Against Illusionism

Illusionism is the view that phenomenal qualities are an illusion. It contrasts with both dualist theories and reductive realist theories, which identify phenomenal qualities with physical or functional states. Here I defend reductive realism against three lines of objection derived from Keith Frankish, and I offer two arguments against illusionism. According to one argument, illusionism collapses into realism, and according to the other, it introduces a deep puzzle akin to the hard problem. I conclude that reductive realism is more compelling.
