“Philosophers ponder the meaning of life. At least, that is the stereotype. … In fact, professional philosophers rarely ask the question and, when they do, they often dismiss it as nonsense. … If they go on to talk about meaning in life, they have in mind the meaning of individual lives, the question of whether this life or that life is meaningful for the person who is living it. But the meaning of life is not an individual possession. If life has meaning, it has a meaning that applies to us all.”
