Having presented Frege"s reflections from "On Sense and Reference", we now turn to the principal objections which the commentators have made against Frege"s semantics. This chapter will mainly deal with those critical positions which involve the bases of the Fregean analysis: other critiques which accept the bases but cast doubt on the application will be dealt with in the following chapters. In order to maintain clarity we will answer immediately upon presentation those critiques which are clearly based on a misunderstanding. Objections which can only be met on the basis of a more thorough study of Fregean texts are clearly formulated, and then answered in the second half of the chapter.
