The essay “Evolution and Existentialism, an Intellectual Odd Couple” by David Barash proceeds from the premise that evolution and existentialism appear to have contradictory answers about the meaning of life, and then attempts to reconcile them. I don’t feel strongly about the conclusion, but I do find the premise to be faulty, for the reason that evolution does not tell us about the meaning of anything. If it does not speak to the question of meaning, then it cannot conflict with any particular framework that does offer meaning.
Why do I say evolution does not speak to meaning? Mainly because I understand meaning to be extrinsic, rather than intrinsic. Evolution describes a sequence of events and a mechanism for how they came about. The accuracy and usefulness of that description can be discussed within the scientific framework. But what it means, if anything, is an entirely independent question, and it can be answered from any number of perspectives.
