moral value despite its conscious states having moral disvalue, then the mind's moral value is not grounded in its mental states."
It's grounded in biology. So you haven't addressed the issue
"It seems, then, that we are morally valuable because we are minds."
Why? All you made where asserions
"And we can also conclude that our minds are not our bodies, because our bodies would not be morally valuable were it not for the fact they have our minds in them."
Statement, not argument
"To put it another way, if you think we are lumps of meat - just lumps of meat that happen to think things - then you have a problem when it comes to explaining our moral value."
Statement, not argument
"You can't say that we are morally valuable because of our conscious states, for they can be thoroughly morally disvaluable, yet we can still be morally valuable despite this."
Who said it was based on conscious states? That is not the issue
"And you can't say that we are morally valuable because we are made of meat, because the meat itself is not morally valuable absent a mind inhabiting it."
Statement, no argument
"Reflection on our moral value seems to reveal something about what we are, then. It reveals that we are not physical bodies, but immaterial objects."
This last sentence should have been the whole thread. You didn't make argument, like I said
