"Indirect" Information: The Debate on Testimony in Social Epistemology and Its Role in the Game of "Giving and Asking for Reasons"

We will sketch the debate on testimony in social epistemology by reference to the contemporary debate on reductionism/anti-reductionism, communitarian epistemology and inferentialism. Testimony is a fundamental source of knowledge we share and it is worthy to be considered in the ambit of a dialogical perspective, which requires a description of a formal structure, which entails deontic statuses and deontic attitudes. In particular, we will argue for a social reformulation of the "space of reasons", which establishes a fruitful relationship with the epistemological view of Wilfrid Sellars.
