After clarifying the importance of the issue in a larger context of logical theories, the paper investigates the following question: Why do we encounter a more contentious debate on the logical constancy of quantifiers than in the case of sentential connectives? Starting from the intuitive and ...

I.e., Frege invites us to identify sentences with names of truth values and to view the logical connectives as truth value operators corresponding to truth-functions. Therefore, in Frege’s later writings, only an expression of the form ‘├φ’ represents a full judgment. As such, it does...
