Good point. Is there a measure of the amount of post-Matrix penetration of the concept of humanity as a consciousness that is distinct from the body? It's highly suggested in the Legion segment of ME3.
How is Western pop culture on this? It's a fairly common conceit in scifi anime.
It's an old enough concept that we're ready for scifi writers to go back the other way and link personality to the body again.
It's hardly a concept that's specific to sci-fi. It's been a formal part of Western philosophical thought since at least Descartes, and of Christian theology since at least Thomas Aquinas. And given how much of Aquinas' philosophy is based on Aristotle, well, you do the math.
