Life (at least biological life) is finite, and all people must eventually face death. Despite knowing this, people have a wide range of emotions and reactions to death. Some people embrace it with a sense of honor and dignity. Some fear it, and some refuse to acknowledge that they will ever see death. Does knowing that death is inevitable change how we life? Why does death surprise us?
What about the possibility of the soul? If we have a soul, is it finite like the body? Perhaps, it is not subject to the natural decay of the universe, and perhaps the soul can "live" on after the body has ceased to function. Does this possibility change the way we live? Maybe it is impossible to know for certain, but if it was, would that matter? Would knowing that we will live forever have any effect on how we choose to live today? Would our choices be different? What about our values? Do we even want to live forever, or is ultimate death a welcome relief from the trails and pain of life?
