Actually I'm only assuming my own argument contra the physical intelligibility of CTM, and my conclusion, like Maudlin's, was to reject CTM. But I'm prepared to grant Bruno's reversal of matter and mathematics as a working hypothesis to retain the possibility of a computational mind-body theory, to be justified abductively. >>.If it >> were to turn out somehow that the mind-body problem and the whole of >> physics besides could be elucidated by the explanatory power of comp >> on the basis of AR+UDA+CT etc then what could the posit of Platonism >> add to this? > > Platonism=AR.

AR as we have defined it is unambiguously a posit of comp. Labelling this "Platonism" can provide nothing further in the way of illumination, but I follow Popper in holding arguing about words to be futile, so I won't. >> Of course how all this would connect with RITSIAR is >> unlikely to be settled by such an approach; but this is either the HP, >> which seems intractable on any purely processual basis (for those who >> take it seriously) or else would already be explained (for those who >> don't). > > You have answered your own question.

Ah, if you are proposing that, beyond theoretical and methodological constraints, any metaphysical posit per se could disambiguate what is RITSIAR, I must disagree. In developing third-person accounts of persons and states of affairs, we seek to explicate consistent nomological relations between the posited theoretical entities. But beyond this, the connection between RITSIAR and any third-person account remains a mystery in the face of any known explanatory strategy. It does not seem susceptible to causal association with processes or events in any intelligible sense, nor does the posit of unsupported 'identities', between entities radically non-identical by any consistent standard, seem more effective than a whistle in the dark. Hence I think it may be missing the point to insist that any theoretical entity deployed for the purpose of a third-person account is itself RITSIAR; rather we should regard such accounts as successful insofar as they take us ever closer to the brink of the gap, on the other side of which RITSIAR can be glimpsed.
