  While pursuing his investigations into mathematics and logic (and quite possibly, in order to ground those investigations), Frege was led to develop a philosophy of language. His philosophy of language has had just as much, if not more, impact than his contributions to logic and mathematics. However, Bobzien (2021) offers compelling documentation suggesting that significant elements of Frege’s philosophy of language were adapted from Stoic logic.  In this section, therefore, we first rehearse a key element of Frege’s philosophy of language, namely, the distinction between sense and denotation.  To motivate this distinction, we go through the two key puzzles Frege attempted to solve (Section 3.1) and then examine how the distinction between the sense and denotation of terms (and sentences) solve these puzzles (Section 3.2). Finally, we attempt to put Frege’s philosophy of language in context (Section 3.3), in light of new research arguing for the significant influence that (discussions of) Stoic texts had on his ideas.
