Abstract

Greco argues that knowledge by transmission involves joint agency whose norms are governed by the quality of the social relations in the transmission, and these norms differ from the norms generating knowledge in the source. This approach to the transmission of knowledge allows Greco to respond to three common arguments against the rationality of religious belief on testimony: the argument against belief in miracles, the argument from luck, and the argument from peer disagreement. I agree with Greco’s position on the transmission of knowledge or reasonable belief in these cases and argue that the distinction between first person and third person reasons for belief can strengthen his position. The experience upon which a belief is based can be transferred intersubjectively and strengthens the ground for the belief based on experience, including the belief in miracles. Trust is another first person reason for belief, not only a background condition for reasonable transmission, and it also can be transmitted and is an important component in the formation and preservation of traditions. This feature permits a reply to the arguments from luck and from disagreement with people outside the tradition. But this feature also shows why we find these arguments threatening since we are rationally committed to a minimal degree of trust in all other reasonable persons.
