The woe of mortality makes humans God-like. It is because we know that we must die that we are so busy making life. It is because we are aware of mortality that we preserve the past and create the future. Mortality is ours without asking--but immortality is something we must build ourselves. Immortality is not a mere absence of death; it is defiance and denial of death. It is 'meaningful' only because there is death, that implacable reality which is to be defied.
