Some other poster gave you three different, common answers. For me personally it's God. But you could just as easily say natural law/natural order and IMO that's basically interchangeable with the concept of God and the concept of right/wrong anyways.
Okay, good. Thank you. I've never said right and wrong don't exist. I've never said there's no value in human life. I've never said nothing matters and everything is particles. None of those are remotely close to my position.
My position is that the value of human life is not fundamentally tied to the existence of that human life, I think it's tied to something else, and this is the part I'm really interested in exploring. For religious people, I think that "something else" is probably the soul. For non-religious people, I think that "something else" is probably the perceptual human experience. I agree with you that the value can be modified. I agree with you that the value can never be absolute zero. I agree with you, in the case of a serial murderer or something, that the value can even be negative. But if the
something else is not attached to the body, I believe that value is no longer there. It's gone. It's gone to heaven, or hell, or to non-existence, or wherever.
I personally, do not see moral value in a braindead baby. The value I put on human life was there, but it stopped applying when the baby's brain functions ceased. That baby, to me, is a dead baby. Yes, the thought of a pedophile fucking it still morally revolts me, but I don't think that this is the "delusion dropping" and forcing me to see a human life that I morally value. Looking at a realistically drawn depiction of a pedophile fucking a baby would equally revolt me. I do not believe that my revulsion is at all relevant to the moral consideration I give that braindead baby. I think the thought of pedophile fucking a baby is just a really, really nasty thought to have in anyone's mind, and we're all going to be grossed out by it.
You disagree, and do give a braindead baby moral consideration. That's fine, if you're religious and you believe in the existence of a soul, I would fully expect you to value that baby because the soul is presumably still there, and God's plan might not be fully realised. My question would be, if the rapture happened, if the skies opened, and you watched a sparkling translucent baby soul float out of the baby, and wave to you, and float away to heaven, and people to the left and right of you started collapsing and you could see their souls float off to heaven, and maybe you were a bit of a dick and you have to stay behind, but you knew without a shadow of a doubt that this baby's soul had left the body and gone to heaven, would you still see an immutable moral value inherent to this baby's living body, brainless and breathing on a ventilator?
