Thanks Little Nemo.
What I (think I) mean is that the assembled components of a boat only have some kind of ‘original boaty-ness’ because we recognise their arrangement as a boat. The concept of it being the original boat, or not, is not a property of the boat itself, or its components, it’s a label we imagine onto it, or not.
I was going to go on to try to explain how emergent phenomena (such as personalities of people) are different from this, but I can’t think of a reason why they should be.
Our concept of ‘original’ is really circumstantial, but because it happens to be practically difficult to duplicate people, we’ve treated the concept as if it’s transcendental.
