Yes, this is the Thomistic view on soul. Is based on Aristotle indeed.
View? You said theory. Which is it? I ask because "theory" is science. It is supported by evidence, experiment, observation and experiment. You just tried to support what you said with evidence. Posovitism? Are you doing exactly what you accuse other of?
Oh you! You're such a hypocrite!
I didn't said that. I said animals, humanoids and anatomically modern humans can live without the immortal soul (Psyche) but not without the mortal souls (vegetative and sensitive or Anima).
No, you said god gave some humanoid animals souls, that made those specific animals human, who then had sex with the non-ensouled animals. That's a clear case of bestiality.
Why does your religion promote bestiality?
So, anyway, you STILL have't shown us how your definition of posovitism is correct. Why are you so afraid to do that? Seriously, if you were in fact correct, it would take... two, maybe three sentences? Why won't you do it?
