alt Hacker NewsI think it goes the opposite way, starting with a soul and arriving at biological exceptionalism: You start by saying "I have a soul / spirit". Then you extrapolate "things like me probably have a soul / spirit". But since there is no theory of souls, the extrapolation is not based on principles but rather on vibes and guesswork, ending up somewhere like "there must be something weird going on with neurons that somehow create a soul, connect with an existing one or something like that.. maybe.."
Which is an interesting argument because: do neurons somehow create a soul (as you mentioned), or are do neurons somehow attract souls, or do souls choose what to inhabit. In the first case it posits that a “soul” is purely a function of biology. In the others that there’s some sort of inextricable link between the two (which in the absence of any theory of soul or how these are linked to biology, seems rather far fetched, unless of course souls could choose to inhabit anything with sufficient degrees of freedom: a brain, a mega computer, a planet, a galaxy)
