Most of the time, the texts of Torah she-be’al Peh—the Mishnah, the Tosefta, the Bavli, the Yerushalmi—provide the names of those Tannaim or Amoraim who hold a certain view, (and in doing so bring redemption to the world). But even in those cases where these sefarim don’t cite the name of the authority holding a particular view, Hazal go out of their way to track it down. This is particularly significant, since, at least in the case of the Mishnah, it was Rebbe who omitted the name of the Tanna in order to indicate that the Halakhah followed his view, and, as we know, the Gemara often notes that a particular mishnah does not follow the view of a particular Tanna. Thus, it is important to identify views that are not dominant—halakhah le-maaseh!

By ignoring the differences, the individual nature of each de’ah and shittah, we lose an important aspect of Torah.
