I've never read this guy's writing before but in this article I think he is way over-intellectualizing things. Meaning is whatever you want it to be. Some people find meaning in easing the suffering of others. Some people find meaning in raising children who will raise children, etc. even if in the fullness of time they will all cease to exist. Some people find meaning in really good sushi. It doesn't need to be any…
That is basically the post-modern absurdist position on the meaning of life. Most people still believe in an external source of meaning (religion) that exists regardless of your personal opinion.
