^No, it is not a contradiction. We don't fully understand the nature of the immune system, but we safely understand it's roots are biological. We don't fully know the nature of type 1 diabetes, but we know its roots are in an inflammatory immune response. We don't understand the exact nature of consciousness, but we know
its roots are in the brain. As I said before, just because we don't know everything
about something doesn't mean we discard what we do know.
