Actually soul is Christian concept that inherits it from greeks that applies to living humans spirits only.

We can talk about "anima", in latin, the same inside "animal" or "animation" to apply it to a wider concept of living beings.

We can go further in time to the greek concept "daimon", devils, allude to supernatural powers or spirits to start applying it to things.

Then we could apply De Boers sociopaths concept that goes back to using the Christian concept to rocks again.

The only "soul" those rocks have is the one of the millions of African people that died in wars, the women that were raped and the kids that were traumatised being forced to kill their family members so a woman can look at beautiful iridescence in her finger.
