How evolutionary biology makes everyone an existentialist
Ethics cannot be based on human nature because, as evolutionary biology tells us, there is no such thing. Questions about what matters, and why, and what exists in the world, are quintessentially philosophical. The answers to many of these questions are informed by how we conceive of ourselves. How has what is often described as the ‘Copernican revolution’ effected by Charles Darwin changed our self-conception? One particularly surprising feature of evolutionary biology is that it lends significant support to existentialism.
