 Feigl’s approach to the mind-body problem became subject of extended controversy. While some authors directly contested the identity thesis as such (see, for example, Abelson 1970 and Epstein 1973; further the replies in Grünbaum 1972 and Nathanson 1972), others urged that Feigl should clarify his conception of the relation of phenomenal predicates and “raw feels.” Especially Feigl’s Minnesota collaborator Paul Meehl argued along these lines, claiming that the main problem with Feigl’s view stems from semantics (see Meehl 1966; further Aune 1966). On the whole, it can be said that identity theory was discussed from various philosophical perspectives. That Feigl left a considerable legacy can hardly be denied in this connection.
