"Therefore it is plain that no particular thing can be made by a machine at all; neither an atom, or matter, which is the only identity of matter; nor the soul, which is the only identity of a person (and this applies also to every other animal or vegetable, as every thing, if it feels, must, it appears, have an identical self or soul, similar to that of any other being). No feeling can, it appears, be without reference to some self or soul)"
