The next E-Intentionality seminar will be held Wednesday, June 8th from 13:00 to 14:50 in Pevensey 1 1A3.  Ron Chrisley will speak on “The Embodied Nature of Computation” as a dry run of his talk at a symposium (“Embodied Cognition: Constructivist and Computationalist Perspectives”) at IACAP 2016 next week:

 

Although embodiment-based critiques of computation’s role in explaining mind have at times been overstated, there are important lessons from embodiment which computationalists would do well to learn. For example, orthodox schemes for individuating computations are individualist, atemporal, and anti-semantical (formal), but considering the role of the body in cognition suggests by analogy that — even to explain extant information processing systems unrelated to cognitive science and artificial intelligence contexts — computations should instead be characterised in terms that are world-involving, dynamical and intentional/meaningful. Further, the counterfactual-involving nature of computational state individuation implies that sameness of computation is not in general preserved when one substitutes a non-living computational component with a living, autonomous, free organism that merely intends to realise the same functional profile as component being replaced. Thus, contra computational orthodoxy, there is no sharp divide between the computational facts and what is usually thought of as the implementational facts, even for unambiguously computational systems. The implications of this point for some famous disputes concerning group minds, and strong AI, will be identified.

Ron Chrisley: The Mereological Constraint

I will discuss what I call the mereological constraint, which can be traced back at least as far as Putnam’s writings in the 1960s, and is the idea, roughly, that a mind cannot have another mind as a proper constituent.  I show that the implications (benefits?) of such a constraint, if true, would be far-ranging, allowing one to finesse the Chinese room and Chinese nation arguments against computationalism, reject certain notions of extended mind, reject most group minds, make a ruling on the modality of sensory substitution, etc.  But is the mereological conjecture true?  I will look at some possible arguments for the conjecture, including one that appeals to the fact that rationality must be grounded in the non-rational, and one that attempts to derive the constraint from a comparable one concerning the individuation of computational states.  I will also consider an objection to the conjecture, that argues that it would confer on us a priori knowledge of facts that are, intuitively, empirical.
