Qualia/Functionalism/Stalnaker: he will explain them with a relational structure. - Problem: if we could have a permutation so that the relational general structure remained - then no functionalist theory could be right.
Vs: this can be argued: 1) the relations are more complex, for example, there are relations of colors among each other - that would mean denying symmetry.
Inverted spectra/Stalnaker: bad solution: introduce additional characteristics: E.g. blue is cool - we only need the possibility of symmetry for some creatures -
functionalism: identifies Qualia intra-personnally through distinguishability.
Shoemaker: wants to reconcile interpersonal comparisons with it.
Interpersonal/Wittgenstein: from the possibility to change intra-personnally.
