In Classical Philosophy, there is the idea of the Anima Mundi or World Soul.
The Latin word anima is feminine.
The part of the world where her soul resides, in particular, is in Italy, where one of her sons - Leonardo - magically managed to capture her face.
"There really is only one world soul,
which I for preference call my soul..."
-Wittgenstein, Notebooks 1914-1916
(Wittgenstein uses the terms soul, self, subject, and I interchangeably)
Multiple souls may exist, each unique; however they do not have separate owners. What Wittgenstein was suggesting is that it is the notion of ownership which creates the illusion of a multiplicity of egos.
