consciousness

An interesting point.  If this is true, must it necessarily follow that consciousness reduces to physical laws? or does it mean that nature cannot reduce to physical laws?  (Note: I don't believe that Penrose is a reductionist though he may well be some sort of physicalist.) 

Many hard-core materialists believe by simply categorizing all difficult-to-reduce phenomena as epiphenomena they have made "a proper place for it."  But I think this is definitional gerrymandering.
