26 The truth comes initially to the human being as a question: Does life have a meaning? Where is it going? At first sight, personal existence may seem completely meaningless. It is not necessary to turn to the philosophers of the absurd or to the provocative questioning found in the Book of Job in order to have doubts about life's meaning. The daily experience of suffering—in one's own life and in the lives of others—and the array of facts which seem inexplicable to reason are enough to ensure that a question as dramatic as the question of meaning cannot be evaded. Moreover, the first absolutely certain truth of our life, beyond the fact that we exist, is the inevitability of our death. Given this unsettling fact, the search for a full answer is inescapable. Each of us has both the desire and the duty to know the truth of our own destiny. We want to know if death will be the definitive end of our life or if there is something beyond—if it is possible to hope for an after-life or not. It is not insignificant that the death of Socrates gave philosophy one of its decisive orientations, no less decisive now than it was more than two thousand years ago. It is not by chance, then, that faced with the fact of death philosophers have again and again posed this question, together with the question of the meaning of life and immortality.
