I am reminded of a piece on the Car Talk radio show a while ago. Someone wrote in about his correspondence with Volvo. He said that he had replaced most of the parts on his car, and wanted Volvo to pay for replacing the few remaining parts in an effort to answer the epistemological question of whether it would still be the same car.
Volvo thanked him for his interest in expanding the bounds of human knowledge, but politely declined to participate in the experiment.
