"Consider another analogy. If you are worried about your father’s health, it does not make you less worried about his health if you are told that your mother is entirely healthy. It is obviously good that your mother is healthy. If she were not, you would worry about that too. However, being told that you need not worry about her health does not diminish your worry about his. Similarly, while things would be much worse if our lives lacked any meaning, those who are concerned about the absence of cosmic meaning are not consoled about that by the observation that at least some kinds of terrestrial meaning are attainable. The point can be expressed another way. I may derive some meaning from helping another person, and that person may derive some meaning from helping a third person, but that provides no point to our collective existence. We can still say that human life in general is meaningless sub specie aeternitatis. There would be something circular about arguing that the purpose of humanity’s existence is that individual humans should help one another. Moreover, even if an individual human’s life has some terrestrial meaning (perhaps by helping others), it does not follow that that individual’s life also has cosmic significance."
