So, whether we say that two things are of the same type or are tokens of the same type because of subtle differences is just a matter of descriptive abstraction. responds to Smart's response by essentially rejecting functionalism because, he believes, it is indeed a second-order type identity theory.

Putnam uses multiple realizability against functionalism itself, suggesting that mental events (or kinds, in Putnam's terminology) may be diversely implemented by diverse functional/computational kinds; there may be only a token identification between particular mental kinds and particular functional kinds.

There are other ways a physicalist might criticize type physicalism; eliminative materialism and revisionary materialism question whether science is currently using the best categorisations.

In the same way talk of demonic possession was questioned with scientific advance, categorisations like "pain" may need to be revised.

These positions make use of the philosophical type–token distinction (e.g., Two persons having the same "type" of car need not mean that they share a "token", a single vehicle).
