At what precise moment does an individual stop being who he thinks he is? Cut off my arm. I say, "Me and my arm." You cut off my other arm. I say, "Me and my two arms." You take out my stomach, my kidneys, assuming that were possible... And I say, "Me and my intestines." And now, if you cut off my head... would I say, "Me and my head" or "Me and my body"? What right has my head to call itself me? What right?
