Idea that functions can be achieved without contingency of particular material or physical medium; used to argue sentience need not require neural tissue.

Frameworks (4)

framework

Integrated Information Theory
contradicts
Tononi et al. framework quantifying consciousness via integration; provides mathematical tools for measuring agent complexity.
Computational Functionalism
supports
Hypothesis that some class of computations suffices for consciousness; central assumption for AI consciousness route.
Biological Naturalism
contradicts
Searle and Seth's position that consciousness requires specific biological/autopoietic processes; explicitly rejected by CIMC on functionalist grounds
Principle of Computational Equivalence
supports
Wolfram's principle that systems above a low threshold of complexity are computationally equivalent, supporting substrate independence of consciousness

Claims (1)

claim

Cognitive functions, including sentience, can potentially be achieved by very different systems and their disparate substrates.
supports
Central multiple-realizability claim of the paper, from abstract and §2.

Concepts (4)

concept

Sentience
supports
Central concept: the capacity to experience as a subject; core focus of the paper's argument about multiple substrates.
Multiple Realizability
associated_with
Philosophical framework asserting same function can be implemented by very different systems; key to arguing sentience is substrate-independent.
Connectionism
associated_with
Central framework proposing intelligence resides in organization of relationships between components, not in individual parts; used to unify individual and collective intelligence.
Church-Turing Thesis
supports
Establishes that all constructive formalizations of computation are equivalent; grounds the claim that consciousness can be realized on any universal computing substrate
