Vern’s Volvo is the car that he has been driving for over 20 years, not the heap of parts in the back of Grace’s Garage. Just because all of the parts of Vern’s Volvo have been replaced, doesn’t mean that that the car is no longer his. His Volvo is the car that he owns and drives everyday--regardless of whether the parts are new or old. The parts in the heap are simply parts…only when they are put together do they become a car. This supports the theory that the whole is greater than the sum of its parts. Without those parts being in the form of a car, the parts mean nothing to Vern. If you showed him all of the parts in a heap, he would not be able to identify that they were the parts that made up his old car unless someone was to tell him. I guess what I’m trying to say is that he would have absolutely no emotional attachment to them in the form of a heap. If Grace were to use those parts to recreate the Volvo exactly, Vern would probably have an emotional connection to it; however it still would not be his car. It would only be Vern’s car if he bought back from Grace; therefore giving him ownership rights… but then Vern would have two Volvos: one with old parts and one with new- my guess is that he would want to have the new Volvo.
I don’t think Vern would actually think that because he was replacing the parts of his Volvo, it would no longer be his Volvo. Take your home for example; things break in your house all the time (a window, a door, a refrigerator…etc.) and we are constantly taking out and replacing things in our house. It doesn’t mean that our house is no longer our house. If we were to restore our house to exactly the way it was when we first had it (like Grace putting back the Volvo together) it would just be our house in a former state…not what is known as our current house. I know it is not exactly the same, but it proves my point that it matters what is currently ours not what once was. As I have said, Vern’s Volvo is the Volvo he currently drives everyday…not a heap of parts that once made up his Volvo.
