What is it for you to be conscious? There is no agreement whatever in philosophy or science: it has remained a hard problem, a mystery. Is this partly or mainly owed to the existing theories not even having the same subject, not answering the same question? In Actual Consciousness, Ted Honderich sets out to supersede dualisms, objective physicalisms, abstract functionalism, externalisms, and other positions in the debate. He sets out a brand new theory or analysis--Actualism--which begins from accumulated data: data to the effect that being conscious in the primary ordinary sense is something's being actual. Your being conscious in perception, as distinct from thinking and wanting, is a thing external to the perceiver. Your perceptual consciousness right now probably consists in a room out there in space, a piece or stage of a subjective physical world dependent on both you and on the objective physical world. The myriad physical worlds and the objective physical world, both real, are the two divisions of the whole physical world.
