Despite the general consensus, I disagree with the idea that you can explain consciousness in an entirely physical way.
That’s because consciousness allows an object to experience its wholeness, but there is no physical explanation as to what makes an object ‘whole’, for example smooshing two brains together doesn’t result in a single consciousness any more than cutting a brain in half results in two. Yet, the same action by another mechanism (reproduction) does create a new consciousness.
I don't think there is a general consensus. In the 2020 Philpaper Survey roughly half of surveyed philosophers lean towards physicalism, roughly a third to non-physicalism, and the rest to something else.
