They appeared to have souls, or at least higher intelligence, but they were given the replication of such virtues by their creators, in their own image. Therefore, their 'souls' were those of the humans who had made them, or rather what the humans thought souls should be like, since I don't know anyone who has actually yet discovered their own soul. Or even someone else's.
What is a soul? How shall we know it? What does it mean to be soulful? Or soulless? Most people say someone is soulless if they appear uncaring, insensitive, or downright cruel. Yet right in the heart of the Church, the very home of Souls with a capital 'S', one has found abhorrent cruelties and a singular lack of care (I'm thinking of the treatment of unwed mothers and their children, let alone the Inquisition and witch-burnings). So where were the souls of the holy then?
Damn, it's much too late/early to be mulling the existence of the soul. I don't see the point of having one, to be honest. I'd rather the physical body here on Earth behaved as kindly as it could to its brother and sister humans, and bugger what happens once we're bones. Relying on our soul resting in Paradise doesn't seem to encourage particularly pleasant behaviour here on Earth.
