Melnyk’s Realization Physicalism
Qualia as Physically Realized Representational Properties
Andrew Melnyk holds that phenomenal properties are real but non-fundamental: they are multiply realizable representational properties of sensations, always realized by physical properties. He argues that the hard problem is already solved because the main anti-physicalist arguments fail, and that the lingering sense that experience cannot be physical is an ‘intuition of distinctness’ produced by the way introspection works.
Andrew Melnyk
What consciousness is
Phenomenal properties are identical to certain representational properties of sensations: the orangeness of an orange afterimage is the afterimage’s representing, in a sensory way, that something before one is orange.
Mind and body
Everything is either physical or physically realized. Mental properties are higher-order properties whose realizers are always physical but differ from case to case, as being poisonous is realized by cyanide in one substance and something else in antifreeze.
Mechanism
Physical realization, a relation stronger than supervenience and weaker than type identity with a neural property, by which the physical realizer reductively explains the mental property.
Core claims
- Physicalism is a broad-scope a posteriori hypothesis, supported by evidence rather than settled a priori.
- Every introspectable experience has a simultaneous neural correlate, and physicalism explains this dependence more economically than dualism.
- Kripke’s conceivability argument, Jackson’s knowledge argument, Levine’s explanatory gap, and Chalmers’s zombie argument are each open to serious objection, so the hard problem as precisely stated is solved.
- The intuition of distinctness arises because introspection is conceptually encapsulated, so it does not track the truth and gives no reason to accept property dualism.
Criticisms
Melnyk concedes there is no consensus that the anti-physicalist arguments fail. Dismissing the intuition of distinctness as a cognitive illusion can look self-protective, since any contrary intuition is explained away in advance.
Implications
- AI consciousness: Possible
- Since phenomenal properties are multiply realizable representational properties, a non-biological system could in principle realize them, though Melnyk’s appeal to biological function leaves open what an artificial system would need.
- Survival beyond death: No
- Everything is physical or physically realized, so experience ends when its physical realizers cease.
- Meaning and purpose: Humanistic only
- A thoroughgoing physicalism leaves no room for cosmic purpose in consciousness.
- Virtual immortality: Possible
- Multiple realizability allows that a different physical system could realize the same mental properties, though Melnyk does not address uploading.
