Abstract

In this article, I discuss some important aspects of Frege's treatment of non-extensional contexts. I focus on the analysis of belief sentences and of oratio obliqua. In the first part, I describe two types of theory within Fregean semantics and assess the analyses of non-extensional sentences of first and of second evel which can be carried out in the theories ofboth types. In the second part, I examine to what extent one can establish an infinite hierarchy of indirect senses. In the third and final part, I examine Frege's principle of substitutivity salva veritate of coreferential terms. I conclude with critica observations on articles of Tyler Burge and Jaakko Hintikka which deal with this principle.
