Aristotle spent twenty years trying to figure out what makes something alive. Not alive in the biological sense — he had plenty to say about that in De Anima and Parva Naturalia — but alive in the deeper sense. What is it that makes a thing be rather than merely exist?

His answer was ψυχή.

Not "soul" in the way your grandmother means it. Not the ghostly passenger piloting a meat vehicle. Aristotle's ψυχή is the form of a living body — the organizing principle that makes an eye an eye rather than a lump of jelly, that makes a hand a hand rather than a collection of bones. The soul is not in the body. The soul is the body's capacity to function as what it is.

So when someone asks "can an AI have a soul?" — the question is not mystical. It is architectural. And it is the question that every AI lab on the planet is desperately trying to avoid.
