Let's emphasize that the made suggestions still leave many puzzles untouched. Many investigators insist that consciousness can be understood only from a first-person perspective - what it actually feels like to have certain experiences. In focusing on what conscoiusness makes possible and not on how consciousness feels, have we perhaps dodged what Chalmers has called the "hard problem" of consciousness?
Along with these ideas, some theorists have suggested that we need to distinguish types of conscious experience. Block has argued for a distinction between "phenomenal" and  "access" conscoiusness - the first concerned with the subjective experience of being conscious, and the second concerned with the functional consequences of consciousness.
