Habermas claims that the concept of ?communicative action? can be explained by illocutionary acts alone. It appears tó me that his explanation collapses into a sort of intentional theory (2[i]). Habermas maintains further that a speech act consists of three components which are ?correlated? to three worlds and to three validity claims. However, he also seems to mean that all worlds and validity claims are correlated to just one; the so?called propositional component. One consequence is that the propositional content, not (...) the illocutionary act, determines the main mode of at least some speech acts. Another is that the T as used in an expressive speech act will occur in the propositional part of the act and not, as claimed by Habermas, in the performative sentence (2[iii]). In 2(ii) two other problems concerning Habermas's view on the concept of ?I? ('the subject') are discussed. (shrink)
