 I guess some rather extreme liberals or materialists, but it's not a view held by me. I don't think that it's all just undifferentiated flesh. I think that things like organs have both form and matter. So there's the matter, there's the flesh, there's the stuff, but then there's the form, which tells you about what that thing is. And so my liver might look a lot like your liver, but they're different livers.
