So long as R is a physical relation, and so long as competence with the concept of consciousness does not entail knowledge of R, the materialist can maintain both the conceivability
(conceptual coherence) and the metaphysical impossibility of a zombie world.
To establish the initial conceivability
premise, Dualists can just point to the chauvinism-liberalism problem haunting IT and Functionalism.
One major philosophical problem concerns the entailment from conceivability
to so-called absolute possibility in thought experiments of theoretical philosophy: how does conceiving a scenario give evidence of its possibility LoC will address such issues via the techniques of non-classical logics with non-normal worlds semantics.
All these considerations of how self-determination is central to reason and philosophy might seem vain reveries in face of the withering objections that some of the greatest philosophers have directed at the conceivability
While this goal is perhaps commendable, readers will not get very far into Good God--perhaps to the application of Goldbach's conjecture to conceivability
limits (59-60)--without recognizing the benefits of some formal training in philosophy (and perhaps theology, for later chapters) for a full appreciation of the discussion.
unavoidability, real and fictional necessity, possible worlds, epistemic necessity, necessity de re, conceivability
Rather than directing its analysis to the conceivability
of the claim, as would have been the procedure under Conley v.
The "being" of unactualized possibility does not inhere in its relation to this or that specific mind, but to its conceivability
by mind-in-general, in terms of the linguistic resources that are a common capability of intelligence as we know it.
The argument, unsurprisingly, has certain affinities with classic idealist arguments, which treat conceivability
as a guide to ontology.
, broadly construed, plays an important role in forming modal judgements.
Gerald Massey makes a similar point in 'Backdoor Analyticity', arguing that in their use of TEs as counterexamples which appeal to conceivable states of affairs, philosophers should avoid facile conceptions and instead try to match the standards of conceivability
that have been developed in the sciences (H&M, pp.
One powerful argument for dualism is provided by Chalmers: the zombie or conceivability
Further, this can be done without relying on the notions of conceivability
or psychological law as logically relevant.
If, as Pereboom contends, the knowledge argument and the conceivability
argument presuppose that our introspective representations of consciousness are accurate, then if it is an open possibility that such representations are inaccurate, it will follow that such arguments fail to establish the falsity of physicalism.
