Judaism's two native categories, narrative theology and law (also known as parable and praxis or Aggadah and Halakhah) form two distinct modes of discourse. The one expounds norms of attitude and belief, the other, norms of action and behavior. Each possesses its own modes of thought, topical program, and medium for expression. Joined together, they create a remarkably coherent statement. Any understanding of Rabbinic Judaism depends on a theory of how these two modes of thought and expression relate to form a single cogent system. Praxis and Parable explores how a single topic "the morality and law of the animal kingdom" produces two distinct vocabularies of analysis in the Rabbinic canon.
