Book Journeys, Some Updates, and the Hoshanot Mosh Pit

The episode begins with some updates. First, an introduction to the "Book Journey" that I will begin next week. Sign up link: https://18forty.org/bookjourney/ This is an outgrowth of the 18forty podcast episode in which R. David Bashevkin and I discussed the vision and reality of a Jewish polity governed by Halakhah. Here's a link to the episode: https://18forty.org/podcast/elli-fischer-can-israel-follow-jewish-law/ I was also a recent guest on two other podcasts. First, Rav David Silverstein and I discussed the nature of rabbinic authority on Yeshivat Orayta's "Tzarich Iyun" podcast: https://open.spotify.com/episode/71aX8L9IA2j1QY78dOoGff?si=577b0ae9ed414716 Finally, a few months ago I was hosted by Darcy Walters for an episode of her "Desert Island Torah" podcast. Here's a link: https://podcasters.spotify.com/pod/pod/show/desert-island-torah/episodes/Ep-81-with-Rav-Elli-Fischer-e23me3f The responsum that we study in this episode was penned by R. Yisrael Isserlein, better known as the Terumat HaDeshen. We spend some time discussing when and where he lived, who his influences were, why his rulings are so influential, and what makes his Sefer Terumat HaDeshen so unique. Then we go on to the teshuvah itself, which addresses an issue that is not-quite-halakhah. The setting is almost surreal: Person A allegedly used the crush of hoshanot in shul as cover to maim Person B while maintaining plausible deniability. This is an important matter of social and communal governance, but halakhic standards of evidence seem to set too high a bar to take any action. How did R. Isserlein resolve the matter? Here's a link to the teshuvah in Sefariah, with my translation: https://www.sefaria.org.il/Terumat_HaDeshen%2C_Part_II.210?lang=bi
