The problem with the physical sciences — or with the catchall that Faust called "medicine" — is that when it comes to the difficulties of mortality, scientists are committed to a particular methodology, which necessarily avoids satisfying existential answers. End-of-life issues are subjectively felt; there is a singular quality of experience to each passing life. This is what Heidegger means when he claims that death is a person’s "ownmost possibility." When an old man asks, "What is the meaning of life?" he simultaneously queries the infinitely more particular question: "What is the meaning of my life?" Which is also the question: "What might be the meaning of my death?"
