Editing Hard problem of consciousness (section)

==== Hard problem ====
The hard problem, in contrast, is the problem of ''why'' and ''how'' those processes are accompanied by experience.<ref name="Chalmers" /> It may further include the question of why these processes are accompanied by this or that particular experience, rather than some other kind of experience. In other words, the hard problem is the problem of explaining why certain mechanisms are accompanied by conscious experience.<ref name=":0">{{Cite book|last=Chalmers|first=David|title=The Conscious Mind|publisher=Oxford University Press|year=1996|location=New York|pages=xii–xiii, 95–106, backcover}}</ref> For example, why should neural processing in the brain lead to the felt sensations of, say, feelings of hunger? And why should those neural firings lead to feelings of hunger rather than some other feeling (such as, for example, feelings of thirst)?

Chalmers argues that it is conceivable that the relevant behaviours associated with hunger, or any other feeling, could occur even in the absence of that feeling. This suggests that experience is [[Irreducibility|irreducible]] to physical systems such as the brain. This is the topic of the next section.
