>>11603696i'm not philosophy of science guy but "explanation" i typically take to be a narrative or story to explain the connection between cause and effect in terms of beginning and ending(of the story).
in those terms we have plenty of explanations in which describe the connection between mental events and physical events.
for example: we have theories of nerves which read like a story about the connection between certain types of pain and certain types of nerve, and to connect duration and intensity of pain with topography and location of nerve. relying on such testimonies we can diagnose certain aliments based on how they feel.
what i suspect you want is a story to connect your own experienced reality with the physical processes in the brain that bring it about. again there are many such explanations, for instance i shoot you in the head and you die, or get some brain damage and lose eyesight. but this won't satisfy the question because you have an impossible desire to satisfy. what you want is a story which explains not the connection between physical and mental events, but the spatiotemporal complex in which physical events take place, and the one in which mental events take place. the physical "space" and "mental space". this is an impossible task to fulfill because explanations by nature connect events based on spatiotemporal relations, how can space itself be explained in this way? you will find similar problems to "fully" explain the beginning of the universe, running into the same dissatisfactions.
