 Dennett's MDM has been highly influential but has also drawn criticism, especially from those who find it insufficiently realist in its view of consciousness and at best incomplete in achieving its stated goal to fully explain it (Block 1994, Dretske 1994, Levine 1994). Many of its critics acknowledge the insight and value of the MDM, but deny that there are no real facts of consciousness other than those captured by it (Rosenthal 1994, Van Gulick 1994, Akins 1996).
