Chalmers assumes that

"The physical domain is causally closed."<ref name="mind" />

We denote this notion of explanation by E1. Assuming some laws or theories relating to the physical domain as given (= accepted by the scientific community by and large) and referring to them as 'accepted theoretical notions', this might be put as follows:

An explanation specifies the function and structure of an explanandum

in terms of the the function and structure of accepted theoretical notions.

We refer to these phenomena as 'phenomenal aspects of consciousness':

Phenomenal aspects of consciousness are those aspects of conscious experience which do not have a function or structure, where 'function' and 'structure' are as defined above.
