Abstract In these short comments, I concentrate mostly on the discussion about belief retention, about Frege’s dilemma concerning sentences containing temporal indexical expressions and about the problems of cognitive significance it raises. I argue that Bozickovic’s interpretation of Perry’s proposals (both of the 70’s proposal and of its later developments) is not accurate. I offer an account of these problems that I take to be congenial with Perry’s own explanation and which I think might complement Bozickovic’s own proposal.
