7444 | Type-type psychophysical identity is combined with a functional characterisation of pain [Lewis] |
Full Idea: The materialist theory Armstrong and I proposed joins claims of type-type psychophysical identity with a behaviourist or functionalist way of characterising mental states such as pain. | |
From: David Lewis (Mad Pain and Martian Pain [1980], §III) | |
A reaction: Armstrong has backed off from 'type-type' identity, because the realisations of a given mental state might be too diverse to be considered of the same type. Putnam's machine functionalism allows the possibility of dualism. |
