I have some ideas that are still congealing in my mind. I am thinking about a certain ontological problem. Say you have a thing that is composed of a bunch of parts, like a car. Say you replace a wheel. The car is still the same car. Say you replace a couple more parts. The car is still a car. But after you replace enough parts, the car is no longer the same car that we started with. But when does this change happen.
I am pretty sure this is a classic ontological problem. If anyone knows the answer, chime in!
