I can understand that you are adding an assumption that conscious
experience is identical to neural activity. I've understood.

Do you agree that from your perspective, human behaviour could be
explained in terms of the biological mechanism following the laws of
physics as currently envisaged, with the assumption the that the human
had no conscious experiences, or would adding that assumption effect
the explanation?
