The Codification of Jewish Law and an Introduction to the Jurisprudence of the Mishna Berura, analyses the jurisprudential methodology of Rabbi Israel Meir Kagan of Radin, the author of the Mishna Berura. It also provides an introduction to the codification of Jewish law and the methodology of codification more generally. The authors demonstrate that Rabbi Kagan had a unique approach in that he tried to balance opposing forces of tradition and modernity. He also attempted to provide definitive halakhic guidance to every question of Jewish law, based on four central questions and ten halakhic principles. After a comprehensive introduction, the authors provide 250 examples from the Mishna Berura to demonstrate their findings and to clarify their thesis in practical and clear terms.
