Need knowing and acting be SSS-Safe?

Throughout the years, Sosa has taken different views on safety condition knowledge. In his early work, he endorsed condition, but later retracted this view when first developing much discussed virtue epistemology. Recently, further developed theory with notion of competence and an accompanying, modified that maintains is entailed by theory: SSS-safety condition. Sosa's holds both knowledge action, because action are manifestations competence. The roughly, says if S were to make attempt at φ-ing under certain specified shape-situation pairs, holding fixed their seat, then would φ. argument paper new does not hold either or action. We argue for conclusion providing a principled way generate counter-examples reasoning there can exist non-empty symmetric difference between sets pairs which distinct agents manifest epistemic pragmatic competences, such fails hold.
