There has been much discussion over the last decade between so-called ‘de se skeptics’ and ‘de se exceptionalists’. The debate concerns claims made by John Perry and David Lewis in 1979 on the basis of some now-famous examples they introduced. In this paper, I argue that different problems and questions have commonly been conflated when approaching these issues, and I reframe the whole debate by appealing to two theses on the transparency of mental content that have been widely overlooked. These (...) theses are essential components of the view challenged by Perry and Lewis and are indispensable for understanding the proper nature of the debates and positions in the literature. After distinguishing among three frequently conflated questions, I conclude that Perry’s and Lewis’s examples indeed present a problem for the view they were targeting, but this is not necessarily related to self-locating thoughts or indexical expressions. I also argue that our commitments to potential ‘de se thoughts’ are contingent on our positions regarding the transparency theses. I conclude the paper by exploring the prospects of an approach that, unlike most proposed views, completely abandons the idea that thoughts are relations between agents and contents. (shrink)

This thesis investigates the nature of the relation between mental representations in successful verbal communication, thought attribution, agreement, and disagreement — a relation which I call “samethinking”. The nature of samethinking raises several foundational questions about the nature of (non-natural) meaning, and the cognitive underpinnings of the emergence of culture. It bears on long-lasting puzzles in the philosophy of mind and language (such as Frege’s puzzle and Kripke’s puzzle about belief). Samethinking does not amount to sharing a reference (with “sharing" (...) I refer to two or more thinkers having something in common): it is more demanding. How can we explain and characterize this relation, more stringent than coreference, that is instantiated by a pair of thoughts when samethinking takes place? It is often assumed that this relation involves sharing a thought content more fine-grained than reference. In this thesis, I argue that the issue is more complex than what has been commonly assumed, and I suggest an alternative model in which sharing thought content is not necessary. (shrink)
