The observer in cosmology, classical and quantum
This talk will review, from a philosopher's perspective, how our being observers affects the scope and content of our knowledge especially in cosmology: both classical and quantum. I will proceed in three stages. First, I consider the topic without regard to physics, whether classical or quantum. Then I consider the situation in classical physics, and finally I consider quantum physics. Being a philosophical realist, I will be optimistic that we can get (or already do have!) objective knowledge. But I will emphasise open issues: especially about the nature of possibility and about the prospects for an Everettian interpretation of quantum theories.
