 This position is not easy to take seriously; for what could be more obvious than the existence of conscious experience? Adherents of the view may respond that introspection simply leads us astray. On the basis of introspection, we believe that we undergo experiences (states with qualia in sense (1)), but the beliefs so formed are false. What would help strong illusionism here is a theory of introspection which can explain the apparent absurdity of the view. Such a theory is proposed in Kammerer 2021.
