Self-Reference, Knowledge, Belief, and Modality
نویسنده
چکیده
An apparently negative result of Montague has diverted research in formal modalities away from syntactic (“first-order”) approaches, encouraging rather weak and semantically complex modal formalisms, especially in representing epistemic notions. We show that, Montague notwithstanding, consistent and straightforward firstorder syntactic treatments of modality are possible, especially for belief and knowledge; that the usual modal treatments are on no firmer ground than first-order ones when endowed with self-reference; and that in the latter case there still are remedies.
