Metaphysical separatism and epistemological autonomy in Frege’s philosophy and beyond

Commentators regularly attribute to Frege realist, idealist, and quietist responses metaphysical questions concerning the abstract objects he calls ‘thoughts’. But despite decades of effort, evidence offered on behalf these attributions remains unconvincing. I argue that deliberately avoids commitment any positions, as part a separatist policy motivated by fact logic is epistemologically autonomous from metaphysics. Frege’s views arguments prove relevant current attempts for epistemological autonomy, particularly ethics.
