De se bağlamında önermesel tutumlar ve içerikleri

This thesis develops an account of propositional attitudes and their contents that accommodates the purportedly distinctive features of de se attitudes (i.e., the first-person thoughts) and contents, thereby elucidating the scope of indexicality and context-sensitivity both in natural languages and human mind. To achieve this, I introduce two novel semantic primitives, almost-impossible and almost-necessary propositions, within the framework of a modified Lewisian-centered content and attitude semantics. This modification, which relies on these novel semantic primitives, remains compatible with the metaphysical foundations of Lewisian counterpart-theoretic semantics for quantified modal logic. The efficacy of this account is subsequently evaluated by addressing the problem of communication in de se thought, specifically the communication of first-person or self-locating thoughts across conversational participants.
