Eliminativism is the view that our normal sense of the mind (e.g., sensations, beliefs, desires, emotions) is radically mistaken and that what we imagine to be our mental states do not exist at all. Consciousness should be eliminated, not explained. Consciousness (especially qualia) is a fiction—there is nothing real that corresponds to what we call ‘phenomenal experience.’ In Eliminativism, if we say, “I feel pain,” we are simply using outdated language. The reality is just neurobiological processes, not some inner ‘pain qualia.’ Just like science eliminated astrology and alchemy as real topics, it will eventually eliminate consciousness. Eliminativism (or eliminative materialism) is the maximalist physicalist position against consciousness. Illusionism is the view that while phenomenal consciousness (what-it's-like, inner felt experience) seems real, it is a cognitive trick played by the brain. While consciousness appears to be more than physical processes, this is a conjuring trick engineered by our introspective systems. In illusionism, when we say, “I feel pain,” we really are undergoing brain processes that generate the illusion of feeling pain-as-qualia. It’s not that the experience doesn’t happen—it just isn’t what we think it is. Eliminativism and Illusionism are closely related. Both challenge common-sense or folk-psychological notions of the mind, and both classify the phenomena as a contingent, evolutionary, inner adaptation that enhanced fitness and reproductive success. Yet, Eliminativism and Illusionism differ in subtle but important ways, particularly in what they deny and how they reinterpret subjective experience. In Eliminativism, qualia do not exist at all; in Illusionism, they seem to exist but are an illusion. Eliminativism denies the ontological reality of subjective experience; nothing corresponds to subjective experience. Illusionism accepts that experience exists functionally, but not phenomenally; the brain produces a compelling illusion of experience.
