Many philosophers and cognitive scientists dismiss the notion of qualia, sensory experiences that are internal to the brain. Leading opponents of qualia (and of Indirect Realism, the philosophical position that has qualia as a central tenet) include Michael Tye, Daniel Dennett, Paul and Patricia Churchland, and even Frank Jackson, a former supporter. Qualiaphiles apparently face the difficulty of establishing philosophical contact with the real when their access to it is seen by qualiaphobes to be second-hand and, worse, hidden behind a "veil of sensation"-a position that would slide easily into relativism and solipsism, presenting an ethical dilemma. In The Case for Qualia, proponents of qualia defend the indirect realist position and mount detailed counterarguments against opposing views.
