Titre : "Frege on identity: some misconceptions and their historical origins"
Résumé : What Frege's views on identity are, as well as whether and,
if so, how they changed over the course of his career, continues to be
a matter of debate. In our recent book (Frege: Identity challenges
reflection, OUP 2025), Ulrich Pardey and I argue that Frege never
disavowed the theory of identity he proposed in Begriffsschrift and in
fact defended rather than abandoned that theory in "On sense and
reference". In earlier work ("Frege's Begriffsschrift theory of
identity vindicated," Oxford Studies in Philosophy of Language 1,
2019), we showed that, notwithstanding formal objections raised
against it throughout the history of Frege scholarship, the
Begriffsschrift theory is formally unimpeachable and, when added to
first-order logic without identity, generates the same logic as
ordinary first-order logic with identity. In my talk, I will review
some of these issues and then investigate the historical origins of
the, according to us, erroneous standard reading of Frege.
