For a side of Philip K Dick most don’t know, find his short story “The Pre-Persons”. That one will never ever be a movie.
I’ve read it. Although I know he was intentionally “over the top” to make a point, it just struck me as absurd. For those who haven’t read it, the whole thing revolves around abortion being legal until the soul enters the body which is when the mind grasps mathematical concepts beyond simple arithmetic. It should also be noted that it was written as he was experiencing a severe mental breakdown.
