Abstract

The aim of the thesis is to provide the foundations for a representation-based theory of meaning, i.e. a theory of meaning that encompasses the psychological level of cognitive representations. This is in opposition to the antipsychologist goals of the Fregean philosophy of language and represents the results of a joint analysis of multiple philosophical problems in contemporary philosophy of language, which, as argued in the tesis, stem from the lack of recognition of a cognitive level in language. In the thesis, I first provide and argue a definition of cognitive/mental representations based on results in developmental psychology as well as theoretical considerations. Then, I use the definition to build upon it a richer theory of concepts and apply it to various philosophical conundra. The problems tackled include the problem of proper names (for which a solution is proposed that respects the post-Kripkean criticism), a unified meaning postulate for modalities and the epistemology and ontology of mathematical terms. The thesis concludes with a proposed application of the newly acquired framework to select social aspects of language use.
