More on "the majority" - from its classic case of kosher butchers and one non-kosher butcher. The implications and value of the principle for Halakhah at large. Also, the case of the abandoned baby - how do you determine who the baby is, whether Jewish or non-Jewish? What about the baby's lineage? That is considered a different category, as compared to saving the baby's life. What are the practical implications of assuming the baby is Jewish or not Jewish? The role "rov" plays in these kinds of cases is significant, with regard to what kind of assumptions the community can make, and what they need to do, going forward.
