- No one is saved who does not have a love for God in this life.
- If materialism is true, early human embryos do not have a love for God.
- At least some, perhaps all, people who die as early embryos are saved.
- So, materialism is false.
One might even try to run the argument with young infants instead of embryos. But there, I think, the argument could run into difficulty. For it may be that a young infant's brain hardware is sufficiently developed to love God, but simply does not have the software for it. And God could miraculously give the infant the software. I suppose the Christian materialist could think that God could miraculously join the embryo with a brain, perhaps a brain in another dimension. But it is not clear that that both such an embryo would then be one of us humans and that brain would be its brain.
