Book excerpt: The initial impetus for writing this book was the desire to understand more fully and completely the contribution of the redactors of the Talmud, the Stammaim. It was this desire to appreciate the redactors' innovations along with the indebtedness to their predecessors that made me reexamine the nature of both Midrashic and Mishnaic forms, place them in their proper historical perspective, and relate them to the source of all Jewish knowledge, the Bible.
