Article "Indirect" Information: the Debate on Testimony in Social Epistemology and Its Role in the Game of "Giving and Asking for Reasons" Raffaela Giovagnoli, Pontifical Lateran University, giovagnoli@pul.it Abstract: We'll 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 a@itudes. In particular, we'll argue for a social reformulation of the "space of reasons", which establishes a fruitful relationship with the epistemological view of Wilfrid Sellars.
