A History of Qualia
The philosophers' concept of qualia is an artifact of bad theorizing, and in particular, of failing to appreciate the distinction between the intentional object of a belief (for instance) and the cause(s) of that belief. Qualia, like Santa Claus and the Easter Bunny, have a history but that does not make them real. The cause of a hallucination, for instance, may not resemble the intentional object hallucinated at all, and the representation in the brain is not rendered in special subjective properties (qualia)
