In a recent work (Grasso et al., 2021 ), practitioners of the Integrated Information Theory (IIT) claim to have overcome the weaknesses of causal reductionism in producing a coherent account of causation, as causal reductionism would blatantly conflate causation with prediction and could not answer the question of ‘what caused what.’ In this paper, I reject such a dismissal of causal reductionism since IIT anti-reductionists misunderstand the reductionist stance. The reductionists can still invoke a causal account stemming from the causal (...) power of the universe’s basic units and interactions that, eventually, may lead to structures supporting integrated information. Additionally, I claim that the IIT-inspired misunderstanding of causal reductionism originates from the former’s metaphysical deficit, conflating information with causation. However, as a possible way out, if IIT is complemented with a deeper metaphysical ground, such as nested hylomorphism, an improved argument against causal reductionism can be made to work by invoking formal causality as the ultimate cause of integration in natural systems.

Integrated Information Theory stands out as one of the most promising theories for dealing with the hard problem of consciousness. Founded on five axioms derived from phenomenology, IIT seeks for the physical substrate of consciousness that complies with such axioms according to the criterion of maximally integrated information. Eventually, IIT identifies phenomenal consciousness with maximal Φ or, what is the same thing, with the strongest cause-effect power in the system. Among the scholars critical of this theory, some point to the (...) so-called Intrinsicality Problem, namely that consciousness cannot be an intrinsic property of the system because maximal Φ crucially depends on the possible existence of bigger values of Φ if the initial system is appropriately linked to or embedded in larger systems. Although proposals in the recent literature aim to solve the IP by going beyond reductionism and physicalism, none of them tackle the real issue, i.e., the insufficiency of IIT’s causal-metaphysical structure. This papers endeavors to provide a solution to the IP in IIT within a hylomorphist ontology that includes formal causation. Complementing IIT with formal causation provides the theory with a criterion of individuation that solves the IP and, by relaxing identification between maximal Φ and consciousness, it lends a more robust metaphysical structure. To wit, maximal Φ is a necessary but not sufficient condition for the existence of consciousness. (shrink)

Some proponents of the Integrated Information Theory of consciousness profess strong views on the Neural Correlates of Consciousness, namely that large swathes of the neocortex, the cerebellum, at least some sensory cortices, and the so-called limbic system are all not essential for any form of conscious experiences. We argue that this connection is not incidental. Conflation between strong and weak versions of the theory has led these researchers to adopt definitions of NCC that are inconsistent with their own previous definitions, (...) inadvertently betraying the promises of an otherwise fruitful empirical endeavour.

I discuss whether "sentience" (i.e., phenomenal consciousness) comes in degrees.
